### I 绘制流程图,部署流程图 ###

使用eclipse画流程图---->>>[eclipse安装插件][eclipse]  
简单maven的demo项目---->>>[今日头条][Link 1]

\*.bpmn 给计算机看的 **流程图其实就是xml文件**  
\*.png 给用户看的

画流程图---->>>[画流程图][Link 2]

### II 执行和管理工作流 调用activiti的api ###

启动流程是通过流程定义文件Key创建一个流程实例的过程，类似于我们根据类名new出一个对象的原理，一个流程定义文件可以生成许许多多的流程实例

存放流程数据用了23张表,存放业务数据需要自己建表(业务要关联流程)

## 开发 ##

1.  导包 build path
2.  调用ProcessEngine的api创建23张表(使用java)

ProcessEngineConfiguration processEngineConfiguration =
    	ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration;
    	//连接数据库配置 : 设置驱动,url,设置用户名密码
    
    	//设置databasesSchema

![在这里插入图片描述][70]

ProcessEngine processEngine = ProcessEngineConfiguration.buildProcessEngine();

1.  使用配置文件activiti-context.xml

applicationContext-action.xml文件：

applicationContext-dao.xml文件：

applicationContext-service.xml:

配置applicationContext.xml

### 流程定义的curd ###

Deployment

存储完毕后将在**部署对象表**`act_re_deployment` **流程定义表**`act_re_procdef`中体现
