动态代理 动态修改注解上的参数

动态代理

AOP切面代码

被代理对象
 Object target = joinPoint.getTarget();
当前对象
Object aThis = joinPoint.getThis();
这里拿到的方法和反射的方法获取的不是一样的
 Method method = ((MethodSignature) joinPoint.getSignature()).getMethod();

  Method method1 = null;
        try {
            method1 = target.getClass().getMethod(method.getName(), method.getParameterTypes());
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }
