Failed to store java.time.ZonedDateTime using hibernate PostgreSQL

Question

I have an entity which extends an auditing entity class named AbstractAuditingEntity in which one of the field is

@CreatedDate
@Column(name = "created_date", nullable = false)
@JsonIgnore
private ZonedDateTime createdDate

Above field has mapping to database field named "created_date" with type "timestamp without time zone".

But at the time of saving this entity PostgresSQL throws error as follows :

Caused by: org.postgresql.util.PSQLException: ERROR: column "created_date" is of type timestamp without time zone but expression is of type bytea
  Hint: You will need to rewrite or cast the expression.

I looked for the same error & found solution here : Postgresql UUID supported by Hibernate?

But the solution is for java.util.UUID, in solution it is suggested to add annotation @Type(type="pg-uuid") on a field with UUID type.

Is there any such a ready-to-use type value like pg-uuid for ZonedDateTime ? Any reference link for the different values constants of hibernate @Type annotation ?

Or am supposed to write a custom deserializer class ? How to write such deserializer class any reference link ?

PostgresSQL Version  : 9.6,
<liquibase-hibernate5.version>3.6</liquibase-hibernate5.version>

Answer 1

For Hibernate 5.2 it should just work out of the box.

For 5.0 you can add a dependency to support it:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-java8</artifactId>
    <version>${hibernate.version}</version>
</dependency>

For 4.3 you can use a JPA 2.1 converter:

@Converter
public class TimestampConverter implements AttributeConverter<ZonedDateTime, Timestamp> {
    @Override
    public Timestamp convertToDatabaseColumn(ZonedDateTime zonedTime) {
        if (zonedTime == null) {
            return null;
        }
        return new Timestamp(zonedTime.toInstant().toEpochMilli());
    }

    @Override
    public ZonedDateTime convertToEntityAttribute(Timestamp localTime) {
        if (localTime == null) {
            return null;
        }
        return ZonedDateTime.ofInstant(Instant.ofEpochMilli(localTime.getTime()), ZoneId.systemDefault());
    }
}

Then annotate your attribute with @Convert:

@Convert(converter = TimestampConverter.class)
private ZonedDateTime createdDate;

I note that your database column is TIMESTAMP. It should really be TIMESTAMP WITH TIME ZONE, especially if your client time zone has daylight savings changes.
