## WordFlow 工作流引擎
|
||
|
||
是一种按照预定义规则【需要符合BPMN规范】进行部署,将业务和节点的流程进行分离【特定形式进行关联】,
|
||
|
||
|
||
### 二、什么是Activiti7?
|
||
|
||
Activiti 是一个工作流引擎, activiti 可以将业务系统中复杂的业务流程抽取出来,使用专门的
|
||
建模语言(BPMN2.0)进行定义,业务系统按照预先定义的流程进行执行
|
||
|
||
https://www.activiti.org
|
||
|
||
2.2 Activiti7内部核心机制
|
||
|
||
1️⃣业务流程图要规范化,需要遵守一套标准。
|
||
|
||
2️⃣业务流程图本质上就是一个XML文件,而XML可以存放所要的数据。
|
||
|
||
3️⃣读取业务流程图的过程就是解析XML文件的过程。
|
||
|
||
4️⃣读取一个业务流程图的结点就相当于解析一个XML的结点,进一步将数据插入到MySQL表中,形成一条记录。
|
||
|
||
5️⃣将一个业务流程图的所有节点都读取并存入到MySQL表中。
|
||
|
||
6️⃣后面只要读取MySQL表中的记录就相当于读取业务流程图的一个节点。
|
||
|
||
7️⃣业务流程的推进,后面就转换为读取表中的数据,并且处理数据,结束的时候这一行数据就可以删除了。
|
||
|
||
### BPMN
|
||
|
||
BPMN(Business Process Model And Notation),业务流程模型和符号,是由BPMI(Business Process Management Initiative)开发的一套的业务流程建模符号,使用BPMN提供的符号可以创建业务流程。2004年5月发布了BPMN1.0规范。
|
||
|
||
> [processOn BPMN 概念](https://www.processon.com/knowledge/bpmndiagram)
|
||
>
|
||
> ### BPMN 的核心元素
|
||
> - 活动:活动是 BPMN 中最基本的元素之一,它代表了业务流程中的一个具体任务或操作。可以自动/手动、
|
||
> - 事件:事件是 BPMN 中用于表示流程中的特定时刻或状态的元素。例如,开始事件、结束事件、中间事件等。
|
||
> - 网关:网关用于控制流程的执行路径,可以实现并行、条件、互斥等多种逻辑。
|
||
> - 泳道:泳道用于将流程分解为多个并行的部分,每个泳道代表一个独立的执行路径。
|
||
|
||
> 一个BPMN的例子:
|
||
> - 当事人填写请假单,启动流程后把请假单ID绑定到流程中;
|
||
> - 部门经理对请假单进行审核;
|
||
> - 然后人事经理进行复核并进行备案;
|
||
> - 最后请假流程结束。
|
||
|
||
### Activiti支持的数据库
|
||
|
||
- Activiti的运行需要数据库的支撑,支持如下:
|
||
- h2
|
||
- MySQL
|
||
- Oracle
|
||
- Db2
|
||
- postgres
|
||
- mysql
|
||
|
||
- 在Navicat工具中创建`activiti`的数据库,用于后续的实验.
|
||
|
||
|
||
|
||
### 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。
|
||

#### 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
|
||
- 并行网关:所有路径都会被选择
|
||
- 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**
|
||
|
||
