In an embodiment of the present application, obtaining the target serial number corresponding to the abnormal transaction in the case of detecting that there is an abnormal transaction in the plurality of transactions includes: in the case of detecting that there is an abnormal transaction in the plurality of transactions, obtaining The current message generated by the above-mentioned abnormal transaction during the transaction process; obtain the above-mentioned target serial number contained in the above-mentioned message, wherein the above-mentioned target serial number includes the global business tracking number corresponding to the above-mentioned abnormal transaction and the sub-transaction sequence number corresponding to the above-mentioned abnormal transaction , the above-mentioned global business tracking number runs through the entire transaction process corresponding to the above-mentioned abnormal transaction. When making a cross-system call, the standard public message will be used to record the key fields required for the transaction. The target serial number belongs to the key field that needs to be recorded. Therefore, the above target serial number can be obtained from the current message. The above target serial number The serial number includes the global business tracking number and sub-transaction serial number throughout the entire transaction process of the abnormal transaction. This embodiment does not need to generate a new target serial number and is directly obtained from the current message, thereby realizing a system for quickly locating transaction abnormality.

In order to obtain accurate abnormal transaction information, in yet another embodiment of the present application, locating the above abnormal transaction according to the above target serial number to determine the above abnormal transaction information includes: analyzing the above global business tracking number, and obtain a first analysis result, wherein the first analysis result includes at least a time stamp, a first system number, a first transaction instance serial number and a serial number, and the above time stamp is the time stamp corresponding to the abnormal transaction when the transaction is initiated, and the above The first system number is the identification code corresponding to the system of the original initiator of the above abnormal transaction, the above first transaction instance serial number is the identification code of the machine where the transaction instance corresponding to the above abnormal transaction is located, and the above serial number is the above abnormal transaction when the above abnormal transaction is initiated. The cyclically incremented serial number generated by the original initiator's system; according to the above-mentioned first analysis result, the information of the above-mentioned abnormal transaction is determined. The global business tracking number is generated by the trigger point, and lasts consistently until the time completes. Therefore, the information about the above abnormal transaction is recorded in the global business tracking number. Therefore, in this embodiment, the global business tracking number needs to be parsed first to obtain the first According to the analysis result, the abnormal transaction information recorded in the global business tracking number can be obtained according to the first analysis result.

The above-mentioned global business tracking number may be used as the primary key of the database in the system. For the primary key of the database, the length of the primary key should not be too long. In addition, considering that there are many components of the global business tracking number, a specific In the embodiment, the above-mentioned global service tracking number is set to 32 bits. The composition of the above global service tracking number is shown in Table 1:

Table I

The above timestamp: generated by obtaining the local system time, which belongs to the technical field.

The above system number: All systems are arranged according to the division of business functions. It is a code with business attributes. This part consists of 7 digits, which is derived from a unified standard. For example, the deposit system uses "1111111" and the remittance system uses "2222222". Used, the system number in the global business tracking number is generated by the transaction initiator.

The above transaction instance serial number: This component belongs to the technical field. The generation process is shown in Figure 3. When initiating the acquisition of the transaction instance serial number, it is first obtained from the local environment variable. The above environment variable is an environment parameter configured in the server. If it exists, it will return directly. If it does not exist, it will be obtained from the system startup. If the configuration of the transaction instance serial number exists in the startup parameters, it will be returned directly. If it does not exist, it will be generated by the local default algorithm. The transaction instance serial number in the global business tracking number is generated by the transaction initiator.

Generation of the above-mentioned serial number: In this application, the serial number is used cyclically, and the flow of its generation is shown in FIG. 4 . The serial number is self-incremented using Java's native AtomicInteger. The result obtained after self-increment is judged whether it is greater than 999999. If it is greater than 1, the serial number is set to 1 and the string is formatted. If it is not greater than 999999, the obtained result is character string format to generate the final serial number.

