 # 工作流功能说明
----
+
 ### 1.流程设计
 可以新建一个流程或者直接导入BPMN定义文件
 融租易的环境有一些样例，可以下载学习。

后端开发/activiti_demo.md

+# 工作流demo
+
+整体流程
+* 打开工作流模块，设计工作流流程
+* 实现一个当前功能启动工作流的接口
+* 在自己的业务层调用自己实现的工作流类
+* 启动工作流
+
+1 新建工作流并填写对应的信息
+![](/assets/wfl_demo_1.png)
+![](/assets/wfl_demo_2.png)
+
+2 编辑对应的审批节点链，可参考已实现的工作流程
+![](/assets/wfl_demo_3.png)
+
+3 编写一个自己的实现类，实现IActivitiCommonService接口
+![](/assets/wfl_demo_4.png)

+4 启动工作流
+ ```
+Map<String,Object> params = new HashMap<String,Object>();params.put("workFlowType","PRJ_PROJECT");activitiStartService.start(iRequest,projects,params);
