Mapping Set using @ElementCollection

Question

I have the following enum:

package ir.raysis.tcs.rule.days;

public enum Days {
    SUNDAY, MONDAY, TUESDAY, WEDNESDAY,
    THURSDAY, FRIDAY, SATURDAY;
}
         


        

Answer 1

While the other question is correct, the most simple form could be:

@ElementCollection
@Enumerated
private Set enumValues;

everything else would be set by convention over configuration (join-table-name, columns).

I highly recommend using @Enumerated(EnumType.STRING) - look it up why. And you might need @ElementCollection(fetch = FetchType.EAGER) depending on what (and where) you're doing.
