Spring MVC-找不到页面错误

Question

我正在尝试实现muliple file upload教程的变体，并且在运行应用程序时遇到问题。

我使用模板在Eclipse中创建了一个Spring MVC项目。

控制器已由

实施

@Controller
public class FileUploadController {

    @RequestMapping(value = "/show", method = RequestMethod.GET)
    public String displayForm() {
       return "uploadForm";
    }

    @RequestMapping(value = "/save", method = RequestMethod.GET)
    public String save(@ModelAttribute("uploadForm") FileUploadForm uploadForm, Model map) {
       //get file name and copy to server location
       return "uploadSuccess"
    }

其中uploadForm和uploadSuccess是Views

中的JSP页面

我的web.xml文件定义为

<display-name>SampleFileUpload</display-name>

<servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>*.html</url-pattern>
</servlet-mapping>

，spring-servlet.xml文件定义为

<context:annotation-config />
<context:component-scan base-package = "com.jasonjohns.spring.fileupload.controller" />


<bean id = "multipartResolver" class = 
    "org.springframework.web.multipart.commons.CommonsMultipartResolver" />

<bean id = "jspViewResolver" class = 
    "org.springframework.web.servlet.view.InternalResourceViewResolver">

    <property name = "viewClass" value = 
    "org.springframework.web.servlet.view.JstlView" />
    <property name = "prefix" value = "/WEB-INF/views/" />
    <property name = "suffix" value = ".jsp" />     
</bean>

但是，当我启动应用程序时没有发现错误，即使我转到localhost:8080/SampleFileUpload/show.html，服务器也会返回404错误。你猜它是一个控制器错误，但我无法理解它背后的原因。

您是否尝试更改映射：

@RequestMapping（value =“/ show”，method = RequestMethod.GET）

到

@RequestMapping（value =“/ show.html”，method = RequestMethod.GET）
