基于jeecgboot-vue3的Flowable流程仿钉钉流程设计器-抄送服务处理

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、因为仿钉钉设计器里抄送人是一个服务任务，所以要根据这个服务任务进行处理

2、前端就是一个抄送，选择人

3、这里用了jeecg的选择人组件

<el-form-item prop="users" label="指定人员" v-if="activeData.assigneeType === 'user'">       <div style="width:100%">         <j-select-user-by-dept            :zIndex="3000"           v-model:value="activeData.users"            :multi="true"            :placeholder="`请选择${type}人`"           @getSelectResult="handleSelectUsers">         </j-select-user-by-dept>       </div>          </el-form-item>

4、后端对这个处理如下：

public class CcNode extends AssigneeNode {     // 表单属性     private List<FormProperty> formProperties = new ArrayList<>();     // 操作权限     private Map<String, Boolean> operations = new LinkedHashMap<>();      @Override     public List<FlowElement> convert() {         ArrayList<FlowElement> elements = new ArrayList<>();         // 服务节点         ServiceTask serviceTask = new ServiceTask();         serviceTask.setId(this.getId());         serviceTask.setName(this.getName());         // serviceTask.setAsynchronous(true);         serviceTask.setImplementationType(ImplementationType.IMPLEMENTATION_TYPE_CLASS);         serviceTask.setImplementation("org.jeecg.modules.flowable.ServiceTask.ccDelegate");         //增加扩展属性 add by nbacheng         Map<String, List<ExtensionElement>> extensionElements = new HashMap<String, List<ExtensionElement>>();         ExtensionElement extensionElementTotal = new ExtensionElement();         extensionElementTotal.setName("flowable:properties");          ExtensionElement extensionElement = new ExtensionElement();         extensionElement.setName("flowable:property");         ExtensionAttribute extensionAttributeName = new ExtensionAttribute();         extensionAttributeName.setName("name");         extensionAttributeName.setValue("ccUserList");         extensionElement.addAttribute(extensionAttributeName);         ExtensionAttribute extensionAttributeValue = new ExtensionAttribute();         extensionAttributeValue.setName("value");         extensionAttributeValue.setValue(StringUtils.join(this.getUsers(), ","));         extensionElement.addAttribute(extensionAttributeValue);         extensionElementTotal.addChildElement(extensionElement);         extensionElements.put("ccUserList", CollUtil.newArrayList(extensionElementTotal));         serviceTask.setExtensionElements(extensionElements);         elements.add(serviceTask);         // 下一个节点的连线         Node child = this.getChild();         SequenceFlow sequenceFlow = this.buildSequence(child);         elements.add(sequenceFlow);         // 下一个节点         if (Objects.nonNull(child)) {             child.setBranchId(this.getBranchId());             List<FlowElement> flowElements = child.convert();             elements.addAll(flowElements);         }         return elements;     }  }
