我正在学习Spring 5。我已经将Spring 5MVCHibernate 5示例教程从HSQL转换为PostgreSQL，但它没有起作用。错误是：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'getTransactionManager' defined in com.howtodoinjava.demo.spring.config.HibernateConfig: Invocation of init method failed; nested exception is org.hibernate.service.UnknownUnwrapTypeException: Cannot unwrap to requested type [javax.sql.DataSource]
怎么修？
这是项目的文件和更大的错误消息：

原因是IntelliJ问题，需要重建工件。之后它就起作用了。所以错误消息与我问题中的代码无关。
