再小的个子，也能给沙漠留下长长的身影；再小的人物，也能让历史吐出重重的叹息。——余秋雨《文化苦旅》

我们可以手动管理事务

首先需要引用两个Bean

1
2
3
4
@Resource
private TransactionDefinition transactionDefinition;
@Resource
private IArticleEnclosureService articleEnclosureService;

然后是使用

1
2
3
4
5
6
7
8
9
10
11
      PlatformTransactionManager transactionManager = Objects.requireNonNull(transactionTemplate.getTransactionManager());
      TransactionStatus transactionStatus = transactionManager.getTransaction(transactionDefinition);
if (逻辑执行正确) {
	//提交事务
	transactionManager.commit(transactionStatus);
      } else {
          // 回滚事务
	transactionManager.rollback(transactionStatus);
          // 记录日志
          log.error(e);
      }

或者是

1
2
3
4
5
6
7
8
9
10
11
      PlatformTransactionManager transactionManager = Objects.requireNonNull(transactionTemplate.getTransactionManager());
      TransactionStatus transactionStatus = transactionManager.getTransaction(transactionDefinition);
try{
	//提交事务
	transactionManager.commit(transactionStatus);
      } catch (Exception e) {
          // 回滚事务
	transactionManager.rollback(transactionStatus);
          // 记录日志
          log.error(e);
      }
