activiti 6.0.0.4版本判斷當前會簽的UserTask是否為多實例任務

/**
 * @param task 任務節點id
 * @return boolean (這里用一句話描述返回結果說明)
 * @Title: isMultiInstance 是否為多實例節點
 * @Description: 是否為多實例節點
 */

private boolean isMultiInstance(TaskEntity task) {
    // 獲取流程定義id
    boolean flag = false;
    String processDefinitionId = task.getProcessDefinitionId();
    Process process = ProcessDefinitionUtil.getProcess(processDefinitionId);
    FlowElement flowElement = process.getFlowElement(task.getTaskDefinitionKey());
    // 根據活動id獲取活動實例
    if (flowElement instanceof UserTask) {
        UserTask userTask = (UserTask) flowElement;
        if (userTask.getBehavior() instanceof ParallelMultiInstanceBehavior) {
            ParallelMultiInstanceBehavior behavior = (ParallelMultiInstanceBehavior) userTask.getBehavior();
            if (behavior != null && behavior.getCollectionExpression() != null) {
                flag = true;
            }
        }
    }
    return flag;
}

當前的TaskEntity在命令模式中使用上下文commandcontext對象可以獲取task的管理對象
