Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the invention. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the invention. It may be evident, however, that one or more embodiments may be practiced without these specific details. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present invention.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms "comprises," "comprising," and/or the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.
All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It should be noted that the terms used herein should be construed to have meanings consistent with the context of the present specification and should not be construed in an idealized or overly formal manner.
Where expressions like at least one of "A, B and C, etc. are used, the expressions should generally be interpreted in accordance with the meaning as commonly understood by those skilled in the art (e.g.," a system having at least one of A, B and C "shall include, but not be limited to, a system having a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).
In the technical scheme of the invention, the related data (such as including but not limited to personal information of a user) are collected, stored, used, processed, transmitted, provided, disclosed, applied and the like, all meet the requirements of related laws and regulations, necessary security measures are adopted, and the public welcome is not violated.
According to an embodiment of the invention, a Transaction (Transaction) characterizes a program execution unit (unit) that accesses and updates various data items in a database.
According to an embodiment of the invention, a transaction is the basic unit of recovering and concurrency controlling various data items in a database.
According to an embodiment of the invention, a transaction may have 4 attributes: atomicity (atom), consistency (consistency), isolation (isolation), durability (durability). The four attributes are commonly referred to as ACID characteristics.
According to an embodiment of the invention, an atomicity characterizes a transaction as an indivisible unit of work, and operations included in the transaction are either all done or none done, without ending in some intermediate link. If a transaction makes an error during execution, the modification of the data in the database by the transaction is restored to the state before the transaction began, as if the transaction had never been executed.
According to embodiments of the present invention, the integrity of the database is not compromised before and after execution of the transaction. I.e., the transaction changes the database from one coherency state to another. The consistency of the transaction has close association with atomicity.
According to an embodiment of the invention, isolation characterization is that in the case that multiple concurrent transactions read, write and modify their data simultaneously, execution of one of the multiple concurrent transactions cannot be interfered by other transactions. The isolation of the transactions can prevent data inconsistency in the database caused by cross execution of a plurality of transactions when the plurality of transactions are executed concurrently.
According to embodiments of the invention, persistence is also referred to as permanence (permanence). After the persistence characterizing transaction is committed, the transaction's modification to the data in the database is permanent and will not be lost even if the system fails.
According to embodiments of the present invention, in some scenarios, it is ensured that transactions run in a non-transactional manner.
According to an embodiment of the invention, for example: in the case of the transfer of the user A to the user B, the transaction C can realize the transfer operation of the user A to the user B, and the transaction C is operated in a transaction mode so as to ensure that all the transfer operations of the user A to the user B succeed or fail together, and ensure the consistency of the operations of data respectively related to the user A and the user B. After the transaction C is completed, the transaction C calls the transaction D to generate the order number related to the transfer of the user A to the user B, and at the moment, the transaction D needs to run in a non-transaction mode to ensure that the transaction D is not influenced by the transaction C, namely whether the transaction D is successful or not, the transaction D can generate the order number related to the transfer of the user A to the user B, so that the operation of transferring the user A to the user B can be queried according to the order number generated by the transaction D.
In the related art, whether the transaction operates in a non-transaction mode is generally ensured by expanding codes related to the transaction management framework or not and detecting whether the transaction operates in the non-transaction mode.
In order to at least partially solve the technical problems in the related art, the invention provides a method and a device for determining a transaction running mode, electronic equipment and a storage medium, which can be applied to the technical field of computers. The method for determining the transaction operation mode comprises the following steps: setting the propagation attribute value of the transaction to be a first preset value; acquiring a connection attribute value of a database corresponding to the transaction, wherein the connection attribute value characterizes an operation mode adopted by the transaction when processing data in the database, and is configured according to the propagation attribute value; and determining the operation mode of the transaction according to the connection attribute value under the condition that the connection attribute value is equal to the second preset value.

It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely. There may be any number of terminal devices, networks, and servers, as desired for implementation.
