Spring transaction

　　 First of all we know that In fact, Spring does not directly manage transactions, butprovides a variety of transaction managers< strong>. They delegate the responsibility of transaction management to the transaction of the relevant platform framework provided by persistence mechanisms such as Hibernate or JTA.

　　Spring’s transaction is mainly divided into: programmatic transaction, declarative transaction

　　第The transaction manager must be configured in one step (the dataSource is the transaction source)

"transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

　　"dataSource" ref="dataSource" />

　　 The configuration we use for programmatic transactions:

 1: Programmatic transaction management



 "transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate">

 　　"transactionManager" ref="transactionManager">

　　 

　　"isolationLevelName" value="ISOLATION_DEFAULT">

　　"propagationBehaviorName" value="PROPAGATION_REQUIRED">

　　My common configuration for declarative transactions is as follows:

　　 first share with you The declarative transactions summarized below have the following methods

　　　　1, use bean proxy (one proxy per bean)

　　　　2 Use bean proxy (multiple beans, one proxy)

　　　 3, use interceptor

　　　　4, use tx tag

2: Declarative transaction management: one is tx, the other is based on @Transactional annotations

"advice" transaction-manager="transactionManager">
　　  
　　　　"insert" propagation= "REQUIRED" read-only="false" rollback-for="Exception"/> 
　　 
 

"transactionManager" />
