Spring 注解 事务

1、Spring项目中事务手动回滚：

TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();

或者抛出异常：

@Transactional(rollbackFor = { Exception.class, RuntimeException.class })public HousingFundDto slogin(){try {...throw new BusinessException("无法查询基本信息");...}catch (BusinessException e) {throw new BusinessException(e.getErrorDesc());} 

}

2、

 /**     * 更新     */    @Transactional(rollbackFor = { Exception.class, RuntimeException.class })    public void update(Entity entity) {        targetDao.update(entity);    }    /**     * 新增     */    @Transactional(rollbackFor = { Exception.class, RuntimeException.class })    public void insert(Entity entity) {        targetDao.insert(entity);    }
