Application上加入注解

@EnableFeignClients
public class SurveyActionApiApplication {

    public static void main(String[] args) {
        SpringApplication.run(SurveyActionApiApplication.class, args);
    }
}

服务之间接口调用如下：加入注解@FeignClient

@FeignClient(value = "调用服务名")
@RequestMapping("/open-api/")
public interface XxlJobFeignProxy {

    @RequestMapping("add")
    ReturnT<String> add(info jobInfo);

}
