Activiti分为个人任务和组任务，又各有3种分配方式。
- 指定
- 变量
- 监听器
*后台服务基于Springboot2 + Activiti6，整合文章请参考：https://blog.csdn.net/yy756127197/article/details/101211510 不需要流程设计器就排除3,4步骤 *
1. 个人任务

2.3 运行
2.3.1 部署
运行deploy()
2.3.2 启动流程
运行start()
效果：
数据表ACT_RU_IDENTITYLINK中添加了6条数据，admin分为candidate和participant，代表任务候选人和流程实例参与者。
2.3.3 查询任务
运行queryTaskByProcessInstanceId()， 查询第一个用户节点（指定候选人）
效果：
2.3.4 认领任务
运行claimTask()，用户admin认领当前任务
效果
2.3.5 完成任务
运行completeTask2()，设置流程变量，指定下一节点候选人
效果
2.3.6 查询任务
运行queryTask()， 查询第二个用户节点（变量）
效果：
2.3.7 完成任务
运行completeTask()
2.3.8 查询任务
运行queryTask()， 查询第三个用户节点（监听器）
效果：
3. 组任务
组任务跟个人任务设置方式一样，区别在于流程设计器中使用
还有就是，组的数据从ACT_ID_GROUP获取，设置成表中name字段的值。 因为Activiti的权限表功能单一，所以一般不建议使用，适用业务自己的权限表。
如果想用，那就同步业务权限数据到Activiti，用户表对应ACT_ID_USER，角色表对应ACT_ID_GROUP，用户角色关系表对应ACT_ID_MEMBERSHIP
