redisTemplate 實現有序集合排序

存入數據代碼
/*
  redisTemplate.opsForZSet().add(K key, V value, double score);*/
  String redisKey = "yourKey";
  Long itemId = 100;
  Long itemId = 101;
  // 存放數據
  redisTemplate.opsForZSet().add(redisKey , itemId, System.currentTimeMillis());
  redisTemplate.opsForZSet().add(redisKey , itemId2, System.currentTimeMillis());

取值數據代碼，取值爲yourKey的數據按照得分的降序排列取前十
/*
  redisTemplate.opsForZSet().reverseRange(K key, long start, long end);*/
  String redisKey = "yourKey";
  Set<Object> reverseRange = redisTemplate.opsForZSet().reverseRange(redisKey , 0, 9);
