### Activiti使用步骤
|
||||||
|
|
||||||
|
> 2.4.1 整合Activiti
|
||||||
|
> Activiti是一个工作流引擎，业务系统使用Activiti来对系统的业务流程进行自动化管理，为了方便业务系统访问（操作）Activiti的接口或功能，通常将Activiti和业务系统的环境集成在一起。
|
||||||
|
> 2.4.2 业务流程建模
|
||||||
|
> 使用Activiti流程建模工具(Activity-designer)定义业务流程(.bpmn文件)。
|
||||||
|
> .bpmn文件就是业务流程定义文件，通过xml定义业务流程。
|
||||||
|
> 如果使用其他公司开发的工作引擎一般都提供了可视化的建模工具（Process Designer）用于生成流程定义文件，建模工具操作直观，一般都支持图形化拖拽方式、多窗口的用户界面、丰富的过程图形元素、过程元素拷贝、粘贴、删除等功能。
|
||||||
|
> 2.4.3 部署业务流程
|
||||||
|
> 向Activiti部署业务流程定义(.bpmn文件)。
|
||||||
|
> 使用Activiti提供的API向Activiti中部署.bpmn文件（一般情况下还需要一起部署业务流程的图片.png）。
|
||||||
|
> 2.4.4 启动流程实例
|
||||||
|
> 启动一个流程实例表示开始一次业务流程的运行，比如员工请假流程部署完成，如果张三要请假就可以启动一个流程实例，如果李四要请假也需要启动一个流程实例，两个流程的执行互不影响，就好比定义一个Java类，实例化两个Java对象一样，部署的流程就好比Java类，启动一个流程实例就好比new一个Java对象。
|
||||||
|
> 2.4.5 查询待办任务
|
||||||
|
> 因为现在系统的业务流程已经交给Activiti管理，通过Activiti就可以查询当前流程执行到哪里了，当前用户需要办理什么任务了，这些Activiti帮我们管理了，而不像传统方式中需要我们在SQL语句中的WHERE条件中指定当前查询的状态值是多少。
|
||||||
|
> 2.4.6 处理待办任务
|
||||||
|
> 用户查询待办任务后，就可以办理某个任务，如果这任务办理完成还需要其他用户办理，比如采购单创建后由部门经理审核，这个过程也是由Activiti帮我们完成了，不需要我们在代码中硬编码指定下一个任务办理人了
|
||||||
|
> 2.4.7 结束流程
|
||||||
|
> 当任务办理完成没有下一个任务/结点了，这个流程实例就完成了。
|
||||||
|

### Service总览
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
- RepositoryService Activiti的资源管理接口：管理和控制流程发布包和流程定义的操作
|
||||||
|
- RuntimeService Activiti的流程运行管理接口：流程执行相关的信息
|
||||||
|
- TaskService Activiti的任务管理接口：
|
||||||
|
- HistoryService Activiti的历史管理接口
|

|
#### 数据表解读
|
||||||
|
|
||||||
|
Activiti 使用到的表都是 ACT_ 开头的，表名的第二部分表示用途。
|
||||||
|
|
||||||
|
##### ACT_GE_ （GE） 表示 general 全局通用数据及设置，各种情况都使用的数据。
|
||||||
|
|
||||||
|
> #### 全局通用数据（ACT_GE_*）
|
||||||
|
>
|
||||||
|
> | ACT_GE_BYTEARRAY | 二进制数据表，存储通用的流程定义和流程资源。 |
|
||||||
|
> | ---------------- | ---------------------------------------------------- |
|
||||||
|
> | ACT_GE_PROPERTY | 系统相关属性，属性数据表存储整个流程引擎级别的数据。 |
|
||||||
|
|
||||||
|
##### ACT_HI_ （HI） 表示 history 历史数据表，包含着程执行的历史相关数据。
|
||||||
|
|
||||||
|
##### ACT_RE_ （RE） 表示 repository 存储，包含的是静态信息。
|
||||||
|
|
||||||
|
##### ACT_RU_ （RU） 表示 runtime 运行时，运行时的流程变量，用户任务，变量，职责（job）等运行时数据。Activiti 只存储实例执行期间的运行时数据，当流程实例结束时，将删除这些记录 （salvio修

- 排他网关：只有一条路径会被选择

- 包容网关：可以在网关上设置条件，**为每个输出设置计算**

- 事件网关：进入等待状态，**等待事件后转为活动状态**
