Activiti 7+Maven+Idea
1. Activiti 7 介绍
Activiti是一个轻量级的工作流和业务流程管理（BPM）平台，面向业务人员，开发人员和系统管理员。它的核心是用于Java的超快速，坚固的BPMN 2流程引擎。它是开源的，并根据Apache许可进行分发。Activiti可以在任何Java应用程序，服务器，集群或云中运行。它与Spring完美集成，非常轻巧，基于简单的概念。
2. Activiti7 核心
2.1 ProcessEngine
提供对所有公开BPM和工作流操作的服务的访问。
2.2 RuntimeService
RuntimeService:允许创建部署，启动和搜索processinstance。
2.3 TaskService
TaskService:公开用于管理人工(独立)任务的操作，例如声明、完成和分配任务
标识服务:用于管理用户、组及其之间的关系。
2.4 ManagementService
ManagementService:公开引擎管理和维护操作
2.5 HistoryService
HistoryService:服务公开关于正在进行的和过去的流程实例的信息。

制作bpmn流程文件
需要安装Activiti插件
IDEA 插件安装 File->Settings->Plugins 安装新插件actiBPM插件
可能出现查找不到该插件的情况，则可以actiBPM下载通过插件jar文件本地安装
创建bpmn文件，main->resources鼠标右键new->Bpmn File 创建名为test的流程文件
创建文件并打开界面如下
下面是我已经创建好的bpmn流程文件
该流程是一个简单的请假流程
流程开始 StartEvent --> staff(员工填报请假信息)—> Supervisor（主管审批）–(如果大于等于三天)->manager(经理审批)—>personnel（人事入档）----EndeEvent; 由于我的idea的问题，流程线上的条件没有显示出来；
以下是bpmn换成xml格式后的内容

流程的Key值，后面可以通过key值找到指定流程
节点名称staff,Assignee 使用${name} 可在实例化流程时指定员工
剩下的节点同理，
name：Supervisor Assignee: ${supervisorName}
name: personnel Assignee: ${personnelName}
name: manager Assignee: ${managerName}
指定执行条件
