我試圖設置一個框架Spring 3 MVC項目，但我很難得到視圖渲染。我遵循mvc-basic示例項目中描述的結構並在http://blog.springsource.com/2009/12/21/mvc-simplifications-in-spring-3-0/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+Interface21TeamBlog+%28SpringSource+Team+Blog%29上設置web.xml,app-config.xml和mvc-config.xml文件。控制器被調用，但是當它達到查找視圖並呈現它時，我得到一個404錯誤。該文件如下：春天3 MVC - 控制器被調用，但沒有發現意見

在 「Java的資源：SRC」 - > com.myProject - >HelloWorldController.java我有：
package com.myProject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping(value="/helloworld")
public class HelloWorldController {
@RequestMapping(method=RequestMethod.GET)
public ModelAndView helloWorld() {
ModelAndView mav = new ModelAndView();
mav.setViewName("helloworld");
mav.addObject("message", "Hello World!");
return mav;
}
@RequestMapping(value="/Second", method = RequestMethod.GET)
public ModelAndView Second(){
ModelAndView mav = new ModelAndView();
mav.setViewName("Second");
mav.addObject("message", "Hello World!");
return mav;
}
}
和的WebContent/WEB-INF /意見我有：
WebContent (folder)
WEB-INF (folder)
views (folder)
helloworld (folder)
helloworld.jsp (.jsp view)
helloworld.jsp (.jsp view)
welcome.jsp (.jsp view)
視圖有直接的HTML在他們。當我要求http：// localhost：8080/projectname/app我正確得到了意見 - > welcome.jsp頁面。但是，當我請求http：// localhost：8080/projectname/app/helloworld或http：// localhost：8080/projectname/app/helloworld/執行命中正確的控制器操作，但我得到HTTP狀態404 - /projectname/WEB-INF/views/helloworld.jsp
任何人都可以告訴什麼是錯的？
感謝
對於控制器類（'HelloWorldController'）和其中的一個方法（'Second（）'），您有不同的'@ RequestMapping'值。你是否試圖將'value =「/ helloworld」'放入'helloWorld（）'的'@ RequestMapping'而不是類註解？ – Jan 2010-10-25 08:53:03
我一般我同意@GaryF：在URLs（「/ app/helloworld」v.s.「/ helloworld」）中存在不匹配。也許將註釋重寫爲'@RequestMapping（value =「/ app/helloworld」）'然後使用'UrlRewriteFilter'會更容易。或者你的類註解應該聲明'@RequestMapping（value =「/ app」）'方法註解應該聲明'@RequestMapping（value =「/ helloworld」）'（相對映射，參見[here]（http：// static。 springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-ann-requestmapping））。 – 2011-11-17 08:56:08
