本文介绍了一个使用Java实现的Socket通信示例，包括客户端发送登录信息和接收记录信息的方法，以及多线程ServerSocket的实现。客户端通过Socket连接到指定IP和端口的服务器，进行数据的发送和接收。

Socket端：

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.Socket;
import java.net.UnknownHostException;

public class ClientBank {

   private static String ip = "127.0.0.1";
   private static int port = 9090;
   private static Socket client = null;

   public String sendLoginSalesmanDom(String dom)throws Exception{
       String domXml = null;
       try {
           client = new Socket(ip,port);

           InputStream in = client.getInputStream();
           DataInputStream dataInput = new DataInputStream(in);

           OutputStream out = client.getOutputStream();
           DataOutputStream dataOut = new DataOutputStream(out);

           dom = "sale00" + dom;
           dataOut.writeUTF(dom);
           domXml = dataInput.readUTF();
           in.close();
           dataInput.close();
           out.close();
           dataOut.close();
           client.close();
           return domXml;
       } catch (UnknownHostException e) {
           e.printStackTrace();
       } catch (IOException e) {
           e.printStackTrace();
       }
       return domXml;
   }

   public String sendAndReturnRecardDom(String dom){
       String domXml = null;
       try {
           client = new Socket(ip,port);

           InputStream in = client.getInputStream();
           DataInputStream dataInput = new DataInputStream(in);

           OutputStream out = client.getOutputStream();
           DataOutputStream dataOut = new DataOutputStream(out);

           dom = "reca01" + dom;

           dataOut.writeUTF(dom);
           domXml = dataInput.readUTF();
           in.close();
           dataInput.close();
           out.close();
           dataOut.close();
           client.close();
           return domXml;
       } catch (UnknownHostException e) {
           e.printStackTrace();
       } catch (IOException e) {
           e.printStackTrace();
       }
       return domXml;
   }

}

多线程ServerSocket:

import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class ServerBank {
   private ExecutorService pool = Executors.newFixedThreadPool(45);

   private static int port = 9090;
   ServerSocket server = null;

   public ServerBank(){
       try {
           server = new ServerSocket(port);
           while(true){
               Socket client = server.accept();
               System.out.println("serverSocket server.accept(); ");
               ServerBankThread serverThread = new ServerBankThread(client);
               serverThread.start();
               pool.execute(serverThread);
           }
       } catch (IOException e) {
           e.printStackTrace();
       }
   }
}
