我想将我的数据库从spring连接到h2控制台，但当我这样做时，它不会显示其中的任何表，我尝试了stackoverflow和google的所有解决方案，但似乎没有任何帮助这是我的application.properties文件：

spring.jpa.show-sql=true
spring.h2.console.enabled=true
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.url=jdbc:h2:mem:testdb

如果data.sql和存储在resources中，则为我的数据库的名称
pom.xml的内容：
