@RequestMapping(value=“v1/firewall/policy”是什么意思/{区域ID:。*\\你要做什么?

我很难理解下面的Rest端点在做什么——更具体地说,就是 value = "v1/firewall/policy/{zoneId:.*\\D+.*}" 零件:

   @RequestMapping(
        method = {RequestMethod.PUT, RequestMethod.POST},
        value = "/v1/firewall/policy/{zoneId:.*\\D+.*}",
        headers = "Accept=application/json"
)
public ResponseEntity post_policy(@RequestBody InformationPolicy informationPolicy,
                                  @RequestHeader("deployment-id") String deploymentId) {

    someService.process(policyInformation, deploymentId);

    return createResponse(new RestStatus(HttpStatus.OK));

}

"{zoneId:.*\\D+.*}" ,我以前从没见过这种格式 (zoneId:.*\\D+.*) --那是什么鬼东西?
