【获取字段上的注解并进行动态修改值】

1. 获取字段上的注解

aClass 为注解类对应的类
Sensitive 为要获取的注解

Field field = aClass.getDeclaredField(string);
Sensitive sensitive = field.getAnnotation(Sensitive.class);

2.修改注解的值

InvocationHandler invocationHandler = Proxy.getInvocationHandler(sensitive);
Field hField =  invocationHandler.getClass().getDeclaredField("memberValues");
     Field.setAccessible(true);
Map memberValues = (Map) hField.get(invocationHandler);
     memberValues.put("flag", false);