The generated global business tracking number is obtained by splicing the 14-digit timestamp, 7-digit system code, 5-digit transaction instance serial number and 6-digit serial number generated above. As shown in Figure 5, suppose there is a transaction, and its transaction link is shown in the figure below. If system A is the transaction initiator, system A will generate the global business tracking number for this transaction, and system B and system C will not generate the global business tracking number again. Each inter-system call in the transaction sends the global business tracking number to the downstream system.

In another embodiment of the present application, as shown in FIG. 6 , before locating the abnormal transaction according to the target serial number to determine the information of the abnormal transaction, the method further includes: acquiring the original data corresponding to the abnormal transaction. MAC address corresponding to the machine where the transaction instance is located; calculate the hash value corresponding to the above MAC address, and perform a modulo operation on the above hash value to obtain a modulo result; perform a zero-fill operation on the above modulo result to obtain the above-mentioned first transaction instance serial number . In this embodiment, the hash value is calculated based on the MAC address of the machine where the original transaction instance is located, then a modulo operation is performed on the hash value, and a zero-fill operation is performed on the result of the modulo operation, thereby obtaining an accurate first transaction embodiment serial number .

For example, if the transaction instance serial number is 5 digits, then modulo 99999 (five 9s), if the transaction instance serial number is 6 digits, then take the modulo 999999 (six 9s). Finally, string formatting (that is, zero-filling operation) is performed on the modulo result to complete the generation of the transaction instance serial number.

In addition, the above-mentioned method for determining the serial number of the first transaction instance further includes acquiring from a configuration parameter activated by the service and acquiring from an environment variable configuration.

In another embodiment of the present application, locating the above-mentioned abnormal transaction according to the above-mentioned target serial number, so as to determine the corresponding calling system when the above-mentioned abnormal transaction occurs abnormally in the transaction link, includes: obtaining the information contained in the above-mentioned target serial number. The target sub-transaction sequence number in the plurality of sub-transaction sequence numbers, wherein the target sub-transaction sequence number is the current sub-transaction sequence number generated during the transaction process of the abnormal transaction; analyze the target sub-transaction sequence number, and obtain a second analysis result , wherein the second analysis result at least includes the second system number, the second transaction instance serial number and the latest transaction arrangement number, and the second system number is the identification code corresponding to the current calling initiator system corresponding to the abnormal transaction, the first 2. The transaction instance serial number is the identification code of the machine where the transaction instance corresponding to the above abnormal transaction generated by the above-mentioned current invocation originator system is located, and the above-mentioned latest transaction arrangement number represents the invocation link to the system in the current invocation process from the horizontal and vertical dimensions; According to the second analysis result, the calling system corresponding to the abnormal transaction in the transaction link is determined. In this embodiment, it is necessary to obtain the second system number, the second transaction instance serial number and the latest transaction arrangement number from the above-mentioned target sub-transaction serial numbers. The call initiation system of the abnormal transaction and the transaction link of the call process can be located, thereby realizing the rapid location of the abnormal call system in the complex link.

The above-mentioned target sub-transaction sequence number includes the second system number, the second transaction instance sequence number and the latest transaction arrangement number. The above target sub-transaction sequence number is mainly used to identify each calling sub-branch of a transaction. The composition of the above target sub-transaction serial numbers is shown in Table 2:

Table II

The difference between the second system number and the system number in the global service tracking number is that the second system number is generated by the current calling initiator system.

The method for generating the transaction instance serial number is the same as the method for generating the global business tracking number above, but the difference is that the transaction instance serial number is generated by the calling initiator system.

The latest transaction number listed above consists of letters and numbers. The latest transaction sequence number has a total of 20 digits, indicating that the transaction level number supports a maximum of 20 layers. The character value range of each digit in the latest transaction sequence number is "1-9, A-Z", indicating that the maximum number of transaction instances at the same level supports 35. The latest transaction arrangement number represents the call link of the transaction from the horizontal and vertical dimensions, and the latest transaction arrangement number is passed along the transaction link. The initial value of the latest transaction arrangement number is all 0. Every time a system call occurs on the transaction link, the latest transaction arrangement number will be upgraded or upgraded.

