案例demo的功能是文章排名等，整个demo的总页面如下。准备工作首先定义一个keyprivatestaticfinalStringZSET_KEY="articleList"，用于存放文章；redis操作对象privateRedisTemplateredisTemplate;//string命令操作对象privateValueOperationsvalueOperations;//zset命令操作对象privateZSetOperationszSetOperations;在行动中）。列表查询@RequestMapping(value="/getList/{sortType}",method=RequestMethod.GET)publicSetgetList(@PathVariableStringsortType){//如果没有数据，添加10条数据if(zSetOperations.size(ZSET_KEY)==0){for(inti=1;i<=10;i++){zSetOperations.add(ZSET_KEY,"文章:"+i,(int)(Math.random()*10+i));}}//ASC根据分数从小到大排序，DESC反之if("ASC".equals(sortType)){returnzSetOperations.rangeWithScores(ZSET_KEY,0,-1);}else{returnzSetOperations.reverseRangeWithScores(ZSET_KEY,0,-1);}}这里为了省去逐条添加数据的麻烦，在获取列表数据的时候加入了判断。当文章数据为0时，默认添加10条数据，设置随机分加索引。然后根据url中的参数sortType判断返回的数据是按分数升序还是降序排序。函数效果如下。命令介绍likeordislike如下,member,1);}else{zSetOperations.incrementScore(ZSET_KEY,member,-1);}returntrue;}根据类型判断是否加分或减分，当type为UP时表示喜欢，当为other(DOWN)，表示向下。作用及效果如下命令引入排名升序java代码如下@RequestMapping(value="/rank/{type}/{member}",method=RequestMethod.GET)publicLongrank(@PathVariableStringmember,@PathVariableStringtype){Longrank=null;if("ASC".equals(type)){rank=zSetOperations.rank(ZSET_KEY,member);}else{rank=zSetOperations.reverseRank(ZSET_KEY,member);}returnrank;}根据类型决定升序还是降序，如果是ASC，调用rank方法获取升序，其他调用reverseRank获取降序。类似于下面的redis命令ZRANKarticleList"第1条"ZREVRANKarticleList"第1条"页面效果图下面的命令介绍其他获取属性的命令ZCARD命令返回key的有序集合元素的个数。ZCARD键返回值：当key存在时，返回有序集合中元素的个数，否则返回0。redis客户端执行的命令如下zaddzCardKey1onezcardzCardKey下面是java代码@TestpublicvoidzCard(){jedis.zadd("zCardKey",1,"one");jedis.zadd("zCardKey",2,"two");System.out.println(jedis.zcard("zCardKey"));System.out.println(zSetOperations.size("zCardKey"));}ZCOUNT命令返回有序集合key，score值介于min和max（默认包括score值等于min或max的成员数）。ZCOUNTkeyminmax返回值：指定分数范围内的元素个数。redis客户端执行的命令如下：zaddzCountKey1one2two3three4fourzcountzCountKey23执行结果如下：下面是java代码@TestpublicvoidzCount(){jedis.zadd("zCountKey",1,"one");jedis.zadd("zCountKey",2,"二");jedis.zadd("zCountKey",3,"three");jedis.zadd("zCountKey",4,"four");System.out.println(jedis.zcount("zCountKey",2,3));System.out.println(zSetOperations.count("zCountKey",2,3));}ZLEXCOUNT命令计算有序集合中指定成员中的成员个数（按照成员字典的正序排序），其中可以用-和+表示score的最小值和最大值ZLEXCOUNTkeyminmaxredis客户端执行的命令如下ZADDzLexCountKey2"b"1"a"3"c"5"e"4"d"ZLEXCOUNTzLexCountKey-+ZLEXCOUNTzLexCountKey-+ZLEXCOUNTzLexCountKey[b[d执行结果如下下面是java代码@TestpublicvoidzLexCount(){zSetOperations.add("zLexCountKey","b",2);zSetOperations.add("zLexCountKey","a",1);zSetOperations.add("zLexCountKey","c",3);zSetOperations.add("zLexCountKey","e";