如何在两个应用程序之间共享h2数据库?

我已经尝试了一段时间,我有一个管理应用程序和主应用程序

            <img class="image-responsive shelf-book" th:src="#{adminPath}+@{/image/book/}+${book.id}+'.png'" width="100px" />

所以这里的管理员路径是管理员的URL,但由于他们不共享同一个数据库,我无法在我的主应用程序中查看书籍

我在想spring云服务器,但没用,有什么建议吗?

当我添加这个时

jdbc.driverClassName=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:test:MODE=MySQL;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE
spring.datasource.username=sa
spring.datasource.password=

我犯了这个错误

Caused by: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.h2.jdbc.JdbcSQLException: Feature not supported: "autoServerMode && inMemory" [50100-196]

I added this below to both application and one app is running but the show this error
jdbc.driverClassName=org.h2.Driver
spring.datasource.url=jdbc:h2:~/test;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE 
spring.datasource.username=sa
spring.datasource.password=