The method for determining the transaction operation mode according to the embodiment of the present invention will be described in detail below based on the scenario described in fig. 1 through fig. 2 to 3.
FIG. 2 illustrates a flow chart of a method of determining a transaction run mode according to an embodiment of the invention.
As shown in FIG. 2, the method for determining the transaction operation mode in this embodiment includes operations S210-S230.
In operation S210, a propagation attribute value of a transaction is set to a first preset value.
According to an embodiment of the present invention, the transaction operation modes include a transaction operation mode and a non-transaction operation mode. In the case that the transaction is in the transaction running mode, the multiple program statements included in the transaction are executed successfully together and fail to be executed together. Under the condition that the transaction is in a non-transaction running mode, a plurality of program sentences included in the transaction are not influenced by the execution results.
According to an embodiment of the invention, a propagation attribute corresponding to a propagation attribute value characterizes the propagation behavior when one transaction is nested into another already existing transaction. Thus, after determining the propagation attribute value of a transaction, the propagation behavior of the transaction when nested into another already existing transaction can be determined.
According to an embodiment of the invention, the propagation attribute value of a transaction reflects the way the transaction is running.
According to an embodiment of the invention, for example, there is already a running transaction E, in which case transaction F may be added to transaction E or run alone, depending on the propagation attribute value associated with transaction F.
According to the embodiment of the invention, in the case that the transaction F is added to the transaction E according to the propagation attribute value related to the transaction F, the transaction E and the transaction F as a whole process data in the database, and the transaction E and the transaction F succeed or fail together in operating the data in the database, and the operation mode of the transaction F is a transaction operation mode.
According to the embodiment of the invention, in the case that the transaction F is independently operated according to the propagation attribute value related to the transaction F, the execution results between the transaction E and the transaction F are not influenced, and at this time, the operation mode of the transaction F is a non-transaction operation mode.
According to the embodiment of the invention, the Spring framework is an open-source development platform based on an object-oriented programming language (Java), various types of development tools are integrated into the Spring framework, and durable Java application programs can be quickly developed through the Spring framework.
According to the embodiment of the invention, the propagation attribute value (propagation) of the transaction corresponding to the interface method or the interface class can be set to a first preset value based on the Spring framework in a mode of configuring @ transaction annotation for the interface method or the interface class, and then the operations of opening, submitting or rolling back the transaction and the like according to the @ transaction annotation are managed based on the Spring framework. Wherein @ TransactionAnnotation characterizes annotations used in declarative transaction management programming.
According to the embodiment of the invention, under the spring framework, the propagation attribute value generation of the transaction has seven forms, namely: REQUIRED, SUPPORTS, MANDATORY, REQUIRES _NEW, NOT_ SUPPORTED, NEVER and NESTED.
According to an embodiment of the present invention, for example, a @ transaction (transmission=transmission.required) comment may be configured for an interface method or an interface class based on a spring framework, and a transaction propagation attribute value transmission of a transaction corresponding to the interface method or the interface class may be set to REQUIRED. At this time, before the spring framework starts the transaction, if no other transaction is started, a new transaction is started, so that the transaction operates in a transaction mode. If the transaction is started before other transactions are started, the transaction is added to the other transactions, and the transaction is operated in a transaction mode.
According to an embodiment of the present invention, for example, a @ transaction (transmission=transmission. Not_supported) comment may also be configured for an interface method or an interface class based on a spring framework, and a propagation attribute value transmission of a transaction corresponding to the interface method or the interface class may be set to not_supported. At this time, the spring framework suspends other transactions before starting the transaction, and restarts a new transaction for the transaction if the other transactions have already been started, so that the transaction operates in a non-transactional manner.
According to the embodiment of the invention, the operation mode of the transaction can be simply and quickly managed according to the propagation attribute value based on the spring frame by setting the propagation attribute value of the transaction to the first preset value based on the spring frame.
In operation S220, a connection attribute value of a database corresponding to the transaction is obtained, where the connection attribute value characterizes an operation mode adopted by the transaction when processing data in the database, and the connection attribute value is configured according to the propagation attribute value.
