SpringMVC: DispatcherServlet makes extra requests to view

Question

I'm having a strange problem with Spring MVC. I have a simple controller like this:

@Controller
@RequestMapping("admin")
public class AdminController {

@RequestMapping(value = "", method = RequestMethod.GET)
public String home() {
    return "home";
}

When I run my server and access the url: localhost/admin I get a 404 error. The view home.jsp exists and should be rendered. When I check my spring event log this is what shows up:

DEBUG: org.springframework.web.servlet.DispatcherServlet - DispatcherServlet with name 'appServlet' processing GET request for [/admin]
DEBUG: org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Looking up handler method for path /admin
DEBUG: org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Returning handler method [public java.lang.String be.roots.buildinginspector.web.controller.AdminController.home()]

WARN : org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/home] in DispatcherServlet with name 'appServlet'

Everything is handled correctly but instead of just showing the view, the DispatcherServlet makes a new GET request to the url of the requested view name.

My web.xml:

<?xml version="1.0" encoding="UTF-8"?>

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<!-- The definition of the Root Spring Container shared by all Servlets and Filters -->

<filter>
    <filter-name>hiddenHttpMethodFilter</filter-name>

</filter>

<filter-mapping>
    <filter-name>hiddenHttpMethodFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

Relevant spring context parts (config-core-web.xml):

<resources mapping="/resources/**" location="../../../resources" />

<!-- Resolves views selected for rendering by @Controllers to .jsp resources
     in the /WEB-INF/views directory -->
<beans:bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <beans:property name="prefix" value="/WEB-INF/views/"/>
    <beans:property name="suffix" value=".jsp"/>
</beans:bean>

I had the same problem, tank you, by the way, i can see you are reading Apress.Pro.Spring.3.Apr.2012. — OJVM, Oct 19 '12 at 14:05

@Controller
@RequestMapping("admin")
public class AdminController {

@RequestMapping(method = RequestMethod.GET)
public String home() {
    return "home";
}

remove 'value' property of @RequestMapping for home() function.

This still gives the same weird behaviour. The log displays the same: the correct controller / view gets found but after it tries to display it another get request is made to the url the controller method returns. – Geoffrey De Vylder May 10 '12 at 13:07
Whats in config-core-web.xml file. May be u give in that file also. – Sachin J May 10 '12 at 13:38
Remove hiddenHttpMethodFilter and try once. – Sachin J May 10 '12 at 13:43
config-core-web.xml contains my view resolver and resources mapping – Geoffrey De Vylder May 10 '12 at 13:45

After all it turned out this was a tomcat-related issue. For some reason when I recreated the configuration in my IDE the error was resolved. Thanks for your help.

I think this is servlet mapping problem in web.xml. Change it in web.xml to /admin addreses only. Perhaps now you have:

<url-pattern>*</url-pattern>

change it to:

<url-pattern>/admin/*</url-pattern>

My is /, which has been recommended on a couple of sites I've visited – Geoffrey De Vylder May 10 '12 at 13:09
@geoffreydv: yes you do. But than all requests will be processed with spring DispatcherServlet. So you don't have to surprise that you have two calls of DispatcherServlet. And, ok, you will define controller that process /home url and return "newurl". It still go to Dispatcher servlet. What next will you do? – alexey28 May 10 '12 at 13:30

The request mapping annotation defined over your methode restrict your controller to responds to requests starting with "/admin/home".

I would apply the following modifications :

@Controller
@RequestMapping("/admin")
public class AdminController {

   @RequestMapping(method = RequestMethod.GET)
   public String home() {
      return "home";
   }
}

Try this:

@RequestMapping(value = "admin",
        method = {RequestMethod.GET, RequestMethod.POST })
