Springboot @Transactional大事务处理的几点建议

@Autowired
private TransactionTemplate transactionTemplate;

public void testTransaction() {
    transactionTemplate.execute(new TransactionCallbackWithoutResult() {
        @Override
        protected void doInTransactionWithoutResult(TransactionStatus transactionStatus) {
            try {
                // ....  业务代码
            } catch (Exception e){
                //回滚
                transactionStatus.setRollbackOnly();
            }
        }
    });
}

@Service
public class TransactionTestService{

// 避免同一个类内部方法相互调用，实例方法调用代理方法而导致事务失效
    @Resource
    private TransactionTestService service;

    public void create(ParamDto dto){
        queryData1();
        queryData2();
        service.save(dto);
    }
  
	//事务操作
    @Transactional(rollbackFor = Exception.class)
    public void save(ParamDto dto){
        paramDao.insert(dto);
    }
}

反例：
	//事务操作
    @Transactional(rollbackFor = Exception.class)
    public void save(ParamDto dto){
    // 调用了其他服务
        otherRemoteApi();
        paramDao.insert(dto);
    }
    
修改为：
	@Autowired
    private TransactionTemplate transactionTemplate;
    
    public void save(ParamDto dto){
    // 调用了其他服务
        otherRemoteApi();
        transactionTemplate.execute(new TransactionCallbackWithoutResult() {
        @Override
        protected void doInTransactionWithoutResult(TransactionStatus transactionStatus) {
            try {
                  paramDao.insert(dto);
            } catch (Exception e){
                //回滚
                transactionStatus.setRollbackOnly();
            }
        }
    });
      
    }
