休眠ddl-auto =更新不起作用

每當我重新啓動tomcat服務器時，數據庫表中的所有數據都將被刪除。但我想保留數據庫表中的數據。在閱讀了幾篇文章之後，我所瞭解的是ddl-auto應該被設置爲更新。休眠ddl-auto =更新不起作用

在我的春天啓動的應用程序，我有以下設置

security.basic.enabled=false 
server.port=9090 
spring.datasource.url=jdbc:h2:mem:AZ;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE 
spring.datasource.driverClassName=org.h2.Driver 
spring.datasource.username=myuser 
spring.datasource.password=mypassword 
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect 
spring.jpa.generate-ddl=true 
spring.jpa.hibernate.ddl-auto=update 
hibernate.show_sql = true 
hibernate.format_sql = true 
spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

不幸的是，這是因爲它們無法正常工作。表中的所有數據都被刪除。

我真正需要的是保持在數據庫表中的數據，即使重新啓動我的服務器後。

應該由specifing只是那些2個屬性的作用：

測試彈簧引導1.4.1

spring.jpa.hibernate.ddl-auto=update 
spring.datasource.url=jdbc:h2:file:./testdb

。
