实体类PersonEntity

package net.cs30.rmi;

import java.io.Serializable;

/**
 * Created by caochenghua on 2017/4/4.
 */
public class PersonEntity implements Serializable {
    private int id;
    private String name;
    private int age;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

　　服务接口PersonService

package net.cs30.rmi;

import java.rmi.Remote;
import java.rmi.RemoteException;
import java.util.List;

/**
 * Created by caochenghua on 2017/4/4.
 */
public interface PersonService extends Remote {
    public List<PersonEntity> GetList() throws RemoteException;
}

　　服务接口实现PersonServiceImpl

package net.cs30.rmi;

import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
import java.util.LinkedList;
import java.util.List;

/**
 * Created by caochenghua on 2017/4/4.
 */
public class PersonServiceImpl extends UnicastRemoteObject implements PersonService {
    protected PersonServiceImpl() throws RemoteException {
        super();
    }

    @Override
    public List<PersonEntity> GetList() throws RemoteException {
        System.out.println("Get Person Start!");
        List<PersonEntity> personEntityList=new LinkedList<>();
        PersonEntity personEntity=new PersonEntity();
        personEntity.setAge(10);
        personEntity.setId(0);
        personEntity.setName("cao");
        personEntityList.add(personEntity);

        PersonEntity personEntity2=new PersonEntity();
        personEntity2.setAge(10);
        personEntity2.setId(123);
        personEntity2.setName("horizon");
        personEntityList.add(personEntity2);

        return personEntityList;
    }
}

　　服务器端测试代码Program

package net.cs30.rmi;

import java.rmi.Naming;
import java.rmi.registry.LocateRegistry;

/**
 * Created by caochenghua on 2017/4/4.
 */
public class Program {
    public static void main(String[] args) {
        try {
            PersonService personService=new PersonServiceImpl();
            //注册通讯端口
            LocateRegistry.createRegistry(6600);
            //注册通讯路径
            Naming.rebind("rmi://127.0.0.1:6600/PersonService",personService);
            System.out.println("Service Start!");
        }catch (Exception e){
            e.printStackTrace();
        }
    }
}

　　客户端测试代码ProgramClient

package net.cs30.rmi;

import java.rmi.Naming;
import java.util.List;

/**
 * Created by caochenghua on 2017/4/4.
 */
public class ProgramClient {
    public static void main(String[] args) {
        try {
            PersonService personService=(PersonService) Naming.lookup("rmi://127.0.0.1:6600/PersonService");
            List<PersonEntity> personEntityList=personService.GetList();
            for (PersonEntity personEntity:personEntityList){
                System.out.println("ID:"+personEntity.getId()+" Age:"+personEntity.getAge()+" Name:"+personEntity.getName());
            }
        }catch (Exception e){
            e.printStackTrace();
        }
    }
}
