Java 在Springmvc中配置注释

java spring-mvc

Java 在Springmvc中配置注释,java,spring-mvc,annotations,Java,Spring Mvc,Annotations,运行springmvc应用程序时出现以下错误。在我的控制器文件中，我使用注释将viewAll.view映射到displagyinventory/ListAll.jsp，但这似乎不起作用。 我可以使用控制器文件中的sysout在控制台中看到消息“In ViewDVDController.viewAll（）” 如果我缺少一些映射，请告诉我好吗 Error: HTTP Status 404 - /SpringMVC/views/inventory/viewAll.jsp -------------

ViewDVD控制器位于哪个软件包中？请注意，基本软件包的值（在cotext:component scan中）必须与您的软件包名称匹配

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

有三个包，springmvc.application、springmvc.application.impl和springmvc.controller。ViewDVDController在springmvc.controller包中。我添加了log4j输出以提供更多信息。顶部第3行抱怨“无法找到名为“viewNameTranslator”的RequestToViewNameTranslator:使用默认值…”这可能是罪魁祸首吗？ 
    @Controller
    public class ViewDVDController extends MultiActionController {
        public ViewDVDController(){
            System.out.println("In ViewDVDController()");
        }
        @Autowired
        private InventoryManager manager;

        public InventoryManager getManager(){
            return manager;
        }

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

        @RequestMapping(value="viewAll.view", method=RequestMethod.GET)
        public ModelAndView viewAll() throws Exception {
            System.out.println("In ViewDVDController.viewAll()");
            Collection<DVDInfo> all = manager.getAll();
            return new ModelAndView("ListAll","catalog",all);

        }


    }
