Question

当我的应用程序关闭数据丢失时，我想在启动时使用H2。我想在应用程序关闭后保存数据库。

我的application.properties文件

spring.output.ansi.enabled=ALWAYS                    
spring.datasource.url=jdbc:h2:mem:test; 
DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;
spring.datasource.platform=h2
spring.datasource.username = sa
spring.datasource.password =
spring.datasource.driverClassName = org.h2.Driver
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.generate-ddl=true

我的测试用例-

HotelEntity hotelEntity = new HotelEntity(1, "Name", "Password", "MobileNumber", "email");
    hotelDao.save(hotelEntity);
    System.out.println("Hotel Dao--");
    List<HotelEntity> hotelEntities = hotelDao.findAll();
    System.out.println(hotelEntities.size());

它打印列表大小为1，但是当我再次像这样运行测试用例时

List<HotelEntity> hotelEntities = hotelDao.findAll();
System.out.println(hotelEntities.size());

它打印列表大小为0

DB_CLOSE_DELAY = -1; DB_CLOSE_ON_EXIT = FALSE在H2中不起作用
