spring - 在 JPA/hibernate 和 spring 中使用 joda time

Question

我会坚持到数据库创建日期和时间。我有一些日期和时间类(class)的经验，但我不喜欢它们。

最近我开始使用 Joda time。我不得不说图书馆是处理日期和时间的最佳选择。

现在我想保留来自 joda 的 DateTime 对象。

我已经试过了:

@Type(type="org.joda.time.contrib.hibernate.PersistentDateTime")
private DateTime creationDate;

但不幸的是它不起作用。这是堆栈跟踪:

还有我的 pom.xml 片段:

<dependency>
    <groupId>joda-time</groupId>
    <artifactId>joda-time</artifactId>
    <version>2.5</version>
</dependency>

希望有人能帮助我。

您可以为此目的使用 Jadira:

将此添加到您的 pom.xml:

<dependency>
    <groupId>org.jadira.usertype</groupId>
    <artifactId>usertype.extended</artifactId>
    <version>3.2.0.GA</version>
</dependency>

并将其放入您的 hibernate 属性中(配置类中的 hibProperties 方法):

properties.put("jadira.usertype.autoRegisterUserTypes", "true");

完成此操作后，您可以从 Joda 属性中删除 @Type 注释，它应该可以正常工作(对我来说适用于 Joda 和 JSR-310)。
