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>
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
再次访问就OK了。
