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);

}
