Java远程调用原理DEMO

1.　　POJO

public class DemoInfo implements Serializable{

    private String name;

    private int age;

    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;
    }

    @Override
    public String toString() {
        return "DemoInfo{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

2.　　Service接口定义

public interface IDemoService {

    DemoInfo getDemoInfoById(DemoInfo info);

}

3.　　Provider服务实现

public class DemoServiceImpl implements IDemoService{
    @Override
    public DemoInfo getDemoInfoById(DemoInfo info) {
        System.out.println(info);
        DemoInfo demoInfo = new DemoInfo();
        demoInfo.setName("zhangsan");
        demoInfo.setAge(20);
        return demoInfo;
    }
}

4.　　Provider

public class Provider {

    public static void main(String[] args) {
        ServerSocket server = null;
        try {
            server = new ServerSocket(5678);
            while (true) {
                Socket socket = server.accept();
                ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
                DemoInfo info = (DemoInfo) ois.readObject();
                socket.shutdownInput();
                IDemoService service = new DemoServiceImpl();
                DemoInfo retInfo = service.getDemoInfoById(info);
                ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream());
                oos.writeObject(retInfo);
                oos.flush();
                socket.shutdownOutput();
                socket.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } finally {
            try {
                if (server != null) {
                    server.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

    }

}

5.　　Consumer

public class Consumer {

    public static void main(String[] args) {
        IDemoService service = (IDemoService) Proxy.newProxyInstance(IDemoService.class.getClassLoader(), new Class[]{IDemoService.class}, new InvocationHandler() {
            @Override
            public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
                Socket socket = new Socket("192.168.1.1",5678);
                ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream());
                oos.writeObject(args[0]);
                oos.flush();
                socket.shutdownOutput();
                ObjectInputStream ios = new ObjectInputStream(socket.getInputStream());
                DemoInfo retInfo = (DemoInfo)ios.readObject();
                socket.shutdownInput();
                System.out.println(retInfo);
                return null;
            }
        });
        DemoInfo info = new DemoInfo();
        info.setName("lisi");
        info.setAge(18);
        service.getDemoInfoById(info);
    }

}
