关闭应用程序后删除Spring JPA数据 [英] Spring JPA data removed after shutdown of application

问题描述

我有一个基于Spring引导的应用程序，它使用HSQL数据库上的JPA存储库.

i have an application thats build on Spring boot, using JPA repositories on HSQL database.

问题是，在应用程序运行时，我创建了一个实体，并将其正确持久存储到数据库中(可以在数据库管理器中看到).但是从eclipse关闭应用程序后，所有数据都将被删除；

Problem is that while application is running, I create an entity,and it's persisted correctly to database(can be seen in database manager). But after application shutdown from eclipse, all data is removed;

保存是这样的

@Service
public class NotificationService {

    @Autowired
    private NotificationRepository notificationRepository;

    public void notifyRefreshArticles(){
        Notification notification = new Notification();
        notification.setCreatedAt(LocalDateTime.now());
        notification.setNotificationSeverity(NotificationSeverity.NORMAL);
        notification.setNotificationType(NotificationType.REFRESH_ARTICLES);

        notificationRepository.save(notification);
    }
}

我非常确定它的配置问题，但是对于Spring Boot，基本上我只有的配置是该配置文件.

I pretty sure its configuration issue,but with spring boot basically only configuration that i have is this configuration file.

spring.datasource.driver-class-name=org.hsqldb.jdbc.JDBCDriver
spring.datasource.url=jdbc:hsqldb:hsql://localhost/rr_app_database
spring.datasource.username=XXXXXX
spring.datasource.password=XXXXXX
spring.datasource.show-sql=true

推荐答案

配置属性中是否有hbm2ddl文本.应该将其设置为update或none，显然您可能具有create-drop.

Do you have hbm2ddl text somewhere in your configuration properties. It should be set to update or none, apparently you might have create-drop.
