解决

我的cloud的版本
 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.8.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
但是此处写的版本不对
 <properties>
     <java.version>11</java.version>
     <spring-cloud.version>2020.0.1</spring-cloud.version>
 </properties>
应该改成
 <properties>
     <java.version>1.8</java.version>
     <spring-cloud.version>Greenwich.SR3</spring-cloud.version>
 </properties>
