上网也找了好多资料，错误原因是springcloud的版本与springboot版本不一致造成的。
springcloud与springboot的版本对应关系请参考 https://start.spring.io/actuator/info
我项目中springcloud版本是Finchley.SR2，springboot ： 2.1.0.RELEASE
由于我这里使用的是springcloud ： Finchley.SR2，该版本对应的springboot版本是Spring Boot >=2.0.3.RELEASE and <2.0.999.BUILD-SNAPSHOT。所以我们将springboot降级版本即可。
没试过springcloud 升级能不能解决问题，有时间可以去试一下。
