在Hibernate中创建列类型Datetime

Question

What is the proper way to create column type Datetime in MariaDB using Hibernate? I tried this:

@Column
@Type(type = "date")
@Temporal(TemporalType.DATE)
private Date created_at;

But I can't find a proper type in TemporalType for Datetime.

Answer 1

您需要使用TemporalType.TIMESTAMP作为DateTime。

Answer 2

This is what you need to do.

@Column
@Temporal(TemporalType.TIMESTAMP)
private Date created_at;

Answer 3

You don't need to write @Type(type = "date") . And change your TemporalType to TimeStamp . So finally your code will be like this;

@Column
@Temporal(TemporalType.TIMESTAMP)
private Date created_at;

PS: You don't need to write @Column tag.

Answer 4

Use the columnDefinition attribute of the @Column annotation:

@Column(name = "startTime", columnDefinition="DATETIME")
@Temporal(TemporalType.TIMESTAMP)
private Date startTime;
