我已经实现了One演示项目，在这里我列出了我的项目所使用的依赖项。
- 弹簧-2.0.1
- spring-data-jpa-2.06
- 弹簧芯-5.0.5
- 休眠-核心-5.4.1
- postgresql-42.2.2
我在application.yml和MasterDatabaseConfig.java文件中使用了带有SQL配置的Microsoft SQL server，它运行良好，能够从SQL数据库中获得结果。
当我将数据库从SQL server更改为PostgreSQL时，我在会话工厂中没有得到Connection，它在控制台中引发了错误。这里我已经给出了强制性的配置文件，请帮助我解决这个问题。
