The Boolean data type for example is mapped on an H2 database to the type boolean.

If the original development team has decided to map boolean values using a string with the value "0" and "1", Hibernate allows to implement user-defined types that are used for the mapping.

@Override
public Object nullSafeGet(ResultSet resultSet, String[] strings,
SessionImplementor sessionImplementor, Object o) throws HibernateException, ←-
SQLException {
String str = (String) StringType.INSTANCE.nullSafeGet(resultSet, strings[0], ←-
sessionImplementor, o);
if ("1".equals(str)) {
return Boolean.TRUE;
}
return Boolean.FALSE;
}
@Override
public void nullSafeSet(PreparedStatement preparedStatement, Object value,
int i, SessionImplementor sessionImplementor) throws HibernateException, ←-
SQLException {
String valueToStore = "0";
if (value != null) {
Boolean booleanValue = (Boolean) value;
if (booleanValue.equals(Boolean.TRUE)) {
valueToStore = "1";
}
}
StringType.INSTANCE.nullSafeSet(preparedStatement,valueToStore, i, ←-
sessionImplementor);
}
