我试图启动一个Spring Boot应用程序，使用一个简单的类JPA映射和H2数据库，但每次我尝试启动应用程序时，我在同一列有相同的类错误。
类错误:

出现错误的列是一个已经映射的表:

我的H2配置:

# ===== JPA Configuration =====

spring.datasource.url=jdbc:h2:file:~/time-control
spring.datasource.username=sa
spring.datasource.password=

我尝试手动导入类，但它们如何来自同一个包，java说导入从未使用过。
有人已经通过这个或可以帮助我这个请吗?
缺少的是映射类之间的关系，因此映射之后，Spring Boot可以很好地编译。
