使用ControllerClassNameHandlerMapping实现SpringMVC

做为spring的新手，很愿意尝试这样的优秀框架，但最近做项目时，总是碰到恼人的问题
为了做到零配置用到了ControllerClassNameHandlerMapping，访问预先设定好的url，总会出现No mapping for [/springT/registration.hr] in DispatcherServlet with name 'Dispatcher'

3

<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>
4

5

<bean id="registrationController" class="com.RegistrationController"/>
6

看似Controller都已经注入到Spring中：

2010-07-17 15:48:23 Registering Controller 'registrationController' as handler for URL path [/registration]

2010-07-17 15:48:23 Creating shared instance of singleton bean 'registrationController'

2010-07-17 15:48:23 Creating instance of bean 'registrationController'

2010-07-17 15:48:23 Eagerly caching bean 'registrationController' to allow for resolving potential circular references

2010-07-17 15:48:23 Finished creating instance of bean 'registrationController'

2010-07-17 15:48:23 Mapped URL path [/registration] onto handler [com.RegistrationController@1a2af25]

2010-07-17 15:48:23 Registering Controller 'userController' as handler for URL path [/user]

访问debug错误信息如下：

2010-07-17 15:49:50 Looking up handler for [/registration.hr]

2010-07-17 15:49:50 No mapping for [/springT/registration.hr] in DispatcherServlet with name 'Dispatcher'

通过多方努力，同事的帮助下，发现是缺包spring-web.jar、spring-webmvc.jar，也真搞笑，缺两个包居然没有错误，特此记录

2010-07-17 16:55:00 Rejected bean name 'org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping#0': no URL paths identified

2010-07-17 16:55:00 Creating shared instance of singleton bean 'registrationController'

2010-07-17 16:55:00 Creating instance of bean 'registrationController'

2010-07-17 16:55:00 Eagerly caching bean 'registrationController' to allow for resolving potential circular references
5

2010-07-17 16:55:00 Finished creating instance of bean 'registrationController'

2010-07-17 16:55:00 Mapped URL path [/registration*] onto handler [com.RegistrationController@4dc957]
7

2010-07-17 16:55:00 Mapped URL path [/user*] onto handler [userController]

中间最大的差异就是
正确：
Mapped URL path [/registration*] onto handler [com.RegistrationController@4dc957]
错误：
Mapped URL path [/registration] onto handler [com.RegistrationController@1a2af25
