Hibernate JPA Annotations @Temporal (temporaltype.date) Date annotations!

The role of @Temporal tags is simple:

1, if there is a date type of property in a class, the database store may be ' yyyy-mm-dd hh:MM:ss ' to obtain the date and year on the query, the attribute is labeled @temporal (temporaltype.date) will be shaped like ' yyyy-mm-dd ' Format of the date.

DATE: Equals java.sql.Date

Date:

@Temporal (Temporaltype.date)
@Column (name = "Applydate", nullable = false, length = 12)
Public Date getapplydate () {
return applydate;
}

Value at page end: 2016--09--28

2, if there is a date type of property in a class, the database store may be ' yyyy-mm-dd hh:MM:ss ' to obtain seconds and minutes, on which the label @Temporal (Temporaltype.time) will get the shape of the "HH:MM:SS" format of the date.

Time: Equals Java.sql.Time

Time:

@Temporal (Temporaltype.time)

Value at page end: 15:50:30

3, if there is a date type of property in a class, the database store may be ' yyyy-mm-dd hh:MM:ss ' to obtain ' is ' yyyy-mm-dd hh:MM:ss ', the attribute is labeled @Temporal ( Temporaltype.timestamp) will get a date shaped like ' HH:MM:SS ' format

TIMESTAMP: Equals Java.sql.Timestamp

Date and Time (default):

@Temporal (Temporaltype.timestamp)
Value on page: 2016-09-28 15:52:32:000

Control does not display milliseconds in JSP: <TD align= "center" >&nbsp;<fmt:formatdate value= "${list[0].createtime}" pattern= " Yyyy-mm-dd HH:mm:ss "></fmt:formatDate></td>
