数据源Bean不能自动连线以确保安全性，但JPA存储库可以工作

Question

我正在尝试将spring安全性添加到一个简单的spring应用程序中（我想要登录）。

我有一个JPA信息库，可以很好地与我的mysql数据库配合使用，但是在为Spring Security添加配置时，似乎找不到数据源bean。

错误

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.apache.tomcat.jdbc.pool.DataSource] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
