public abstract class BaseConverter implements AttributeConverter<Bar, Integer>
{
	private abstract Bar create(Integer value);

	@Override
	public Bar convertToEntityAttribute(Integer t) {
		return create(t);
	}

	@Override
	public Integer convertToDatabaseColumn(Bar t) {
		return t.toInteger();
	}
}

@Converter
public abstract class ConverterImpl extends BaseConverter
{
	@Override
	private Bar create(Integer value)
	{
		return Bar.create(value);
	}
}

The problem is, when you try to convert field with ConverterImpl, it does not work.

Foo.java

@Column
@Convert(converter = ConverterImpl.class)
public Bar bar;
