此时在DAO上需加上@Transactional注解，如下：

1.package com.bluesky.spring.dao;
2.import java.util.List;
3.import org.hibernate.SessionFactory;
4.import org.springframework.beans.factory.annotation.Autowired;
5.import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
6.import org.springframework.stereotype.Component;
7.import com.bluesky.spring.domain.User;
8.@Transactional
9.@Component("userDao")
10.public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
11. public List<User> listUsers() {
12. return this.getSession().createQuery("from User").list();
13. }
14.}
