使用FeignClient进行微服务交互方式(微服务接口互相调用)

  public String getSettingValue(String name) {
       Map<String, Object> map = (Map) settingClient.getByName(name).getData();
       return (String) map.get("value");
  }

@FeignClient(value="qiang-admin")
public interface SettingClient {
    @RequestMapping(value="/setting/getSetting/{name}",method = RequestMethod.GET)
    public ReturnMsg getByName(@PathVariable("name") String name);
}

    @RequestMapping(value="/getSetting/{name}",method = RequestMethod.GET)
    public ReturnMsg getByName(@PathVariable String name){
        Setting condition = new Setting();
        condition.setName(name);
        ReturnMsg returnMsg = new ReturnMsg<>();
        Setting setting = settingService.findByCondition(condition);
        returnMsg.setCode(ReturnIntCode.SUCCESSS_CODE);
        returnMsg.setData(setting);
        return returnMsg;
    }

@FeignClient("target-servername")
  public interface FeignClient {
       @RequestMapping(value = "/simple/{id}", method =RequestMethod.GET)
 public Object findById(@PathVariable("id") Long id);
 ...
}

@FeignClient("target-servername")
public interface FeignClient {
 @RequestMapping(value = "/simple/{id}", method = RequestMethod.GET)
 public Object findById(@PathVariable("id") Long id);
 ...
}

@FeignClient("target-servername")
public interface UserFeignClient {
 @RequestMapping(value = "/query-by", method = RequestMethod.GET)
 public Object queryBy(@RequestParam("id")Long id, @RequestParam("username")String username);
}
