Spring MVC 3:在不同的控制器中具有相同的@RequestMapping，具有集中式XML URL映射(混合xml/注释方法)

问题描述：

我喜欢将所有映射保留在同一位置，因此我使用XML配置:

I like to keep all my mapping in the same place, so I use XML config:

<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">

    <property name="mappings">
        <value>
            /video/**=videoControllerr
            /blog/**=blogController
        </value>
    </property>
    <property name="alwaysUseFullPath">
        <value>true</value>
    </property>
</bean>

如果我在另一个控制器中创建另一个具有相同名称的请求映射，

If I create a second request mapping with the same name in a different controller,

@Controller
public class BlogController {
    @RequestMapping(value = "/info", method = RequestMethod.GET)
    public String info(@RequestParam("t") String type) {
        // Stuff
    }
}

@Controller
public class VideoController {
    @RequestMapping(value = "/info", method = RequestMethod.GET)
    public String info() {
        // Stuff
    }
}

我得到一个例外:

Caused by: java.lang.IllegalStateException: Cannot map handler 'videoController' to URL path [/info]: There is already handler of type [class com.cyc.cycbiz.controller.BlogController] mapped.

是否可以在不同的控制器中使用相同的请求映射?

Is there a way to use the same request mappings in different controllers?

我想要2个网址为

/video/info.html

/blog/info.html

使用Spring MVC 3.1.1

I' not the only one: https://spring.io/blog/2008/03/24/using-a-hybrid-annotations-xml-approach-for-request-mapping-in-spring-mvc

该应用程序的其余部分运行正常.

The rest of the app works perfectly.

答

只需在Controller级别上放置一个请求映射:

Just put a requestmapping at the level of the Controller also:

@Controller
@RequestMapping("/video")
public class VideoController {
    @RequestMapping(value = "/info", method = RequestMethod.GET)
    public String info() {
        // Stuff
    }
}

@Controller
@RequestMapping("/blog")
public class BlogController {
    @RequestMapping(value = "/info", method = RequestMethod.GET)
    public String info(@RequestParam("t") String type) {
        // Stuff
    }
}
