动态代理基础

动态代理是在程序运行时动态创建一个代理类，实现的过程和静态代理一致，只是它是由反射实现的， 是AOP的基础

动态代理类不会继承被代理类的接口，而是实现InvocationHandler ，例如:

class OwnerInvocationHandler implements InvocationHandler {
    private PersonBean personBean;

    OwnerInvocationHandler(PersonBean personBean){
        this.personBean = personBean;
    }

    @Override
    public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
        try{
            if(method.getName().startsWith("get")){
                return method.invoke(personBean,args);
            }else if(method.getName().equals("setHotOrNotRating")){
                throw new IllegalAccessException();
            }else if(method.getName().startsWith("set")){
                return method.invoke(personBean,args);
            }
        }catch (InvalidParameterException e){
            e.printStackTrace();
        }
        return null;
    }
}

我们关注的就只是invoke方法和被传入的被代理对象personBean

资料：

Cmder

官网地址: http://cmder.net/
cmder有两个版本，mini版和full版
mini版本，就几M大小，这个也就用来替代windows的cmd
full版本比较大，100多M，模拟了一些常用linux命令（比如ls、cat、more、cp、mv、rm、find、grep等），自带git,而且自带vim。（如果已经安装了git for windows可以只使用mini版，但是要把git的src/bin添加到path中去）
