我正在为我的应用程序使用 spring、hibernate、mysql，我正在尝试使用 h2 来测试我的存储库和服务，但是我收到一个错误，我已经好几天没有解决了。
这是应用程序属性：
`spring.datasource.url=jdbc:mysql://${MYSQL_HOST:localhost}:3306/daskalos
#---enter your username and password------------------
spring.datasource.username = root
spring.datasource.password = admin
#-----------------------------------------------------
spring.jpa.defer-datasource-initialization = true
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation = true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL8Dialect
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.default_schema=daskalos
#-----Hibernate ddl auto (create, create-drop, validate, update)----------------
spring.jpa.hibernate.ddl-auto = update
#-------------------------------------------------------------------------------
server.port=8080`
这是我用于测试的测试属性：
`spring.datasource.driverClassName=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DATABASE_TO_LOWER=TRUE;DB_CLOSE_ON_EXIT=FALSE;MODE=MySQL
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL8Dialect
spring.datasource.username=sa
spring.datasource.password=
spring.jpa.hibernate.ddl-auto=create-drop
spring.h2.console.enabled=false
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
spring.jpa.generate-ddl=true
spring.jpa.defer-datasource-initialization=true`
这是我的测试课：
