<bean name="appController" class="com.test.web.controller.AppController" >
    </bean>

but if i remove

<mvc:resources mapping="/help/**" location="/help/" />

this tag, it's working fine. I spend lot time to figure this one :( Thanks in advance

回答1:

After adding these two tags, it is finally worked..

<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/> 
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
    <property name="order" value="0"/>
</bean>

Thanks everyone :)

回答2:

In my case, I needed to add this adapter too.

    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>

回答3:

If it is a portlet, like liferay portlet then you need to add

...<bean class="org.springframework.web.portlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> also make sure that your controller has @Controller annotation and your controller method has @RequestMapping("VIEW")
