Often times, you may mix use of multiple handler mappings strategy in Spring MVC development.

For example, use ControllerClassNameHandlerMapping to map all the convention handler mappings, and SimpleUrlHandlerMapping to map other special handler mappings explicitly.

<beans ...>
 
   <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
      <property name="mappings">
		<value>
			/index.htm=welcomeController
			/welcome.htm=welcomeController
			/main.htm=welcomeController
			/home.htm=welcomeController
		</value>
      </property>
      <property name="order" value="0" />
   </bean>
 
   <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" >
      <property name="caseSensitive" value="true" />
      <property name="order" value="1" />
   </bean>	
 
   <bean id="welcomeController" 
      class="com.mkyong.common.controller.WelcomeController" />
 
   <bean class="com.mkyong.common.controller.HelloGuestController" />
 
</beans>

In above case, it’s important to specify the handler mapping priority, so that it won’t cause the conflict. You can set the priority via the “order” property, where the lower order value has the higher priority.
