/**

 * 为什么切面要切在biz上面不能切在dao层上
 * 明确作用：
 *             切面的目的是为了在目标的对象的方法定义事务特性（add/del/edit/list）
 *                 给上面所列举的方法开启或提交事务等等
 * 
 * 
 * 举例说明切在biz与在dao层上的区别！
 * web层
 *         MoneyAction.transfer(){
 *         MoneyBiz.transfer(User u1,User u2)
 *             }
 * biz层：
 *         MoneyBiz.transfer(User u1,User u2){
 *         MoneyDao.edit(u1);
 *         MoneyDao.edit(u2);
 * 
 * }
 * dao层：
 *         MoneyDao.edit(User u)
 * 
 * 
 * 
 * 银行转账的列子
 * 如果切dao层上：
 *                 SSH解读程序员所写代码
 * biz层：
 *         MoneyBiz.transfer(User u1,User u2){
 *         Transation t1=session.beginTransation();
 *         MoneyDao.edit(u1);
 *         t1.commit();
 *         Transation t2=session.beginTransation();
 *         MoneyDao.edit(u2);
 *         t2.commit();
 * }
 * 
 * 从上面的代码可以看出来，一个转账的功能处于两个事务当中
 *         如果
 *             MoneyDao.edit(u1);
 *                 这里发生了异常
 *             MoneyDao.edit(u2);
 * 
 * 如果切在biz层：
 *                 web层
 *         MoneyAction.transfer(){
 *         Transation t=session.beginTransation();
 *         MoneyBiz.transfer(User u1,User u2)
 *         MoneyDao.edit(u1);
 *             出现了异常
 *         MoneyDao.edit(u2);
 *         t.commit();
