[英]Spring aspectj annotation pointcut
I was trying to create an Aspectj pointcut on method annotation but I failed all the time with different approaches. 我试图在方法注释上创建一个Aspectj切入点,但我总是以不同的方法失败。 I'm using aspectj autoproxy (I have no other weaving configured in my spring context). 我正在使用aspectj autoproxy(我没有在我的spring上下文中配置其他编织)。 My classes look like this: 我的课程看起来像这样:
public interface Intf
{
@SomeAnnotation
void method1() throws SomeExc;
}
public class Impl implements Intf
{
@Override
public void method1() throws SomeExc
{
//...
}
}
@Aspect
public class MyAspect
{
@AfterThrowing(
pointcut = "execution(* *(..)) && @annotation(SomeAnnotation)",
throwing = "error")
public void afterThrowing(JoinPoint jp, Throwable error)
{
System.err.println(error.getMessage());
}
}
@Component
public class Usage
{
@Autowired
Intf intf;
public void doStuff()
{
intf.method1();
}
}
So I'm wondering why the aspectj won't create the pointcut. 所以我想知道为什么aspectj不会创建切入点。 I managed to make it work using execution(* *(..) throws SomeExc)
which does the job for me but I still want to know what I did wrong. 我设法让它工作使用execution(* *(..) throws SomeExc)
为我做的工作,但我仍然想知道我做错了什么。
Also since method1
is defined in an interface and I specify the annotation on implementing class, is there a way to make it work this way? 此外,由于method1
是在接口中定义的,并且我在实现类上指定了注释,有没有办法让它以这种方式工作? Other proxying mechanisms like transaction management/security works this way in other parts of spring right? 其他代理机制,如事务管理/安全性在弹簧的其他部分以这种方式工作吗? And if I'm using interface proxying would specifying the pointcut on implementing class create the pointcut? 如果我使用接口代理将指定实现类的切入点创建切入点? (I guess not since I'm not using cglib) (我猜不是因为我没有使用cglib)
