SimpleUrlHandlerMapping用法

SimpleUrlHandlerMapping是Spring MVC中適用性最強的Handler Mapping類，允許明確指定URL模式和Handler的映射關系。有兩種方式聲明SimpleUrlHandlerMapping。

prop key

key是URL模式，屬性值是Handler的ID或者名字。

<beans ...>
 
	<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
	   <property name="mappings">
		<props>
		   <prop key="/welcome.htm">welcomeController</prop>
		   <prop key="/*/welcome.htm">welcomeController</prop>
		   <prop key="/helloGuest.htm">helloGuestController</prop>
		 </props>
	   </property>
	</bean>
	
	<bean id="welcomeController" 
		class="com.mkyong.common.controller.WelcomeController" />
		
	<bean id="helloGuestController" 
		class="com.mkyong.common.controller.HelloGuestController" />
		
</beans>

value

等號左邊是URL模式，右邊是Handler的ID或者名字。

<beans ...>
	
	<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
	   <property name="mappings">
		<value>
		   /welcome.htm=welcomeController
		   /*/welcome.htm=welcomeController
		   /helloGuest.htm=helloGuestController
		</value>
	   </property>
	</bean>
	
	<bean id="welcomeController" 
		class="com.mkyong.common.controller.WelcomeController" />
		
	<bean id="helloGuestController" 
		class="com.mkyong.common.controller.HelloGuestController" />
		
</beans>
