我通过清理maven repository（m2 repository）修复了它。

如果您错误地将@ComponentScan放入默认包中，是吗？另外，什么版本的Java？添加显示您的

@springboot应用程序
类和所有
@ComponentScan
用法的代码！j'aiéditéma question et j'ai ajoutéla class main java version=1.8为什么在
pom.xml
中依赖于
spring jdbc
？混合使用不兼容版本的Spring jar文件可能会导致错误，就像您得到的一样。@Jesper我删除了那个依赖项，但仍然有相同的错误。您是如何清除它的？clean maven存储库的含义是什么？你把它完全删除了吗？
