accep sock 成功 服務器 命令 dos ioe println inpu 服務器端
1 public static void main(String[] args) throws IOException { 2 System.out.println("服務器開啟監聽"); 3 ServerSocket server=new ServerSocket(6666); 4 Socket client = server.accept(); 5 System.out.println("連接成功"); 6 while(true){//循環接收 7 byte用戶端[] data=new byte[1024]; 8 int count = client.getInputStream().read(data); 9 String msg= new String(data,0,count,"utf-8"); 10 if("exit".equals(msg)) 11 break; 12 else 13 System.out.println(msg); 14 } 15 client.close();16 server.close(); 17 }
1 public static void main(String[] args) throws UnknownHostException, IOException { 2 System.out.println("客戶端開始訪問"); 3 Socket client = new Socket("1.1.1.1", 6666);//參數為需要ServerSocket服務器的:IP 和 端口號,端口號是ServerSocket服務器設的端口號
4測試方法:Scanner scanner = new Scanner(System.in);
5 while(true){//循環發送
6 System.out.println("請輸入:");
7 String x=scanner.next();
8 byte[] data=x.getBytes("utf-8");
9 client.getOutputStream().write(data);
10 if("end".equals(x))
11 break;
12 }
13 client.close();
14 }
建兩個有main方法的類,把代碼分別放入類中。可以在cmd中用dos命令啟動兩個類,也可以用tomcate啟動。(註:先啟動服務器端的main方法再啟動用戶端的代碼)
