可以把你的代码push一下我看看，别用2.0.4.RELEASE，该版本会和视频中的演示差别较大，课程的最后升级到了最新版，你先不急升级。

• 提问者 mtfelix #1

  廖师兄，如下，请帮忙看下：
  [server]
  https://gitlab-demo.com/7095512/myeureka
  [client]
  https://gitlab-demo.com/mtfelix/eurekaclient

• 廖师兄 回复 提问者 mtfelix #2

  你代码里还是2.0.4.RELEASE啊，用我视频中的版本。你的问题不是在
  sprint boot 2.0.0.M3，spring-cloud版本Finchley.M2
  情况下报错的吗

• cloverxixi 回复 廖师兄 #3

  可是现在视频里的版本现在maven仓库里面没有好像，这个问题该怎么解决呢

参见：https://blog.csdn.net/zhongzunfa/article/details/79482147

我在使用2.0.0.M3的时候出现Exception，最后改成2.0.0.RELEASE才解决。

自动关闭的情况，加入了

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-web</artifactId>
</dependency>

之后解决。

供参考

当前最新稳定版本:

Spring Boot 2.2.5.RELEASE
Spring Cloud Hoxton.SR3

POM文件加上如下依赖，依然启动不成，

<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
</dependency>

原因：

全新项目，启动后，Tomcat容器检测不到任何应用内容，启动后会自动退出。导致Eureka client启动失败的现象。

解决办法：

Application启动类主方法中，添加类似如下内容，可解决启动失败问题。服务中有了实际功能后，去掉即可。

while (true){
 Thread.sleep(Integer.MAX_VALUE);
}

我的也是一样的错误，eureka的client启动不起来，client版本跟server一致，都是2.0.5release

看文档添加了web依赖，一切ok

再补充下问题：

我的版本严格按照：

sprint boot 2.0.0.M3，spring-cloud版本Finchley.M2

下面是执行的控制台消息：

  回复下自己最后的解决办法：
  
  spring-boot 2.0.4.RELEASE
  spring-cloud Finchley.SR1
  
  然后在client的pom.xml中增加依赖(实测加不加都ok)：
  
  <dependency>
  			<groupId>org.springframework.boot</groupId>
  			<artifactId>spring-boot-starter-web</artifactId>
  		</dependency>
  
  之前在server的pom.xml中按照doc/QA.md问题1添加了代码（实测加不加都ok）

• 提问者 mtfelix #2

  在client的pom.xml中增加依赖(还是要加的)： <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>
