WARNING: No mapping found for HTTP request with URI [ ] in DispatcherServlet with name

java, spring, spring-mvc

Solution

Return the name of the view without the `.jsp` file extension. The resolution of the view name is handled by the `InternalResourceViewResolver`.

public String sample(Model model){
    return "sample";
}

This snippet of your configuration:

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

takes the view name `sample` and applies the appropriate prefix (`/WEB-INF/jsp/`) and suffix (`.jsp`) to form the entire view name used for resolution of the view.

Also make sure the `sample.jsp` is located at `/WEB-INF/jsp/sample.jsp`.

Also when using the `@RequestMapping` annotation you must enable these annotations in the configuration for the dispatcher serlvet by including `<mvc:annotation-driven/>`.

You must also add component scanning within the dispatcher configuration so that the controllers are registered with the dispatcher servlet. Currently, you perform component scanning within the `applicationContext.xml` configuration file using:

<context:component-scan base-package="com.mindedges" />

However, since this component scanning occurs within the `applicationContext` file the registered beans (assuming they are your controllers) will not be available to the dispatcher serlvet. You must place this configuration snippet within `dispatcher-context.xml`.

You many want to consult one of my previous answers regarding the differences between the dispatcher configuration and the context configuration.

There was also some whitespace in your dispatcher-context.xml file and a the `mvc` namespace was missing. I have corrected these issues and provided them in this GitHub Gist.

I have my web.xml as ``` <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> ``` applicationContext as ``` <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd" > <context:component-scan base-package="com.mindedges" /> </beans> ``` Dispatcher servlet as ``` <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd"> <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>  <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="index.htm">indexController</prop> </props> </property> </bean> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" />  <bean name="indexController" class="org.springframework.web.servlet.mvc.ParameterizableViewController" p:viewName="index" /> </beans> ``` Controller as in package com.mindedges.testapp ``` @Controller @RequestMapping("/sample") public class SampleController { public String sample(Model model){ return "sample.jsp"; } } ``` When i hit `http://localhost:8084/TestApp/sample` .
