Spring 应用程序连接到内存中的 H2 数据库而不是基于文件
Spring app connects to in-memory H2 db instead of file based
我正在尝试在磁盘中创建一个本地数据库并连接到它。基本上我想要 jdbc.h2.file，而不是 jdbc.h2.mem。这就是我设置 application.properties.file
的方式
spring.jpa.hibernate.ddl-auto = none
spring.datasource.url:jdbc:h2:file:~/test
spring.datasource.driverClassName:org.h2.Driver
spring.datasource.username:sa
spring.datasource.password:
spring.jpa.show-sql=true
spring.h2.console.path=/h2-console
spring.h2.console.enabled=true
spring.flyway.url:jdbc:h2:file:~/test
spring.flyway.user:sa
spring.flyway.password:
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.flyway.locations=filesystem:./src/main/resources/db/migration

但是，我不希望数据库在内存中。我尝试了网络上针对类似问题的所有建议，尝试了 application.properties 中的不同组合，但这些努力都是徒劳的。似乎内存 (mem) 数据库设置为默认值且无法更改。
这样使用
spring.datasource.url:jdbc:h2:/home/ubuntu/test
您需要传递文件的绝对路径
这实际上是我犯的一个非常愚蠢的错误，将 : 替换为 =
后问题得到解决
