java生成一个Socket和Servlet结合的代码例子

你好，以下是Java中生成一个Socket和Servlet结合的代码例子：

首先，需要在服务器端创建一个Servlet，假设我们的Servlet类名为MyServlet：

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

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/MyServlet")
public class MyServlet extends HttpServlet {

private static final long serialVersionUID = 1L;

public MyServlet() {
super();
}

protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// TODO Auto-generated method stub
doPost(request, response);
}

protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// TODO Auto-generated method stub
try {
Socket socket = new Socket("127.0.0.1", 8888);
PrintWriter out = new PrintWriter(socket.getOutputStream());
out.println("Hello Server");
out.flush();

BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String msg = in.readLine();
System.out.println("Message from Server: " + msg);
} catch (Exception e) {
System.out.println("Exception: " + e);
}
doGet(request, response);
}

}

上述代码中，创建了一个Socket对象，连接到本地IP地址为127.0.0.1的服务器端口号为8888的Socket服务，向服务器端发送一条“Hello Server”消息，然后等待服务器端的响应消息。

接下来，在服务器端创建一个Socket服务程序，代码如下：

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

public class SocketServer {

public static void main(String[] args) {
// TODO Auto-generated method stub
try {
ServerSocket server = new ServerSocket(8888);
while (true) {
Socket client = server.accept();
System.out.println("Connect to: " + client);
BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
PrintWriter out = new PrintWriter(client.getOutputStream());

String msg = in.readLine();
System.out.println("Message from Client: " + msg);

out.println("Hello Client");
out.flush();
}
} catch (Exception e) {
System.out.println("Exception: " + e);
}
}

}

上述代码中，创建了一个ServerSocket对象，监听本地端口号为8888的Socket服务，当有客户端连接时，创建一个Socket对象，关联到客户端的Socket服务，从客户端读取请求消息，然后向客户端发送一条“Hello Client”响应消息。
