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("/admin/managecoursesUrl") public class ManageCourseController extends HttpServlet { private static final long serialVersionUID = 1L; public ManageCourseController() { super(); // TODO Auto-generated constructor stub } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { CoursesService coursesSerice = new CoursesService(); List<Courses> courses = coursesSerice.getCourseList(); request.setAttribute("courses", courses); request.getRequestDispatcher("/WEB-INF/pages/manage-course.jsp").forward(request, response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub doGet(request, response); } }
这是一个基于Servlet的Java Web应用程序中的ManageCourseController类。它处理/admin/managecoursesUrl的GET请求,通过CoursesService获取课程列表并将其作为属性添加到请求中,然后将请求转发到manage-course.jsp页面。POST请求也会被转发到相同的方法。
