java.lang.IllegalStateException: Service id not legal hostname

springcloud注册服务后两个服务互相调用抛出错误：java.lang.IllegalStateException: Service id not legal hostname ******
主要原因是注册的服务名字中不能有下划线比如 abc_fssa
改为abc-fssa即可解决

application.yml

spring:
  application:
    name:  abc_fssa

改为

spring:
  application:
    name:  abc-fssa
