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;
        }
