Postgresql 如何禁用嵌入式数据库Spring引导Spring数据jpa

我无法读取/写入本地设置的Postgresql数据库（9.4）。我的应用程序始终使用嵌入式数据库。当我在数据库上执行一些select查询时，没有插入任何数据。你能检查一下我的档案吗

我正在使用SpringBoot和SpringDataJPA

文件：application.properties

这个周末我找到了解决办法

我的数据库中有一些带有大写字母的表“Customer”和“Product”，但我的应用程序为我创建了表“Customer”和“Product”。所以，它没有提取我的数据

我在pom中看不到对嵌入式数据库（H2、HSQLDB等）的依赖关系。您如何确定您的应用程序正在使用一个？
