No mapping found for HTTP request with URI Spring MVC

Question

Here's my Web.xml

<servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            /WEB-INF/spring/servlet-context.xml
        </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>

my servlet-context.xml

<context:component-scan base-package="com.springexample.controller.impl" />
    <mvc:annotation-driven />

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

And lastly the Handler class. which is under com.springexample.controller.impl

@Controller
public class IndexControllerImpl implements IndexController {

    @RequestMapping("/")
    public String index() {

        return "index";
    }
}

However on going to localhost:8080/projectname/

it returns a 404 error.

Jul 27, 2013 8:18:31 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound

Here is my project structure

What do you expect this : `/tasklist/WEB-INF/views/index.jsp` to hit ? — AllTooSir, Jul 27 '13 at 12:24
yes I do. It's here. I am wondering how come Spring is not seeing it. — user962206, Jul 27 '13 at 12:33
maybe try to add views to deployment assembly in project properties — adaniluk, Jul 27 '13 at 12:38
@donatello Like GET and POST are the only two request methods available ;) It shouldn't matter really. Leaving out the RequestMethod argument means it will take all of them (GET, POST, HEAD, OPTIONS, PUT, DELETE, TRACE). — Bart, Jul 27 '13 at 16:55
A had similar problems with Spring 2.5.x. Upgrading to 3.x solved all of them. Spring 2.5 was very quirky when it came to URL-matching. — madhead, Jul 27 '13 at 20:15
Are you sure, the only change you did was add request method to the request mapping annotation? I find it hard to believe that mentioning the request method was mandatory for you. What version of spring are you using? — Akshay, Jul 30 '13 at 11:50

With the web.xml configured they way you have in the question, in particular:

<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

ALL requests being made to your web app will be directed to the DispatcherServlet. This includes requests like /tasklist/, /tasklist/some-thing.html, /tasklist/WEB-INF/views/index.jsp.

Because of this, when your controller returns a view that points to a .jsp, instead of allowing your server container to service the request, the DispatcherServlet jumps in and starts looking for a controller that can service this request, it doesn't find any and hence the 404.

The simplest way to solve is to have your servlet url mapping as follows:

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

Notice the missing *. This tells the container that any request that does not have a path info in it (urls without a .xxx at the end), should be sent to the DispatcherServlet. With this configuration, when a xxx.jsp request is received, the DispatcherServlet is not consulted, and your servlet container's default servlet will service the request and present the jsp as expected.

Hope this helps, I realize your earlier comments state that the problem has been resolved, but the solution CAN NOT be just adding method=RequestMethod.GET to the RequestMethod.

I think Spring's documentation is partly responsible for this confusion. They use this web.xml piece ` example /example/* ` as an example, without any warning that the resolved views might go back to the dispatcher again if servlet mapping is not carefully configured. Most people would just remove the `example` part and that's how they got this strange problem. – dnang Nov 04 '13 at 14:30
You're a god and I am not and I just thought that you should know. – asteri Jan 06 '15 at 19:22
You are too kind @asteri – Akshay Jan 07 '15 at 02:27
what if I want .json to be served by the dispatcher servlet. do I have to explicitly map the url pattern? – TV Nath Nov 11 '15 at 07:50

@TharinduVishwanath yes, you will need a url pattern if you want .json requests to be served by dispatcher servlet – Akshay Nov 11 '15 at 14:11
Crazy. Thank you @AkshaySinghal. You made my working day a bit shorter today. – Christian Oct 13 '17 at 20:28
@Christian happy to help. – Akshay Oct 14 '17 at 03:08

First check whether the java classes are compiled or not in your [PROJECT_NAME]\target\classes directory.

If not you have some compilation errors in your java classes.

although it's not necessary that compiled classes should be there in target folder (unless you are using maven), but thanks for the hint!! – thekosmix Dec 09 '13 at 10:25

Try passing the Model object in your index method and it will work-

@RequestMapping("/")

public String index(org.springframework.ui.Model model) {

 return "index";

    }

Actually the spring container looks for a Model object in the mapping method. If it finds the same it will pass the returning String as view to the View resolver.

Hope this helps.

I added META-INF folder with context.xml contain

<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/SpringGradleDemo"/>

SpringGradleDemo is my project name and it work. My servlet-mapping is "/" I read it here https://tomcat.apache.org/tomcat-5.5-doc/config/context.html
