放置在应用程序上下文中的Spring bean无效

Question

I have worked with Spring annotations a bit, but never with spring xml. I have to create an application where all the beans are kept in applciationContext.xml file and not in xxx-dispather.xml. But when i place the beans inside xxx-dispatcher.xml i am able to hit the controller class and everything works fine, But when i place the same beans inside applciationContext.xml it does not work at all. All i get is 404 exception.

Below is my web.xml file

<web-app id="WebApp_ID" version="2.4" 
xmlns="http://java.sun.com/xml/ns/j2ee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

Below is my mvc-dispatcher-servlet.xml

    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>

</beans>

Below is my web-applicationContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans

<bean class="com.mkyong.common.controller.WelcomeController" />
<bean class="com.mkyong.common.controller.HelloGuestController" />

</beans>

Can anyone please correct me where i have gone wrong.

Answer 1

Add the following:

<mvc:annotation-driven/>
<context:component-scan base-package=""/>//the package where your controller are located

This will let you just use the controller annotation to locate you controllers.
