ControllerClassNameHandlerMapping @Controller

这里也提到这个问题

http://forum.springsource.org/showthread.php?p=151750

Allow ControllerClassNameHandlerMapping and @Controller to work together

似乎在Spring mvc 2.5.4里面有一个 bug


就是当你实现一个controller 时候，使用 COC原则自动映射。无法映射到对应的默认方法 handleRequestInternal


这个问题在 spring 官方论坛的mvc版块里面也提到了这个问题。还是 appfuse Matt Raible 提交的。


具体的一个解决方式是 Keith Donald 提出的。看看他的配置文件就知道了。



Matt Raible 看了以后说


Thanks Keith - your webmvc-config.xml seems to contain the magic sauce that makes this work as expected.

In Matt's example the index method on HomeController would be mapped to the URL /home/index by the 2.5.3 convention, which I imagine isn't what he wants.
Just to provide more usage examples of this feature, here is an example in the Spring MVC + Web Flow reference application "booking-mvc". You can see the code on-line here: https://springframework.svn.sourceforge.net/svnroot/springframework/spring-webflow/trunk/spring-webflow-samples/booking-mvc

Specifically see:

@Controller code: https://springframework.svn.sourceforge.net/svnroot/springframework/spring-webflow/trunk/spring-webflow-samples/booking-mvc/src/main/java/org/springframework/webflow/samples/booking/HotelsController.java

Config:
https://springframework.svn.sourceforge.net/svnroot/springframework/spring-webflow/trunk/spring-webflow-samples/booking-mvc/src/main/webapp/WEB-INF/config/webmvc-config.xml

The URls mapped by convention are then:

/hotels/index
/hotels/search
/hotels/show
/hotels/deleteBooking

But no, /hotels doesn't mapped to to the index method by default... not in 2.5.3 anyway. Is this the convention you want? Perhaps we could employ a convention to map the root controller URL e.g. /home to a "home" method on the HomeController...
