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
