The entire Controller class hierarchy is deprecated. The preferred usage of Spring MVC is to use @Controller-annotated classes.
Before you go too far down this road, you might want to read this example.
try changing your config to this and report if you are still having the issue...
<bean id="welcomeController" class="com.bamboo.catW3.business.impl.WelcomeController"/>
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/welcome.htm">welcomeController</prop>
</props>
</property>
</bean>
加载中,请稍侯......
