java - spring aop - 链接多个方面

Question

我有两个方面，一个用于获取锁定 @Around 调用，另一个用于消除方法调用的抖动。这些方面看起来像这样:

@Pointcut("execution(public * * (..))")  
private void anyPublicMethod() {}

@Around("anyPublicMethod() && @annotation(lock)")
public Object all(ProceedingJoinPoint proceedingJoinPoint, Lock lock) throws Throwable {
   // acquire lock, then proceed()
}

另一个看起来像这样:

@Pointcut("execution(public * * (..))")  
private void anyPublicMethod() {}

@Around("anyPublicMethod() && @annotation(debounce)")
public Object all(ProceedingJoinPoint proceedingJoinPoint, Debounce debounce) throws Throwable {
    // debouncing as described in 
    // http://stackoverflow.com/questions/4742210/implementing-debounce-in-java

}

完整代码:

和

https://github.com/rmalchow/lock-aspect/blob/master/src/main/java/com/skjlls/aspects/lock/impl/LockAspect.java

当我将我的@Debounce 和我的@Lock 都放在一个方法上时，我得到了这个异常:

Required to bind 2 arguments, but only bound 1 (JoinPointMatch was NOT bound in invocation)
    at org.springframework.aop.aspectj.AbstractAspectJAdvice.argBinding(AbstractAspectJAdvice.java:584)
    at org.springframework.aop.aspectj.AbstractAspectJAdvice.invokeAdviceMethod(AbstractAspectJAdvice.java:610)
    at org.springframework.aop.aspectj.AspectJAroundAdvice.invoke(AspectJAroundAdvice.java:68)

    at org.springframework.aop.aspectj.MethodInvocationProceedingJoinPoint.proceed(MethodInvocationProceedingJoinPoint.java:85)

这似乎与spring aop not being able to figure out the next thing to call in line有关是另一个方面，而不是实际目标，我已经看到了spring aop 2和3的其他报告......但我正在使用:

spring 4.1.1.RELEASE

Answer 1

对不起我的英语不好。您订购了 Aspect Class 吗？如果你不这样做，这个问题可能会发生

你可以试试这个，例如:

@Aspect
@Order(1)
public class FirstAspect(){}

@Aspect
@Order(2)
public class SecondAspect(){}

值越小，优先级越高
