因为这个项目license问题无法开源，更多技术支持与服务请加入我的知识星球。

1、前端编辑带有仿钉钉流程的处理

/** 编辑流程设计弹窗页面 */   const handleLoadXml = (row) => {     console.log("handleLoadXml row",row)     const params = {       flowKey: row.key,       version: row.version     }      queryByKeyAndVersion(params).then(res => {       console.log("queryByKeyAndVersion res",res)       if (res.code === 200 && res.result.hasOwnProperty("id")) {         ddDesignerData.id = res.result.flowKey         ddDesignerData.name = res.result.name         flowJsonData.value = JSON.parse(res.result.flowJson)         flowJsonData.value.category = row.category         flowJsonData.value.appType = row.appType         ddDesignerData.version = res.result.version         designerData.form.processType.push({id: row.category,appType: row.appType})         ddDesignerOpen.value = true       }       else {         designerData.title = "流程设计 - " + row.name;         designerData.deploymentId = row.deploymentId;         designerData.form = {           processType: [],           processName: row.name,           processKey: row.key         }         if (row &&row.deploymentId) {           const selectItem = categorys.value.find(item => item.id == row.category);           modelForm.processType = selectItem; //以便编辑保存的时候获取到processType           designerData.form.processType.push(selectItem);           designerData.loading = true;           console.log("designerData",designerData)           handleReadImage(row.deploymentId);           designerData.title = "编辑流程图";           }         xmlFrame.width = '90%'       }     })     }

2、后端检查是否有相应的仿钉钉flowKey和版本号相同的仿钉钉数据

<mapper namespace="org.jeecg.modules.flowable.FlowDd.mapper.FlowDdMapper">    <select id="selectByKeyAndVersion" resultType="org.jeecg.modules.flowable.FlowDd.entity.FlowDd">         select * from flow_dd         where flow_key= #{flowKey} and version = #{version} limit 1     </select> </mapper>

3、前端编辑后保存

const ddSave = (data: any) => {     console.log("ddSave data",data)     saveXmlJson(data).then(res => {       if(res.code === 200) {         createMessage.success(res.message);         ddDesignerData.loading = false;         ddDesignerOpen.value = false;         getList();       }       })   }

其中前端数据如下：

const save = () => {   const processModel = {     code: pCode.value,     name: pName.value,     icon: {       name: 'el:HomeFilled',       color: '#409EFF'     },     process: props.process,     flowJson: JSON.stringify(props.process),     category: props.processType[0].id,     appType: props.processType[0].appType,     enable: true,     version: props.version,     sort: 0,     groupId: '',     remark: ''   }   emit('save', processModel); }

4、后端保存跟原来差不多

@Override 	@Transactional(rollbackFor = Exception.class) 	public Result saveDdModel(ProcessModel processModel) { 		try { 			FlowSaveXmlVo vo = new FlowSaveXmlVo(); 	        BpmnModel bpmnModel = processModel.toBpmnModel(); 	        FlowDd flowDd = new FlowDd(); 	        flowDd.setId(processModel.getId()); 	        flowDd.setName(processModel.getName()); 	        flowDd.setFlowKey(processModel.getCode()); 	        flowDd.setVersion(processModel.getVersion()+1); 	        //String flowJson = JSON.toJSONString(processModel);//有问题，会转换成大写的问题 	        String flowJson = processModel.getFlowJson(); 	        flowDd.setFlowJson(flowJson); 	        flowDdService.save(flowDd); 	        String xml = new String(new BpmnXMLConverter().convertToXML(bpmnModel)); 	        vo.setAppType(processModel.getAppType()); 	        vo.setCategory(processModel.getCategory()); 	        vo.setXml(xml); 	        vo.setDesignerType("DingDing"); 	        return this.saveXmlMode(vo);     	} catch (Exception e) {             e.printStackTrace();             throw new RuntimeException("创建失败: e=" + e.getMessage());         } 	}

5、效果图
