Question

我有两个方面，一个用于获取锁定@Around一个呼叫，另一个用于去除方法调用。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：

https://github.com/rmalchow/debouncer-aspect/blob/master/src/main/java/com/skjlls/aspects/debounce/impl/DebounceAspect.java

和

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

当我将@Debounce和@Lock放在一个方法上时，我得到了这个例外：

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.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:168)
    at org.springframework.aop.aspectj.MethodInvocationProceedingJoinPoint.proceed(MethodInvocationProceedingJoinPoint.java:85)

它似乎与spring aop有关无法弄清楚下一个要排队的事情是另一个方面，而不是实际的目标，而且我已经看到了来自Spring aop 2和3的其他报告...但是我我正在使用：

spring 4.1.1.RELEASE

对不起，我英语不好。您是否订购了方面类？如果没有，可能会发生此问题

您可以尝试以下操作：

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

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

值越低，优先级越高

spring aop - 链接多个方面
