在没有资源标识的情况下处理RESTful服务请求的理想方式是什么

我有一个使用Spring开发的RESTful服务。该服务尝试使用带有Request方法的标识字符串作为GET来查找资源。

请求模式为：https://api.rest.com/resource/RESOURCEID

为此定义的方法是

@RequestMapping(
            value = "/{RESOURCEID}",
            method = RequestMethod.GET,
            produces = "application/json")
public @ResponseBody String retrieve(
            @PathVariable String resourceID,
            HttpServletRequest request,
            HttpServletResponse response)
                throws AbstractBaseAppException,
                       JsonGenerationException,
                       JsonMappingException,
                       IOException

现在，当我尝试提出类似：https://api.rest.com/resource/的请求时，我会在下面遇到异常：

我不熟悉您正在使用的框架，但有两个问题可能导致问题。

您正在向https://api.rest.com/resource/发出请求，但该方法正在倾听＆＃39;要匹配我期望的匹配/{RESOURCEID}（除非还有其他更好的匹配），这意味着将使用＆＃34; resource＆＃34;作为资源ID传入。

您似乎也没有专门聆听/resource/的方法。

我不明白该错误消息如何链接回到此问题。我建议你查看你看到的那些例外是什么意思以及它们的原因。
