@Transactional on subclass

[spgmx]

Hi,

I have a subclass of an abstract class which is called by a TaskExecutor. It seems that then something goes wrong with @Transactional.

public interface IFoo
public abstract class AbstractFoo implements IFoo
public class Foo extends AbstractFoo

I have to annotate the abstract class with @Transactional, not the concrete subclass, otherwise no tx is created.

So this works:

@Transactional
public abstract class AbstractFoo implements IFoo


But this not:

@Transactional
public class Foo implements IFoo

I'm using:

<aop:config proxy-target-class="true">
<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>

What is wrong here?

Thank you

Although you are programming against interfaces you have chosen to configure:
<aop:config proxy-target-class="true">

Why?
This causes spring to use CGLIB, in order to create the transactional proxies to your classes. This apporach could lead to problems, if the class is final or some methods are declared final.
Why? Because with CGLIB subclasses of the classes to be proxied are generated, and as we know: it is impossible to override final methods or subclass final classes. (Also CGLIB proxied classes have to have a no-.arg constructor. And you should not access instance variables directly in this case)

Try using dynamic proxies.
The dynamic proxy just implements your bean interface and all should be working.
You only need:
<tx:annotation-driven />

and you might need as well:

<context:component-scan base-package="foo*" />
<context:annotation-config />
