Spring MVC - No mapping found for request URI?

Question

I get some problem using spring MVC Here is my web.xml config

<!-- config spring --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/applicationContext.xml, /WEB-INF/classes/xfire-servlet.xml, /WEB-INF/classes/mvc-servlet.xml, classpath:org/codehaus/xfire/spring/xfire.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <listener> <listener-class> org.springframework.web.util.IntrospectorCleanupListener </listener-class> </listener> <!-- spring mvc --> <servlet> <servlet-name>mvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>mvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> 

My controller is watching

 @Controller @RequestMapping("/searchCase.do") public class SearchCaseController { public String getCaseDetailInfo() { return "forward:caseDetail"; } } 

and my mvc configuration

 <!--auto scan annotation --> <context:component-scan base-package="com.thunisoft.shxt.webservice.model.searchCase.logic" /> <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/jsp/case" /> <property name="suffix" value=".jsp" /> </bean> 

Then I request the url: http: // {address: port} / {application-name} /searchCase.do, But it cannot find the controller to resolve my request with

  No handler found in getLastModified DispatcherServlet with name 'mvc' processing request for [/{application-name}/searchCase.do] No mapping found for HTTP request with URI [/{application-name}/searchCase.do] in DispatcherServlet with name 'mvc' Successfully completed request 

My spring MVC version is 2.5.6. I am waiting for your questions to help me solve this problem, thanks!

Answer 1

Change the controller url pattern as i said below

.do will be automatically added to the entire controller request mapping as you configured in web.xml

 @Controller @RequestMapping("/searchCase") public class SearchCaseController { public String getCaseDetailInfo() { return "forward:caseDetail"; } } 

JSP Code:

 <a href="/searchCase.do">Click</a> 

Answer 2

Try adding method level annotation as follows:

 @Controller @RequestMapping("/searchCase") public class SearchCaseController { @RequestMapping(method = RequestMethod.GET) public String getCaseDetailInfo() { return "forward:caseDetail"; } } 

As described in the docs: Matching Requests with @RequestMapping

17.3.2 Matching Requests Using @RequestMapping

You use the @RequestMapping annotation to map URLs such as /appointments to the entire class or specific handler method. Typically, class-level annotation maps a specific request path (or path template) to a form controller, with an additional level of annotation method, narrowing the primary mapping for a particular HTTP method, the request method ("GET", "POST", etc.) or the request parameter HTTP status.

What people suggest in the comments is what docs describes

After initializing the DispatcherServlet, Spring MVC looks for a file named [servlet-name] -servlet.xml in the WEB-INF directory of your web application and creates beans there, overriding the definitions of any beans defined with the same name in the global scope.

However, using the configuration

 <init-param> <param-name>namespace</param-name> <param-value>mvc</param-value> </init-param> 

you overdo it, so the DispatherServlet file will look like this

 DEFAULT_CONFIG_LOCATION_PREFIX + getNamespace() + DEFAULT_CONFIG_LOCATION_SUFFIX 

so in your example it will be

 /WEB-INF/mvc.xml 

I see for your comment that you originally had your own name (corresponding to your configuration). Thus, it is either that you did not place it under WEB-INF, or your problems are located elsewhere.

Speaking of this, consider an alternative configuration (clearer in my opinion) based on the contextConfigLocation parameter, for example

 <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/mvc-servlet.xml</param-value> </context-param> 

Hope this helps

I am setting up my project on my computer. First, I start the project using maven-jetty-plugin . Then no detection error was found. After many changes, finally I tried maven-tomcat7-plugin , then it worked.

Add tomcat plugin to your pom.xml

  <build> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> </plugin> </plugins> </build> 

Then start the mvn tomcat7:run server

Your controller mapping should be like this:

 @RequestMapping(value="/searchCase", method = RequestMethod.GET) public ModelAndView helloWorld() {

I had the same error. After checking everything that I found during the stack overflow, I didn’t understand anything, I realized that I have a controller in the src/main/resources/com/controllers folder, where com.controllers was supposed to be a package.

Creating another src/main/java source folder and moving the com/controllers folder there did the trick. (He found the com/controller folder as a package, whereas in src/main/resources it was considered as a regular directory.)
