文章标签 无法 注入 bean 大坑 exception threw datasource sqlsessionfactory

本文主要是介绍Bean无法注入，‘sqlSessionFactory‘ threw exception，‘dataSource‘ threw exception大坑，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

原因：

1.配置类中jdbc的配置没错。
2.controller，service，mapper层注解都有
3.启动类上面也有自动扫描的注解
@ComponentScan(basePackages = {"com.XXX"})
4.配置类没有被扫描到：（我遇到的问题！！！）
