如何在Hibernate中存储LocalTime [英] How to store LocalTime in hibernate

问题描述

我有一个实体有一个 LocalTime 类型的变量，我想将它存储在数据库中。所以我有两个问题：

1. mysql中的字段是什么数据类型？


2. 什么注解用于实体？

我不关心日期。

解决方案

hibernate-java8 为持久化 LocalTime 字段提供了一个LocalTimeType。由于hibernate-java8-5.2。+已被合并到hibernate-core模块中。

用法

保存 LocalTime as sql time柱。

  @Column 
私有LocalTime时间; 
  

保存 LocalTime as sql varchar column。

  @Column（columnDefinition =varchar（8））
私有LocalTime时间; 
  

I have an entity that has a variable of type LocalTime and I would like to store it in database. So I have two questions:

1. What data type will the field in mysql be?
2. What annotation to use for entity?

I do not care for date at all whatsoever.

解决方案

hibernate-java8 provide a LocalTimeType for persist a LocalTime field.Since hibernate-java8-5.2.+ has been merged into the hibernate-core module.

Usage

saving LocalTime as sql time column.

@Column
private LocalTime time;

saving LocalTime as sql varchar column.

@Column(columnDefinition = "varchar(8)")
private LocalTime time;
