Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings. The exemplary embodiments of the present invention and their descriptions herein are for the purpose of explaining the present invention, but are not to be construed as limiting the invention. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be arbitrarily combined with each other.
Fig. 1 is a schematic structural diagram of an online transaction processing system according to an embodiment of the present invention, and as shown in fig. 1, the online transaction processing system according to an embodiment of the present invention includes a foreground application system 1, a switching server 2, and a middle-background application system 3, wherein:
the foreground application 1 comprises at least one foreground terminal 11 and the background application 3 comprises at least one application server 31. The switching server 2 is communicatively connected to each of the foreground terminals 31, and the switching server 2 is communicatively connected to each of the application servers 31. The front-end terminal 11 includes, but is not limited to, a desktop computer, a notebook computer, a server, and the like.
Each foreground terminal 11 may send an online transaction request to the switching server 2, where the switching server 2 executes the online transaction processing method provided in the embodiment of the present invention. The mid-background application system 3 switches between the memory-level asynchronous processing mechanism and the database-level asynchronous processing mechanism according to the first switching instruction or the second switching instruction sent by the switching server 2. Wherein the memory-level asynchronous processing mechanism and the database-level asynchronous processing mechanism are preconfigured to the mid-background application system 3.
The memory-level asynchronous processing mechanism refers to that the application server 31 in the background application system 3 directly writes the received online transaction request into the memory, and then performs corresponding processing. The online transaction requests are processed by adopting a memory-level asynchronous processing mechanism, so that the risk of memory overflow exists, if the processing time of a certain online transaction request is too long, the subsequent online transaction requests are always written into the memory, and after the number of the online transaction requests is accumulated to a certain number, the memory overflow is caused. Therefore, the online transaction processing method provided by the embodiment of the invention limits the online transaction request through the memory-level transaction execution rule so as to avoid memory overflow.
The database-level asynchronous processing mechanism refers to that in the background application system 3, the application server 31 writes the received online transaction request into the database first, and when the memory is idle, the online transaction request is obtained from the database for processing. For some online transaction requests, such as online transaction requests for purchasing financial products or online transaction requests for purchasing goods, the online transaction requests should not be denied, and if the application server 31 of the background application system 3 is full and cannot receive new online transaction requests, the online transaction requests can be processed through a database-level asynchronous processing mechanism.
Fig. 2 is a flowchart of an online transaction processing method according to an embodiment of the present invention, and as shown in fig. 2, the online transaction processing method according to an embodiment of the present invention includes:
s201, receiving an online transaction request and writing the online transaction request into a memory queue;
specifically, the foreground terminal of the foreground application system sends an online transaction request to a switching server, and the switching server receives each online transaction request and then writes each online transaction request into a memory queue one by one. Wherein the online transaction request includes, but is not limited to, a financial purchase request, an online banking login request, a balance inquiry request, a transfer request, a payment request, and the like.
S202, acquiring transaction flow parameters based on the online transaction requests in the memory queue;
specifically, after writing the online transaction request into a memory queue, the switching server obtains a transaction flow parameter based on the online transaction request in the memory queue. The transaction flow parameters include, but are not limited to, an average number of online transaction requests, an average transaction amount per unit time, and an average response time, which are set according to actual needs, and the embodiment of the invention is not limited.
And S203, if the transaction flow parameter does not meet the memory-level transaction execution rule, a first switching instruction is sent to the middle-background application system so that the middle-background application system is switched from the memory-level asynchronous processing mechanism to the database-level asynchronous processing mechanism.
Specifically, after obtaining the transaction flow parameter, the switching server determines whether the transaction flow parameter meets a memory level transaction execution rule, and if the transaction flow parameter meets the memory level transaction execution rule, the switching server sends an online transaction request to an application server of the middle-background application system for processing. If the transaction flow parameters do not meet the memory level transaction execution rules, the switching server sends a first switching instruction to the mid-background application system so that the mid-background application system is switched from a memory level asynchronous processing mechanism to a database level asynchronous processing mechanism. The memory level transaction execution rule is preset and set according to actual needs, and the embodiment of the invention is not limited. The first switching instruction is preset and set according to actual needs, and the embodiment of the invention is not limited. The memory level asynchronous processing mechanism and the database level asynchronous processing mechanism are preconfigured to the middle-background application system.
