RedisTemplate常用集合使用说明-opsForZSet(六)

基础配置介绍已经在前面的《RedisTemplate常用集合使用说明(一)]》中已经介绍了，现在我们直接介绍opsForZSet()方法的使用：

1、add(K key, V value, double score)

添加元素到变量中同时指定元素的分值。

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)

获取变量指定区间的元素。

Set zSetValue = redisTemplate.opsForZSet().range("zSetValue",0,-1);
System.out.println("通过range(K key, long start, long end)方法获取指定区间的元素:" + zSetValue);

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

用于获取满足非score的排序取值。这个排序只有在有相同分数的情况下才能使用，如果有不同的分数则返回值不确定。

RedisZSetCommands.Range range = new RedisZSetCommands.Range();
//range.gt("A");
range.lt("D");
zSetValue = redisTemplate.opsForZSet().rangeByLex("zSetValue", range);
System.out.println("通过rangeByLex(K key, RedisZSetCommands.Range range)方法获取满足非score的排序取值元素:" + zSetValue);

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

用于获取满足非score的设置下标开始的长度排序取值。

RedisZSetCommands.Limit limit = new RedisZSetCommands.Limit();
limit.count(2);
//起始下标为0
limit.offset(1);
zSetValue = redisTemplate.opsForZSet().rangeByLex("zSetValue", range,limit);
System.out.println("通过rangeByLex(K key, RedisZSetCommands.Range range, RedisZSetCommands.Limit limit)方法获取满足非score的排序取值元素:" + zSetValue);

ZSetOperations.TypedTuple<Object> typedTuple2 = new DefaultTypedTuple<Object>("F",7.0);
ZSetOperations.TypedTuple<Object> typedTuple3 = new DefaultTypedTuple<Object>("G",5.0);
Set<ZSetOperations.TypedTuple<Object>> typedTupleSet = new HashSet<ZSetOperations.TypedTuple<Object>>();
typedTupleSet.add(typedTuple1);
typedTupleSet.add(typedTuple2);
typedTupleSet.add(typedTuple3);
redisTemplate.opsForZSet().add("typedTupleSet",typedTupleSet);
zSetValue = redisTemplate.opsForZSet().range("typedTupleSet",0,-1);
System.out.println("通过add(K key, Set<ZSetOperations.TypedTuple<V>> tuples)方法添加元素:" + zSetValue);

6、rangeByScore(K key, double min, double max)

7、rangeByScore(K key, double min, double max,long offset, long count)

根据设置的score获取区间值从给定下标和给定长度获取最终值。
