Eureka启动时报错

Unable to start web server; nested exception is org.springframework.boot.web…
原因springBoot版本太高
我用的是2.3.1

 <dependency>
     <groupId>org.springframework.bootgroupId>
     <artifactId>spring-boot-dependenciesartifactId>
     <version>2.3.1.RELEASEversion>
     <type>pomtype>
     <scope>importscope>
 dependency>

改成2.1.2

<dependency>
  <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-dependenciesartifactId>
    <version>2.1.2.RELEASEversion>
    <type>pomtype>
    <scope>importscope>
dependency>

改完之后就可以用了
服了！！！
