参考java api：

如果参与hascode计算的成员变量中途发生变化，则后面remove时失败，造成内存泄露

### 动态代理的工作原理

代理类创建时需要传入一个InvocationHandler对象，client调用代理类，代理类的相应方法调用InvocationHandler的的invoke方法，InvocationHandler的的invoke方法(可在其中加入日志记录、时间统计等附加功能)再找目标类的相应方法。

### 面向切面编程

把切面的代码以**对象**的形式传递给InvocationHandler的的invoke方法，invoke方法中执行该对象的方法就执行了切面的代码。

所以需要传递两个参数：
