FIXED: “No mapping found” Trying to set up a RESTfull interface using Spring-MVC

问题:

This issue is solved. Someone created a file called mvc-dispatcher.xml and it had an incorrect configuration. That file is loaded automatically because it's called the same as a servlet.

I want to thank everyone who tried to help me fix this issue. I'm keeping this question here, since it actually explains how to create a REST interface. It works perfectly.


I'm trying to set up a RESTful interface with Spring-MVC. The server starts without issue, but any time I try to call the REST interface I get the message:

41 WARN [springframework.web.servlet.PageNotFound] No mapping found for HTTP request with URI [/myweb/rest/asd/aaa] in DispatcherServlet with name 'mvc-dispatcher' 

It seems that the URL I am sending (http://localhost:8080/myweb/rest/asd/qwe for example) is not 'captured' by any controller. What am I doing wrong?

I do not know what else I could try. I'm using Java 1.7.0_15, Tomcat 7.0.34 and Spring 3.1.4.RELEASE

In my web.xml:

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">  <display-name>MyWeb</display-name> <welcome-file-list>     <welcome-file>index.xhtml</welcome-file> </welcome-file-list>  <!-- Listener for MVC spring --> <listener>     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener>     <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class> </listener>  <!-- Servlet for MVC spring -->  <servlet>     <servlet-name>mvc-dispatcher</servlet-name>     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>     <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping>     <servlet-name>mvc-dispatcher</servlet-name>     <url-pattern>/rest/*</url-pattern> </servlet-mapping>  <!-- Loading web properties --> <context-param>     <param-name>contextConfigLocation</param-name>     <param-value>/WEB-INF/applicationContext*.xml</param-value> </context-param> 

In my applicationContext.xml:

<context:component-scan base-package="com.myweb.*" /> <context:annotation-config/> <tx:annotation-driven/> <mvc:annotation-driven /> 

And finally, my controller class:

import org.apache.log4j.Logger; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping;  @Controller public class RestController {      private static Logger LOG = Logger.getLogger(RestController.class);      @RequestMapping("/asd/{test}")     public void test(@PathVariable String test) {         LOG.info("You sent "+test);     } } 

Tried changing the method's @RequestMapping but still didn't work:

@RequestMapping(method=RequestMethod.GET) public void test() {     LOG.info("You sent something"); } 

回答1:

Your mapping is wrong.

You are requesting /rest/asd/aaa but your mapping is for /asd/{test}.

You need to change @RequestMapping("/asd/{test}") to @RequestMapping("/rest/asd/{test}")

Or add @RequestMapping("/rest") to your controller class



回答2:

Try annotate your controller class also with @RequestMapping("/rest") to handle all requests with url

/webapp/rest/

You should also configure your context via org.springframework.web.context.ContextLoaderListener listener. I think You are not loading applicationContext.xml

Add this part to your web.xml

<!--spring bootstrap listener  --> <context-param>           <param-name>contextConfigLocation</param-name>           <param-value>/WEB-INF/config/applicationContext.xml</param-value>   </context-param>   <listener>       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>   </listener>
