前言：
? ? ? ?整理在vue项目中使用bpmn.js的过程和源码。
实现最终效果：
目录：
（2）js文件中：xml可以获取本地，也可以用axios获取在线地址
1、bpmn.js的介绍，官网入口
? ? ? ?业务流程模型注解（Business Process Modeling Notation - BPMN）是 业务流程模型的一种标准图形注解。这个标准 是由对象管理组（Object Management Group - OMG）维护的。
2、bpmn.js中实现最简单的效果：
引入插件1：
cnpm install bpmn-js --save-dev开始开发：
（1）页面上：创建容器
<template>
<div class="containers" ref="containers">
<div id="js-canvas" class="canvas" ref="canvas"></div>
</div>
</template>（2）js文件中：xml可以获取本地，也可以用axios获取在线地址
import xmlStr from './xml' //引入默认显示的xml字符串数据import BpmnModeler from 'bpmn-js/lib/Modeler' // 引入 bpmn-js export default {
data () {
return {
bpmnModeler: null,
containers: null
}
},
mounted() {
this.initDiagram()
},
methods:{
//初始化方法
initDiagram(){
this.containers = this.$refs.containers // 获取到属性ref为“containers”的dom节点
const canvas = this.$refs.canvas // 获取到属性ref为“canvas”的dom节点
this.bpmnModeler = new BpmnModeler({
container: canvas,
})
this.createNewDiagram()
},
// 注意：必须先加载一个bpmn文件，新建就是加载一个空的bpmn文件，否则不能拖拽节点
createNewDiagram(){
/**
* 获取后台，获取默认的xml
* */
// var diagramUrl = 'https://cdn.staticaly.com/gh/bpmn-io/bpmn-js-examples/dfceecba/starter/diagram.bpmn';
// this.$axios.get(diagramUrl).then((res)=>{
// console.log(res.data)
// this.openDiagram(res.data)
// }).catch((err)=>{
// console.log(err)
// })
let mr_xml = xmlStr //默认值-xml
// let mr_xml = '' //默认值-xml
this.openDiagram(mr_xml)
},
openDiagram(xml){
/**
* 导入xml（字符串形式），返回导入结果
* 后续会取消传入回调函数的方式
* 推荐使用async/await或者链式调用
* @param { string } xml 流程图xml字符串
* @param { Promise } callback 回调函数，出错时返回{ warnings，err }
*/
this.bpmnModeler.importXML(xml, function(err) {
if (err) {
// container
// .removeClass('with-diagram')
// .addClass('with-error');
console.error(err);
} else {
// container
// .removeClass('with-error')
// .addClass('with-diagram');
}
});
},
}
}(3) css样式
<style lang="scss" scope>
.containers{
position: absolute;
background-color: #ffffff;
width: 100%;
height: 100%;
display: flex;
.canvas{
width: 100%;
height: 100%;
}
.bjs-powered-by {
display: none;
}
}
</style>3、bpmn.js引入中文版
官方不仅仅提供了，中文版，还有其他版本，想了解的点我
在第二步的基础上，js中在引入：
import customTranslate from './customTranslate/customTranslate' //汉化export default {
data () {
return {
bpmnModeler: null,
containers: null,
//加入-------start-----------
customTranslateModule: {
translate: [ 'value', customTranslate ]
}
//加入-------end-----------
}
},
} methods:{
//初始化方法
initDiagram(){
this.containers = this.$refs.containers // 获取到属性ref为“containers”的dom节点
const canvas = this.$refs.canvas // 获取到属性ref为“canvas”的dom节点
this.bpmnModeler = new BpmnModeler({
container: canvas,
//加入-------start-----------
additionalModules: [
this.customTranslateModule,
],
//加入-------end-----------
})
this.createNewDiagram()
},
}4、bpmn.js引入左侧的功能面板
（1）当前页面引入，我用的是scss
加入：
/*左边工具栏以及编辑节点的样式*/
@import '~bpmn-js/dist/assets/diagram-js.css';
@import '~bpmn-js/dist/assets/bpmn-font/css/bpmn.css';
@import '~bpmn-js/dist/assets/bpmn-font/css/bpmn-codes.css';
@import '~bpmn-js/dist/assets/bpmn-font/css/bpmn-embedded.css';完整：
<style lang="scss" scope>
/*左边工具栏以及编辑节点的样式*/
@import '~bpmn-js/dist/assets/diagram-js.css';
@import '~bpmn-js/dist/assets/bpmn-font/css/bpmn.css';
@import '~bpmn-js/dist/assets/bpmn-font/css/bpmn-codes.css';
@import '~bpmn-js/dist/assets/bpmn-font/css/bpmn-embedded.css';
.containers{
position: absolute;
background-color: #ffffff;
width: 100%;
height: 100%;
display: flex;
.canvas{
width: 100%;
height: 100%;
}
.bjs-powered-by {
display: none;
}
}
</style>（2）main.js中引入：
// 以下为bpmn工作流绘图工具的样式
import 'bpmn-js/dist/assets/diagram-js.css' // 左边工具栏以及编辑节点的样式
import 'bpmn-js/dist/assets/bpmn-font/css/bpmn.css'
import 'bpmn-js/dist/assets/bpmn-font/css/bpmn-codes.css'
import 'bpmn-js/dist/assets/bpmn-font/css/bpmn-embedded.css'5、bpmn.js引入右侧的详情面板
?引入：2个插件，加上上面那个，一共是3个
cnpm install --save bpmn-js-properties-panelcnpm install --save camunda-bpmn-moddle代码开发：
页面上增加元素：
<template>
<div class="containers" ref="containers">
<div id="js-canvas" class="canvas" ref="canvas"></div>
增加
<div id="js-properties-panel"></div>
</div>
</template>样式：
/*右侧详情*/
@import '~bpmn-js-properties-panel/dist/assets/bpmn-js-properties-panel.css';
.containers{
display: flex; //新增，为了让右侧和左侧一起看到
}或者在 main.js 中
import 'bpmn-js-properties-panel/dist/assets/bpmn-js-properties-panel.css'js中：先引入配置
//右侧属性栏功能
import propertiesPanelModule from 'bpmn-js-properties-panel'
import propertiesProviderModule from 'bpmn-js-properties-panel/lib/provider/camunda'
import camundaModdleDescriptor from 'camunda-bpmn-moddle/resources/camunda'methods:{
//初始化方法
initDiagram(){
this.containers = this.$refs.containers // 获取到属性ref为“containers”的dom节点
const canvas = this.$refs.canvas // 获取到属性ref为“canvas”的dom节点
this.bpmnModeler = new BpmnModeler({
container: canvas,
//添加控制板-----------增加1-------------
propertiesPanel: {
parent: '#js-properties-panel'
},
//-----------增加1-------------
//左侧
additionalModules: [
this.customTranslateModule,
// 右边的属性栏-----------增加2-------------
propertiesProviderModule,
propertiesPanelModule
//-----------增加2-------------
],
moddleExtensions: {
camunda: camundaModdleDescriptor
}
})
this.createNewDiagram()
},
}6、完整源码：
index.vue
<template>
<div class="containers" ref="containers">
<div id="js-canvas" class="canvas" ref="canvas"></div>
<div id="js-properties-panel"></div>
</div>

createNewDiagram(){
/**

let mr_xml = xmlStr //默认值-xml

this.openDiagram(mr_xml)

openDiagram(xml){
/**

*/
this.bpmnModeler.importXML(xml, function(err) {
if (err) {
// container
// .removeClass('with-diagram')
// .addClass('with-error');
console.error(err);
} else {