For example, if the transaction flow parameter includes a parameter a, the memory level transaction execution rule includes a memory level transaction execution condition corresponding to the parameter a, and if the parameter a does not satisfy the corresponding memory level transaction execution condition, the transaction flow parameter does not satisfy the memory level transaction execution rule. If the parameter A meets the corresponding memory level transaction execution condition, the transaction flow parameter meets the memory level transaction execution rule.
For example, transaction flow parameters include two parameters: and the memory level transaction execution rule comprises memory level transaction execution conditions corresponding to the parameter B and memory level transaction execution conditions corresponding to the parameter C. If the parameter B does not meet the corresponding memory level transaction execution condition or the parameter C does not meet the corresponding memory level transaction execution condition, the transaction flow parameter does not meet the memory level transaction execution rule. If the parameter B meets the corresponding memory level transaction execution condition and the parameter C meets the corresponding memory level transaction execution condition, the transaction flow parameter meets the memory level transaction execution rule.
For example, transaction flow parameters include three parameters: the memory level transaction execution rule comprises memory level transaction execution conditions corresponding to the parameter D, memory level transaction execution conditions corresponding to the parameter E and memory level transaction execution conditions corresponding to the parameter F. If any one of the parameters D, E and F does not meet the corresponding memory level transaction execution condition, the transaction flow parameter does not meet the memory level transaction execution rule. If the parameters D, E and F meet the corresponding memory-level transaction execution conditions, respectively, the transaction flow parameters meet the memory-level transaction execution rules.
The online transaction processing method provided by the embodiment of the invention can receive the online transaction request and write the online transaction request into the memory queue, acquire the transaction flow parameter based on the online transaction request in the memory queue, and send the first switching instruction to the middle-background application system after the transaction flow parameter does not meet the memory-level transaction execution rule so that the middle-background application system is switched from the memory-level asynchronous processing mechanism to the database-level asynchronous processing mechanism, thereby avoiding the impact of the online transaction request on the middle-background application system during service peaks and ensuring the online transaction processing stability of the middle-background application system.
Fig. 3 is a flow chart of an online transaction processing method according to another embodiment of the present invention, as shown in fig. 3, further, based on the above embodiments, the online transaction processing method according to the embodiment of the present invention further includes:
s301, periodically acquiring transaction flow parameters from a flow record table of a database of the middle background application system;
specifically, after receiving the first switching instruction, the middle-background application system switches to a database-level asynchronous processing mechanism by a memory-level asynchronous processing mechanism, pauses writing an online transaction request into a memory, writes the received online transaction request into a database, waits until a subsequent memory is idle, writes the online transaction request in the database into the memory for processing, obtains a transaction flow parameter based on the online transaction request in the database, and records the transaction flow parameter into a flow record table. And after the switching server sends the first switching instruction, the switching server periodically accesses a database of the middle-background application system to acquire the transaction flow parameters in the flow record table.
S302, if the transaction flow parameters do not meet the database-level transaction execution rules, a second switching instruction is sent to the middle-background application system so that the middle-background application system is switched from a database-level asynchronous processing mechanism to a memory-level asynchronous processing mechanism; wherein the database-level transaction execution rules correspond to the memory-level transaction execution rules.
Specifically, after obtaining the transaction flow parameters in the flow record table, the switching server determines whether the transaction flow parameters meet the database-level transaction execution rules, and if the transaction flow parameters meet the database-level transaction execution rules, the switching server directly sends the online transaction request to the middle-background application system for processing after receiving the online transaction request. If the transaction flow parameters do not meet the database-level transaction execution rules, the switching server sends a second switching instruction to the mid-background application system to cause the mid-background application system to switch from the database-level asynchronous processing mechanism to the memory-level asynchronous processing mechanism. After the background application system is switched to the memory level asynchronous processing mechanism, the online transaction request which is not completed in the database is written into the memory, and the subsequently received online transaction request is not written into the database again but is directly written into the memory. The database-level transaction execution rules are preset and set according to actual needs, and the embodiment of the invention is not limited. The second switching instruction is preset and set according to actual needs, and the embodiment of the invention is not limited. It is appreciated that if the transaction flow parameters satisfy the database-level transaction execution rules, the online transaction request continues to be processed using the database-level asynchronous processing mechanism. The database-level transaction execution rules correspond to the memory-level transaction execution rules to ensure that online transaction requests are processed by either a memory-level asynchronous processing mechanism or a database-level asynchronous processing mechanism.
