Java Spring MVC将URL映射到控制器的问题

我正在使用SpringMVC开发一个web应用程序

我有两个控制器：QuestionController和TodoController——它们都扩展了MultiActionController，并且都定义了

list（）

方法

我在my web.xml中为dispatcher定义了映射，如下所示：

<servlet-mapping>
    <servlet-name>app</servlet-name>
    <url-pattern>/todo/*</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>app</servlet-name>
    <url-pattern>/question/*</url-pattern>
</servlet-mapping>  

<bean id="handlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">        
    <property name="mappings">
        <props>
            <prop key="/todo/**">todoController</prop>
            <prop key="/question/**">questionController</prop>
        </props>
    </property>

2011-08-08 15:23:38,098 [http-8080-3] DEBUG org.springframework.web.servlet.DispatcherServlet - DispatcherServlet with name 'app' determining Last-Modified value for [/app/todo/list]

正如您所看到的-出于某种原因，尽管URL与TodoController的映射相匹配，但现在仍选择了问题控制器

有什么想法吗

更新

这两个控制器的定义如下：

<servlet-mapping>
    <servlet-name>app</servlet-name>
    <url-pattern>/todo/*</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>app</servlet-name>
    <url-pattern>/question/*</url-pattern>
</servlet-mapping>  

<bean id="handlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">        
    <property name="mappings">
        <props>
            <prop key="/todo/**">todoController</prop>
            <prop key="/question/**">questionController</prop>
        </props>
    </property>

QuestionController.java

@Controller
public class QuestionController extends MultiActionController implements InitializingBean 
{

    @RequestMapping("/list")
    public ModelAndView list(HttpServletRequest request, HttpServletResponse response) throws Exception{
        //Display List view for questions
    }

    @RequestMapping("/detail/{questionId}")
    public ModelAndView detail(@PathVariable("questionId") long questionId, HttpServletRequest request, HttpServletResponse response) throws Exception{
        //Display Detailed Question View for questionId...
    }
}

public class TodoController extends MultiActionController implements InitializingBean 
{

    @Transactional
    public ModelAndView list(HttpServletRequest request, HttpServletResponse response) throws Exception{
        //Display list of Todos
    }

}

ToDoController.java

@Controller
public class QuestionController extends MultiActionController implements InitializingBean 
{

    @RequestMapping("/list")
    public ModelAndView list(HttpServletRequest request, HttpServletResponse response) throws Exception{
        //Display List view for questions
    }

    @RequestMapping("/detail/{questionId}")
    public ModelAndView detail(@PathVariable("questionId") long questionId, HttpServletRequest request, HttpServletResponse response) throws Exception{
        //Display Detailed Question View for questionId...
    }
}

public class TodoController extends MultiActionController implements InitializingBean 
{

    @Transactional
    public ModelAndView list(HttpServletRequest request, HttpServletResponse response) throws Exception{
        //Display list of Todos
    }

}

如您所见，我只在QuestionController上添加了注释，而不是ToDo控制器。我也没有在注释中再次明确定义到问题控制器的URL映射（我知道我可以将

@RequestMapping（“/Question”）

在类级别-但由于这已经在配置中定义，我没有在这里添加它。此外，如果我在这里也定义了它，那么我会得到一个

ResourceNotFound

错误，但是如果我导航到

/question/question/list

，那么它会正确加载）

为什么使用旧配置，而不是注释？两个控制器的控制器代码是什么样子的？@Bozho，这只是个人偏好-我更喜欢有一个中央配置来定义我的控制器类和关联的URL映射，因为我个人觉得它更容易获取，而不必通过类来查找所有控制器及其映射。@nicholas.hauschild-更新了控制器的原始问题。@BozhoSpringSource工具套件Eclipse插件添加了一个名为RequestMappings的视图，该视图在一个位置显示所有映射，当然，它们是通过注释定义的。
