 *  啟動流程實例，添加進businessKey

 *  本質：act_ru_execution表中的businessKey的字段要存入業務標識
 */

    public static void main(String[] args) {
        //1.得到ProcessEngine對象
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

        //2.得到RuntimeService對象
        RuntimeService runtimeService = processEngine.getRuntimeService();

        //3.啟動流程實例,同時還要指定業務標識businessKey  它本身就是請假單的id
        //第一個參數：是指流程定義key
        //第二個參數：業務標識businessKey
        ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("holiday", "1001");

        //4.輸出processInstance相關的屬性,取出businessKey使用:processInstance.getBusinessKey()
        System.out.println(processInstance.getBusinessKey());
