Hi,
I have an annotation:
@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface Audit
{
String operate() default "";
String desc() default "";
int type();
int idParamIndex() default 0;
}
I put on some methods of my DAO services and advised them in AppModule:
DAOInterface:
@Audit(type=1)
public void delete(int id) throws Exception;
AppModule:
for (Method m : receiver.getInterface().getMethods())
{
if (m.getAnnotation(Audit.class) != null)
{
System.out.println("advising "+m.getName());
receiver.adviseMethod(m, advice);
}
}
There is no problem and I can see the methods are advised by the
System.out above. But in the advise method, I can not get the Audit
annotation:
public void advise(MethodInvocation invocation)
{
String methodName = invocation.getMethod().getName();
Audit audit = invocation.getAnnotation(Audit.class);
System.out.println("method="+methodName+", audit="+audit);
invocation.proceed();
}
The above advise method is called and I can see the system.out is always
like this: "method=delete, audit=null". I need some information in the
Audit annotation but why I can not get the annotation instance?
