事务总结

===============JDBC手动事务========================

/**
	 * 添加流向单
	 * @param flowCard
	 */
	public void addFlowCard(FlowCard flowCard) {
		//Connection conn = null;
		try {
		
			//~~~~~取得Connection~~~~~//
			conn = ConnectionManager.getConnection();
		
			//~~~~~自动提交设置为false~~~~~//
			conn.setAutoCommit(false);
			
			//取得流向单号
			String vouNo = flowCardDao.getVouNo();
			flowCard.setVouNo(vouNo);
			//保存流向单主表
			flowCardDao.addFlowCardMaster(flowCard);
			//保存流向单明细
			flowCardDao.addFlowCardDetail(vouNo, flowCard.getFlowCardDetailList());
			
			//~~~~~~~提交事务~~~~~~~~~~~//
			conn.commit();
			
		}catch(AppException e) {
			if (e.getErrorCode() == ErrorInfo.ERROR_CODE_GEN_FLOW_CARD_VOU_NO
				|| e.getErrorCode() == ErrorInfo.ERROR_CODE_SAVE_FLOWCARD_DETAIL
				|| e.getErrorCode() == ErrorInfo.ERROR_CODE_SAVE_FLOWCARD_MASTER
			) {
				throw new AppException("添加流向单失败！");
			}
		}catch(Exception e) {
			e.printStackTrace();
			try {
			
			 //~~~~~~~事务回滚~~~~~~~~~~~//
				conn.rollback();
			} catch (SQLException e1) {
		 TODO Auto-generated catch block
				e1.printStackTrace();
			}
		}finally {
			ConnectionManager.closeConnection();
		}
	}

===============Hibernate手动事务（需要手动开启，回滚和关闭事务）========================

	
	public class UserManagerImpl implements UserManager {
      Session session=null;
      Transaction tx=null;
	public void addUser(User user) {
		try{
			 //得到当前一个session然后放到threadLocale中,在事务关闭之前可以在项目的任何地方，
			 //使用sessionFactory.getCurrentSession()得到该Session，不需要传递
			session= HibernateUtils.getFactory().getCurrentSession();
			
				//~~~~~得到事务对象~~~~~//
			tx=session.beginTransaction();
			
			session.save(user);
			
			Log log=new Log();
			log.setDate(new Date());
			log.setDetails("XXXX做了什么XXXX");
			log.setType("操作日志");
			LogManager logManager=new LogManagerImpl();
			logManager.addLog(log);
			//throw new java.lang.RuntimeException();//制造异常
			//出现运行期异常，事务自动回滚，数据库没有添加记录
			
			
			//~~~~~~~提交事务~~~~~~~~~~~//
			tx.commit();
		}catch(Exception e){
			e.printStackTrace();
			
		//~~~~~~~事务回滚~~~~~~~~~~~//
			tx.rollback();
		}
		
	}

}

public class LogManagerImpl implements LogManager {
	public void addLog( Log log) {
		HibernateUtils.getFactory().getCurrentSession().save(log);

	}

}

===============Hibernate声明式事务管理========================

 
 a.	用户管理类UserManagerImpl继承模板类HibernateDaoSupport
 
	public class UserManagerImpl extends HibernateDaoSupport implements UserManager {
	
	private LogManager logManager;
	public void addUser(User user) throws Exception {
		this.getHibernateTemplate().save(user);
		
		Log log = new Log();
		log.setType("操作日志");
		log.setDetails("xxx做了xxxxx");
		log.setDate(new Date());
		logManager.addLog(log);
		
		//throw new java.lang.RuntimeException();//制造异常
		throw new Exception();//制造异常,普通异常，事务不回滚
	}
	
	//注入LogManager
	public void setLogManager(LogManager logManager) {
		this.logManager = logManager;
	}

}

b.日志管理类LogManagerImpl继承模板类HibernateDaoSupport
public class LogManagerImpl extends HibernateDaoSupport  implements LogManager {

	public void addLog( Log log) {
		this.getHibernateTemplate().save(log);
	}

}
