1.不捕获异常可以正常回滚

    @Transactional(rollbackFor = Exception.class)
    @Override
    public boolean testTransaction() {
        baseMapper.updateById(new Person().setId(1).setTicket(10));
        Integer i = null;
        i = i.intValue() + 1;
        return false;
    }

缺点：如果上层（control）没有捕获异常，进程就会停止

2.捕获异常，并回滚

    @Transactional(rollbackFor = Exception.class)
    @Override
    public boolean testTransaction() {
        baseMapper.updateById(new Person().setId(1).setTicket(10));
        try {
            Integer i = null;
            i = i.intValue() + 1;
        } catch (Exception e) {
            log.info("error: {}", e.getMessage());
            TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
        }
        return false;
    }

核心就是下面这句代码（手动回滚事务）

TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
