Spring Mvc返回html页面404错误解决记录

原文地址：http://53873039oycg.iteye.com/blog/2061992

 以前使用Spring Mvc时候都是返回jsp页面或者ftl页面，昨天想返回html页面，spring-mvc.xml配置如下：

 

<bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver"
        p:prefix="/WEB-INF/html/" p:suffix=".html" />

    Controller方法如下:

  

@RequestMapping(value = "/add", method = RequestMethod.GET)
public String toAddTest() {
    return "addTest";
}

    在tomcat下测试，页面一直是404，log日志如下：

   可以看出No mapping found for HTTP request with URI错误导致了404，问题原因:

1 First the DispatcherServlet is invoked by the Servlet Container. 

2 The DispatcherServlet finds a mapping which maps to the home method of your Controller and the home method returns a view name "HelloWorld" 

3 Now the DispatcherServlet uses a View Resolver (your InternalResourceViewResolver) to find the View to render the model through, since the name is "HelloWorld", this maps to the /WEB-INF/view/HelloWorld.html view. 

4 Now essentially a call is made to RequestDispatcher.forward("/WEB-INF/views/HelloWorld.html",.... 

5 The Servlet container at this point tries to find the servlet which can handle /WEB-INF/views/HellowWorld.html uri - if it had been a .jsp there is a JSPServlet registered which can handle rendering the jsp, however for *.html there is no servlet registered, so the call ends up with the "default servlet", which is registered with a servlet-mapping of / which probably your DispatcherServlet is. 

6 Now the Dispatcher servlet does not find a controller to handle request for /WEB-INF/views/HelloWorld.html and hence the message that you are seeing

Add this servletmapping for the JSP servlet(web.xml): 
<servlet-mapping> 
<servlet-name>jsp</servlet-name> 
<url-pattern>*.html</url-pattern> 
</servlet-mapping>

   再次访问就OK了。