,5);zSetOperations.add("zLexCountKey","d",4);System.out.println(jedis.zlexcount("zLexCountKey","-","+"));System.out.println(jedis.zlexcount("zLexCountKey","[b","[d"));}ZSCORE命令返回有序集合key中member成员的分值ZSCOREkeymember返回值：member成员的分值是redis客户端执行命令如下zaddzScoreKey1oneZSCOREzScoreKeyone下面是java代码@TestpublicvoidzScore(){jedis.zadd("zScoreKey",1,"one");System.out.println(jedis.zscore("zScoreKey",“一个”））；系统。out.println(zSetOperations.score("zScoreKey","one"));}获取成员ZRANGEBYLEX命令返回指定成员范围内的成员，按照成员字典的正序排序。https://redis.io/commands/zrangebylexZRANGEBYLEXkeyminmax[LIMIToffsetcount]返回值：指定成员范围的元素列表。redis客户端执行的命令如下：ZADDzRangeByLexKey0ba0a0ab0aa0bZRANGEBYLEXzRangeByLexKey-+ZRANGEBYLEXzRangeByLexKey[aa(ba(ba)执行结果如下下面是java代码@TestpublicvoidzRangeByLex(){zSetOperations.add("zRangeByLexKeyz","SetOperations",0);.add("a",0);zSetOperations.add("zRangeByLexKey","ab",0);zSetOperations.add("zRangeByLexKey","aa",0);zSetOperations.add("zRangeByLexKey","b",0);System.out.println(jedis.zrangeByLex("zRangeByLexKey","-","+"));RedisZSetCommands.Rangerange=newRedisZSetCommands.Range();range.gte("aa");范围。lt("ba");System.out.println(zSetOperations.rangeByLex("zRangeByLexKey",range));}ZRANGEBYSCORE命令获取得分在范围内的数据。min和max可以是-inf和+infZRANGEBYSCOREkeyminmax[WITHSCORES]``[LIMIToffsetcount]redis客户端执行的命令如下："zRangeByScoreKey","ba",1);zSetOperations.add("zRangeByScoreKey","a",2);zSetOperations.add("zRangeByScoreKey","ab",3);zSetOperations.add("zRangeByScoreKey","aa",4);zSetOperations.add("zRangeByScoreKey","b",5);System.out.println(jedis.zrangeByScore("zRangeByScoreKey","-inf","+inf"));RedisZSetCommands.Rangerange=newRedisZSetCommands.Range();System.out.println(zSetOperations.rangeByScore("zRangeByScoreKey",2,4));}移除相关命令ZREM命令ZREMkeymember[member...]返回值：有序集合的个数在redis客户端删除成员执行如下命令：ZADDzRemKey1"one"2"two"3"three"ZREMzRemKeyoneZRANGEzRemKey0-1的执行结果如下。下面是java代码@TestpublicvoidzRem(){zSetOperations.add("zRemKey","one",1);zSetOperations.add("zRemKey","two",2);zSetOperations.add("zRemKey","三",3);//jedis.zrem("zRemKey","one");zSetOperations.remove("zRemKey","one");System.out.println(zSetOperations.range("zRemKey",0,-1));}交集和并集ZINTERSTORE命令计算给定numkeys有序集的交集，并将结果放在目标中。在指定要计算的键和其他参数之前，必须给出键的个数（numberkeys）。默认情况下，结果中元素的分数是排序集中该元素分数的总和，前提是该元素存在于这两个排序集中。因为交集要求其成员必须是每个给定有序集合的成员，所以结果集中每个元素的得分等于输入有序集合的数量。有关WEIGHTS和AGGREGATE参数的说明，请参阅ZUNIONSTORE命令。如果目标存在，则将其覆盖。ZINTERSTOREdestinationnumkeyskey[key...][WEIGHTSweight[weight...]][AGGREGATESUM|MIN|MAX]返回值：结果有序集中目的地的元素个数。redis客户端执行的命令如下：ZADDzInterStoreKey11"one"2"two"ZADDzInterStoreKey21"o
