Spring MVC：ERROR 404-Description原始服务器没有找到目标资源的当前表示，或者不愿意

标签： spring maven spring-mvc spring-boot

我是Spring框架的初学者。我试图在Spring MVC框架中构建一个购物项目。该项目是实施购物车（但规模较小）。它包含2个JSP文件作为视图，用于接收用户请求并对其进行响应，即ViewAddproduct.jsp和ViewCart.asp。此外，该项目还有4个文件pom.xml，web.xml，NikiAbb-servlet.xml和AddController.java。 （我打开Maven项目并添加所有必需的依赖项）似乎我的文件中的所有代码或添加的依赖项都是正确的，我可以在服务器（Tomcat）上单独运行每个页面。但是当我运行整个包时，我得到错误404.我已经检查了很多教程来解决它，但它没有工作。任何帮助，将不胜感激。

我正在使用JDK 9.0.4，面向Web开发人员的Eclipse Java EE IDE。氧气2释放（4.7.2）和Tomcat 9

1 个答案:

答案 0 :(得分：0)

@ NikiAbb-servlet.xml文件<property name = "prefix" value = "/WEB-INF/jsp/" />应该<property name = "prefix" value = "/WEB-INF/" />无法在WEB-INF下看到任何jsp文件夹。

@ Addcontroller.java @RequestMapping("/add") public ModelAndView.add(HttpServletRequest request,HttpServletRespose rsponse)应删除＆＃34;。＆＃34; @RequestMapping("/addProd") public ModelAndView add(HttpServletRequest。甚至你的RequestMapping也错了。

另一件事mv.setViewName("ViewCart.jsp");，无需再次添加.jsp，只需更改为mv.setViewName("ViewCart");。
