Spring with multiple transaction managers

Spring with multiple transaction managers

Here is repost of http://stackoverflow.com/questions/4423125/spring-is-it-possible-to-use-multiple-transaction-managers-in-the-same-applica question.

Here is applicationContext.xml config part:

view plain copy to clipboard print ?

1. <code><bean id="transactionManager1" class="org.springframework.orm.jpa.JpaTransactionManager">   
2.   <property name="entityManagerFactory" ref="entityManagerFactory1" />   
3.   <qualifier value="account"/>   
4. </bean>  
5.   
6. <bean id="transactionManager2" class="org.springframework.orm.jpa.JpaTransactionManager">  
7.   <property name="entityManagerFactory" ref="entityManagerFactory2" />   
8.   <qualifier value="businessData"/>   
9. </bean></code>  

and code using:

view plain copy to clipboard print ?

1. public class TransactionalService {  
2.   
3.     @Transactional("account")  
4.     public void setSomethingInAccount() { ... }  
5.   
6.     @Transactional("businessData")  
7.     public void doSomethingInBusinessData() { ... }  
8. }  

So, as you see we can simply use several connections with transaction management in Spring application.