In yet another embodiment of the present application, before locating the abnormal transaction according to the target serial number to determine the corresponding calling system when the abnormal transaction occurs abnormally in the transaction link, the method includes: acquiring the abnormal transaction The current system call information corresponding to the transaction link, the current system call information includes at least the information of the current call originator system corresponding to the abnormal transaction and the information of the current called system; according to the current system call information, generate The sequence number of the above target sub-transaction. In this embodiment, the above-mentioned target sub-transaction sequence number is generated according to the calling information of the current system, so the system in which the abnormal transaction occurs can be located according to the above-mentioned target sub-transaction sequence number, thereby locating the abnormal invocation system more quickly.

In a specific embodiment of the present application, after receiving the message transmitted by the upstream system, the sub-transaction sequence number in the message is stored in a custom context, and the custom context uses the JAVA native ThreadLocal class to accomplish. ThreadLocal is a storage class inside a thread, which can store data in a specified thread. After the data is stored, only the specified thread can get the stored data. ThreadLocal has a separate storage space for each thread. It has the effect of thread isolation. The corresponding value can only be obtained within the thread, and the desired value cannot be accessed outside the thread. Therefore, the current thread performing the transaction can obtain the sub-transaction sequence number transmitted from the upstream system to the current system through the self-defined context.

The data structure of the stack is created in the custom context, which is used to store the newly generated sub-transaction sequence number, which is recorded as the sub-transaction sequence number stack. The number of sub-transaction sequence numbers stored in the stack at the beginning is 0. Each time a new sub-transaction sequence number is generated, the sub-transaction sequence number is pushed into the stack, and the element at the top of the stack is always the latest sub-transaction sequence number. It should be noted that there are a total of two attributes in the custom context to store the sub-transaction sequence number, which are respectively denoted as subTxNo and subTxNoStack in this application. The difference between the two attributes is shown in Table 3 below.

Table 3

When it is necessary to upgrade the sub-transaction sequence number, it is mainly judged by whether the number of elements in the sub-transaction sequence number stack subTxNoStack is 0. If it is 0, it means that the current system has not generated the sub-transaction sequence number, which means that the current system is the first call outside. system, then carry out the logic of upgrading. When upgrading, you need to take out the sub-transaction serial number subTxNo transmitted from the upstream system to this system from the custom context, use it as the benchmark, complete the sub-transaction serial number upgrade logic in the above chapter, and finally push the newly generated sub-transaction serial number into the The sub-transaction sequence number stack of the custom context is in subTxNoStack.

When the sub-transaction sequence number increases, it is also judged by whether the number of elements in the sub-transaction sequence number stack subTxNoStack is 0. If it is not 0, it means that the current system has generated the sub-transaction sequence number, indicating that the current system is not the first call. If the external system is used, the logic of ascending order is performed. When ascending the order, you need to obtain the sub-transaction serial number on the top of the stack from the sub-transaction serial number stack subTxNoStack. Based on the sub-transaction serial number, complete the logic of the ascending order of the sub-transaction serial number in the above chapter, and finally push the newly generated sub-transaction serial number into Sub-transaction serial number stack subTxNoStack.

When the calling system needs to generate a sub-transaction sequence number, it returns the top element of the sub-transaction sequence number stack of the custom context to the system.

