spring cloud關於feign client的調用對象列表參數、設置header參數、多環境動態參數試配

spring cloud關於feign client的調用

     1、有些場景接口參數需要傳對象列表參數

     2、有些場景接口設置設置權限等約定header參數

     3、有些場景雖然用的是feign調用，但並不會走eureka，比如調用外網www.baidu.com等的接口，需要進行多環境試配

示例如下：

      server controller端：

@RequestMapping(value = "bbbb", method = {RequestMethod.GET, RequestMethod.POST}, produces = "application/json;charset=UTF-8")
RespData<List<XxxxVo>> getConverseShortUrlForRobotBatch( @RequestParam("vId") Long vId,
  @RequestBody List<XxxxVo> xxxxVoList,
 HttpServletRequest httpServletRequest){
 ...........
 List<XxxxVo> resultVoList = new ArrayList<XxxxVo>();
 if(StringUtils.isNotEmpty(httpServletRequest.getHeader("token")) && httpServletRequest.getHeader("token").equals("xxxxx")){
..................
 }
}

     client端（其中xxxx.business.service.domain，可以在properties配置文件里配置）：

@FeignClient(name = "xxxxx-business-service", url = "http://${xxxx.business.service.domain}")
public interface ImptClient {
 @RequestMapping(value = "/xxx/xxx/bbbbb", method = {RequestMethod.POST}, produces = "application/json;charset=UTF-8",headers = {"token=xxxxx"})
 RespData<List<XxxxVo>> bbbbb(@RequestParam("vId") Long vId,@RequestBody List<XxxxVo> xxxxVoList);
}
