我愛java系列---【springBoot中手動開啟事務】

springBoot中手動開啟事務，直接看例子：

 @Autowired DataSourceTransactionManager dataSourceTransactionManager; @Autowired TransactionDefinition transactionDefinition; TransactionStatus transactionStatus = null;

    @Override
    public void add(ChannelDetail channelDetail) {

        try {
            log.info("通道管理實現類-新增-入參：channelDetail：{}", channelDetail);
            //手動開啟事務
            transactionStatus = dataSourceTransactionManager.getTransaction(transactionDefinition);
            //新增通道信息
            channelMapper.insertSelective(channelDetail.getChannel());
            //生效時間默認為當天生效
            ChannelPriceBatch channelPriceBatch = channelDetail.getChannelPriceBatch();
            channelPriceBatch.setChannelId(channelDetail.getChannel().getId());
            channelPriceBatchMapper.insert(channelPriceBatch);
            //手動提交事務
            dataSourceTransactionManager.commit(transactionStatus);
        } catch (Exception e) {
            log.error(e.getMessage(), e);
            //手動回滾事務
            dataSourceTransactionManager.rollback(transactionStatus);
            throw new RuntimeException("新增通道失敗");
        }
    }
