I need to map strategy pattern with following source code. Please help me. :


public interface StrategyInterface {

public void writeToDB();

}

import java.io.File;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Statement;

import net.sf.hibernate.HibernateException;
import net.sf.hibernate.Session;
import net.sf.hibernate.SessionFactory;
import net.sf.hibernate.cfg.Configuration;


public class StrategyA implements StrategyInterface {

int number;
int id;


public void writeToDB() {

number = 30;

try {

SessionFactory sessions =
new Configuration().configure().buildSessionFactory();

Session session = sessions.openSession();
StrategyA sa = new StrategyA();
sa.number = number;
session.save(sa);
session.flush();
session.close();

} catch (HibernateException e) {

e.printStackTrace();
}

}


}

public class StrategyB implements StrategyInterface{

int id;
String word;


public void writeToDB() {

.......

}

}




public class StrategyClient {
public StrategyInterface si;

public StrategyClient() {


}
/**
* @return
*/
public StrategyInterface getSi() {
return si;
}

/**
* @param si
*/
public void setSi(StrategyInterface si) {
this.si = si;
}
public void performOperation(String s)
{
si.writeToDB();
}

public static void main(String[] args) {
StrategyClient sc = new StrategyClient();
sc.setSi(new StrategyA());
sc.performOperation();

}

}

It's unclear exactly what you are trying to map ... Can you give a description of exactly what you want to be in the database?

I suspect you may find either the PersistentEnum type or the class type useful but I can't be sure because I don't know what you're trying to do.
