When i clik on test I get this error in the sts log:

WARNING: No mapping for GET /example/hello
You should use '/' for mapping for your controllers.
You could try this:
#RequestMapping("/example/hello")
public String redirect() {
return "viewpage";
}
And it's better to use relative path for links:
View test
Click here...

I am trying to execute a Spring MVC application that uses Spring MVC theme feature. I am following this example https://www.youtube.com/watch?v=OiQql85qsos But somehow its not working, here is the project structure in STS
I just have a HomeController

public class HomeController {

public String getHomePage(){
return "home";
}

Below is the content of theme-black.css (under WebContent/resources/css)

Here is the home.jsp but on clicking on other themes link it does not change the themes
I checked the cookies , there is a cookie with name org.springframework.web.servlet.theme.CookieThemeResolver.THEME
How to make it work ?
First off all your interceptor setup is flawed. You are using <mvc:annotation-driven /> and as such should use the <mvc:interceptors /> to register your interceptors. You should remove the DefaultAnnotationHandlerMapping bean.
<mvc:interceptors>
<ref bean="themeChangeInterceptor"/>
</mvc:interceptors>
Next to be able to use the selected theme in your JSP you have to use the theme tag from the Spring tag library.
<%# taglib prefix="spring" uri="http://www.springframework.org/tags"%>
Then in your header include the stylesheet you want to use.
<head>
<link rel="stylesheet" href="<spring:theme code='styleSheet'/>" type="text/css"/>
</head>

Why does Spring MVC respond with a 404 and report "No mapping found for HTTP request with URI [...] in DispatcherServlet"?

Closed 5 years ago.
Im new to MVC. Ive been able to do the tutorial of a couple examples with no problem. Im going to send this project .war file to a potential employer. And he's impatiently waiting.

If your application starts without errors the problem could be in your servlet mapping.
You map it as:
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
which means mapping to root context. Try to change it to following
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
Just insure whether you have entry of component scan in servlet-context.xml file.
<context:component-scan base-package="com.productstore.service.*" />
let me know if you still face the issue.
I am new to Spring and have looked at countless examples and cannot figure out this problem. The issue that I have is that when I click the link from my index.jsp page it does not forward to the hello.jsp page. I do not know why. I have spent 2 days looking up examples and trying countless examples trying to determine what the problem is to no avail. I am hoping you can tell me what the issue is. I am using NetBeans 7.2, Tomcat 7, JDK 7, Spring 3.2.1. The redirect.jsp works to get to the index.jsp page, but clicking the link on the index.jsp page gives me a 404 error.
The way I understand it, the welcome-file is the redirect.jsp (not sure how this file is handled and why it is not gine through the dispatcher - because it is a jsp?). This redirects to an htm file. The dispatcher finds a url mapping that matches the index.htm and calls the indexController, which sends to the "index" view, which is "/WEB-INF/jsp/" + index + ".jsp".
When Tomcat starts up I see the following messages:
Mapped URL path [/helloworld] onto handler 'helloWorldController'
Mapped URL path [/helloworld/*] onto handler 'helloWorldController'
Mapped URL path [/index.htm] onto handler 'indexController'
Clicking the link in the index.jsp gives the following warning message:
No mapping found for HTTP request with URI [/WTSpring3/hello.htm]
My web files are layed out as follows:
web
WEB-INF
jsp
hello.jsp
index.jsp
applicationContext.xml
dispatcher-servlet.xml
web.xml
redirect.jsp
redirect.jsp
<% response.sendRedirect("index.htm"); %>
index.jsp (this is the one I can never get to work. I am not sure if I have the link incorrect of the Spring setup).
<html><body>
Say Hello
</body></html>
hello.jsp
<html>
<body>${message}</body>
</html>
web.xml
- note he url-pattern here is *.htm, which is what I use in my index.jsp.

Add a new bean to dispatcher-servlet.xml
<bean id="helloWorldController"
class="net.mvp.spring3.controller.HelloWorldController" />
replace your bean with id urlMapping with the given below code
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="index.htm">indexController</prop>
<prop key="hello.htm">helloWorldController</prop>
</props>
</property>
Note : No need to change the #RequestMapping("hello")
Can you change hello.htm filename to hello2.jsp or something like this? I mean, try to use different name from request mapping.
#Controller
public class HelloWorldController {
#RequestMapping("hello") // what the user calls for, the request
public ModelAndView helloWorld() {
String message = "Hallo Asgard";
return new ModelAndView("hello2", "message", message); // the response
//"hello" in ModelAndView is the same "hello" as the one in views.xml
}
}
hello2.jsp
<html>
<body>${message}</body>
</html>
There are probably other ways to do this but this is how i learned it, with view beans.
What happens is the following:
the user clicks a link with a certain name i.e. www.yoursite.com/hello
spring looks for 'hello' in the requestmappings.
if the requestmapping is found, the corresponding method is executed.
that method returns a ModelAndView containing the alias(hello) of an url(WEB-INF/jsp/hello.jsp) that must be defined in the views.xml that is in the same location as your jsp files.
finally the page from the url(WEB-INF/jsp/hello.jsp) of the alias hello is shown to the user.
The views.xml defines the aliases for the urls of the different jsp files. So in that file you say that hello corresponds to WEB-INF/jsp/hello.jsp.
It looks something along these lines:
<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/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
<bean id="excelViewResolver" class="org.springframework.web.servlet.view.XmlViewResolver">
<property name="order" value="1"/>
<property name="location" value="/WEB-INF/views.xml"/>
</bean>
<!-- in views.xml -->
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean id="hello" class="org.springframework.web.servlet.ModelAndView">
<property name="hello" value="/WEB-INF/jsp/hello.jsp" />
</bean>
</beans>
The requestmapping in your controller looks the same:
#Controller
public class HelloWorldController {
#RequestMapping("hello") // what the user calls for, the request
public ModelAndView helloWorld() {
String message = "Hallo Asgard";
return new ModelAndView("hello", "message", message); // the response
//"hello" in ModelAndView is the same "hello" as the one in views.xml
}
}
I hope that helps you out.
My application's folder structure is as follows.
web/WEB-INF/templates/
-home.ftl
web/resources/css/Home_files
-test.css
When using both <mvc:annotation-driven /> and <mvc:resources mapping="/resources/**" location="/resources/css/Home_files" /> tags it couldn't resolve view (http://localhost:8080/info/home/index.html).
without <mvc:resources mapping="/resources/**" location="/resources/css/Home_files" /> tag view is resolved but images ans css couldn't resolve.
without <mvc:annotation-driven /> tag view could not be resolved but images and css could be resolved.
How do i load both view and static content together?
here is my config xml files and homeController.

