public class DeleteUserController extends HttpServlet { private static final long serialVersionUID = 1L; public DeleteUserController() { super(); // TODO Auto-generated constructor stub } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { Integer userId = Integer.valueOf( request.getParameter("userId")); UserService userService = new UserService(); userService.deleteUser(userId); request.getRequestDispatcher("/admin/adminUserUrl").forward(request, response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub doGet(request, response); } }

这是一个 Java Servlet 类，用于处理 HTTP GET 请求和 POST 请求。它接收一个名为 "userId" 的参数，将其转换为整数类型，然后调用 UserService 的 deleteUser 方法删除对应的用户。最后，将请求转发到 "/admin/adminUserUrl" 页面。你有什么其他的问题吗？

@WebServlet("/introduceUrl") public class IntroduceController extends HttpServlet { private static final long serialVersionUID = 1L; public IntroduceController() { super(); // TODO Auto-generated constructor stub } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub request.getRequestDispatcher("/WEB-INF/pages/introduce.jsp").forward(request, response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub doGet(request, response); } }

这是一个使用 Servlet 技术实现的介绍控制器，它提供了 doGet() 和 doPost() 两个方法来处理 GET 和 POST 请求。在 doGet() 方法中，它直接将请求转发到 "/WEB-INF/pages/introduce.jsp" 页面进行展示。在 doPost() 方法中，它直接调用 doGet() 方法来处理请求。该控制器没有实际的业务逻辑，只是用来展示介绍页面。

@WebServlet("/updateInfo") public class UpdateInfoController extends HttpServlet { private static final long serialVersionUID = 1L; public UpdateInfoController() { super(); // TODO Auto-generated constructor stub } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String description = request.getParameter("description"); User user = (User) request.getSession().getAttribute("loginUser"); request.getRequestDispatcher("/infoUrl").forward(request, response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub doGet(request, response); } }

这是一个Java Servlet，其中定义了一个名为UpdateInfoController的类。该类继承了HttpServlet类，实现了doGet和doPost方法。在doGet方法中，它首先从请求中获取名为description的参数，并从会话中获取名为loginUser的对象。然后，它将请求转发到/infoUrl页面。在doPost方法中，它只是调用了doGet方法。这个Servlet似乎没有完成更新用户信息的操作，只是将请求转发到另一个页面。
