Configure the handler mapping priority in Spring MVC
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.

Nice explanation in a smart way.
Hello Mkyong,
I just spent one month in SPrings Only.I used to visit
your posts for my answers. Todays i want to ask you one question who
took whole day for crawling. I got the error as follow:
java.lang.IllegalStateException:
Cannot map handler [widgetController] to URL path [/appWidget.html]:
There is already handler
[com.org.scube.controller.WidgetController@5ac14401] mapped.
I
understood that i can map only one request for one page. But what if i
want map one request to many handlers? Please reply me as early as
possible .Will you please provide a short & simple example?
from the above example when will ControllerClassNameHandlerMapping used ,as this was given low priority
