Multi Transaction Manager Spring Configuration with Annotations - spring

Question

There are two bean JpaTransactionManager.
Can Manage them with Qualifier notation.
<bean id="transactionManagerConstant" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="constant"/>
<qualifier value="first"/>
</bean>
<bean id="transactionManagerRelative" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="relative"/>
<qualifier value="second"/>
</bean>
Java code:
#Transactional("first")
public String saveWork(){
em1.persist(work);
work = (Work) ctx.getBean("work");
return "/workLists.xhtml";
}
#Transactional("second")
public String saveEvent(){
em2.persist(event);
event = (Event) ctx.getBean("event");
return "/eventLists.xhtml";
}
The problem is: how do I use the level of isolation or readOnly assignment? #Qualifier annotations does not work:
#Transactional(isolation = Isolation.SERIALIZABLE, propagation=Propagation.REQUIRED, readOnly = false)
#Qualifier("first")
public String saveWork(){
em1.persist(work);
work = (Work) ctx.getBean("work");
return "/workLists.xhtml";
}
#Transactional(isolation = Isolation.SERIALIZABLE, propagation=Propagation.REQUIRED, readOnly = false)
#Qualifier("second")
public String saveEvent(){
em2.persist(event);
event = (Event) ctx.getBean("event");
return "/eventLists.xhtml";
}
How can I solve this problem?

Answer 1

You should be putting the #Qualifier annotation on the member that is the TransactionManager, not on the method that uses it.
The following assumes that em1 and em2 are the TransactionManager's defined in the spring configuration above.
#Autowired
#Qualifier("first")
private TransactionManager em1;
#Autowired
#Qualifier("second")
private TransactionManager em2;
#Transactional(isolation = Isolation.SERIALIZABLE, propagation=Propagation.REQUIRED, readOnly = false)
public String saveWork(){
em1.persist(work);
work = (Work) ctx.getBean("work");
return "/workLists.xhtml";
}
#Transactional(isolation = Isolation.SERIALIZABLE, propagation=Propagation.REQUIRED, readOnly = false)
public String saveEvent(){
em2.persist(event);
event = (Event) ctx.getBean("event");
return "/eventLists.xhtml";
}
