entity Boolean field default value

[Alexander Curvers]

whats the best way to specify a defailt value for a Boolean entity field,
i would like it to be false but now i get null when i use the getter
even though i set it false in the constructor of the entity it gets set to null when the entity is loaded from database (in the database the value is null by default)
i would like to use annotations so that the table and column are generated in the DB with a default value for the column..

First, JPA does not provide an explicit way to set default values. Use Hibernate annotations for specific defaults.
Still you can do the same thing using @Column and @PrePersist.

	@Column(nullable=false, columnDefinition="boolean default false")
	public Boolean getBoleanValue() {
		return test;
	}

- nullable to set column to not allow null values
- columnDefinition - to give a default value (pay attention, this is an sql specific vendor syntax)

If you want to be independent of db, try @PrePersist to set default value like here:

	@PrePersist
	public void prePersist()
	{
		if ( getBoleanValue() == null )
		{
			setBooleanValue( false );
		}
	}

Hope it helped![/img]
