我是靠谱客的博主妩媚云朵，最近开发中收集的这篇文章主要介绍基于jeecgboot的flowable流程增加节点表单的支持（三），觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

在流程流转过程中增加节点表单的后端修改

8、complete的修改

主要增加下面方法，就是有任务节点表单的时候，complete需要取出这个值来，之后要进行下面的complete，特别是需要true参数，否则会有问题，所以对原先多实例approval处理进行另外处理，不在这里进行处理了

/**
* 任务节点有表单的操作
*
* @param taskVo
*/
private void taskFormCompete(FlowTaskVo taskVo) {
if(taskVo.getValues().containsKey("taskformvalues")) {//有任务节点表单
@SuppressWarnings("unchecked")
Map<String , Object> taskformvalues = (Map<String, Object>) taskVo.getValues().get("taskformvalues");
taskService.complete(taskVo.getTaskId(),taskformvalues, true);//保存taskid到变量表里
}
else {
taskService.complete(taskVo.getTaskId());
}
}

9、flowrecord的修改，主要增加下面部分，就是历史表单参数与历史表单数据

// 获取历史任务节点表单数据值
List<HistoricVariableInstance> listHistoricVariableInstance = historyService.createHistoricVariableInstanceQuery()
.processInstanceId(procInsId)
.taskId(histIns.getTaskId())
.list();
Map<String, Object> variables = new HashedMap<String, Object>();
Map<String, Object> formconf = new HashedMap<String, Object>();
for(HistoricVariableInstance historicVariableInstance:listHistoricVariableInstance) {
variables.put(historicVariableInstance.getVariableName(), historicVariableInstance.getValue());
}
formconf.put("formValue", variables);
// 获取历史任务节点表单参数
if(Objects.nonNull(histIns.getTaskId())) {
HistoricTaskInstance taskIns = historyService.createHistoricTaskInstanceQuery()
.taskId(histIns.getTaskId())
.includeIdentityLinks()
.includeProcessVariables()
.includeTaskLocalVariables()
.finished()
.singleResult();
if (Objects.nonNull(taskIns)) {
{
String formId = taskIns.getFormKey();
SysForm sysForm = sysDeployFormService.selectCurSysDeployForm(formId, deployId, taskIns.getTaskDefinitionKey());
if (Objects.nonNull(sysForm)) {
formconf.put("config", JSONObject.parseObject(sysForm.getFormContent()).get("config"));
formconf.put("list", JSONObject.parseObject(sysForm.getFormContent()).get("list"));
}
}
}
}
flowTask.setTaskFormValues(formconf);
hisFlowList.add(flowTask);
}
}
map.put("flowList", hisFlowList);
}
// 获取初始化自定义表单
if(StringUtils.isNotBlank(businessKey)) {
FlowMyBusiness business = flowMyBusinessService.getByDataId(businessKey);
String serviceImplName = business.getServiceImplName();
FlowCallBackServiceI flowCallBackService = (FlowCallBackServiceI) SpringContextUtils.getBean(serviceImplName);
// 流程处理完后，进行回调业务层
if (flowCallBackService!=null){
Object businessDataById = flowCallBackService.getBusinessDataById(businessKey);
map.put("formData",businessDataById);
map.put("routeName", business.getRouteName());
}
}
else {
if (StringUtils.isNotBlank(deployId)) {
//获取当前节点的初始化表单
if(Objects.nonNull(taskId)) {
HistoricTaskInstance taskIns = historyService.createHistoricTaskInstanceQuery()
.taskId(taskId)
.includeIdentityLinks()
.includeProcessVariables()
.includeTaskLocalVariables()
.singleResult();
if (Objects.nonNull(taskIns)) {
String formId = taskIns.getFormKey();
SysForm sysForm = sysDeployFormService.selectCurSysDeployForm(formId, deployId, taskIns.getTaskDefinitionKey());
if (Objects.nonNull(sysForm)) {
map.put("taskFormData", JSONObject.parseObject(sysForm.getFormContent()));
}
}
}
else {
SysForm sysForm = sysDeployFormService.selectSysDeployFormByDeployId(deployId);
if (Objects.isNull(sysForm)) {
return Result.error("请先配置流程表单");
}
map.put("formData", JSONObject.parseObject(sysForm.getFormContent()));
}
}
