Spring MVC BeanNameUrlHandlerMapping example

In Spring MVC,

BeanNameUrlHandlerMapping

is the default handler mapping mechanism, which maps URL requests to the name of the beans. For example,

<beans ...>

<bean
class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>

<bean name="/welcome.htm"
class="com.mkyong.common.controller.WelcomeController" />

<bean name="/streetName.htm"
class="com.mkyong.common.controller.StreetNameController" />

<bean name="/process*.htm"
class="com.mkyong.common.controller.ProcessController" />

</beans>

In above example, If URI pattern

/welcome.htm

is requested,

DispatcherServlet

will forward the request to the “

WelcomeController

“.

/streetName.htm

is requested,

DispatcherServlet

will forward the request to the “

StreetNameController

“.

/processCreditCard.htm

or

/process{any thing}.htm

is requested,

DispatcherServlet

will forward the request to the “

ProcessController

“.

Note

Additionally, this mapping is support Ant style regex pattern match.

Actually, declare

BeanNameUrlHandlerMapping

is optional, by default, if Spring can’t found handler mapping, the

DispatcherServlet

will creates a

BeanNameUrlHandlerMapping

automatically.

So, the above

web.xml

file is equivalence to the following

web.xml

:

<beans ...>

<bean name="/welcome.htm"
class="com.mkyong.common.controller.WelcomeController" />

<bean name="/streetName.htm"
class="com.mkyong.common.controller.StreetNameController" />

<bean name="/process*.htm"
class="com.mkyong.common.controller.ProcessController" />

</beans>
