Using Handler Mappings

[Edmund Yong]

I refer to the Spring MVC tutorial part 1 at Spring MVC step-by-step Part 1

Please see step 6. The file springapp-servlet.xml contains the following:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
 
<!--
  - Application context definition for "springapp" DispatcherServlet.
  -->
 
<beans>
    <bean id="springappController" class="SpringappController"/>
 
    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="/hello.htm">springappController</prop>
            </props>
        </property>
    </bean>
</beans>

My question is: how does Spring knows that it needs to look for a bean called urlMapping (which contains the mapping to tell Spring which controller to invoke)? As far as I know, this bean could be called anything.

Thanks in advance.
