我也遇到这个问题，正在寻找解决方法，你的解决了吗？

[heiyedezhou]

同事解决了，是配置文件有问题。

引用 2 楼 heiyedezhou 的回复:

求指导啊。。。能否具体说下是改配置文件的哪里？

[duheng0528]

我把类上增加implements Serializable, TaskListener就可以了。。。。

我觉得出现这个问题是与activiti机制有关，activiti在多条分支充分竞争情况下，同时提交事务更新同一条记录就会产生乐观锁异常，虽然这种情况对于用户任务来说基本上很难发生，因为需要多个分支任务的处理人同时处理任务，这个时间点可能需要维持在几毫秒之间，现实生活中估计很难如此凑巧。
