获取指定时间点的时间戳

首先引入工具类import java.util.Calendar;

再设置指定时间

            

Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, 8);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);

再获取该指定时间的时间戳

int dz =(int)(cal.getTimeInMillis());

java里面获取对象

dto = storeService.getDeviceCount(storeId, region, "1");
HashMap<String, Object> map = (HashMap<String, Object>)dto.getData();

 

再从获取的对象里取值

dataList = (List<Map<String,Object>>)map.get("list");
countTime = ((String) map.get("countTime")).replaceAll("\\-","");

 

直接获取数组

dto = storeService.getDeviceCount(storeId, region, "2");
dataList = (List<Map<String, Object>>)dto.getData();
