这段代码是用来处理一个 HTTP 请求的方法,其中包含了一些业务逻辑,主要是从数据库中获取商品信息,然后将其存入请求的属性中,最后将请求转发到 index.jsp 页面进行展示。具体来说,这个方法会获取一些指定分类的商品信息,比如星标商品、首页商品、智能家居商品等等,还会获取一些热门商品和推荐商品。其中,推荐商品的获取方式是根据用户的历史搜索信息来获取,如果用户没有搜索过,则获取状态为 2 的商品,否则根据用户的搜索信息获取商品。最终,将获取到的所有商品信息存入请求的属性中,然后将请求转发到 index.jsp 页面进行展示。

@WebServlet("/admin/tecoursesUrl") public class TeCourseController extends HttpServlet { private static final long serialVersionUID = 1L; public TeCourseController() { 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/te-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 Java Servlet,它处理了一个 URL 为 "/admin/tecoursesUrl" 的 GET 请求和 POST 请求。在 doGet 方法中,它使用 CoursesService 类获取了一个课程列表 courses,并将其设置为 request 属性 "courses",然后将请求转发到 "/WEB-INF/pages/te-course.jsp" 页面。在 doPost 方法中,它只是调用了 doGet 方法。
@WebServlet("/admin/adminUserUrl") public class AdminUserController extends HttpServlet { private static final long serialVersionUID = 1L; public AdminUserController() { super(); // TODO Auto-generated constructor stub } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { UserService userService = new UserService(); List<User>users = userService.getUserList(); request.setAttribute("users", users); request.getRequestDispatcher("/WEB-INF/pages/admin/admin-user.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AdminUserController类。它处理/admin/adminUserUrl的GET请求,通过UserService获取用户列表并将其作为属性添加到请求中,然后将请求转发到admin-user.jsp页面。POST请求也会被转发到相同的方法。
