hbm2java generate wrong type for hibernate type "timestamp"
-----------------------------------------------------------
Key: HBX-725
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-725
Project: Hibernate Tools
Type: Bug
Components: hbm2java
Versions: 3.2beta6
Environment: Window XP, java 1.4.2
Reporter: wanhing
When I use "timestamp" in the mapping definition file, the generated java class
has "Date" instead. As a result I lost the granuity that I need. Example:
====================================================================
<class name="TaskDuration">
<meta attribute="class-description">
@jboss-net.xml-schema urn="tms:TaskDuration"
</meta>
<id name="id" column="TaskDurationId" type="long"
>
<generator class="native"/>
</id>
<version name="version" />
<property name="datetime" type="timestamp"
not-null="true"/>
<property name="duration" type="float"
not-null="true"/>
</class>
=====================================================================
The generated java class has:
public class TaskDuration implements java.io.Serializable {
....
private Date datetime;
public void setDatetime(Date datetime) {
this.datetime = datetime;
}
public Date getDatetime() {
return this.datetime;
}
...
}

-----------------------------------------
what granularity do you want ? the Date has downto milliseconds. This is the expected
behavior.

-----------------------------
But this is not the documented behaviour. According to Hibernate documentation, hibernate
timestamp is mapped to java.sql.Timestamp, which has nano value. Millisec might be enough
for most but not enough for some (including us), that's why Java has
java.sql.Timestamp. Also if both hibernate date and timestamp map to java Date, then why
bother to have hibernate "timestamp" type?

Max Rydahl Andersen closed HBX-725:
-----------------------------------
Resolution: Fixed
use <meta attribute="property-type">java.sql.Timestamp</meta> if you
want to be dependent on on java.sql.*
and java.util.Date date = new Timestamp(); does compile.
Furthermore read up about what the difference is between "date",
"time" and "timestamp" in hibernate mappings.
And finally, use the tools forum for question like this :)
