做為spring的新手，很愿意嘗試這樣的優(yōu)秀框架，但最近做項目時，總是碰到惱人的問題
為了做到零配置用到了ControllerClassNameHandlerMapping，訪問預(yù)先設(shè)定好的url，總會出現(xiàn)No?mapping?for?[/springT/registration.hr]?in?DispatcherServlet?with?name?'Dispatcher'

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

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

?????<bean?id="userController"?class="com.UserController"?scope="request"/>

看似Controller都已經(jīng)注入到Spring中：

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]

訪問debug錯誤信息如下：

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

通過多方努力，同事的幫助下，發(fā)現(xiàn)是缺包spring-web.jar、spring-webmvc.jar，也真搞笑，缺兩個包居然沒有錯誤，特此記錄

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

中間最大的差異就是
正確：
???Mapped?URL?path?[/registration*]?onto?handler?[com.RegistrationController@4dc957]
錯誤：
???Mapped?URL?path?[/registration]?onto?handler?[com.RegistrationController@1a2af25
