问题：
Springboot:：Hibernate:：无法构建Hibernate SessionFactory
尹善
我正在使用Hibernate和spring boot。我注意到，如果我从包中包含注释@CreationTimestamp和@UpdateTimestamp
org.hibernate.annotations.CreationTimestamp;
org.hibernate.annotations.UpdateTimestamp;
并尝试运行spring启动应用程序。我的应用程序启动失败，出现以下错误。

我相信这是因为我引入了一些与hibernate相关的类，这些类导致了这个问题。有人能告诉我怎么了吗？

在这种情况下，似乎没有检测到包。你能试着用这个吗？
@Column(name="CREATED_DATE", updatable=false, nullable=false)
@CreationTimestamp
private java.sql.Timestamp createdDate;
编辑：
移除@Temporal。
或者保留Temporal，把包放在上面，就像：
@Column(name="CREATED_DATE", updatable=false, nullable=false)
@CreationTimestamp
@Temporal(TemporalType.TIMESTAMP)
private java.util.Calendar createdDate;

在我的例子中，我和org都面临着同样的错误。冬眠cfg。尝试编译以下Jpa文件时出现NotYetImplementedException：
>
AlertJpaMode.java：
@Entity
@Table(name = "alerts")
@IdClass(AlertId.class)
public class AlertJpaModel implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
@Id
@Column(nullable = false)
@CreationTimestamp
private Instant timestamp;
// more fields here and constructors + getters/setters
}
AlertId.java：
public class AlertId implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private Instant timestamp;
// more fields here and constructors + getters/setters
}
我只是把creationtimestap放在AlertId中。java而不是在AlertJpaMode中。java如下所示：
>
AlertJpaMode.java：
@Entity
@Table(name = "alerts")
@IdClass(AlertId.class)
public class AlertJpaModel implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
@Id
@Column(nullable = false)
private Instant timestamp;
// more fields here and constructors + getters/setters
}
AlertId.java：
public class AlertId implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
@CreationTimestamp
private Instant timestamp;
// more fields here and constructors + getters/setters
}
...它成功了。

我正在使用Arquillian、JBoss、JPA/Hibernate、H2 DB和Maven运行测试。在我的测试persistence.xml文件中，我有： 目前，我有一个User类通过Hibernate注释映射到“users”表。 一切都快开始了。问题是Hibernate正在尝试执行： 但是模式“my_schema”不存在，所以它失败了（毕竟我是在运行内存中的数据库）。 我如何进入Hibern

有些人在不同的问题上提到，如果数据库在执行之前不存在，就会发生这个错误，所以我手动创建了数据库，但仍然会出现这个错误。 编辑：这里是应用程序的跟踪日志。由于文本太多，我将其上传为文件:https://ufile.io/zuk69

我正在使用Spring Boot，我将向您解释我所进行的过程，然后我将为您暴露我的问题: 我正在使用的数据库是postgres：因为我有一个包含多个表的富数据库，所以我应用了hibernate反向工程来生成hole实体，直到这一步一切都很棒！ 问题，在运行项目时，它就像是spring-data JPA和hibernate之间的混淆！ ps:在项目开始工作之前，我用一张桌子做了一些实验，它工作得很好
