                var array2=[]
                for (var i=0;i

后台 返回 Json 

  /**
     * 
     * 返回需要的数据
     * @return
     */
    @RequestMapping("getTbHadoopQueueTime")
    @ResponseBody
    public JsonObject getTbHadoopQueue() {
        List monitorQueues = monitorHadoopUserService.tbMonitorQueue();
        String tbQueueTime = null;
        List t = new ArrayList();
        for (MonitorQueue monitorQueue : monitorQueues) {
            Date createTime = monitorQueue.getCreate_time();
            SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm");
            tbQueueTime = dateFormat.format(createTime);
            t.add(tbQueueTime);
        }
        return JsonObject.success(t);
    }

    /**
     *  监控
     * @return
     */
    @RequestMapping("getTbHadoopQueues")
    @ResponseBody
    public JsonObject getTbHadoopQueues() {
        List monitorQueues = monitorHadoopUserService.tbMonitorQueue();
        List list = new ArrayList();
        for (MonitorQueue monitorQueue : monitorQueues) {
            Integer cpu = monitorQueue.getCpu();
            Integer memory = monitorQueue.getMemory();
            Integer jobNumber = monitorQueue.getJob_number();
            list.add(cpu);
            list.add(memory);
            list.add(jobNumber);
        }
        return JsonObject.success(list);
    }

 后台 返回数据 ，前端 接收到 转为数组 在填充 到 Series里面 就ok了
