测试代码：HibernateTest.java

代码：

/**

package com.b510.examplex;

import org.hibernate.Session;
import org.hibernate.Transaction;

/**
 *
 * @author XHW
 *

public class HibernateTest {

 /**
  * @param args

  test.testTransaction();
 }

 public void testTransaction() {
  Session session = HibernateSessionFactoryUtil.getSessionFactory()
    .openSession();
  Transaction tx = session.beginTransaction();

  Guestbook guestbook = new Guestbook();
  guestbook.setName("Hongten");
  guestbook.setPhone("123456");
  guestbook.setEmail("hongtenzone@foxmail.com");
  guestbook.setTitle("hello world!");
  guestbook.setContent("hello world!hello world!");
  guestbook.setCreatedTime(new java.util.Date());

  try {
   session.save(guestbook);
  } catch (Exception e) {
   e.printStackTrace();
   if (tx.isActive()) {
    tx.rollback();
   }
  }
  tx.commit();
 }

}

运行效果：