According to the embodiment of the invention, since the engineering environment, configuration, etc. of the independent development component related to the interface method or the interface class affect the operation mode of the transaction corresponding to the interface method or the interface method, even if the interface method or the interface class in the independent development component is configured with the @ transaction=provision. Not_supported annotation, the transaction corresponding to the interface method or the interface class may not be finally operated in a non-transaction mode, that is, the @ transaction annotation is not effective, therefore, the operation mode of the transaction needs to be further detected, and the operation mode of the transaction needs to be further determined.
According to the embodiment of the invention, after the @ transaction annotation is configured for the interface method or the interface class based on the spring framework, before the transaction corresponding to the interface method or the interface class is executed, the spring framework configures the connection attribute value of the database corresponding to the transaction according to the @ transaction annotation, so that the running mode of the transaction can be further determined by detecting the connection attribute value of the database related to the transaction.
According to an embodiment of the invention, the object-relationship-based mapping framework MyBatis is a data persistence layer framework that supports custom SQL, storage procedures, and advanced mapping. MyBatis avoids almost all JDBC code, manual setting of parameters, and the effort to get a result set. MyBatis can use simple XML or annotations to configure and map the original type, interface, and Java entity class (Plain Ordinary Java Object, POJOs, plain Java object) to records in the database.
According to embodiments of the invention, data in an operation database related to transactions may be operated on using a spring-based MyBatis framework.
According to the embodiment of the invention, the connection attribute value of the database stored at the database end can be obtained by using the spring-based MyBatis framework, and then the running mode of the transaction can be further determined according to the connection attribute value.
In operation S230, in case the connection attribute value is equal to the second preset value, the operation mode of the transaction is determined according to the connection attribute value.
According to an embodiment of the present invention, the connection attribute value may include, for example, both true and false forms. In the case where the connection attribute value is true, the transaction may run in a non-transactional manner. In the case where the connection attribute value is false, the transaction may run in a transactional manner. And under the condition that the second preset value is true and the connection attribute value is detected to be equal to true, determining that the transaction runs in a non-transaction mode. In the case where the second preset value is false, and it is detected that the connection attribute value is equal to false, it may be determined that the transaction is running in a transactional manner.
According to the embodiment of the invention, the method for determining the transaction operation mode can indirectly determine whether the transaction is operated in a non-transaction mode by determining whether the connection attribute value of the database corresponding to the transaction is equal to the second preset value, thereby ensuring the accuracy of determining the operation mode of the transaction, and avoiding the generation of new defect problems and compatibility problems without increasing and expanding codes related to a transaction management framework.
According to an embodiment of the present invention, before acquiring a connection attribute value of a database corresponding to a transaction, the method includes:
the connection attribute values are configured according to the propagation attribute values.
According to the embodiment of the invention, the spring framework can be utilized to configure the connection attribute value of the database related to the transaction according to the propagation attribute value set by the @ transaction annotation, the connection attribute value is sent to the server side of the database related to the transaction, and the server side stores the connection attribute value.
According to the embodiment of the invention, the spring framework is utilized to configure the connection attribute value of the database related to the transaction according to the propagation attribute value set by the @ transaction annotation, so that the efficiency of configuring the connection attribute value according to the propagation attribute value is improved.
According to the embodiment of the invention, under the condition that the @ transitional annotation related to the propagation attribute value is effective under the spring framework, the connection attribute value is configured according to the propagation attribute value, so that the operation modes of the transaction reflected according to the propagation attribute value and the connection attribute value can be ensured to be the same, and the operation modes of the transaction can be accurately determined according to the connection attribute value.
According to the embodiment of the invention, under the condition that @ transitional annotation related to the propagation attribute value is not effective under the spring framework, the connection attribute value is configured according to the propagation attribute value, the operation modes of the transaction reflected according to the propagation attribute value and the connection attribute value are different, and further, the operation modes of the transaction can be accurately determined to be incorrect according to the connection attribute value.
