Question

I’m trying to setup and learn how to develop web applications with Spring MVC. I’ve been trying to follow a number of tutorials, but my application doesn’t seem to want to work.

Enviro: Eclipse, m2e-wtp, spring, the whole shebang

Context root is BidApp.

I have one controller:

@Controller
public class AuctionController {    
    @RequestMapping("/hello")
    public ModelAndView helloWorld() {
        String message = "Hello World, Spring 3.0!";
        return new ModelAndView("hello", "message", message);
    }
}

My web.xml in WEB-INF:

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
    <display-name>BidApp</display-name>
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
         <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring-servlet.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>*.*</url-pattern>
    </servlet-mapping>
</web-app>

And my spring-servlet.xml also in WEB-INF

<?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:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->

    <!-- Scans within the base package of the application for @Components to configure as beans -->
    <!-- @Controller, @Service, @Configuration, etc. -->
    <context:component-scan base-package="com.bidapp.controllers" />

    <!-- Enables the Spring MVC @Controller programming model -->
    <mvc:annotation-driven />
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

My I start the application and navigate to http://localhost:8080/BidApp/hello, it gives me a 404. Are my xml files in the wrong place or am I missing some configuration parameter? Is there a good place I can look at all the available parameters for configuring a spring application. The spring framework reference, unless I’m reading it wrong, isn’t helping.

Edit:

Answer 1

You must use the url pattern like this

<url-pattern>/</url-pattern>

When you add <mvc:annotation-driven /> to your config, it replaces the default set of handler mappings and handler adapters, and those defaults were the ones that handled the old-style controllers.

i think you should understand the difference between component-scan and annotation-config. If you use scan then you do not need to use config.
Difference between <context:annotation-config> vs <context:component-scan>

Please do execute with your old code with removing the <mvc:annotation-driven />

(In general)/ will be working even without mvcdefault servlethandler
