工作流主要解决的主要问题是：为了实现某个业务目标，利用计算机在多个参与者之间按某种预定规则自动传递文档、信息或者任务。工作流概念起源于生产组织和办公自动化领域，是针对日常工作中具有固定程序活动而提出的一个概念，目的是通过将工作分解成定义良好的任务或角色，按照一定的规则和过程来执行这些任务并对其进行监控，达到提高工作效率、更好的控制过程、增强对客户的服务、有效管理业务流程等目的。尽管工作流已经取得了相当的成就，但对工作流的定义还没有能够统一和明确。
最近在预研工作量相关的东西，计划前端使用vue+bpmn.js，后端使用springboot+activi7实现。这个想法很好，网上案例也挺多，发现配置起来很麻烦，网上的很多案例都是报错的。
bpmn.js是国外的程序员开发的，默认都是英文的，汉化的教程也非常多，后面的代码里，也会把汉化加进去。我这里使用的版本是9.0.3
安装依赖
cnpm install bpmn-js --save
汉化准备
汉化的话，需要在新建的Vue项目中，新建两个Js文件

引入依赖和样式
main.js 文件中引入样式
import 'bpmn-js/dist/assets/diagram-js.css';
import 'bpmn-js/dist/assets/bpmn-font/css/bpmn-embedded.css';
页面文件中，引入js依赖
import BpmnModeler from 'bpmn-js/lib/Modeler';
import camundaExtension from '@/camunda/camunda.json'; //定义各个元素拥有的属性配置
import customTranslate from "@/conf/customTranslate";//汉化

运行效果
注意事项
我这里页面中也使用了element-ui，这个的配置就不讲了
