Pretty URL Mapping with Spring 3.0

Question

I'm getting the following error when trying to map a URL path called "new" to a Controller method which does some logic, then displays the view "index.jsp":

WARNING: No mapping found for HTTP request with URI [/springguestbook/index.jsp] in DispatcherServlet with name 'springguestbook'

This is my Controller method:

@RequestMapping(value = "/list", method = RequestMethod.GET) public String showGuestbookEntries(HttpServletRequest request, Model model) { HttpSession session = request.getSession(true); this.guestbookService = GuestbookService.getInstance(session); model.addAttribute("guestbookEntries", guestbookService.getGuestbookEntries()); return "index"; }

These are the contents of my web.xml file:

<display-name>Spring Guestbook</display-name> <servlet> <servlet-name>springguestbook</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springguestbook</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping>

And this is the configuration of my ViewResolver:

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/"/> <property name="suffix" value=".jsp"/> </bean>

It seems to me that instead of actually reading the contents of index.jsp and displaying them, the method just redirects to index.jsp instead. How do I fix this?

Two things:

Try changing your servlet mapping to this (change /* to /):

<servlet-mapping> <servlet-name>springguestbook</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>

Make sure you're using a view resolver that can find your JSP, like InternalResourceViewResolver:

@Bean public ViewResolver viewResolver() { InternalResourceViewResolver b = new InternalResourceViewResolver(); b.setPrefix("/WEB-INF/jsp/"); b.setSuffix(".jsp"); return b; }

or

 <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean>

I don't mean to be greedy, but do you mind giving my answer an up-vote?
