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

Closed 5 years ago.
In setting up a Spring app (packaged as a WAR and hosted via Tomcat) I'm getting a 404 and the following error when I try to visit 'localhost:8080':
4479 [http-bio-8080-exec-1] WARN org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/WEB-INF/pages/index.html] in DispatcherServlet with name 'spring'
There is most definitely a /WEB-INF/pages/index.html file.
Here's my web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
Additionally, here's my spring-servlet.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com.company.app.controller" />
<mvc:annotation-driven />
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value= "/WEB-INF/pages/"/>
<property name="suffix" value=".html"/>
</bean>
</beans>
And the get method from my controller:
package com.company.app.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
public class SplashController {
#RequestMapping(value="/", method=RequestMethod.GET)
public String index() {
return "index";
}
}
So, what's wrong with my configuration?
Additionally: I'd like to include my console output from Spring's initial setup, maybe it will provide a clue or two as to what is missing:

Answer 1

For whatever reason, changing the servlet-mapping portion of my web.xml to this solved the problem:
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

Answer 2

I use Spring 3.2.3 release. Try this configuration:
Correct web.xml:
<servlet-mapping>
<servlet-name>Spring</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
Correct Spring-servlet.xml:
<context:component-scan base-package="your.package.controller"/>
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
<bean id="internalViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:viewClass="org.springframework.web.servlet.view.JstlView"
p:prefix="/WEB-INF/jsp/"
p:suffix=".jsp"/>
<bean class="org.springframework.web.servlet.view.BeanNameViewResolver"/>
Correct mapping annotacion:
#RequestMapping(value="/index", method=RequestMethod.GET)
And create index.jsp file.

I also faced the same problem when a friend of mine suggest me to check for the package declaration.
After I knew for which package the definition of the controller request mapping and context:component-scan base-package to check for I saw it was not the same and after giving it the proper package name it started to work.
Check for the following snippet in your Spring config file
<context:component-scan base-package="your package name" >
