【问题讨论】：
请使用依赖版本号而不是配置的属性名称更新您的 pom.xml。 【参考方案1】：我认为堆栈跟踪可以很好地引导您找到根本原因。
你有一个异常告诉你Error creating bean with name 'entityManagerFactory'
按照堆栈跟踪，您可以看到它是Caused by: Unable to build Hibernate SessionFactory
Caused by: Unable to obtain JDBC Connection
Caused by: Could not create connection to database server.
因此，此时您的问题实际上并不是您无法创建 entityManagerFactory bean，而是您的应用程序无法连接到您的数据库。因此，您只需在application.properties 文件中检查与数据库的连接。我希望这能回答你的问题。
【讨论】：
