Problem with @Interceptors on generic bean methods, JBAS7
Hello all,
Migrating my application from JBoss 4.2.3-GA to JBoss 7.1.1-Final I stumpled upon following issue.
What is working fine for me with JB-4.2.3 does not with JB-7.1.1.
I want an interceptor be triggered on a stateless session bean method that is an implementation of a generic superinterface method declaration.
@Stateless
@Remote(TestBeanService.class)
public class TestBean implements TestBeanService {
@Interceptors(TestInterceptor.class)
public void simpleFoo() {
System.out.println("doing simple foo");
}
@Override
@Interceptors(TestInterceptor.class)
public void genericFoo(SomeClass entity) {
System.out.println("doing generic foo");
}
}
//====================================================
public interface TestBeanService extends GenericService<SomeClass> {
public void simpleFoo();
}
//====================================================
public interface GenericService<T> {
public void genericFoo(T entity);
}
//====================================================
public class TestInterceptor {
@AroundInvoke
public Object intercept(InvocationContext invocation) throws Exception {
try {
System.out.println("intercepting method invocation: " + invocation.getMethod());
Object object = invocation.proceed();
return object;
} catch (Exception e) {
e.printStackTrace();
}
}
}
If the genericFoo() method is called from a client the invocation is not being intercepted on JB-7.1.1 (on JB-4.2.3 it is). The simpleFoo() method invocation is intercepted without problems.
The only way I found making genericFoo() be intercepted on JB-7.1.1 is either to declare the @Interceptors(TestInterceptor.class) annotation on top of the bean class (on the cost of making every method in the bean class be intercepted):
@Stateless
@Remote(TestBeanService.class)
@Interceptors(TestInterceptor.class)
public class TestBean implements TestBeanService {
//...
}
The other way around is to add an extra genericFoo() method declaration in the TestBeanService interface, what I was expecting should be unnecessary:
public interface TestBeanService extends GenericService<SomeClass> {
public void simpleFoo();
public void genericFoo(SomeClass entity);
}
Don't know, is this an known/new issue with JBoss (EJB) or am I missing something?
