从3迁移到Hibernate 5 [英] Migrating To Hibernate 5 from 3

问题描述

我正在从3迁移到Hibernate 5.0.3.Final.在3.x中，我正在使用joda-time将LocalDateTime保留在oracle DB中.现在，我看到休眠5不支持joda-time.请让我知道什么是最好的选择?

I am migrating to Hibernate 5.0.3.Final from 3. In 3.x I am using joda-time to persist LocalDateTime in oracle DB. Now I am seeing that hibernate 5 doesn't have a support to joda-time. Please let me know what would be the best alternative for it?

这是代码示例.

import org.joda.time.DateTime;
import org.joda.time.DateTimeZone;
import org.joda.time.LocalDateTime;

public class ComponentHistory {

  @Column(name = EntityConstants.CREATED_BY_COLUMN_NAME)
  private String createdBy;

  @Column(name = EntityConstants.CREATED_DATE_COLUMN_NAME)
  @Type(type = "org.joda.time.contrib.hibernate.PersistentLocalDateTime")
  private LocalDateTime createdDate;

  @Column(name = EntityConstants.UPDATED_BY_COLUMN_NAME)
  private String updatedBy;

  @Column(name = EntityConstants.UPDATED_DATE_COLUMN_NAME)
  @Type(type = "org.joda.time.contrib.hibernate.PersistentLocalDateTime")
  private LocalDateTime updatedDate;

推荐答案

我从Hibernate 4迁移到了5，所以也许适合您，我所做的是删除了所有Joda Time依赖项并将类替换为新的Java Date Api ，就像这样.

I migrated from Hibernate 4 to 5 so maybe can be suitable for you, what I did was remove all Joda Time dependencies and replace the classes to new Java Date Api, like this.

从乔达时间开始

@Type(type="org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
private LocalDateTime startDate;

@Type(type="org.jadira.usertype.dateandtime.joda.PersistentDateTime")
private DateTime creationDate;

到Java 8日期

@Type(type="org.hibernate.type.LocalDateTimeType")
private java.time.LocalDateTime startDate;

@Type(type="org.hibernate.type.ZonedDateTimeType")
private java.time.ZonedDateTime creationDate;

如果有，请删除maven依赖项

Remove maven dependencies if you have it

    <dependency>
        <groupId>joda-time</groupId>
        <artifactId>joda-time-hibernate</artifactId>
        <version>1.3</version>
    </dependency>

    <dependency>
        <groupId>joda-time</groupId>
        <artifactId>joda-time</artifactId>
        <version>2.3</version>
    </dependency>

    <dependency>
        <groupId>org.jadira.usertype</groupId>
        <artifactId>usertype.core</artifactId>
        <version>3.1.0.CR8</version>
    </dependency>

并添加hibernate-java8

And add hibernate-java8

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-java8</artifactId>
        <version>5.0.4.Final</version>
    </dependency>
