若依项目后台启动报错： [网关异常处理]、503

拉取代码启动项目，网关控制台报错：

21:31:59.981 [boundedElastic-7] WARN  o.s.c.l.c.RoundRobinLoadBalancer - [getInstanceResponse,98] - No servers available for service: ruoyi-system
21:31:59.981 [boundedElastic-7] ERROR c.r.g.h.GatewayExceptionHandler - [handle,52] - [网关异常处理]请求路径:/system/dict/data/getPlatform,异常信息:503 SERVICE_UNAVAILABLE "Unable to find instance for ruoyi-system"

发现是服务没起够，用到的没启动就会报这个
