本文介绍了一个简单的Servlet示例，该示例通过发送HTTP 407错误响应来请求客户端进行身份验证。代码展示了如何使用doGet方法设置特定的状态码及消息。

package MyServlet;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.*;
import java.io.IOException;

 */
@WebServlet(name = "showStatus")
public class showStatus extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request,response);

    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        //设置状态吗和信息，发送给客户端
        response.sendError(407,"Need authentication!!!");

    }
}
