問題描述
今天搭建spring cloud項目，啓動Client客戶端的時候老是啓動后就自動停了，啓動信息如下：
=======================================================以下爲啓動信息

===================================================以上為啓動信息
然後在百度中找到各種帖子，主要是說，要引入web依賴，然後檢查我的pom文件，發現我是引入了的
<!-- springboot整合web组件 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>然後是各種鷄頭白臉（小弟是菜鳥，大佬勿噴）
無意間在idea發現這麽一條信息：
解決方法：
進入我的maven倉庫找了下，這個包是有的，但是有多個版本，於是就加了版本號：
<!-- springboot整合web组件 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.2.1.RELEASE</version>
</dependency>奇跡發生了，啓動成功了！！！
也就是說，如果出現這個問題，就需要在pom文件中整合web組件，并且不要忘記版本號。
以上一句才是關鍵，其他的。。。。。。我只是水一水！
