> SpringCloud Eureka报错启动不了大多数是因为依赖问题，springboot的版本和springcloud的版本需要进行匹配，可以参考[SpringCloud官网][SpringCloud]配置，千万不要自己瞎配。

不然可能就会出现以下各种报错：

我们可以看下官方给出的示例：

<repositories>
        <repository>
            <id>spring-milestones</id>
            <name>Spring Milestones</name>
            <url>https://repo.spring.io/milestone</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>
    
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>2020.0.0-M5</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
            
        </dependency>
    </dependencies>

然后我们看官网说的，该版本它依赖于SpringBoot的2.4.0版本

最后给出我的依赖配置如下：
