Java实现动态代理的两种方式

public interface People {
    public void sayHello();
}

public class Chinese implements People {

    @Override
    public void sayHello() {
        System.out.println("Chinese say hello.");
    }
}

import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;

public class PeopleInvocationHandler implements InvocationHandler{
    
    private Object peolple;
    
    Intermediary(Object people){
        this.people = people;
    }
    @Override
    public Object invoke(Object proxy, Method method, Object[] args)
            throws Throwable {

        Object invoke = method.invoke(people, args);

import java.lang.reflect.Proxy;

public class Test {
    public static void main(String[] args) {
        People chinese = new People();
        PeopleInvocationHandler invocationHandler = new PeopleInvocationHandler(chinese);
        People proxy = (People) Proxy.newProxyInstance(chinese.getClass().getClassLoader(), chinese.getClass().getInterfaces(), invocationHandler);
        proxy.sayHello();
    }
}

public class Chinese {

        System.out.println("Chinese say hello");
    }
