java - 在 Spring Mvc 中配置注解

运行 springmvc 应用程序时出现以下错误。在我的 Controller 文件中，我使用注释将 viewAll.view 映射到 displagy inventory/ListAll.jsp 但这似乎不起作用。我可以使用 Controller 文件中的 sysout 在控制台中看到消息“In ViewDVDController.viewAll()”。

如果我缺少一些映射，您能告诉我吗？

        }

        public void setManager(InventoryManager manager){
            this.manager=manager;

            Collection<DVDInfo> all = manager.getAll();
            return new ModelAndView("ListAll","catalog",all);

        }

最佳答案

终于，我得到了答案。我导入了错误的 ModelAndView 类 (org.springframework.web*.portlet.*ModelAndView) 而不是 Controller 文件中的 org.springframework.web.*servlet.*ModelAndView。
