Java Socket通信 客户端服务器端基本代码

import java.io.IOException;
import java.io.InputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class TestServer {

public static void main(String[] args) {
try {
System.out.println("启动服务端");
ServerSocket sv = new ServerSocket(2233);
//等待用户链接
Socket socket = sv.accept();
System.out.println("有用户链接！");
while (true) {
//1
InputStream is = socket.getInputStream();
//2
byte[] data = new byte[128];
is.read(data,0,data.length);
//3 按照格式转成字符串输出
String msg = new String(data, "UTF-8");
//收到的内容
System.out.println("收到的内容："+ msg);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}