According to an embodiment of the present invention, for operation S220, obtaining the connection attribute value of the database corresponding to the transaction may further include the following operations:
acquiring a session object related to a transaction, wherein the session object comprises a database connection object, and the database connection object comprises a method for operating a database; acquiring a database connection object according to the session object;
and obtaining a connection attribute value according to the database connection object.
According to the embodiment of the invention, a session object related to the transaction can be acquired by using a spring-based MyBatis framework, and then the object is connected according to a database to obtain a connection attribute value.
According to the embodiment of the invention, the connection attribute value can be obtained according to the code sqlSessionFacto.openSession (). GetConnection (). GetAutoCommit () based on the spring MyBatis framework.
According to the embodiment of the invention, the session object related to the transaction is firstly obtained by utilizing the spring-based MyBatis frame, and then the connection attribute value is obtained according to the database connection object, so that the connection attribute value is efficiently and quickly obtained.
According to an embodiment of the invention, a session object related to a transaction is acquired, wherein the session object comprises a database connection object, and the database connection object comprises a method for operating a database; acquiring a database connection object according to the session object; and obtaining a connection attribute value according to the database connection object, and preparing for determining the operation mode of the transaction according to the connection attribute value.
According to an embodiment of the invention, the connection attribute value comprises an auto-commit attribute value.
According to the embodiment of the invention, the database defaults to a transaction automatic commit mode, namely, the automatic commit attribute value is 1 (or true), at this time, each code statement in the transaction is automatically executed as a single transaction, and the operation mode of the transaction is a non-transaction operation mode. In the case where the automatic commit mode of the database needs to be turned off to ensure consistency of the processed data in the database, the automatic commit mode of the database needs to be reset, i.e., the automatic commit attribute value is 0 (or false).
According to the embodiment of the invention, the automatic submission attribute value reflects the operation mode of the transaction, so that the operation mode of the transaction can be further accurately determined according to the automatic submission attribute value.
According to an embodiment of the present invention, the method for determining a transaction running mode further includes:
detecting a call link related to the transaction under the condition that the connection attribute value is not equal to the second preset value, so as to obtain a first detection result;
and reconfiguring the connection attribute value according to the first detection result.
According to the embodiment of the invention, under the condition that the connection attribute value is not equal to the second preset value, the @ transmission annotation related to the propagation attribute value is not effective under the spring framework, and the running mode of the transaction is incorrect.
According to the embodiment of the invention, the first detection result is obtained by detecting the call link related to the transaction, the connection attribute value is reconfigured according to the first detection result, and the purpose of quickly reading and positioning the defect on the call link related to the transaction according to the first detection result is achieved, so that the connection attribute value is reconfigured after the defect of the call link related to the transaction is quickly corrected, and the transaction operation mode corresponding to the connection attribute value is quickly obtained.

Step 340 further includes step 341, before executing the transaction corresponding to the embedded method M, the determining method of the transaction running mode according to the embodiment of the present invention detects an auto-commit attribute value of the database corresponding to the transaction, and determines whether the transaction corresponding to the embedded method M runs in a non-transaction mode.
In step 340, in the case where it is determined that the transaction corresponding to the embedded method M is running in a non-transactional manner, the data in the database corresponding to the transaction is processed with the transaction corresponding to the embedded method.
In step 350, the execution of the transaction corresponding to the embedded method M is ended, the transaction corresponding to the embedded method M is submitted, and the transaction corresponding to the method N is restored.
In step 360, the transaction corresponding to method N continues to be executed, and the data in the database corresponding to the transaction is processed using the transaction corresponding to method N.
At step 370, the transaction corresponding to method N is committed and execution of the transaction corresponding to method N ends.
As shown in fig. 3, before executing the transaction corresponding to the embedded method M, by detecting the automatic commit attribute value of the database corresponding to the transaction, the operation mode of the transaction corresponding to the embedded method M is further ensured, and the accuracy of the operation mode of the transaction corresponding to the embedded method M is ensured.
