MyBatis-Plus 乐观锁修改，锁表，不知道啥情况：Lock wait timeout exceeded; try restarting transaction

当前使用版本(必填,否则不予处理)

3.4.3版本

该问题是如何引起的？(确定最新版也有问题再提!!!)

重现步骤(如果有就写完整)

        UpdateWrapper updateWrapper = new UpdateWrapper();
        updateWrapper.eq("id", sgs.getId());
        updateWrapper.set("stocks", sgs.getStocks() - number);
        updateWrapper.set("version", sgs.getVersion() + 1);
        goodSkuService.update(updateWrapper);

或者这种

        UpdateWrapper updateWrapper = new UpdateWrapper();
        updateWrapper.eq("id", sgs.getId());
        updateWrapper.set("stocks", sgs.getStocks() - number);
        goodSkuService.update(updateWrapper);

都会报错，不知道啥情况，执行到update时，就会锁表。。

实体类有加

@Version private Integer version;

插件也添加了。。
