1. tx 配置方法， 代码示例

javabean及其映射文件省略，和上篇的一样

CustomerDao.java， dao层接口

public interface CustomerDao {

	public void insertCustomer(Customer c);

	public void updateCustomer(Customer c);

	public List<Customer> findCustomerByName(String name);

	//批量保存

	//public void saveCustomers(List<Customer> list);

}

CustomerDaoImpl.java ，dao层实现

public class CustomerDaoImpl implements CustomerDao {

	private SessionFactory sf ;

	public void setSf(SessionFactory sf) {

		this.sf = sf;

	}

	public List<Customer> findCustomerByName(String name) {

		String hql = "from Customer c where c.name = ?";

		Query q = sf.getCurrentSession().createQuery(hql);

		q.setString(0, name);

		return q.list();

	}

	public void insertCustomer(Customer c) {

		sf.getCurrentSession().save(c);

	}

	public void updateCustomer(Customer c) {

		sf.getCurrentSession().update(c);

	}

}

CustomerService.java ，service层接口

public interface CustomerService {

	public void insertCustomer(Customer c);

	public void updateCustomer(Customer c);

	public List<Customer> findCustomerByName(String name);

	//批量保存

	public void saveCustomers(List<Customer> list);

}

CustomerServiceImpl.java，service层实现

public class CustomerServiceImpl implements CustomerService {

	//dao

	private CustomerDao dao ;

	//注入dao

	public void setDao(CustomerDao dao) {

		this.dao = dao;

	}

	public List<Customer> findCustomerByName(String name) {

		return dao.findCustomerByName(name);

	}

	public void insertCustomer(Customer c) {

		dao.insertCustomer(c);

	}

	/**

	 * 批量保存, 编程式事务管理

	 */

	public void saveCustomers(final List<Customer> list) {

		for(Customer c : list){

			this.insertCustomer(c);

		}

	}

	public void updateCustomer(Customer c) {

		dao.updateCustomer(c);

	}

}

App.java 测试代码

public class App {

	public static void main(String[] args) throws SQLException {

		ApplicationContext ac = new ClassPathXmlApplicationContext(

				"cn/itcast/spring/hibernate/tx25/sh.xml");

		CustomerService cs = (CustomerService) ac.getBean("customerService");

		List<Customer> list = new ArrayList<Customer>();

		Customer c = null ;

		for(int i = 0 ; i < 10 ; i++){

			c = new Customer();

			if(i == 9){

				c.setName(null);

			}

			else{

				c.setName("tom" + i);

			}

			c.setAge(20 + i);

			list.add(c);

		}

		cs.saveCustomers(list);

	}

}

2. aspectj 配置方法 代码示例

和（1）tx方式相比只有两个文件有变动

CustomerServiceImpl.java， service实现 以加注解的方式

/**

 * 通过注解方法实现事务管理

 */

@Transactional(propagation=Propagation.REQUIRED,isolation=Isolation.DEFAULT)

public class CustomerServiceImpl implements CustomerService {

	//dao

	private CustomerDao dao ;

	//注入dao

	public void setDao(CustomerDao dao) {

		this.dao = dao;

	}

	/**

	 * 只读

	 */

	@Transactional(readOnly=true)

	public List<Customer> findCustomerByName(String name) {

		return dao.findCustomerByName(name);

	}

	public void insertCustomer(Customer c) {

		dao.insertCustomer(c);

	}

	/**

	 * 批量保存, 编程式事务管理

	 */

	public void saveCustomers(final List<Customer> list) {

		for(Customer c : list){

			this.insertCustomer(c);

		}

	}

	public void updateCustomer(Customer c) {

		dao.updateCustomer(c);

	}

}
