Question

我在spring-mvc控制器中有这些方法与这个URL冲突：http://127.0.0.1:7001/deviceApp/device/en/17624

java.lang.IllegalStateException: Ambiguous handler methods mapped for HTTP path 'http://127.0.0.1:7001/deviceApp/device/en/17624':

方法：

@RequestMapping(value = { "/device/{localeParam}/{itemId}", "/device/{localeParam}/{itemId}/{seoURLapplication}"},  method = { RequestMethod.GET })
    private String showDeviceDetailsAndSeoURLapplication(@PathVariable String itemId,
                                                          @PathVariable String localeParam,
                                                          @PathVariable String seoURLapplication,
                                                          HttpServletResponse response,                                   
                                                          HttpServletRequest request, Model model, Locale locale) {

        Item item = deviceService.getItem   (Long.parseLong(itemId), "P");

        changeLocale (localeParam, request, response);

        addItemToModel (item, locale,  model);

        return DEVICE_DETAIL_VIEW;
    }


    @RequestMapping(value = { "/device/{localeParam}/{itemId}", "/device/{localeParam}/{itemId}/"},  method = { RequestMethod.GET, RequestMethod.POST })
    private String showDeviceDetails(@PathVariable String itemId,
                                      @PathVariable String localeParam,
                                      @ModelAttribute("searchForm") final SearchForm searchForm,
                                      HttpServletResponse response,                                   
                                      HttpServletRequest request, Model model, Locale locale) {


        Item item = deviceService.getItem   (Long.parseLong(itemId), "P");

        return DEVICE_DETAIL_VIEW;
    }

web.xml上的

<servlet-mapping>
        <servlet-name>deviceWeb</servlet-name>
        <url-pattern>/device</url-pattern>             
        <url-pattern>/device/*</url-pattern>
        <url-pattern>/device/*/</url-pattern>         
        <url-pattern>/device/*/*</url-pattern>
       <url-pattern>/device/*/*/*</url-pattern>
</servlet-mapping>

这两种方法实际上是不明确的，根据您在签名中预期的路径变量，您应该删除"/device/{localeParam}/{itemId}"

中showDeviceDetailsAndSeoURLapplication的映射

另外，servlet映射应该匹配所有请求

<servlet-mapping>
        <servlet-name>deviceWeb</servlet-name>
        <url-pattern>/</url-pattern>
</servlet-mapping>

，或者

<servlet-mapping>
        <servlet-name>deviceWeb</servlet-name>
        <url-pattern>/device</url-pattern>             
</servlet-mapping>

在这种情况下，您应该从控制器映射路径中删除/device

在spring-mvc App中为HTTP路径映射的不明确的处理程序方法
