How to set a default entity property value with Hibernate
If you want a real database default value, use columnDefinition
:
@Column(name = "myColumn", nullable = false, columnDefinition = "int default 100")
Notice that the string in columnDefinition
is database dependent. Also if you choose this option, you have to use dynamic-insert
, so Hibernate
doesn't include columns with null
values on insert. Otherwise talking about default is irrelevant.
But if you don't want database default value, but simply a default value in your Java code, just initialize your variable like that - private Integer myColumn = 100;
Use hibernate annotation.
@ColumnDefault("-1")
private Long clientId;
Recreate the table if it already exists for the changes to take effect.