In another embodiment of the present application, generating the target sub-transaction sequence number according to the current system invocation information includes: acquiring an identification code corresponding to the current invocation initiator system, and determining the identification code as the target sub-transaction sequence number generate the above-mentioned target sub-transaction serial number to obtain the transaction instance serial number; determine that the above-mentioned current system is at the level of the above-mentioned transaction link, and determine the level number corresponding to the above-mentioned level; The characters other than the above-mentioned prefix and the above-mentioned level number are set to 0, so as to generate the reference sequence number corresponding to the above-mentioned target sub-transaction sequence number; obtain the calling situation of the above-mentioned current calling initiator system calling the above-mentioned currently called system, and according to the above-mentioned calling situation. Adjustment; determine the above-mentioned benchmark serial number after adjustment as the above-mentioned target sub-transaction serial number. In this embodiment, first determine the prefix of the calling and issuing system and the level number at the exchange, then determine the number of characters in the sequence number of the target sub-transaction, arrange the above prefix and the above level number in sequence, and determine to remove the above prefix and the above The character other than the level number is 0, so that the target sub-transaction sequence number is generated, so that from the generated target sub-transaction sequence number, the calling initiator system can be quickly located through the prefix. Thereby, the abnormal system can be located more quickly.

The above-mentioned target sub-transaction sequence number generation process is as follows: Take the transaction link shown in Figure 7 as an example, this link focuses on the generation process of the latest transaction sequence number, and uses the corresponding system number and transaction instance sequence number in the sub-transaction sequence number uniformly. For example, system A uses the letter "A" to represent its system number and transaction instance serial number, system B uses the letter "B" to represent its system number and transaction instance serial number, and so on.

(1) System A, as the transaction initiator, generates the first sub-transaction serial number of this transaction, and the sub-transaction serial number is "A1000000000000000000". System A is the transaction initiator, and its transaction level number is 1, so the first digit in the corresponding latest transaction number is 1, and the last 19 digits are 0;

(2) System A first calls system B, then calls system C, and then calls system D.

At this time, three new sub-transaction sequence numbers need to be generated to represent the three call branches. The system number and transaction instance sequence number in the three sub-transaction sequence numbers are generated by system A, so the prefixes of the sub-transaction sequence numbers are all A. For the first time, system A calls system B, which is the first time that system A calls an external system. Therefore, the logic of upgrading is required. Based on the first sub-transaction serial number "A1000000000000000000", according to the above-mentioned upgrading logic, the obtained sub-transaction The serial number is "A110000000000000000"; the second time, system A calls system C, and non-system A calls the external system for the first time, so the logic of ascending order needs to be performed. The sub-transaction serial number is "A1200000000000000000"; the third time, system A calls D, and non-system A calls the external system for the first time, so the logic of ascending order needs to be performed. , the obtained sub-transaction serial number is "A1300000000000000000".

(3) System B calls system E, and system B calls system F. In this case, two new sub-transaction sequence numbers need to be generated to represent the two calling sub-branches. The system number and transaction instance sequence number in the two sub-transaction sequence numbers are both generated by system B. For the first time, system B calls system E, which is the first time that system B calls an external system. Therefore, the logic of upgrading is required. The previous sub-transaction serial number "A1100000000000000000" is the benchmark. According to the upgrading logic, the generated sub-transaction serial number is " B1110000000000000000"; the second time, system B calls system F, and non-system B calls the external system for the first time, so the logic of ascending order needs to be performed. The serial number is "B1120000000000000000".

(4) System D calls system G. At this time, a new sub-transaction sequence number needs to be generated to represent the calling sub-branch. The system number and transaction instance sequence number of the sub-transaction sequence number are generated by system D. System D calls system G, which is the first time that system D calls an external system. Therefore, the logic of upgrading is required. Based on the previous sub-transaction serial number "A1300000000000000000", according to the upgrading logic, the obtained sub-transaction serial number is "D1310000000000000000". So far, the latest transaction arrangement number generation process for this transaction link has been completed.

Taking the target sub-transaction serial number "D1310000000000000000" generated above as an example, you can first know that the system caller is system D; in the last 20 digits of the latest transaction number, there are a total of 3 non-zero characters, indicating that the current system is in the transaction The transaction level number in the link is 3; find the position where the character 0 appears first from left to right in the latest transaction arrangement number, and record it as pos.

The above system number: All systems are arranged according to the division of business functions. It is a code with business attributes. This part consists of 7 digits, which is derived from a unified standard. For example, the deposit system uses "1111111" and the remittance system uses "2222222". Used, the system number in the global business tracking number is generated by the transaction initiator.

