我有一个Spring应用程序，在其中我这样声明了我的班级：

@Controller
@RequestMapping(value = "/rest/api/datasources/", produces = MediaType.APPLICATION_JSON_VALUE, method=RequestMethod.GET)
public class MetadataServiceController {
    //Two separate methods:
    @RequestMapping(value="{datasourceName}")
    public Object getLatestApiMetadata(@PathVariable String datasource, 
           @RequestParam (required = false)  String datasourceNum,
           @RequestParam (defaultValue = "true")  String dataFields, 
           @RequestParam ( required=false, defaultValue = "api")  String visibility){
      ... //Implementation here
    }

    @RequestMapping(value="{apiVersion}")
    public @ResponseBody List<DataSource> getAllMetadata(
        @RequestHeader(value="sub-version", required=false, defaultValue="0.0") String minorVer,
        @PathVariable String restApiVersion,
        @RequestParam(required = false) String datasourceNum,
        @RequestParam(defaultValue = "all") String visibility)
        throws ObjectNotFoundException {
    ... //Implementation here
    }

}

但是，当我尝试到达这些其余端点之一时，出现一条错误消息：java.lang.IllegalStateException: Ambiguous handler methods mapped for HTTP path并且将这两种方法指定为问题。我的印象是，如果更改请求参数，Spring不会通过这篇文章抱怨它们相同：http : //www.coderanch.com/t/598675/Spring/handling-HTTP-
Request-parameters
但显然它仍然如此。有人会对如何解决这个问题有任何建议吗？谢谢！
