Hibernate force timestamp to persist/load as UTC [duplicate]

Answer 1

For MySQL only, an alternative to implementing custom Hibernate types is to add the following JDBC options to your JDBC connection URL:

useTimezone=true
serverTimezone=UTC

This will force your JDBC connection into the UTC timezone and ask MySQL to perform conversions from the JVM timezone. The net effect is that you can keep a local timezone on your JVM (e.g. for printing out log messages and so forth), while DATETIME columns will be persisted as UTC.

For example:

<bean id="hibernateAnalysisSessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="hibernateProperties">
        <props>
            <!-- Connection parameters -->
            <prop key="hibernate.connection.driver_class">com.mysql.jdbc.Driver</prop>
            <prop key="hibernate.connection.url">jdbc:mysql://hostname/databaseName?useTimezone=true&amp;serverTimezone=UTC</prop>
            ...

Answer 2

get class public class UtcTimestampType extends TimestampType from your link
and make this code

@org.hibernate.annotations.Type(type = "yourPackage.UtcTimestampType")   
public java.util.Date date;    

using annotations

or

<property name="date" column="yourColumn" type="yourPackage.UtcTimestampType" />  

using *.hbm.xml