The above transaction instance serial number: This component belongs to the technical field. The generation process is shown in Figure 3. When initiating the acquisition of the transaction instance serial number, it is first obtained from the local environment variable. The above environment variable is an environment parameter configured in the server. If it exists, it will return directly. If it does not exist, it will be obtained from the system startup. If the configuration of the transaction instance serial number exists in the startup parameters, it will be returned directly.

If it is greater than 1, the serial number is set to 1 and the string is formatted. If it is not greater than 999999, the obtained result is character string format to generate the final serial number.

The generated global business tracking number is obtained by splicing the 14-digit timestamp, 7-digit system code, 5-digit transaction instance serial number and 6-digit serial number generated above. As shown in Figure 5, suppose there is a transaction, and its transaction link is shown in the figure below. If system A is the transaction initiator, system A will generate the global business tracking number for this transaction, and system B and system C will not generate the global business tracking number again.

In another embodiment of the present application, the positioning unit includes a third acquisition subunit, a second analysis subunit, and a second determination subunit, wherein the third acquisition subunit is used to acquire the target serial number included in the The target sub-transaction sequence number in the plurality of sub-transaction sequence numbers, wherein the target sub-transaction sequence number is the current sub-transaction sequence number generated during the transaction process of the abnormal transaction; the second parsing sub-unit is used to analyze the target sub-transaction sequence number. Parse, and obtain a second parsing result, wherein the second parsing result at least includes the second system number, the second transaction instance serial number, and the latest transaction arrangement number, and the second system number is the current calling initiator corresponding to the abnormal transaction.

The above-mentioned target sub-transaction sequence number includes the second system number, the second transaction instance sequence number and the latest transaction arrangement number. The above target sub-transaction sequence number is mainly used to identify each calling sub-branch of a transaction. The composition of the above target sub-transaction serial numbers is shown in Table 2:

The latest transaction sequence number has a total of 20 digits, indicating that the transaction level number supports a maximum of 20 layers. The character value range of each digit in the latest transaction sequence number is "1-9, A-Z", indicating that the maximum number of transaction instances at the same level supports 35. The latest transaction arrangement number represents the call link of the transaction from the horizontal and vertical dimensions, and the latest transaction arrangement number is passed along the transaction link.

In a specific embodiment of the present application, after receiving the message transmitted by the upstream system, the sub-transaction sequence number in the message is stored in a custom context, and the custom context uses the JAVA native ThreadLocal class to accomplish. ThreadLocal is a storage class inside a thread, which can store data in a specified thread. After the data is stored, only the specified thread can get the stored data. ThreadLocal has a separate storage space for each thread. It has the effect of thread isolation. The corresponding value can only be obtained within the thread, and the desired value cannot be accessed outside the thread. Therefore, the current thread performing the transaction can obtain the sub-transaction sequence number transmitted from the upstream system to the current system through the self-defined context.

The data structure of the stack is created in the custom context, which is used to store the newly generated sub-transaction sequence number, which is recorded as the sub-transaction sequence number stack. The number of sub-transaction sequence numbers stored in the stack at the beginning is 0. Each time a new sub-transaction sequence number is generated, the sub-transaction sequence number is pushed into the stack, and the element at the top of the stack is always the latest sub-transaction sequence number. It should be noted that there are a total of two attributes in the custom context to store the sub-transaction sequence number, which are respectively denoted as subTxNo and subTxNoStack in this application. The difference between the two attributes is shown in Table 3 below.

Table 3

When it is necessary to upgrade the sub-transaction sequence number, it is mainly judged by whether the number of elements in the sub-transaction sequence number stack subTxNoStack is 0. If it is 0, it means that the current system has not generated the sub-transaction sequence number, which means that the current system is the first call outside. system, then carry out the logic of upgrading. When upgrading, you need to take out the sub-transaction serial number subTxNo transmitted from the upstream system to this system from the custom context, use it as the benchmark, complete the sub-transaction serial number upgrade logic in the above chapter, and finally push the newly generated sub-transaction serial number into the The sub-transaction sequence number stack of the custom context is in subTxNoStack.

