把网线拔掉几分钟后再连上,hibernate就再也不能连接到数据库，这个问题怎么解决？？？

下面是后台输出的错误信息：
Hibernate: select regiondef0_.REGION_ID as REGION1_1_, regiondef0_.NAME as NAME1_, regiondef0_.REGION_TYPE as REGION3_1_, regiondef0_.HOME_ID as HOME4_1_ from MM.REGION_DEF regiondef0_ where regiondef0_.REGION_ID<1000 and regiondef0_.HOME_ID=0

各位高手有没有好办法解决这个问题啊？？？？？？

#2

数据源用的是什么？
如果是JDBC，不要用HIBERNATE自带的连接池，可以用c3p0

#3

下面是获取session的类

package dao;

import org.hibernate.*;
import org.hibernate.cfg.*;

public class HibernateUtil {

    public static final SessionFactory sessionFactory;

    static {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            sessionFactory = new Configuration().configure().buildSessionFactory();
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static final ThreadLocal session = new ThreadLocal();

    public static Session currentSession() throws HibernateException {
        Session s = (Session) session.get();
        // Open a new Session, if this thread has none yet
        if (s == null) {

         //rebuildSessionFactory();
            s = sessionFactory.openSession();
            // Store it in the ThreadLocal variable
            session.set(s);
        }

        return s;
    }

    public static void closeSession() throws HibernateException {
        Session s = (Session) session.get();
        if (s != null)
            s.close();
        session.set(null);
    }


}

用c3p0 上面这样的类要怎么写

谢谢 hbwhwang(catmiw的ID已经停用，现在用这个) 用c3p0 解决网络的问题

<property name="hibernate.c3p0.max_statements">50</property>
这个参数具体是什么作用？
