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);

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。
zSetValue = redisTemplate.opsForZSet().rangeByScore("zSetValue",1,5,1,3);

Object value = typedTuple.getValue();
double score = typedTuple.getScore();
System.out.println("通过rangeWithScores(K key, long start, long end)方法获取RedisZSetCommands.Tuples的区间值:" + value + "---->" + score );
}
