Migrate from Jadira 7.0.0.CR1 to Java 17

[rcbandit111]

I use 'org.jadira.usertype:usertype.core:7.0.0.CR1' into my project. I want to migrate to Java 17. I have the following columns definitions:

  @Column(name = "update_date")
  @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
  private DateTime requestDate;

Do you know how I can replace the code for latest Java 17/Hibernate/Spring Boot?

it looks like this project has been abandoned.

I recently finished migrating my project to Hibernate 6. You have a couple of options:

1. Use java.time.OffsetDateTime instead of DateTime
2. Write your own custom type for DateTime

Something like this:

public class DateTimeJavaType extends AbstractClassJavaType<DateTime> {

	public static final DateTimeJavaType INSTANCE = new DateTimeJavaType();

	public DateTimeJavaType() {
		super(DateTime.class, ImmutableMutabilityPlan.INSTANCE);
	}

	@Override
	public <X> X unwrap(DateTime value, Class<X> type, WrapperOptions options) {
		if (value == null) {
			return null;
		}
		if (DateTime.class.isAssignableFrom(type)) {
			return (X) value;
		}
		if (Timestamp.class.isAssignableFrom(type)) {
			return (X) new Timestamp(value.toDate().getTime());
		}
		throw unknownUnwrap(type);
	}

	@Override
	public <X> DateTime wrap(X value, WrapperOptions options) {
		if (value == null) {
			return null;
		}
		if (value instanceof Timestamp) {
			return new DateTime(value);
		}
		if (value instanceof DateTime) {
			return (DateTime) value;
		}
		throw unknownWrap(value.getClass());
	}
	
	@Override
	public JdbcType getRecommendedJdbcType(JdbcTypeIndicators indicators) {
		return indicators.getTypeConfiguration()
				.getJdbcTypeRegistry()
				.getDescriptor(Types.TIMESTAMP);
	}
}

Then you can use it like this:

  @JavaType(DateTimeJavaType.class)
  private DateTime until;

@theigl Thanks for the reply. Using java.time.OffsetDateTime looks good enough. Any issues that I might face?

I have the similar problem, but it's about currency mapping:

@Type(type = "org.jadira.usertype.moneyandcurrency.joda.PersistentMoneyAmount")
private Money fee;

anyone gets any idea to work around this?

I assume the previous commenter has since solved their problem, but for future travelers —

Depending on your config, you likely want one of these or something similar:

public class MoneyConverter implements AttributeConverter<Money, Double> {
    @Override
    @Nullable
    public Double convertToDatabaseColumn(@Nullable final Money money) {
        return money == null ? null : money.getAmount().doubleValue();
    }

    @Override
    @Nullable
    public Money convertToEntityAttribute(@Nullable final Double dbData) {
        return dbData == null ? null : Money.of(CurrencyUnit.USD, dbData);
    }
}

public class MoneyConverter implements AttributeConverter<Money, String> {
    @Override
    @Nullable
    public String convertToDatabaseColumn(@Nullable final Money attribute) {
        return attribute == null ? null : attribute.toString();
    }

    @Override
    @Nullable
    public Money convertToEntityAttribute(@Nullable final String dbData) {
        return dbData == null ? null : Money.parse(dbData);
    }
}

Then on your column property:

@Convert(converter = MoneyConverter.class)
private Money fee;

It's pure JPA, so it should work with Hibernate or any other libraries that use JPA.
