Joda time DateTime incorrectly stores in database

问题

I'm storing JodaTime DateTime field to timestamptz column by using org.jadira.usertype:usertype.jodatime:1.9. App server has +4 time zone. DB server +9 time zone. new DateTime() results in ${currentTime+1hour}+9 where +9 is time zone (correct value is ${currentTime+5hours)+9).

I haven't found any related topics. java.util.Date stores correctly.

Domain object has the following mapping property:

static mapping = {
    dateCreated sqlType:'timestamptz'
}

How can I store DateTime correctly?

回答1:

Just set JPA properties:

<property name="jadira.usertype.autoRegisterUserTypes"
          value="true"/>
<property name="jadira.usertype.databaseZone"
          value="jvm"/>
<property name="jadira.usertype.javaZone"
          value="jvm"/>

I had the same issue. Specifying app and db zones in config solved the issue.

            <prop key="jadira.usertype.autoRegisterUserTypes">true</prop>
            <prop key="jadira.usertype.databaseZone">America/Los_Angeles</prop>
            <prop key="jadira.usertype.javaZone">America/Los_Angeles</prop>

Ok. I have spend 8 hours to solve the problem. If your are using usertype project to persist JodaTime, you have to set databaseZone property of PersistentDateTime class equals to current application server timezone (not database!).

But it's better to use official hibernate support. It solves the problem out of the box because it uses java.utl.Date to persist DateTime and java.util.Date correctly persisted by default

回答4:

Try starting JVM with -Duser.timezone=UTC to JAVA_OPTS that way the time is in one zone and you can then do your operations on that to convert it to where ever you are.

Fedor,

Am I right to assume you are using Oracle TIMESTAMP WITH TIME ZONE column? Usertype doesn't support this type yet (i.e. with TIME ZONE) due to the handling with JDBC differing between databases, although the project will be happy to accept patches.

There's some good discussion wrt Oracle here: http://puretech.paawak.com/2010/11/02/how-to-handle-oracle-timestamp-with-timezone-from-java/

I had resolved this problems by creating other PersistentDateTime extends AbstractVersionableUserType.

import java.sql.Timestamp;

import org.hibernate.SessionFactory;
import org.hibernate.usertype.ParameterizedType;
import org.jadira.usertype.dateandtime.joda.columnmapper.TimestampColumnDateTimeMapper;
import org.jadira.usertype.spi.shared.AbstractVersionableUserType;
import org.jadira.usertype.spi.shared.IntegratorConfiguredType;
import org.joda.time.DateTime;

public class PersistentDateTime extends AbstractVersionableUserType<DateTime, Timestamp, TimestampColumnDateTimeMapper> implements ParameterizedType, IntegratorConfiguredType {

@Override
public int compare(Object o1, Object o2) {
    return ((DateTime) o1).compareTo((DateTime) o2);
}

@Override
public void applyConfiguration(SessionFactory sessionFactory) {

    super.applyConfiguration(sessionFactory);

    TimestampColumnDateTimeMapper columnMapper = (TimestampColumnDateTimeMapper) getColumnMapper();
    columnMapper.setDatabaseZone(null);
    columnMapper.setJavaZone(null);
}
}
