此bug一般是因为Spring Boot版本与Spring Cloud版本不匹配导致,我搭建Eureka环境时用的springBoot版本是 2.0.3.RELEASE,springCloud版本是 Greenwich.SR4

以下为错误版本冲突示范,切勿CV

<parent>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
      <version>2.0.3.RELEASE</version>
</parent>
<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.SR4</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
</dependencyManagement>

 

解决方法是我把Spring Boot版本改为2.1.3.RELEASE就可以啦!

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.3.RELEASE</version>
</parent>
