来源：互联网发布：易语言30000源码百度云编辑：程序博客网时间：2024/06/15 10:35

自定义的Activiti用户组管理器，主要重写对用户群组的增删改查等操作。

    }

        returnsuper.findPotentialStarterUsers(proceDefId);
    }
 
 
     
}

注意：如果想使用自己定义的用户组表，请重新这个findGroupById(final String groupCode)和findGroupsByUser(final String userCode)，这两个方法是activiti查询的用户组的方法。

2、自定义的Activiti用户组会话工厂，返回类型不要变还是GroupManager，主要是覆盖系统默认添加的用户群组工厂。