For example, if the transaction flow parameter includes a parameter G, the database-level transaction execution rule includes a database-level transaction execution condition corresponding to the parameter G, and if the parameter G does not satisfy the corresponding database-level transaction execution condition, the transaction flow parameter does not satisfy the database-level transaction execution rule. If the parameter A meets the corresponding database-level transaction execution condition, the transaction flow parameter meets the database-level transaction execution rule.
For example, transaction flow parameters include two parameters: the database-level transaction execution rule comprises a memory-level transaction execution condition corresponding to the parameter H and a memory-level transaction execution condition corresponding to the parameter I. If the parameter H does not meet the corresponding database-level transaction execution condition or the parameter I does not meet the corresponding database-level transaction execution condition, the transaction flow parameter does not meet the database-level transaction execution rule. If the parameter H meets the corresponding database-level transaction execution condition and the parameter I meets the corresponding database-level transaction execution condition, the transaction flow parameter meets the database-level transaction execution rule.
For example, transaction flow parameters include three parameters: the database-level transaction execution rules comprise database-level transaction execution conditions corresponding to the parameters J, database-level transaction execution conditions corresponding to the parameters K and database-level transaction execution conditions corresponding to the parameters M. If any one of the parameters J, K and M does not meet the corresponding database-level transaction execution conditions, the transaction flow parameters do not meet the database-level transaction execution rules. If the parameters J, K and M meet the corresponding database-level transaction execution conditions, respectively, the transaction flow parameters meet the database-level transaction execution rules.
For example, an application server of the middle-background application system may be used as a scheduling server, where the scheduling server is in communication with the switching servers, and after receiving a second switching instruction sent by the switching server, the scheduling server forwards the second switching instruction to each application server, and after receiving the second switching instruction, the application server stops processing the online transaction request by using the memory-level asynchronous processing mechanism and switches to processing the online transaction request by using the database-level asynchronous processing mechanism. Each application server is preconfigured with a memory-level asynchronous processing mechanism and a database-level asynchronous processing mechanism.
For example, the memory level transaction execution rules include that the average number of online transaction requests is less than or equal to a memory queue threshold, and correspondingly, the database level transaction execution rules include that the average number of online transaction requests is greater than the memory queue threshold. The memory-level transaction execution rules include that the average number of the online transaction requests is smaller than or equal to a memory queue threshold and the transaction amount per unit time of the online transaction requests is smaller than or equal to a transaction amount threshold, and correspondingly, the database-level transaction execution rules include that the average number of the online transaction requests is larger than the memory queue threshold and the transaction amount per unit time of the online transaction requests is larger than the transaction amount threshold.
The online transaction processing method provided by the embodiment of the invention enables the database-level asynchronous processing mechanism of the middle-background application system to be switched to the memory-level asynchronous processing mechanism, and can improve the processing efficiency of online transaction requests.
The online transaction processing method provided by the embodiment of the invention can flexibly switch the middle-background application system between the memory-level asynchronous processing mechanism and the database-level asynchronous processing mechanism, thereby improving the resource utilization rate of the middle-background application system.
Further, based on the above embodiments, the transaction flow parameter includes at least one of an average number of online transaction requests, an amount of transactions per unit time, and an average response time.
Specifically, the transaction flow parameter includes at least one of an average number of online transaction requests, an amount of transaction per unit time, and an average response time, i.e., the transaction flow parameter may include any one of an average number of online transaction requests, an amount of transaction per unit time, and an average response time, the transaction flow parameter may include any two of an average number of online transaction requests, an amount of transaction per unit time, and an average response time, and the transaction flow parameter may include an average number of online transaction requests, an amount of transaction per unit time, and an average response time.
The average number of the online transaction requests is obtained by calculating the average value of the number of the online transaction requests in the memory queue in a first preset time period or the average value of the number of the online transaction requests in the database in a second preset time period. For example, the number of online transaction requests in the memory queue is acquired every N seconds in the first preset time period, and if the number of m online transaction requests is acquired in the first preset time period, the average number of the online transaction requests is the average number of the online transaction requestsWherein Q is i The number of the online transaction requests acquired for the ith time is represented, i is a positive integer and is less than or equal to m. The first preset time period and the second preset time period are set according to actual needs, and the embodiment of the invention is not limited.
The unit time transaction amount of the online transaction request is obtained by calculating the average processing amount of the online transaction request in the memory queue in a third preset time period or the average processing amount of the online transaction request in the database in a fourth preset time period. For example, in the third preset period Δt, x online transaction requests in the memory queue are sent to the middle-background application system for processing, and then the online transaction requests have a transaction amount p per unit time 2 =x/Δt. The third preset time period and the fourth preset time period are set according to actual needs, and the embodiment of the invention is not limited.
