希望我已经提供了查看我正在做什么所需的所有配置

提前感谢您的帮助！我是一名经验丰富的Java程序员，但对Spring/Hibernate还不熟悉

驱动程序名称是

org.postgresql.driver

，而不是

com.postgresql.driver

我希望您不打算在实时环境中使用

org.springframework.jdbc.datasource.DriverManagerDataSource

。它对于测试或独立环境非常有用。对于在Tomcat上运行的应用程序，您应该查看一个支持连接池的应用程序

非常感谢你的帮助！我发誓我看了好几遍，把它和罐子比较了一下，我没有注意到。
