从 ProceedingJoinPoint 获取 java.lang.reflect.Method？

问题很简短：有没有办法从aspectj ProceedingJoinPoint 获取Method 对象？

目前我正在做

Class[] parameterTypes = new Class[joinPoint.getArgs().length];
Object[] args = joinPoint.getArgs();
for(int i=0; i<args.length; i++) {
    if(args[i] != null) {
        parameterTypes[i] = args[i].getClass();
    }
    else {
        parameterTypes[i] = null;
    }
}

String methodName = joinPoint.getSignature().getName();
Method method = joinPoint.getSignature()
    .getDeclaringType().getMethod(methodName, parameterTypes);

但我不认为这是要走的路......

你的方法没有错，但是还有更好的方法。你必须投射到MethodSignature http://www.eclipse.org/aspectj/doc/released/runtime-api/org/aspectj/lang/reflect/MethodSignature.html

MethodSignature signature = (MethodSignature) joinPoint.getSignature();
Method method = signature.getMethod();
