Hibernate 追随者和痛苦：非法尝试将集合与两个开放会话相关联
我正在开发一个游戏项目，我需要每 10 分钟对玩家进行排名，这很简单！股票游戏。 为了更新玩家排名，我每 10 分钟运行一个线程，该线程获取每个玩家对象（名为玩家），计算其得分，然后移动到下一个玩家，顺便说一下，我将玩家得分存储在它自己的对象中（玩家）。
但我认为这不应该是原因，因为如果更新发生在事务块内，MySql 会保证数据的准确性，那么 hibernate 为什么要限制此功能呢？
我不知道这是否是一个并发问题，是否与我所说的场景有关。 还有一件事是我没有使用 c3p0！与休眠一起，我不知道这是否相关，我只是想提一下。
谢谢转发，
i am working on a game project, where i need to rank players every 10 minutes, it is a simple! stock games.
in order to update player ranks, i run a thread every 10 minutes , the thread fetch every player object(named player), calculates its score and then move on to next player and by the way i am storing the players score in its own object(player).
but i think it shouldn't be the cause, because MySql guarantees the data accuracy if the updates come inside a transaction block, so why should hibernate restrict this feature?
i don't know if this is a concurrency issue and has anything to do with the scenario that i told.
and one thing else is i am not using c3p0! along with hibernate, i donno if this is related or not i just wanted to mention it.
thnx in forward,
