activiti工作流获取出线（outgoingTransitions）

首先上代码：

/**     * 根据processInstanceId获取出线     * （获取本节点后面的所有出线）     * @param taskId     * @return     */    public List<String> getFlows(String processInstanceId) {        Task task = engine.getTaskService().createTaskQuery().processInstanceId(processInstanceId).singleResult();        ExecutionEntity execution = (ExecutionEntity) engine.getRuntimeService().createExecutionQuery().executionId(task.getExecutionId()).singleResult();        String activitiId = execution.getActivityId();        logger.info("根据taskid获取activitiId：" + activitiId);        String processDefinitionId = engine.getHistoryService().createHistoricProcessInstanceQuery().processInstanceId(task.getProcessInstanceId()).singleResult().getProcessDefinitionId();        ProcessDefinitionEntity processDefinitionEntity = (ProcessDefinitionEntity) ((RepositoryServiceImpl) engine.getRepositoryService()).getDeployedProcessDefinition(processDefinitionId);        List<ActivityImpl> activities = processDefinitionEntity.getActivities();        logger.info("根据processInstanceId获取本流程图的所有节点");        List<PvmTransition> `outgoingTransitions` = new ArrayList<PvmTransition>();        List<String> messageList = new ArrayList<String>();        for (ActivityImpl activityImpl : activities) {            if (activityImpl.getId().equals(activitiId)) {                outgoingTransitions = activityImpl.getOutgoingTransitions();                for (PvmTransition pvmTransition : outgoingTransitions) {                    messageList.add(pvmTransition.getProperty("name").toString());                }                logger.info("获取本节点的所有出线");            }        }        return messageList;    }

上述代码就是获取一个节点后面的出线上的name（也就是图二线上的字）。

List<PvmTransition> `outgoingTransitions` = new ArrayList<PvmTransition>();

就是出线信息，读者可以查看这个PvmTransition对象，查看具体信息
