private void indexInfo(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { List<Category> cates = this.cateService.findAllCate(10); List<Goods> starGoodes = this.goodsService.findGoodsByState(4, 5); List<Goods> homeGoodes = this.goodsService.findGoodsByCate(3, 8); List<Goods> smartGoodes = this.goodsService.findGoodsByCate(5, 5); List<Goods> hotGoodes = this.goodsService.findGoodsByState(1, 4); String info = CookieUtils.getCookieInfo(request); List<Goods> tjGoodes = null; if ("".equals(info)) { tjGoodes = this.goodsService.findGoodsByState(2, 5); } else { tjGoodes = this.goodsService.findGoodsBySearch(info, 5); } request.setAttribute("cates", cates); request.setAttribute("starGoodes", starGoodes); request.setAttribute("homeGoodes", homeGoodes); request.setAttribute("smartGoodes", smartGoodes); request.setAttribute("hotGoodes", hotGoodes); request.setAttribute("tjGoodes", tjGoodes); request.getRequestDispatcher("index.jsp").forward(request, response); }

这段代码是一个Java Servlet的方法，它接收一个HTTP请求和一个HTTP响应，并向请求中添加一些属性，然后将请求转发到index.jsp页面。在这个方法中，它首先使用cateService查找所有类别，然后使用goodsService查找状态为4和5的商品，使用goodsService查找类别为3和8的商品，使用goodsService查找类别为5和5的商品和状态为1和4的商品，根据请求中的Cookie信息查找推荐商品。最后，将所有查找到的商品和类别添加到请求属性中，然后将请求转发到index.jsp页面。

@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。
