Error suggests springmvc-servlet.xml is wrong but on inspection it looks right?

I am learning Spring and building a sample app.

I am getting the error:

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Bean name '/list_cars.html' is already used in this file Offending resourc开发者_开发百科e: ServletContext resource [/WEB-INF/springmvc-servlet.xml]

I previously got a similar error for a project which had a springmvc-servlet.xml file for which this error was true.But when I replaced it with the file below (and deleted the previous project and restarted Tomcat) I continue to the get the error, any help would be much appreciated.

Just to make things more readable, use proper bean name when defining a bean and put url name in the urlMapping properties like below to make a url map to a controller.

<bean name="carListController" class="springmvc.web.CarListController">
        <property name="carManager" ref="carManager"/>
</bean>

    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
     <property name="mappings">
            <props>
        <prop key="/list_cars.html">carListController</prop>

            </props>
        </property>
    </bean>
