我用的是:

• Spring启动 2.0.4.发布
• Spring数据-JPA 2.0.9.发布
• Hibernate核心 5.2.17.最终版
• hibernate-jpa-2.1-api 1.0.0.final
• Postgres JDBC 驱动程序 42.2.9

我有以下实体：

@Entity
@EntityListeners(AuditingEntityListener.class)
public class MyEntity implements Serializable
{
    @Column(nullable = false, updatable = false)
    @CreatedDate
    private LocalDateTime createdDate;

    @Column(nullable = false)
    @LastModifiedDate
    private LocalDateTime lastModifiedDate;

    public LocalDateTime getCreatedDate()
    {
        return createdDate;
    }

    public LocalDateTime getLastModifiedDate()
    {
        return lastModifiedDate;
    }
}

以及在应用程序.yaml 中设置的以下属性：

spring:
  jpa:
    properties:
      hibernate:
        jdbc:
          time_zone: UTC

不管JVM时区/默认时区是什么，我都希望以UTC格式保存和返回时间戳。

出于测试目的，我将应用程序代码的时区设置为美国/夏威夷：

TimeZone.setDefault(TimeZone.getTimeZone("US/Hawaii"));

当我保存一个实体时，它会用UTC时间戳正确地写入数据库：

[16:43:04.636Z #4c5.042 TRACE -            -   ] o.h.t.d.sql.BasicBinder: binding parameter [1] as [TIMESTAMP] - [2020-03-02T06:43:04.581]
[16:43:04.645Z #4c5.042 TRACE -            -   ] o.h.t.d.sql.BasicBinder: binding parameter [2] as [TIMESTAMP] - [2020-03-02T06:43:04.581]

然而，当我再次读取它时，它返回的是我在应用程序代码中设置的默认时区:< code >美国/夏威夷，而不是< code>UTC:

[16:43:04.692Z #4c5.043 TRACE -            -   ] o.h.t.d.sql.BasicExtractor: extracted value ([createdD4_0_0_] : [TIMESTAMP]) - [2020-03-02T06:43:04.581]

我试过添加serverTimeZone=UTC

任何帮助都非常感谢。

使现代化

根据@midhunmathew的回答，我发现控制应用程序代码中的日期就足以解决这个问题（也从application.yaml中删除time_zone属性）：

myEntity.setCreatedDate(LocalDateTime.ofInstant(Instant.now(), ZoneOffset.UTC))

public void setCreatedDate(LocalDateTime createdAt) 
{ 
  this.createdAt = createdAt; 
}

现在，当写入数据库时，日期被“绑定”并作为< code>UTC插入(与原始帖子相比，在原始帖子中，日期被“绑定”为< code>US\Hawaii，但作为< code>UTC插入):

[10:10:21.475Z #065.042 TRACE -            -   ] o.h.t.d.sql.BasicBinder: binding parameter [1] as [TIMESTAMP] - [2020-03-03T10:10:17.400]
[10:10:21.476Z #065.042 TRACE -            -   ] o.h.t.d.sql.BasicBinder: binding parameter [2] as [TIMESTAMP] - [2020-03-03T10:10:17.400]
[HikariProxyPreparedStatement@860888944 wrapping insert into myentity(createdDate, lastModifiedDate) values ('2020-03-03 10:10:17.4-10', '2020-03-03 10:10:17.4-10')]
[10:10:21.479Z #065.042 TRACE -            -   ] 

并且从数据库读取实体时，日期不再读取为US/夏威夷，而是读取为UTC：

[10:10:24.527Z #065.043 TRACE -            -   ] o.h.t.d.sql.BasicExtractor: extracted value ([createdD4_0_0_] : [TIMESTAMP]) - [2020-03-03T10:10:17.400]
[10:10:24.527Z #065.043 TRACE -            -   ] o.h.t.d.sql.BasicExtractor: extracted value ([lastModi5_0_0_] : [TIMESTAMP]) - [2020-03-03T10:10:17.400]
