在MethodInterceptor中获取目标

Question

如何在拦截器中获取Target对象？

   bindInterceptor(subclassesOf(A.class), any(), new MethodInterceptor() {
        @Override
        public Object invoke(MethodInvocation methodInvocation) throws Throwable {
            A a = getTarget();    //how?
            return methodInvocation.proceed();
        }
    });

UPD 实际上，有基于反射的解决方案，但它希望有其他解决方案..

private static Object getTarget(MethodInvocation methodInvocation) throws NoSuchFieldException, IllegalAccessException {
    return getFieldValue(methodInvocation, "proxy");
}

private static Object getFieldValue(Object obj, String field) throws NoSuchFieldException, IllegalAccessException {
    Field f = obj.getClass().getDeclaredField(field);
    f.setAccessible(true);
    return f.get(obj);
}

Answer 1

不只是methodInvocation.getThis()吗？
