POJO name

I want generate POJO class like

POJOBase.java instead of POJO.java.

I tried with hbmtemplate filepattern, but is only changing the file name not the class name inside the file.

Any pointers?

Thanks

You can either use the hibernate.reveng.xml file and specify the class name for each table individually. But it sounds like you want to create a class that extends the DelegatingReverseEngineeringStrategy and override the tableToClassName method. e.g.

Code:

package eg.reveng;

import org.hibernate.cfg.reveng.DelegatingReverseEngineeringStrategy;
import org.hibernate.cfg.reveng.ReverseEngineeringStrategy;
import org.hibernate.cfg.reveng.TableIdentifier;

public class Test extends DelegatingReverseEngineeringStrategy {

   public Test(ReverseEngineeringStrategy delegate) {
      super(delegate);
   }

   @Override
   public String tableToClassName(TableIdentifier tableIdentifier) {
      return super.tableToClassName(tableIdentifier) + "Base";
   }

}

no, that would make the mappings go to BasePojo too. Not what he want's (I think)

What he could do is implement getMetaAttributes in revengstrategy; then he would get a BasePojo generated with proper mappings.

Hi Dear all,

I would like to have somthing like preddy98, where I need to generate the Base class. I tried with Ananasi solution where I overide the tableToClassName like this :

public String tableToClassName(TableIdentifier identifier){
return super.tableToClassName(identifier)+"EOBase";
}

This cause all the POJO class name changed to POJOEOBase and the file name of the HBMXML files also changed to tableEOBase.hbm.xml.

My questions. How can I change only the POJO filename and HBMXML reminds the same for e.g : tablehbm.xml?

joy4all, Use a seperate ant task for hbm.xml files.

<target name="hibernate_1" description="Reverse Engineer classes from DB" depends="compile">
<hibernatetool destdir="${gen-src.dir}">
<jdbcconfiguration packagename="xxx.base"
configurationfile="hibernate.cfg.xml"
revengfile="hibernate.reveng.xml"
reversestrategy="xxx.RevStrategy"
detectmanytomany="false"/>
<hbm2java jdk5="true"/>
</hibernatetool>
</target>

<target name="hibernate" description="Reverse Engineer classes from DB" depends="hibernate_4">
<hibernatetool destdir="${gen-src.dir}">
<jdbcconfiguration packagename="xxx.om"
configurationfile="hibernate.cfg.xml"
revengfile="hibernate.reveng.xml"
detectmanytomany="false"/>
<hbm2hbmxml/>
<hbm2cfgxml/>
</hibernatetool>
</target>

Max, I did want db mappings to go into the base class. The idea is that generated base classes will not be modified. So we can sefely replace them everytime they are generated.

The subclasses on the otherhand may be modified to have additional behaviour.

For Example : User extends UserBase

DAOs and services use subclass User for transactional code.

Thanx

Thanks for ur solution preddy98. Between, do u know how to generate the subclass that willl extends the base class ?

I tried to generate in 2 Ant task that call hb2java. The first anttask will use generic Pojo template. (this is use to generate the base class)

The second one will use the custom template that overides the Pojo.ftl. (this is for subclass)

I can generate the files..but the problem is when the table have composite-id. It will generate 2 class in my subclass.

For example :

I have 1 table call "CustOrder" that will contained the customer-id and order-id.

When I use the hibernate tools.
The fist ant task will generate. In my base package, it generate :
CustOrderBase.java
CustOrderBaseId.java

And in my 2nd Antask. In my subpackage, I want only 1 class to be generated..which is
CustOrderSub.java (that will extends the CustOrder Base class)..
