• 2.审批

1. 查询登录用户的待办任务

private List<Task> queryMyTasks(){
	String username = SecurityUtils.getUsername();
	String roles = String.join(",", tokenService.getLoginUser().getRoles());
	//待办
	List<String> assignedTaskIds = taskService.createTaskQuery()
			.taskAssignee(username)
		  //  .taskCandidateOrAssigned(username)
			.list().stream().map(TaskInfo::getId).collect(Collectors.toList());
	//待签收
	List<String> waitClaimTaskIdsByCandidateUser =  actRuIdentityLinkMapper.queryTaskIdsByCandidateUser(username);
	List<String> waitClaimTaskIdsByCandidateGroup =  actRuIdentityLinkMapper.queryTaskIdsByCandidateGroup(roles);
	//待签收任务合并去重
	waitClaimTaskIdsByCandidateUser.removeAll(waitClaimTaskIdsByCandidateGroup);
	waitClaimTaskIdsByCandidateUser.addAll(waitClaimTaskIdsByCandidateGroup);

	//待办、待签收合并去重
	assignedTaskIds.removeAll(waitClaimTaskIdsByCandidateUser);
	assignedTaskIds.addAll(waitClaimTaskIdsByCandidateUser);

	return assignedTaskIds.stream().map(taskId -> taskService.createTaskQuery().taskId(taskId).singleResult()).collect(Collectors.toList());
}

2.审批

注：查询待办任务时并没有使当前用户进行任务拾取，而是等他办理审批时确定拾取人是当前用户

如果是申请用户调整申请，则允许修改实体类+审批(对于申请用户并没有审批的功能，只是判断他是否继续申请还是取消申请)。如果是继续申请，则点击同意并修改实体类；取消申请则没必要对实体类进行修改了

public AjaxResult formDataSave(@PathVariable("taskID") String taskID,
                                   @RequestBody   List<ActWorkflowFormDataDTO> formData ) throws ParseException {
	return toAjax(actTaskService.formDataSave(taskID, formData));
}

public int formDataSave(String taskID, List<ActWorkflowFormDataDTO> awfs) throws ParseException {
//        Task task = taskRuntime.task(taskID);
	Task task = taskService.createTaskQuery().taskId(taskID).singleResult();
	ProcessInstance processInstance = runtimeService.createProcessInstanceQuery().processInstanceId(task.getProcessInstanceId()).singleResult();

	Boolean hasVariables = false;//没有任何参数
	HashMap<String, Object> variables = new HashMap<String, Object>();
	//前端传来的字符串，拆分成每个控件
	List<ActWorkflowFormData> acwfds = new ArrayList<>();
	for (ActWorkflowFormDataDTO awf : awfs) {
		ActWorkflowFormData actWorkflowFormData = new ActWorkflowFormData(processInstance.getBusinessKey(),awf, task);
		acwfds.add(actWorkflowFormData);
		//构建参数集合
		if(!"f".equals(awf.getControlIsParam())) {
				variables.put(awf.getControlId(), awf.getControlValue());
				hasVariables = true;
		}
	}
	if (task.getAssignee() == null) {
//            taskService.claim(TaskPayloadBuilder.claim().withTaskId(task.getId()).build());
		//拾取任务
		taskService.claim(task.getId(),SecurityUtils.getUsername());
	}
	if (hasVariables) {
		//带参数完成任务
  /*      taskRuntime.complete(TaskPayloadBuilder.complete().withTaskId(taskID)
				.withVariables(variables)
				.build());*/
		taskService.complete(taskID,variables);
	} else {
	   /* taskRuntime.complete(TaskPayloadBuilder.complete().withTaskId(taskID)
				.build());*/
		taskService.complete(taskID);
	}
	//

	//写入数据库 这张表是自己设计的，在查看历史任务是会用到
	return actWorkflowFormDataService.insertActWorkflowFormDatas(acwfds);
