Howdy,

In this answer:
don't we need to put @Temporal annotation, as the value of the map is a Date which must have defined temporal type?

Cheers!

Code: Select all

@ElementCollection
@CollectionTable(name="EMP_PROJECTS")
@Column(name="STARTDATE")
private Map<Project, Date> currentProjects;

don't we need to put @Temporal annotation, as the value of the map is a Date which must have defined temporal type?

@Temporal is needed with java.util.Date, and not needed with java.sql.Date

Well everybody in this world when they see Date they think java.util.Date
So this question is misleading.

There are 2 points:
1. The answer to this question doesn't depend on whether there is @Temporal annotation present or not. Both - with and without @Temporal, are fine.
2. Whenever you retrieve a date from the DB using JDBC, you get java.sql.Date. So whenever I see a date in context of a DB, I think java.sql.Date. But again, what I think is irrelevant because that is not the point in this question. It doesn't matter here. Not specifying @Temporal doesn't necessarily make the option incorrect.

HTH,
Paul.
