服務器端代碼：

package threadTest.socket;

import com.sun.xml.internal.messaging.saaj.util.ByteInputStream;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class SocketServer {
    public static void main(String[] args) {
        ServerSocket server = null;
        Socket socket = null;

        try {
            server = new ServerSocket(5050); //建立服務器

            System.out.println("--服務器已啓動--");

          while(true){ //保持監聽狀態
              socket = server.accept(); //開啓監聽
              Thread thread = new Thread(new ServerThread(socket)); //每一個客戶開啓一個新線程
              thread.start(); //使線程處於可運行狀態

          }
        } catch (IOException e) {
            e.printStackTrace();
        } finally { //關閉流
            try {
                server.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

服務器線程類：

package threadTest.socket;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.Socket;

/**
 * Created by Administrator on 2016/8/7.
 * 線程
 */
public class ServerThread implements  Runnable{
    private Socket socket;

    public ServerThread(Socket socket){
        this.socket = socket;
    }

    @Override
    public void run() {
        BufferedReader br = null;
        int count = 0;
        try {
            br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            String content = null;
            while((content = br.readLine()) != null){
                System.out.println("client info：" + content);
            }

        } catch (IOException e) {
            e.printStackTrace();
        } finally{
            try {
                br.close();
                socket.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

    }
}

這樣就能實現服務器多線程間通信
