Spring JPA transaction management

Spring JPA transaction management involves configuring the JpaTransactionManager to handle database transactions for Java Persistence API (JPA) entities within a Spring application^[600-developer__java__application-server__weblogic__weblogic-spring-jpa.md].

Configuration

The core component for managing transactions is the JpaTransactionManager bean.^[600-developer__java__application-server__weblogic__weblogic-spring-jpa.md] This manager requires a reference to the EntityManagerFactory to function.^[600-developer__java__application-server__weblogic__weblogic-spring-jpa.md]

XML Configuration

In Spring XML configuration, the transaction manager is defined as follows:

<bean id="transactionManager"
      class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory"></property>
</bean>

To enable support for @Transactional annotations, the <tx:annotation-driven> element must be configured with a reference to the transaction manager^[600-developer__java__application-server__weblogic__weblogic-spring-jpa.md]:

<tx:annotation-driven transaction-manager="transactionManager"/>

Java Configuration

Alternatively, the transaction manager can be configured using Java configuration by defining a @Bean method for JpaTransactionManager and injecting the EntityManagerFactory^[600-developer__java__application-server__weblogic__weblogic-spring-jpa.md]:

@Bean
public JpaTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
    JpaTransactionManager transactionManager = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(entityManagerFactory);
    return transactionManager;
}

Usage

Once configured, transactions can be managed declaratively using the @Transactional annotation on service methods or test classes^[600-developer__java__application-server__weblogic__weblogic-spring-jpa.md]. This allows the framework to handle boundaries such as beginning, committing, or rolling back transactions based on exceptions or specific configurations.