The average response time of the online transaction requests is obtained by calculating the average value of the response time of each online transaction request entering and exiting the memory queue in a fifth preset time period, or by calculating the average value of the response time of each online transaction request entering and exiting the memory queue in a sixth preset time periodThe average value of the response time of each online transaction request of the database is obtained. For example, the switch server records that n online transaction requests enter the memory queue and leave the memory queue within a third predetermined period of time, i.e., n online transaction requests are sent to the application server by the switch server, then the average response time of the online transaction requestsWherein t is j Representing response time, t, of a jth online transaction request entering and exiting the memory queue within a fifth preset time period j ＝t j2 -t j1 j，t j2 T is the moment when the j-th online transaction request entering and exiting the memory queue leaves the memory queue j1 And j is a positive integer and is less than or equal to n when the j-th online transaction request entering and exiting the memory queue enters the memory queue. The fifth preset time period is set according to actual needs, and the embodiment of the invention is not limited.
Further, on the basis of the above embodiments, the memory level transaction execution rule includes at least one of a memory level transaction execution condition corresponding to an average number of the online transaction requests, a memory level transaction execution condition corresponding to a unit time transaction amount of the online transaction requests, and a memory level transaction execution condition corresponding to an average response time of the online transaction requests, where:

the memory-level transaction execution condition corresponding to the unit-time transaction amount of the online transaction request is that the unit-time transaction amount of the online transaction request is less than or equal to a transaction amount threshold;
the memory-level transaction execution condition corresponding to the average response time of the online transaction request is that the average response time of the online transaction request is less than or equal to a response time threshold.
Specifically, the memory level transaction execution rule may include at least one of a memory level transaction execution condition corresponding to an average number of online transaction requests, a memory level transaction execution condition corresponding to a unit time transaction amount of the online transaction requests, and a memory level transaction execution condition corresponding to an average response time of the online transaction requests, that is, the transaction flow parameter may include any one of a memory level transaction execution condition corresponding to an average number of the online transaction requests, a memory level transaction execution condition corresponding to a unit time transaction amount of the online transaction requests, and a memory level transaction execution condition corresponding to an average response time of the online transaction requests, and the transaction flow parameter may include any two of a memory level transaction execution condition corresponding to an average number of the online transaction requests, a memory level transaction execution condition corresponding to a unit time transaction amount of the online transaction requests, and a memory level transaction execution condition corresponding to an average response time of the online transaction requests.
The switch server compares the average number of online transaction requests with a memory queue threshold, and if the average number of online transaction requests is greater than the memory queue threshold, it may be determined that the average number of online transaction requests does not satisfy a corresponding memory-level transaction execution condition. If the average number of online transaction requests is less than or equal to the memory queue threshold, then it may be determined that the average number of online transaction requests meets a corresponding memory level transaction execution condition. The memory queue threshold is set according to practical experience, and the embodiment of the invention is not limited.

If the average response time of the online transaction request is less than or equal to the response time threshold, it may be determined that the average response time of the online transaction request meets a corresponding memory-level transaction execution condition. The response time threshold is set according to practical experience, and the embodiment of the invention is not limited.
Further, on the basis of the above embodiments, the database-level transaction execution rule includes at least one of a database-level transaction execution condition corresponding to an average number of the online transaction requests, a database-level transaction execution condition corresponding to a unit-time transaction amount of the online transaction requests, and a database-level transaction execution condition corresponding to an average response time of the online transaction requests, wherein:

Fig. 5 is a schematic structural diagram of an online transaction processing device according to an embodiment of the present invention, and as shown in fig. 5, the online transaction processing device according to an embodiment of the present invention includes a receiving unit 501, an obtaining unit 502, and a first switching unit 503, where:
the receiving unit 501 is configured to receive an online transaction request and write the online transaction request into a memory queue; the obtaining unit 502 is configured to obtain a transaction flow parameter based on the online transaction request in the memory queue; the first switching unit 503 is configured to send a first switching instruction to the mid-background application system after the transaction flow parameter does not meet the memory level transaction execution rule, so that the mid-background application system is switched from the memory level asynchronous processing mechanism to the database level asynchronous processing mechanism.
