Annotation Type ColumnDefault

  • @Target({FIELD,METHOD})
    public @interface ColumnDefault
    Specifies that a column has a default value specified in DDL.

    @ColumnDefault may be used in combination with:

    • @DynamicInsert, to let the database fill in the value of a null entity attribute, or
    • @Generated, to populate an entity attribute with the defaulted value of a database column.

    If @Generated is not used, a default value can cause state held in memory to lose synchronization with the database.
