Project to build activiti process: https://blog.csdn.net/zc_ad/article/details/83271540
-----------------------------------------------
Seven core interfaces, 28 table
(A) seven interfaces
RepositoryService: providing a series of management processes and deploy process definitions API.
RuntimeService: the management and control of process instances in the process is running.
TaskService: to manage process tasks, such as task reminders, create tasks and task completion.
IdentityService: API to provide data management process roles, these roles include the relationship between the data user groups, users, and they are.
ManagementService: Provides process engine management and maintenance services.
HistoryService: the process of historical operating data, including the query, delete the historical data.
FormService: Forms service.
(B) 28 tables
1, act_ge_ generic data table, ge is the general abbreviation
2, act_hi_ history data table, the history Hi is the abbreviation, the corresponding interfaces HistoryService
3, act_id_ identity data table, id is an abbreviation of identity, the interface corresponding to IdentityService
4, act_re_ process storage table, Re is an abbreviation for the repository, the corresponding RepositoryService interfaces, storage and deployment process flow definition data and other static
5, act_ru_ runtime data table, ru for runtime abbreviation, the corresponding dynamic data RuntimeService TaskService interfaces and interfaces, and the process instance stored user tasks

Creating bpmn document workflow, I was drawn based on war paint bpmn's official website provides, there are other methods used IDEA plug-in painting, you can test yourself. activiti. Download activiti official website: https: //www.activiti.org/get-started, download 6.x version.
There is a activiti-app.war project after wars unpacked directory, this project placed under tomcat, tomcat8 own use, and then run. After running the access path is http: // localhost: 8080 / activiti-app, this time need to log in, use the default password on the account, account number: admin, password: test.
1. The design process provide Activiti activiti-app.war applications deployed to Tomcat webapps directory.
2. Create a new MySql database. Activiti-app.properties modify configuration files \ \ \ under activiti-app WEB-INF classes META-INF \ activiti-app directory, use the H2-memory database by default, you will be lost after the restart model creation, into use MySql database.
3. browser to access http: // localhost: 8080 / activiti-app, login accounts: admin: test
Creating bpmn process model
在创建一个bpmn模型时，model_name是文件的名称，model_key是工作流的key，如果部署两个相同key的bpmn模型时，第二个部署的bpmn模型版本号会加1，所以尽量不要创建相同key的bpmn模型。
创建一个bpmn流程模型最少需要有开始节点、任务节点、结束节点。只要将各个节点拖拉到画图界面就行了，在创建执行人的时候，只是将执行人写死(学习的时候才会这样，以后讲述如果动态获取执行人与候选人)。其实一个节点的属性有很多，name与assignments只是最基本的属性。
排它网关与并行网关这两个组件使用的比较多。
1)排他网关：对一个事件流向线的分支决策节点，决定着任务的流向
2)并行网关：通过一个节点，进行决策后，分别同时执行两个流程线，然后再归到另一个节点上统一走向结束节点
创建完后，将文件导出下载下来，放在resources项目下的目录中备用。
感觉这节讲的很简约，主要讲了一些bpmn创建工具，以及简单的使用，后面有使用到动态添加执行人，以及通过会签添加多个候选人在后续会降到，循序渐进嘛，就是这样的。第二章也没有讲如果快速部署、执行任务、查询历史等，第三章主要将的是activiti中的数据库表以及七大接口。