When the sub-transaction sequence number increases, it is also judged by whether the number of elements in the sub-transaction sequence number stack subTxNoStack is 0. If it is not 0, it means that the current system has generated the sub-transaction sequence number, indicating that the current system is not the first call. If the external system is used, the logic of ascending order is performed. When ascending the order, you need to obtain the sub-transaction serial number on the top of the stack from the sub-transaction serial number stack subTxNoStack. Based on the sub-transaction serial number, complete the logic of the ascending order of the sub-transaction serial number in the above chapter, and finally push the newly generated sub-transaction serial number into Sub-transaction serial number stack subTxNoStack.

When the calling system needs to generate a sub-transaction sequence number, it returns the top element of the sub-transaction sequence number stack of the custom context to the system.

In another embodiment of the present application, the generating unit includes a fourth acquiring subunit, a first generating subunit, a third determining subunit, a fourth determining subunit, a fifth determining subunit, a second generating subunit, The fifth acquisition subunit and the sixth determination subunit, wherein the fourth acquisition subunit is used to acquire the identification code corresponding to the current call initiator system, and determine the identification code as the prefix of the target sub-transaction sequence number; the above The first generation subunit is used to generate the above-mentioned target sub-transaction sequence number to obtain the transaction instance sequence number; the above-mentioned third determination subunit is used to determine that the above-mentioned current system is at the level of the above-mentioned transaction link, and to determine the level number corresponding to the above-mentioned level; the above-mentioned The fourth determination subunit is used to determine the number of the current system at the current level of the transaction link; the fifth determination subunit is used to determine the number of characters contained in the target sub-transaction sequence number; the second generation subunit is used for The above-mentioned prefix and the above-mentioned level number are arranged in sequence, and the characters other than the above-mentioned prefix and the above-mentioned level number are determined to be 0, so as to generate the reference sequence number corresponding to the above-mentioned target sub-transaction serial number; the above-mentioned fifth obtaining subunit is used to obtain the above-mentioned current call The initiator system invokes the invocation status of the current called system, and adjusts the reference sequence number according to the invocation status; the sixth determination subunit is used to determine the adjusted reference sequence number as the target sub-transaction sequence number. In this embodiment, first determine the prefix of the calling and issuing system and the level number at the exchange, then determine the number of characters in the sequence number of the target sub-transaction, arrange the above prefix and the above level number in sequence, and determine to remove the above prefix and the above The character other than the level number is 0, so that the target sub-transaction sequence number is generated, so that from the generated target sub-transaction sequence number, the calling initiator system can be quickly located through the prefix. Thereby, the abnormal system can be located more quickly.

The above-mentioned target sub-transaction sequence number generation process is as follows: Take the transaction link shown in Figure 7 as an example, this link focuses on the generation process of the latest transaction sequence number, and uses the corresponding system number and transaction instance sequence number in the sub-transaction sequence number uniformly. For example, system A uses the letter "A" to represent its system number and transaction instance serial number, system B uses the letter "B" to represent its system number and transaction instance serial number, and so on.

(1) System A, as the transaction initiator, generates the first sub-transaction serial number of this transaction, and the sub-transaction serial number is "A1000000000000000000". System A is the transaction initiator, and its transaction level number is 1, so the first digit in the corresponding latest transaction number is 1, and the last 19 digits are 0;

(2) System A first calls system B, then calls system C, and then calls system D.

At this time, three new sub-transaction sequence numbers need to be generated to represent the three call branches. The system number and transaction instance sequence number in the three sub-transaction sequence numbers are generated by system A, so the prefixes of the sub-transaction sequence numbers are all A. For the first time, system A calls system B, which is the first time that system A calls an external system. Therefore, the logic of upgrading is required. Based on the first sub-transaction serial number "A1000000000000000000", according to the above-mentioned upgrading logic, the obtained sub-transaction The serial number is "A110000000000000000"; the second time, system A calls system C, and non-system A calls the external system for the first time, so the logic of ascending order needs to be performed. The sub-transaction serial number is "A1200000000000000000"; the third time, system A calls D, and non-system A calls the external system for the first time, so the logic of ascending order needs to be performed. , the obtained sub-transaction serial number is "A1300000000000000000".

