In a spring bean is it possible to have a shutdown method which can use transactions?
In the destroy method of a spring bean I want to execute some queries to clean up some stuff in the database. Spring doesn't seem to allow this by any means I can find.
The error is always something like:
Invocation of destroy method failed on bean with name 'someBean': org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'transactionManager': Singleton bean creation not allowed while the singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)
The following will tell spring to call shutdownDestroy after the bean is no longer needed. But, I get the above error when trying to use transactions.
<bean id="someId" name="someName" class="someClass"
destroy-method="shutdownDestroy"/>
The same is true when I enable common lifecycle annotations using:
<bean class="org.springframework. ... .CommonAnnotationBeanPostProcessor"/>
and then mark the method with @PreDestroy. That method can't use transactions either.
Is there any way to do this?
EDIT: Thanks! I had the bean implement SmartLifecycle and adding the following and it works very nicely.
private boolean isRunning = false;
@Override
public boolean isAutoStartup() {return true;}
@Override
public boolean isRunning() {return isRunning;}
/** Run as early as possible so the shutdown method can still use transactions. */
@Override
public int getPhase() {return Integer.MIN_VALUE;}
@Override
public void start() {isRunning = true;}
@Override
public void stop(Runnable callback) {
shutdownDestroy();
isRunning = false;
callback.run();
}
@Override
public void stop() {
shutdownDestroy();
isRunning = false;
}
Answer
Interesting Question. I'd say you should be able to do it by letting your bean implement SmartLifeCycle.
That way, if your int getPhase(); method returns Integer.MAX_VALUE, it will be among the first to be called when the ApplicationContext finally shuts down.
