activiti 定时边界相关

在activiti开发中经常会碰到节点之间互相跳转的需求，正常的跳转，用下面代码即可完成：

public class JumpCmd implements Command<Object> {    private String            activityId;    private String            processInstanceId;    @Autowired    private ManagementService managementService;    @Autowired    private RuntimeService    runtimeService;    public JumpCmd(String processInstanceId, String activityId){        this.activityId = activityId;        this.processInstanceId = processInstanceId;    }    public Object execute(CommandContext commandContext) {        List<Execution> executionList = runtimeService.createExecutionQuery().executionId(processInstanceId).list();        for (Execution execution : executionList) {            String executionId = execution.getId();            managementService.executeCommand(new EndEntityCmd(processInstanceId, executionId, null));        }        ExecutionEntity executionEntity = commandContext.getExecutionEntityManager().findExecutionById(processInstanceId);        ProcessDefinitionImpl processDefinition = executionEntity.getProcessDefinition();        ActivityImpl activity = processDefinition.findActivity(activityId);        executionEntity.executeActivity(activity);        return null;    }}

但是这里会有个问题 ，当跳转到带有定时边界任务的task时，定时job没有在job表中生成，做下面修改后即可：

 public Object execute(CommandContext commandContext) {        List<Execution> executionList = ActivitiUtil.runtimeService.createExecutionQuery().processInstanceId(processInstanceId).list();        for (Execution execution : executionList) {            String executionId = execution.getId();            ActivitiUtil.managementService.executeCommand(new EndEntityCmd(processInstanceId, executionId, null));        }        ExecutionEntity executionEntity = commandContext.getExecutionEntityManager().findExecutionById(processInstanceId);        ProcessDefinitionImpl processDefinition = executionEntity.getProcessDefinition();        ActivityImpl activity = processDefinition.findActivity(activityId);        InterpretableExecution propagatingExecution = null;        if (activity.isScope()) {          propagatingExecution = (InterpretableExecution) executionEntity.createExecution();          propagatingExecution.setActivity(activity);          propagatingExecution.setTransition(executionEntity.getTransition());          executionEntity.setTransition(null);          executionEntity.setActivity(null);          executionEntity.setActive(false);          propagatingExecution.initialize();          propagatingExecution.performOperation(AtomicOperation.TRANSITION_NOTIFY_LISTENER_START);        } else {//          propagatingExecution = executionEntity;            executionEntity.executeActivity(activity);        }//        propagatingExecution.performOperation(AtomicOperation.TRANSITION_NOTIFY_LISTENER_START);        return null;    }
