volatile的工作机制代码测试之socket学习笔记

服务端：

package cn.itcast.bigdata.socket;import java.net.InetSocketAddress;import java.net.ServerSocket;import java.net.Socket;public class ServiceServer {    public static void main(String[] args) throws Exception {        // 创建一个serversocket，绑定到本机的8899端口上        ServerSocket server = new ServerSocket();        server.bind(new InetSocketAddress("localhost", 8899));        // 接受客户端的连接请求;accept是一个阻塞方法，会一直等待，到有客户端请求连接才返回        while (true) {            Socket socket = server.accept();            new Thread(new ServiceServerTask(socket)).start();        }    }}

服务端任务线程代码：

package cn.itcast.bigdata.socket;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStream;import java.io.PrintWriter;import java.net.Socket;public class ServiceServerTask implements Runnable{    Socket socket ;    InputStream in=null;    OutputStream out = null;    public ServiceServerTask(Socket socket) {        this.socket = socket;    }    //业务逻辑：跟客户端进行数据交互    @Override    public void run() {         try {            //从socket连接中获取到与client之间的网络通信输入输出流             in = socket.getInputStream();            out = socket.getOutputStream();            BufferedReader br = new BufferedReader(new InputStreamReader(in));            //从网络通信输入流中读取客户端发送过来的数据            //注意：socketinputstream的读数据的方法都是阻塞的             String param = br.readLine();            GetDataServiceImpl getDataServiceImpl = new GetDataServiceImpl();            String result = getDataServiceImpl.getData(param);            //将调用结果写到sokect的输出流中，以发送给客户端            PrintWriter pw = new PrintWriter(out);            pw.println(result);            pw.flush();        } catch (IOException e) {            e.printStackTrace();        }finally{            try {                in.close();                out.close();                socket.close();            } catch (IOException e) {                e.printStackTrace();            }        }    }}

getData函数：

package cn.itcast.bigdata.socket;public class GetDataServiceImpl {    public String getData(String param){        return "ok-"+param;    }}

客户端：

package cn.itcast.bigdata.socket;import java.io.BufferedReader;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStream;import java.io.PrintWriter;import java.net.Socket;public class ServiceClient {    public static void main(String[] args) throws Exception {        /*ServiceIterface service = ProxyUtils.getProxy(ServiceIterface.class,"methodA",hostname,port);        Result = service.methodA(parameters);*/        // 向服务器发出请求建立连接        Socket socket = new Socket("localhost", 8899);        // 从socket中获取输入输出流        InputStream inputStream = socket.getInputStream();        OutputStream outputStream = socket.getOutputStream();        PrintWriter pw = new PrintWriter(outputStream);        pw.println("hello");        pw.flush();        BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));        String result = br.readLine();        System.out.println(result);        inputStream.close();        outputStream.close();        socket.close();    }}
