boot-admin整合flowable官方editor-app进行BPMN2.0建模

2023-04-20 21:07 由 soft1314 发表于 #后端开发

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？

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

  1. 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',
};
  1. 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() {
    var cookies = document.cookie;
    var list = cookies.split("; "); // 解析出名/值对列表

    for (var i = 0; i < list.length; i++) {
      var arr = list[i].split("="); // 解析出名和值
      if (arr[0] == "Admin-Token") {
        var cookieVal = decodeURIComponent(arr[1]); // 对cookie值解码
        break;
      }
    }
    return 'Bearer' + cookieVal;
  }
};
  1. 修改 /public/editor-app/stencil-controller.js 中获取汉化包的方法，由源码中自由访问修改为携带令牌访问后台资源
            $http({method: 'GET',
            headers: {
                  'X-Token': KISBPM.URL.getToken()

后端功能实现

对应前端需求，后端主要实现使用flowable引擎，获取汉化资源、读取模型数据、保存模型数据三个功能。
