c3p0怎么可以连接多个数据库?

Question

我的项目用c3p0连接数据库直接用Session session = HibernateSessionFactory.currentSession();
public class HibernateSessionFactory{
private static String CONFIG_FILE_LOCATION = "/hibernate.cfg.xml";
private static final ThreadLocal threadLocal = new ThreadLocal();
private static Configuration configuration = new Configuration();
private static org.hibernate.SessionFactory sessionFactory;
private static String configFile = CONFIG_FILE_LOCATION;

static {
    try {
        configuration.configure(configFile);
        sessionFactory = configuration.buildSessionFactory();
    } catch (Exception e) {
        System.err
                .println("%%%% Error Creating SessionFactory %%%%");
        e.printStackTrace();
    }
}
private HibernateSessionFactory() {
}
