JAVA SOCKET多线程等待接受客户端信息实现

服务端程序：

public class Demo {

public static void main(String[] args) {

// TODO 自动生成的方法存根

try {

ServerSocket server =new ServerSocket(6666);

Socket client = null;

int i=0;

while(true) {

client = server.accept();

new Thread(new ServerThread(client)).start();

i++;

System.out.println("当前是第:"+i+"个用户连进来了。接入的客户端的IP地址:"+client.getInetAddress().getHostAddress());

}

} catch (Exception e) {    // TODO 自动生成的 catch 块    e.printStackTrace();   }  }

}

class ServerThread implements Runnable{

Socket client =null;

ServerThread(Socket temp){

this.client=temp;

}

@Override

public void run() {

// TODO 自动生成的方法存根

try {

InputStream in = client.getInputStream();

InputStreamReader reader = new InputStreamReader(in);

BufferedReader buff = new BufferedReader(reader);

String str="";

while((str=buff.readLine())!=null){

System.out.println("接受到客户端请求:"+str);

}

client.shutdownInput();

OutputStream out = client.getOutputStream();

PrintWriter p = new PrintWriter(out);

p.write("欢迎您");

p.flush();

reader.close();

in.close();

p.close();

out.close();

client.close();

} catch (IOException e) {

// TODO 自动生成的 catch 块

e.printStackTrace();

}

}

}

客户端程序:

public class Demo {

public static void main(String[] args) {

// TODO 自动生成的方法存根

try {

Socket client =new Socket(InetAddress.getLocalHost(),6666);

OutputStream out = client.getOutputStream();

String str="登录名:张三 密码:123";

out.write(str.getBytes());

out.flush();

client.shutdownOutput();

InputStream in = client.getInputStream();

InputStreamReader reader =new InputStreamReader(in);

BufferedReader buff =new BufferedReader(reader);

String request="";

while((request=buff.readLine())!=null) {

System.out.println("获取服务端返回:"+request);

}

out.close();

reader.close();

in.close();

client.close();

} catch (UnknownHostException e) {

// TODO 自动生成的 catch 块

e.printStackTrace();

} catch (IOException e) {

// TODO 自动生成的 catch 块

e.printStackTrace();

}

} }
