对于List＜Map＞集合里面的数据按照【时间】等字段排序

// 准备一个集合
List<Map<String, Object>> resList= Lists.newArrayList();
Map<String, Object> map1 = Maps.newHashMap();
map1.put("name","张三"); 
map1.put("receiving_time","2019-05-04"); 
resList.add(map1);

Map<String, Object> map2 = Maps.newHashMap();
map2 .put("name","李四"); 
map2 .put("receiving_time","2019-05-08"); 
resList.add(map2);

// 按照时间倒叙
SimpleDateFormat sd = new SimpleDateFormat("yyyy-MM-dd HH:mm");
for (int i = 0; i < resList.size(); i++){
    
    
    for (int j = resList.size() - 1; j > i; j--){
    
    
        if(!StringUtils.isEmpty(resList.get(j).get("receiving_time"))){
    
    
            Date dates = sd.parse(resList.get(j).get("receiving_time").toString());
            Date date = sd.parse(resList.get(j - 1).get("receiving_time").toString());
            
            //互换位置
            if (dates.compareTo(date) > 0){
    
    
                Map<String, Object> tempMap = resList.get(j);
                resList.set(j, resList.get(j-1));
                resList.set(j-1, tempMap);
            }
        }
    }
}
