工作流在 UserTask 处暂停。设置本地和流程变量后，我尝试了TaskService.complete(task.getId())。当离开该方法时，它会回滚。但是，没有任何信息可以让我看到异常的实际原因。
我正在使用 Spring-boot 1.5.10.RELEASE
下面是我的 maven for activiti 的快照：
<dependency>
<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>
这是 bpmn 文件。我已经成功启动了一个新进程，它可以很好地执行前 2 个“stLockCourseMarks”服务任务和“IsCourseMarkLocked”专用网关。所以它在“Moderation” UserTask 处暂停：

下面是尝试完成 utModeration UserTask 的方法。但是，我在这里遇到回滚。
@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;
}
