JPA configure boolean fields to persist as integers

In JPA is there an annotation to specify that boolean fields should be persisted as an integer. I'm using OpenJPA and it's开发者_StackOverflow currently persisting boolean fields as bits. I'd rather use integer 1 or 0.

You can specify the column definition:

@Column(name="boolColumn",
     columnDefinition="INT(1)")

You can use the following annotation:

@Type(type="numeric_boolean")

If you want to write Y and N instead of 0, 1, you can use

@Type(type="yes_no")

Sticking with the question, a long time later, but very related but for Hibernate 4.3.7 higher, you can use

import org.hibernate.annotations.Type;
@Column(name="enabled1", nullable=false)
@Type(type = "org.hibernate.type.NumericBooleanType")  
public Boolean getEnabled() {
    return this.enabled;
}

This has been tested in a migration from PostgreSQL to Oracle to avoid impact on JPA entities
