Spring-boot Activiti TaskUser 執行TaskService.complete 時導致回滾

Question

工作流在 UserTask 處暫停。 設置本地和流程變量后，我嘗試TaskService.complete(task.getId())。 當離開方法時，它回滾。 但是，沒有任何信息可以讓我看到異常中的實際原因。

我正在使用 Spring-boot 1.5.10.RELEASE

下面是我的 Maven 的 Activiti 快照：

            <groupId>org.activiti</groupId>
            <artifactId>spring-boot-starter-basic</artifactId>
            <version>5.17.0</version>
        </dependency>
        <dependency>
            <groupId>org.activiti</groupId>
            <artifactId>spring-boot-starter-jpa</artifactId>
            <version>5.17.0</version>
        </dependency>

這是 bpmn 文件。 我已經成功啟動了一個新進程，該進程對前 2 個“stLockCourseMarks”服務任務和“IsCourseMarkLocked”專用網關執行得很好。 所以它暫停在“審核”用戶任務：

下面是嘗試完成 utModeration UserTask 的方法。 但是，我在這里遇到回滾。

@Transactional(readOnly = false, propagation=Propagation.REQUIRED)
    public List<String> approveCourseMarks(CourseMarksApprovalDto dto, AppUser auser) 
    throws SmsException {

        if (dto == null) throw new SmsException("No approval received","Invalid Approval");
        List<String> errors = new ArrayList<String>();

        if (dto == null || dto.getTaskId() == null) throw new SmsException("No task information received. Unable to proceed.","Invalid Task");
        System.out.println("=== dto="+dto);
        Task task = wfTaskService.createTaskQuery()
                        .taskId(dto.getTaskId())
                        .active()
                        .singleResult();

        if (task == null) {
            errors.add("Course " + dto.getCourse().getFullname() 
                                 + " workflow task is not available to processing. It may already been approved/rejected.");
        }

            Map<String, Object> localVars = new HashMap<String,Object>();

            localVars.put(CourseMarksWorkflowService.VAR_REMARKS, dto.getRemarks());
            localVars.put(CourseMarksWorkflowService.CONDITION_APPROVAL_STATUS, dto.getApprovalStatus());
            localVars.put(CourseMarksWorkflowService.VAR_ACTUAL_AO_ID, auser.getId());
            wfTaskService.setVariablesLocal(task.getId(), localVars);
            wfRuntimeService.setVariable(task.getProcessInstanceId(), CourseMarksWorkflowService.CONDITION_APPROVAL_STATUS, dto.getApprovalStatus());

            wfTaskService.complete(task.getId());

        return errors;
    }

以下是我遇到的異常：

問題的原因可能是什么？ 謝謝。

Answer 1

設法解決了它； 需要將事務進度從REQUIRES更改為REQUIRES_NEW 。 這是方法更改的注釋：

不知道為什么這可以解決問題。 如果有人知道原因，將有興趣知道。
