我无法理解这是什么意思。我已经在 StackOverflow 中搜索过错误。有一些关于 HikariPool 的问题，但没有一个对我有用。

我的 application.properties 如下，

spring.datasource.url=jdbc:postgresql://localhost/test2
spring.datasource.username=postgres
spring.datasource.password=root
spring.jpa.generate-ddl=true

我的 pom.xml 依赖项是，

欢迎来到 Java 世界。尝试理解错误，因为大多数时候 Error 会自言自语出什么问题。在您的案例中，如下图所示，您可以清楚地看到它提到
数据库 test2 不存在。
