简介：事物的注解我们可以注解在类上也可以注解在方法上。默认事物的注解@Transactional（propagation=Propagation.REQUIRED，rollbackFor = {RuntimeException.class}，timeout=30）这是默认的事物即你在类或者方法上注解@Transactional后默认会是上面的注解
propagation =Propagation.REQUIRED //默认事物传播行为
rollbackFor={RuntimeException.class}// 设置需要进行回滚的异常类数组，当方法中抛出指定异常数组中的异常时，则进行事务回滚。
一、首先保证你的配置事物的配置文件正确，我们的配置文件如下：
<?xml version="1.0" encoding="UTF-8"?>

解决方法一：不要对方法进行try{}catch(Exception e){}操作
解决方法二：如果对方法进行try{}catch(Exception e){ throw new RuntimeException("运行时出错！")} 一定要抛出运行异常。
三、下面是我功能测试代码:
/** * 功能描述：汇总清单表数据到sp_stat_other表中 * pankx * @date 2016年5月13日 上午10:48:42 * @param * @return void */ @Transactional(propagation=Propagation.REQUIRED,rollbackFor = {RuntimeException.class, Exception.class}) public boolean sumDataToSpstatother(String month) { //获取清单表汇总数据 List<Map<String,Object>> spdata = null; try{ spdata =countRecordByMonth(month); SpStatOther spStatOther =null; // int i=0; if(spdata!=null && spdata.size()>0){ for(Map<String,Object> data:spdata){ spStatOther = new SpStatOther(); /* if(i==2){ 注释是测试事物的 spStatOther.setMonth(month); spStatOther.setPartyId(data.get("PARTY_ID").toString()); //spStatOther.setSvcCode(SVC_CODE); spStatOther.setSpServiceId(Long.valueOf(data.get("SP_SERVICE_ID").toString())); spStatOther.setCallNum(Long.valueOf(data.get("CALL_NUM").toString())); spStatOther.setDealDate(new Date()); spStatOtherMapper.insertSelective(spStatOther); }else{*/ spStatOther.setMonth(month); spStatOther.setPartyId(data.get("PARTY_ID").toString()); spStatOther.setSvcCode(SVC_CODE); spStatOther.setSpServiceId(Long.valueOf(data.get("SP_SERVICE_ID").toString())); spStatOther.setCallNum(Long.valueOf(data.get("CALL_NUM").toString())); spStatOther.setDealDate(new Date()); spStatOtherMapper.insertSelective(spStatOther);/*}
i++;*/ } } logger.info("[汇总] 数据汇总成功"); return true; }catch(Exception e){ e.printStackTrace(); logger.info("[汇总] 数据汇总失败" ); throw new RuntimeException("运行时出错！"); } }四、以下是spring配置事物要注意的
注意的几点:
1 @Transactional 只能被应用到public方法上, 对于其它非public的方法,如果标记了@Transactional也不会报错,但方法没有事务功能. 2用 spring 事务管理器,由spring来负责数据库的打开,提交,回滚.默认遇到运行期例外(throw new RuntimeException("注释");)会回滚，即遇到不受检查（unchecked）的例外时回滚；而遇到需要捕获的例外(throw new Exception("注释");)不会回滚,即遇到受检查的例外（就是非运行时抛出的异常，编译器会检查到的异常叫受检查例外或说受检查异常）时，需我们指定方式来让事务回滚要想所有异常都回滚,要加上 @Transactional( rollbackFor={Exception.class,其它异常}) .如果让unchecked例外不回滚： @Transactional(notRollbackFor=RunTimeException.class) 如下: @Transactional(rollbackFor=Exception.class) //指定回滚,遇到异常Exception时回滚 public void methodName() { throw new Exception("注释"); } @Transactional(noRollbackFor=Exception.class)//指定不回滚,遇到运行期例外(throw new Runt希望对大家有帮助!