Specifically, the foreground terminal of the foreground application system sends the online transaction request to the receiving unit 501, and the receiving unit 501 receives each online transaction request and then writes each online transaction request into the memory queue one by one. Wherein the online transaction request includes, but is not limited to, a financial purchase request, an online banking login request, a balance inquiry request, a transfer request, a payment request, and the like.
After writing the online transaction request into the memory queue, the obtaining unit 502 obtains a transaction flow parameter based on the online transaction request in the memory queue. The transaction flow parameters include, but are not limited to, an average number of online transaction requests, an average transaction amount per unit time, and an average response time, which are set according to actual needs, and the embodiment of the invention is not limited.
After obtaining the transaction flow parameter, the first switching unit 503 determines whether the transaction flow parameter meets a memory level transaction execution rule, and if the transaction flow parameter meets the memory level transaction execution rule, the switching server sends an online transaction request to an application server of the middle-background application system for processing. If the transaction flow parameters do not meet the memory level transaction execution rules, the switching server sends a first switching instruction to the mid-background application system so that the mid-background application system is switched from a memory level asynchronous processing mechanism to a database level asynchronous processing mechanism. The memory level transaction execution rule is preset and set according to actual needs, and the embodiment of the invention is not limited. The first switching instruction is preset and set according to actual needs, and the embodiment of the invention is not limited. The memory level asynchronous processing mechanism and the database level asynchronous processing mechanism are preconfigured to the middle-background application system.
The online transaction processing device provided by the embodiment of the invention can receive the online transaction request and write the online transaction request into the memory queue, obtains the transaction flow parameter based on the online transaction request in the memory queue, and sends the first switching instruction to the middle-background application system after the transaction flow parameter does not meet the memory-level transaction execution rule so that the middle-background application system is switched from the memory-level asynchronous processing mechanism to the database-level asynchronous processing mechanism, thereby avoiding the impact of the online transaction request on the middle-background application system during service peaks and ensuring the online transaction processing stability of the middle-background application system.
Fig. 6 is a schematic structural diagram of an online transaction processing device according to another embodiment of the present invention, as shown in fig. 6, further, based on the above embodiments, the online transaction processing device according to the embodiment of the present invention further includes an obtaining unit 504 and a second switching unit 505, where:
the obtaining unit 504 is configured to obtain transaction flow parameters from a flow record table of a database of the background application system periodically; the second switching unit 505 is configured to send a second switching instruction to the middle-background application system after the transaction flow parameter does not meet the database-level transaction execution rule, so that the middle-background application system is switched from the database-level asynchronous processing mechanism to the memory-level asynchronous processing mechanism; wherein the database-level transaction execution rules correspond to the memory-level transaction execution rules.
Specifically, after receiving the first switching instruction, the middle-background application system switches to a database-level asynchronous processing mechanism by a memory-level asynchronous processing mechanism, pauses writing an online transaction request into a memory, writes the received online transaction request into a database, waits until a subsequent memory is idle, writes the online transaction request in the database into the memory for processing, obtains a transaction flow parameter based on the online transaction request in the database, and records the transaction flow parameter into a flow record table. After sending the first switching instruction, the obtaining unit 504 may access the database of the mid-background application system periodically to obtain the transaction flow parameters in the flow record table.
After obtaining the transaction flow parameters in the flow record table, the second switching unit 505 determines whether the transaction flow parameters meet the database-level transaction execution rules, and if the transaction flow parameters meet the database-level transaction execution rules, the switching server directly sends the online transaction request to the middle-background application system for processing after receiving the online transaction request. If the transaction flow parameters do not meet the database-level transaction execution rules, the switching server sends a second switching instruction to the mid-background application system to cause the mid-background application system to switch from the database-level asynchronous processing mechanism to the memory-level asynchronous processing mechanism. After the background application system is switched to the memory level asynchronous processing mechanism, the online transaction request which is not completed in the database is written into the memory, and the subsequently received online transaction request is not written into the database again but is directly written into the memory. The database-level transaction execution rules are preset and set according to actual needs, and the embodiment of the invention is not limited. The second switching instruction is preset and set according to actual needs, and the embodiment of the invention is not limited. It is appreciated that if the transaction flow parameters satisfy the database-level transaction execution rules, the online transaction request continues to be processed using the database-level asynchronous processing mechanism. The database-level transaction execution rules correspond to the memory-level transaction execution rules to ensure that online transaction requests are processed by either a memory-level asynchronous processing mechanism or a database-level asynchronous processing mechanism.
