Java Socket简单实现客户端与服务端通信

JavaSocket简单实现客户端与服务端通信

实现Socket通信的步骤

创建一个ServerSocket监听8888端口

等待请求

接收到请求之后使用socket进行通信，创建BufferedReader用于读取数据

创建PrintWriter,用于发送数据

关闭资源

服务端代码

packagesocket;

​

importjava.io.BufferedReader;

importjava.io.IOException;

importjava.io.InputStreamReader;

importjava.io.PrintWriter;

importjava.net.ServerSocket;

importjava.net.Socket;

​

/**

publicclassServer2{

​

 publicstaticvoidmain(String[]args){

​

   try{

     //创建一个ServerSocket监听8888端口

     ServerSocketserverSocket=newServerSocket(8888);

     //等待请求

     Socketsocket=serverSocket.accept();

     //接收到请求之后使用socket进行通信，创建BufferedReader用于读取数据

     BufferedReaderis=newBufferedReader(newInputStreamReader(socket.getInputStream()));

     Stringline=is.readLine();

     System.out.println("receivedformclient:"+line);

     //创建PrintWriter,用于发送数据

     PrintWriterprintWriter=newPrintWriter(socket.getOutputStream());

     printWriter.println("receiveddata"+line);

     printWriter.flush();

     //关闭资源

     printWriter.close();

     is.close();

     socket.close();

     serverSocket.close();

​

   }catch(IOExceptione){

     e.printStackTrace();

   }

​

 }

}

​

客户端代码

packagesocket;

​

importjava.io.BufferedReader;

importjava.io.IOException;

importjava.io.InputStreamReader;

importjava.io.PrintWriter;

importjava.net.Socket;

​

/**

*CreatedbyRogerLawon2016/10/10.

*/

publicclassClient2{

 publicstaticvoidmain(String[]args){

   Stringmsg="ClientData";

​

​

   try{

     //创建一个Socket和本地的8888端口连接

     Socketsocket=newSocket("127.0.0.1",8888);

     //使用Socket创建PrintWriter和PrintBufferedReader进行读写数据

     PrintWriterprintWriter=newPrintWriter(socket.getOutputStream());

     BufferedReaderis=newBufferedReader(newInputStreamReader(socket.getInputStream()));

     //发送数据

     printWriter.println(msg);

     printWriter.flush();

     //接收数据

     Stringline=is.readLine();

     System.out.println("receivedfromserver:"+line);

     //关闭资源

     printWriter.close();

     is.close();

     socket.close();

   }catch(IOExceptione){

     e.printStackTrace();

   }

 }

}
