3：测试用例
public class BasicDaoImplTest
{
private AbstractApplicationContext aac //Spring容器
private BasicDao basicDao; //基本数据操作接口
private User user; //用户
@Before
public void init()
{
aac=new ClassPathXmlApplicationContext("applicationContext.xml");
basicDao=(BasicDao)aac.getBean("basicDaoImpl");
}
@Test
public void save()
{
user=new User();
user.setAccount("dog4");
user.setPassword("dogjiayou");
user.setName("狗狗");
user.setAge(3);
user.setSex("男");
user.setGrade("用户");
user.setPhone("493204302941");
user.setBirthday(new Date());
user.setRegistDate(new Date());
boolean result=basicDao.save(user);
assertTrue(result);
}
}
4：Junit错误信息
org.hibernate.HibernateException: save is not valid without active transaction
说的意思好像是没有活动的事物，就无法使用session.getCurrentSession()方法，意思是
说我的注解实现事物管理没有成功，所双请教各位高手这个问题该如何解决？
session.getCurrentSession()？
你用这个？

但Session还是得自己创建啊。

那怎么把Hibernate的事物管理交给Spring容器？
难道要使用以前的编程式事物管理？

容器启动的时候开个session ， 这样就避免了currentsession（）没有的尴尬