(3) System B calls system E, and system B calls system F. In this case, two new sub-transaction sequence numbers need to be generated to represent the two calling sub-branches. The system number and transaction instance sequence number in the two sub-transaction sequence numbers are both generated by system B. For the first time, system B calls system E, which is the first time that system B calls an external system. Therefore, the logic of upgrading is required. The previous sub-transaction serial number "A1100000000000000000" is the benchmark. According to the upgrading logic, the generated sub-transaction serial number is " B1110000000000000000"; the second time, system B calls system F, and non-system B calls the external system for the first time, so the logic of ascending order needs to be performed. The serial number is "B1120000000000000000".

(4) System D calls system G. At this time, a new sub-transaction sequence number needs to be generated to represent the calling sub-branch. The system number and transaction instance sequence number of the sub-transaction sequence number are generated by system D. System D calls system G, which is the first time that system D calls an external system. Therefore, the logic of upgrading is required. Based on the previous sub-transaction serial number "A1300000000000000000", according to the upgrading logic, the obtained sub-transaction serial number is "D1310000000000000000". So far, the latest transaction arrangement number generation process for this transaction link has been completed.

Taking the target sub-transaction serial number "D1310000000000000000" generated above as an example, you can first know that the system caller is system D; in the last 20 digits of the latest transaction number, there are a total of 3 non-zero characters, indicating that the current system is in the transaction The transaction level number in the link is 3; find the position where the character 0 appears first from left to right in the latest transaction arrangement number, and record it as pos. The first system called by system D.

In order to locate the abnormal system more quickly, in another embodiment of the present application, the fifth acquisition subunit includes a judgment module, a first adjustment module, and a second adjustment module, wherein the judgment module is used to judge the current When the calling initiator system calls the above-mentioned currently called system, whether the above-mentioned current calling initiator system is the first time to call the external system; the above-mentioned first adjustment module is used to call the above-mentioned external system for the first time when the above-mentioned current calling initiator system is the first time to call the above-mentioned external system, The above-mentioned reference serial number is upgraded to make the character whose first digit is 0 in the above-mentioned reference serial number is converted into 1; the above-mentioned second adjustment module is used to call the above-mentioned external system when the above-mentioned current calling initiator system is not the first time. An ascending process is performed on the above-mentioned reference serial number to adjust the level number in the above-mentioned reference serial number plus 1. In this embodiment, according to whether the above-mentioned calling initiator system is the first call to the external system to perform the upgrade logic or the upgrade logic, the calling status of the current system can be obtained according to the first digit in the reference sequence number and the level number.

In a specific embodiment of the present application, the above-mentioned upgrade logic is shown in FIG. 8 . It is necessary to find the first position where the character 0 appears in the latest transaction number from left to right. If the position exists, the character If 0 is changed to 1, the upgrade logic of the latest transaction arrangement number is completed. If this position does not exist, it means that the transaction level number has reached the maximum, and the upgrade cannot be continued.

In another specific embodiment of the present application, the above-mentioned ascending logic is shown in FIG. 9 . First, the position where the character 0 appears first is found in the latest transaction arrangement number from left to right, which is denoted as pos. If pos exists, obtain the character at the position of pos minus 1, and then judge whether the character is counted by Z, and the base operation is performed. If it is Z, it means that the number of transaction instances at the same level has reached the maximum. auto increment. It should be noted that when the character is auto-incremented, when the character is 9, the result of the auto-increment is A. If pos does not exist, obtain the last character in the latest transaction arrangement number, and then judge whether the character is Z, and the following steps are the same as the previous steps.
