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

Question

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">

    <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");
}

Answer 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
