Spring 3.2.4 Servlet配置错误 - 控制器没有捕获URL(Spring 3.2.4 Servlet Configuration Error — Controller not catching URL)

我正在尝试重构一个当前使用CXFServlet的应用程序,以便为REST api请求使用调度程序servlet。

我在web.xml中创建了一个servlet和servlet映射:

<servlet>
    <servlet-name>api</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>3</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>api</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

然后我创建了一个api-servlet.xml:

<context:component-scan base-package="org.myapp.api"></context:component-scan>
<context:annotation-config/>
<tx:annotation-driven/>
<mvc:annotation-driven />

最后,我在相应的包中创建了一个新的控制器:

@Controller("eventsController")
@RequestMapping("/api/events")
public class EventsController {

    private static final Logger LOGGER = LogUtils.getLogger();

    @GET
    @Path("/{eventId}")
    public EventDto getEvent(@PathParam("eventId") Long eventId) {
        //do controller stuff
    }

    @GET
    @Path("/")
    public List<EventDto> getEvents() {
        //do controller stuff
    }
}

应用程序启动正常,我初始化servlet并找到eventsController bean,我没有错误。 在尝试命中其余端点时,我收到一个错误:

Apr 17, 2015 11:02:27 AM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/api/events/42] in DispatcherServlet with name 'api'

我已经查看了其他几个有此错误的帖子,但还没有找到解决方案。

谢谢。


I'm trying to refactor an app that is currently using a CXFServlet to use a dispatcher servlet for REST api requests.

I created a servlet and servlet mapping in web.xml:

<servlet>
    <servlet-name>api</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>3</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>api</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

I then created a api-servlet.xml with:

<context:component-scan base-package="org.myapp.api"></context:component-scan>
<context:annotation-config/>
<tx:annotation-driven/>
<mvc:annotation-driven />

Finally I created a new controller in the appropriate package:

@Controller("eventsController")
@RequestMapping("/api/events")
public class EventsController {

    private static final Logger LOGGER = LogUtils.getLogger();

    @GET
    @Path("/{eventId}")
    public EventDto getEvent(@PathParam("eventId") Long eventId) {
        //do controller stuff
    }

    @GET
    @Path("/")
    public List<EventDto> getEvents() {
        //do controller stuff
    }
}

The app starts up fine, I the servlet is initialized and the eventsController bean is found and I get no errors. On trying to hit the rest endpoint though, I get a error:

Apr 17, 2015 11:02:27 AM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/api/events/42] in DispatcherServlet with name 'api'

I've looked through several other posts with this error and haven't found a solution yet.

Thank you.

最满意答案

handle()方法中,您可以这样做

Object row = getTableView.getItems().get(getIndex());

如果在类型参数中使用更多特定类型,则可以使用更具体的类型替换Object


In the handle() method you can do

Object row = getTableView.getItems().get(getIndex());

You can replace Object with a more specific type if you use more specific types throughout in the type parameters.
