今天我们实现nbcio-boot的flowable的流程跳转功能。

一、前端实现

界面实现，就是点击跳转出来的窗口

<!--跳转流程--><a-modal :z-index="100" :title="jumpTitle" @cancel="jumpOpen = false" :visible.sync="jumpOpen" :width="'40%'" append-to-body><el-form ref="jumpForm" :model="jumpForm" label-width="160px"><el-form-item label="跳转节点" prop="jumpType" :rules="[{ required: true, message: '请选择跳转节点', trigger: 'blur' }]"><a-tablesize="middle":columns="jumpNodeColumns":loading="jumpNodeLoading":pagination="false":dataSource="jumpNodeData":rowKey="(record) => record.id":rowSelection="{ selectedRowKeys: selectedRowKeys, onChange: onSelectChange ,type:'radio' }"/></el-form-item><el-form-item label="处理意见" prop="comment" :rules="[{ required: true, message: '请输入处理意见', trigger: 'blur' }]"><el-input type="textarea" v-model="jumpForm.comment" placeholder="请输入处理意见" /></el-form-item><el-form-item label="附件"  prop="commentFileDto.fileurl"><j-upload v-model="jumpForm.commentFileDto.fileurl"   ></j-upload></el-form-item></el-form><span slot="footer" class="dialog-footer"><el-button @click="jumpOpen = false">取 消</el-button><el-button type="primary" @click="jumpComplete(true)">确 定</el-button></span></a-modal>

相关处理函数如下：

/** 跳转 */handleJump() {this.jumpOpen = true;this.jumpTitle = "跳转流程";this.jumpNodeLoading = trueuserTaskList({ taskId: this.taskForm.taskId }).then((res) => {this.jumpNodeLoading = falsethis.jumpNodeData = res.result})},jumpComplete() {if (this.selectedRows.length < 1) {this.$message.warning('请选择跳转节点')return}// 流程信息this.jumpForm.deployId = this.$route.query && this.$route.query.deployId;this.jumpForm.taskId = this.$route.query && this.$route.query.taskId;this.jumpForm.procInsId = this.$route.query && this.$route.query.procInsId;this.jumpForm.instanceId = this.$route.query && this.$route.query.procInsId;// 初始化表单this.jumpForm.procDefId = this.$route.query && this.$route.query.procDefId;this.jumpForm.businessKey = this.$route.query && this.$route.query.businessKey;this.jumpForm.category = this.$route.query && this.$route.query.category;this.jumpForm.dataId = this.$route.query && this.$route.query.businessKey;//节点类型this.jumpForm.nodeType = this.$route.query && this.$route.query.nodeType;//online表单id和数据idthis.jumpForm.onlineId = this.$route.query && this.$route.query.onlineId;if (this.jumpForm.category === 'online') {this.jumpForm.onlineDataId = this.$route.query && this.$route.query.businessKey;}  //对formdesigner后续加签审批的时候需要用到this.jumpForm.values = this.taskForm.values;//目标选择的节点信息this.jumpForm.targetActId = this.selectedRows[0].id;this.jumpForm.targetActName = this.selectedRows[0].name;console.log("this.jumpForm=",this.jumpForm);jumpTask(this.jumpForm).then(res => {if (res.success) {this.$message.success('跳转成功')this.jumpOpen = false;this.goBack();} else {this.$message.error('跳转失败：' + res.message)}});},/*** 跳转节点列表选择*/onSelectChange (selectedRowKeys, selectedRows) {this.selectedRowKeys = selectedRowKeysthis.selectedRows = selectedRows},

二、后端代码实现

@Override@Transactional(rollbackFor = Exception.class)public void jumpTask(FlowTaskVo flowTaskVo) {//校验任务是否存在Task task = taskService.createTaskQuery().taskId(flowTaskVo.getTaskId()).singleResult();//当前节点idString currentActId = task.getTaskDefinitionKey();//获取流程实例idString processInstanceId = task.getProcessInstanceId();//当前活动节点名称（任务名称）String currentActName = task.getName();//获取当前操作人姓名SysUser loginuser = iFlowThirdService.getLoginUser();String name = loginuser.getRealname();String type = FlowComment.JUMP.getType();//添加跳转意见 name + "将任务跳转到【" + targetActName + "】，跳转原因：" + comment + ";";taskService.addComment(task.getId(), processInstanceId, type,"当前任务["+currentActName +"]由" + name + "跳转到[" + flowTaskVo.getTargetActName() + "]，跳转原因：" + flowTaskVo.getComment());//执行跳转操作runtimeService.createChangeActivityStateBuilder().processInstanceId(processInstanceId).moveActivityIdTo(currentActId, flowTaskVo.getTargetActId()).changeState();}@Overridepublic Result userTaskList(FlowTaskVo flowTaskVo) {List<UserTaskVo> resultList = new ArrayList<UserTaskVo>();// 当前任务 taskTask task = taskService.createTaskQuery().taskId(flowTaskVo.getTaskId()).singleResult();// 获取流程定义信息ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery().processDefinitionId(task.getProcessDefinitionId()).singleResult();//根据流程定义获取deploymentString deploymentId = processDefinition.getDeploymentId();Deployment deployment = repositoryService.createDeploymentQuery().deploymentId(deploymentId).singleResult();if (ObjectUtil.isEmpty(deployment)) {throw new FlowableException("流程还没布置");}//获取bpmnModel并转为modelNodeBpmnModel bpmnModel = repositoryService.getBpmnModel(processDefinition.getId());//获取主流程Process mainProcess = bpmnModel.getMainProcess();//获取用户任务节点类型，深入子流程mainProcess.findFlowElementsOfType(UserTask.class, true).forEach(userTask -> {UserTaskVo userTaskResult = new UserTaskVo();userTaskResult.setId(userTask.getId());userTaskResult.setProcessDefinitionId(processDefinition.getId());userTaskResult.setName(userTask.getName());resultList.add(userTaskResult);});return Result.OK(resultList);}
