基礎(chǔ)配置介紹已經(jīng)在前面的《RedisTemplate常用集合使用說明(一)]》中已經(jīng)介紹了，現(xiàn)在我們直接介紹opsForZSet()方法的使用：

1、add(K key, V value, double score)

添加元素到變量中同時指定元素的分值。

redisTemplate.opsForZSet().add("zSetValue","A",1); redisTemplate.opsForZSet().add("zSetValue","B",3); redisTemplate.opsForZSet().add("zSetValue","C",2); redisTemplate.opsForZSet().add("zSetValue","D",5);

2、range(K key, long start, long end)

? 獲取變量指定區(qū)間的元素。

?

Set zSetValue = redisTemplate.opsForZSet().range("zSetValue",0,-1); System.out.println("通過range(K key, long start, long end)方法獲取指定區(qū)間的元素:" + zSetValue);

3、rangeByLex(K key, RedisZSetCommands.Range range)

用于獲取滿足非score的排序取值。這個排序只有在有相同分?jǐn)?shù)的情況下才能使用，如果有不同的分?jǐn)?shù)則返回值不確定。

RedisZSetCommands.Range range = new RedisZSetCommands.Range(); //range.gt("A"); range.lt("D"); zSetValue = redisTemplate.opsForZSet().rangeByLex("zSetValue", range); System.out.println("通過rangeByLex(K key, RedisZSetCommands.Range range)方法獲取滿足非score的排序取值元素:" + zSetValue);

4、rangeByLex(K key, RedisZSetCommands.Range range, RedisZSetCommands.Limit limit)

? 用于獲取滿足非score的設(shè)置下標(biāo)開始的長度排序取值。

RedisZSetCommands.Limit limit = new RedisZSetCommands.Limit(); limit.count(2); //起始下標(biāo)為0 limit.offset(1); zSetValue = redisTemplate.opsForZSet().rangeByLex("zSetValue", range,limit); System.out.println("通過rangeByLex(K key, RedisZSetCommands.Range range, RedisZSetCommands.Limit limit)方法獲取滿足非score的排序取值元素:" + zSetValue);

5、add(K key, Set<ZSetOperations.TypedTuple> tuples)
