问题描述

使用休眠/启用，如何:

Using Hibernate/Envers, how to:

1. 保存Hibernate Envers修订版信息的UTC(而不是本地)时间戳吗?
2. 是否将时间戳记作为LocalDateTime(Java 8)?

推荐答案

1)从修订版侦听器中，调用修订版的fixTimezone方法，如下所示.

1) From the revision listener, call the fixTimezone method of the revision, as shown below.

2)要使用LocalDateTime的形式，请使用getRevisionDate方法，如下所示.

2) To get it as LocalDateTime use the getRevisionDate method, as shown below.

public class MyRevisionListener
    implements RevisionListener {

    @Override
    public void newRevision(Object revisionEntity) {
        MyRevision revision = (MyRevision)revisionEntity;
        revision.fixTimezone();
        }
    }

@Entity
@RevisionEntity (MyRevisionListener.class)
public class MyRevision
      implements Serializable {

    @Id
    @GeneratedValue
    @RevisionNumber
    private long id;

    @RevisionTimestamp
    @Temporal (TemporalType.TIMESTAMP)
    @Column (nullable = false)
    private Date date;

    private static final ZoneId ZONE_ID_UTC = ZoneId.of("UTC");

    public void fixTimezone() {
        LocalDateTime localDateTime = LocalDateTime.ofInstant(date.toInstant(), ZONE_ID_UTC);
        date = Date.from(localDateTime.atZone(ZoneId.systemDefault()).toInstant());
        }

    @NotNull
    public LocalDateTime getRevisionDate() {
        return LocalDateTime.ofInstant(date.toInstant(), ZoneId.systemDefault());
        }

    ...
    }