It seems that path is not correct in <mvc:resources> tag. Add a forward slash (/) at the end of location.
Instead of
<mvc:resources mapping="/resources/**" location="/resources/css/Home_files" />
Use this:
<mvc:resources mapping="/resources/**" location="/resources/css/Home_files/" />
I'm trying to set up a skeleton Spring 3 MVC project but i'm having difficulties getting the views to render. I have followed the structure as described in the mvc-basic sample project and at http://blog.springsource.com/2009/12/21/mvc-simplifications-in-spring-3-0/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+Interface21TeamBlog+%28SpringSource+Team+Blog%29 to set up the web.xml, app-config.xml and mvc-config.xml files. The controller gets called but when it reaches the point of finding the view and rendering it i get a 404 error. The files are as follows:

In "Java Resources : src" -> com.myProject -> HelloWorldController.java i have:
package com.myProject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
#Controller
#RequestMapping(value="/helloworld")
public class HelloWorldController {
#RequestMapping(method=RequestMethod.GET)
public ModelAndView helloWorld() {
ModelAndView mav = new ModelAndView();
mav.setViewName("helloworld");
mav.addObject("message", "Hello World!");
return mav;
}
#RequestMapping(value="/Second", method = RequestMethod.GET)
public ModelAndView Second(){
ModelAndView mav = new ModelAndView();
mav.setViewName("Second");
mav.addObject("message", "Hello World!");
return mav;
}
}
and in WebContent/WEB-INF/views i have:
WebContent (folder)
WEB-INF (folder)
views (folder)
helloworld (folder)
helloworld.jsp (.jsp view)
helloworld.jsp (.jsp view)
welcome.jsp (.jsp view)
The views have straighforward html in them. When i request http://localhost:8080/projectname/app i correctly get the the views -> welcome.jsp page. However when i request http://localhost:8080/projectname/app/helloworld or http://localhost:8080/projectname/app/helloworld/ execution hits the correct controller actions but i get HTTP Status 404 - /projectname/WEB-INF/views/helloworld.jsp
Can anyone advise as to what is wrong?
Thanks
There are a few issues. The first one is that you only dispatch /app/* urls to Spring in your web.xml:
<url-pattern>/app/*</url-pattern>
That's fine if the request mapping was /app/helloworld, but means that /helloworld doesn't even get to spring. What you're probably wanting to do is to use a urlrewrite filter to map requests into the /app/* space.
Take a dependency on tuckey and then add this to your web.xml:
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>UrlRewriteFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Then add a file called urlrewrite.xml in your WEB-INF directory, containing:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.0//EN" "http://tuckey.org/res/dtds/urlrewrite3.0.dtd">
<urlrewrite default-match-type="wildcard">
<rule>
<from>/images/**</from>
<to>/images/$1</to>
</rule>
<rule>
<from>/scripts/**</from>
<to>/scripts/$1</to>
</rule>
<rule>
<from>/styles/**</from>
<to>/styles/$1</to>
</rule>
<rule>
<from>/**</from>
<to>/app/$1</to>
</rule>
<outbound-rule>
<from>/app/**</from>
<to>/$1</to>
</outbound-rule>
</urlrewrite>
After that, a request to /helloworld should go to the correct place. You'll probably want to change the root view controller too:
<mvc:view-controller path="/" view-name="welcome"/>
Looks like it is because you have not specified the viewClass property.
Can you try with
<bean 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>
It works for welcome page due to this
<mvc:view-controller path="/app" view-name="welcome"/>
I think the view needs to be in views/helloworld.jsp and not in views/helloworld/helloworld.jsp
You should set view Name as
mav.setViewName("/helloWorld/helloWorld");
You should change "mvc-config" to yourname-servlet.xml" yourname should be match with your servlet name in ur web.xml file that in ur case should be myservlet-servlet.xml because the spring dispatcher servlet look for the file with "-servlet" extension file name in WEB-INF folder.
and in your myservlet-servlet.xml file for suffix part you should say in this way : "WEB-INF/yourfoldername(e.g. view)" till your controller look for ur view name that u mentioned in ur controller method (e.g ModelAndView("hello")).
As you have following configuration:
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
and your controller returning clean view name.
Verify your view files exists inside /WEB-INF/views/ while you run application.
