//网络编程简单的理解就是两台计算机相互通讯数据,Java SDK提供一些相对简单的Api来完成这些工作.Socket就是其中之一,也是用的比较广泛的.
//其他像rmi速度还可以就是只支持java。webservice用的最广泛相对安全和速度略低于socket.废话不说了上代码
/****** * @author skiky* @describle **/
public class ClientHander {private final static Integer port = 10001;private Socket socket = null;private PrintWriter out = null;public void sendMessageToService() {try {// 获取一个IP。null表示本机InetAddress addr = InetAddress.getByName(null);// 开启端口，与服务器建立连接socket = new Socket(addr, port);out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);for (;;) {// 向服务器发送信息Thread.sleep(100 * 5);// 输出流out.println("你好 !");}} catch (IOException e) {e.printStackTrace();} catch (InterruptedException e) {e.printStackTrace();} finally {try {if (null != out) {out.close();}if (null != socket) {socket.close();}} catch (IOException e1) {e1.printStackTrace();}}}public static void main(String[] args) {new ClientHander().sendMessageToService();}
}服务端：
/***** * @author skiky* @describle socket server*/
public class ServerHander {private final static Integer port = 10001;private ServerSocket server = null;private Socket socket = null;private BufferedReader in = null;public void loadServer() {try {// createserver = new ServerSocket(port);// 等待监听是否有客户端连接socket = server.accept();// 输入流in = new BufferedReader(new InputStreamReader(socket.getInputStream()));// 打印接收到的客户端发送过来的信息for (;;) {String message = in.readLine();System.out.println("客户端信息:" + message);}} catch (IOException e) {e.printStackTrace();} finally {try {if (null != in) {in.close();}if (null != server) {server.close();}if (null != socket) {socket.close();}} catch (IOException e) {e.printStackTrace();}}}public static void main(String[] args) {new ServerHander().loadServer();}
}先运行server端再运行client 端，
输出：
客户端信息:你好 !本文链接：https://my.lmcjl.com/post/6999.html
