本文介绍了解决Spring Boot启动时@ComponentScan默认包警告的方法。通常原因是启动类放置位置不当，解决办法是在src下创建特定包（如controlcenter），并将启动类移入此包中。

* WARNING * : Your ApplicationContext is unlikely to start due to a @ComponentScan of the default package.

  1. 如何解决
    既然他说该类不能从组件的默认包启动，那就给他建立一个包好了。

// 一般发出这个警告的原因是你把启动类直接放在的src目录下面。
// 你需要在src目录下面再建一个包，比如controlcenter，然后把启动类放到controlcenter下面。

我们查看入口函数，并没有ComponentScan标签，所以猜测为默认入口函数位置与默认扫描位置没有对应上导致。（由于默认包的@ComponentScan，您的ApplicationContext不太可能启动）
