Vue如何实现流程引擎ui绘制 vue结合bpmn实现工作流拖拽功能

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。
前期的准备工作
依赖安装
npm 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
