正所谓百家争鸣、见仁见智、众说纷纭、各有千秋！在工作流bpmn2.0可视化建模工具实现的细分领域，网上扑面而来的是 bpmn.js 这个渲染工具包和web建模器，而笔者却认为使用flowable官方开源 editor-app 才是王道。
Flowable 开源版本中的 web 版流程设计器editor-app，展示风格和功能基本跟 activiti-modeler 一样，集成简单，开发工作量小，界面美观大方，功能强大，用户体验友好。
通过以下两张Gif动图来个PK，您的直观感受如何呢？

Flowable editor-app运行效果：
boot-admin 是一款采用前后端分离模式、基于SpringCloud微服务架构的SaaS后台管理框架。系统内置基础管理、权限管理、运行管理、定义管理、代码生成器和办公管理6个功能模块，集成分布式事务Seata、工作流引擎Flowable、业务规则引擎Drools、后台作业调度框架Quartz等，技术栈包括Mybatis-plus、Redis、Nacos、Seata、Flowable、Drools、Quartz、SpringCloud、Springboot Admin Gateway、Liquibase、jwt、Openfeign、I18n等。

下面介绍 boot-admin 对flowable官方bpmn2.0可视化建模工具 editor-app 的集成改造步骤：
获取前端源码
- 下载官方数据包flowable-6.4.1.zip
- 从压缩包中解压出flowable-6.4.1\wars下面的flowable-modeler.war
- 从flowable-modeler.war中解压出 WEB-INF\classes\static\editor-app 文件夹
- 将数据包中 editor-app 文件夹复制到 boot-admin项目 前端工程的 public 文件夹下面
- 在 boot-admin项目 前端工程 public 文件夹下面创建 modeler.html 作为编辑器入口

整合改造前端源码
- 修改 ACTIVITI.CONFIG ，设置网关 URL
var ACTIVITI = ACTIVITI || {};
ACTIVITI.CONFIG = {
'contextRoot' : 'http://网关IP:网关端口号/api/workflow/auth/activiti',
};
- 修改 configuration\url-config.js,设置各具体访问点URL
var KISBPM = KISBPM || {};
KISBPM.URL = {
//通过modelId，获取已保存模型的json数据
getModel: function(modelId) {
return ACTIVITI.CONFIG.contextRoot + '/model/json?modelId=' + modelId;
},
//获取汉化资源json数据
getStencilSet: function() {
return ACTIVITI.CONFIG.contextRoot + '/editor/stencilset?version=' + Date.now();
},
//保存模型数据
putModel: function(modelId) {
return ACTIVITI.CONFIG.contextRoot + '/model/save?modelId=' + modelId;
},
//从cookie中读取令牌
getToken: function() {

- 创建 Modeler.vue 组件，以 iframe 形式将 editor-app 嵌入 vue-element-ui的弹窗 el-dialog 中
