五种数据结构

1、string

2、hash（类似map）

3、list

4、set

5、有序set

jedisClient.set("redis_test", "value");
        String redisStr = jedisClient.get("redis_test");
        jedisClient.hset("rule","name","chi.zhang04");
        jedisClient.hset("rule","age","27");
        jedisClient.hset("rule","sex","male");
        Map<String,String> map = jedisClient.hgetall("rule");
        jedisClient.lpush("list", "l1","l2","l2","l3");
        List<String> list = jedisClient.lrange("list", 0l, 3l);

        jedisClient.sadd("redis_set", "set1", "set2", "set3","set3");
        Set<String> str = jedisClient.smembers("redis_set");
        System.out.println(str);
        Map<String,Double> maps = Maps.newHashMap();
        maps.put("m1", 22d);
        maps.put("m2", 23d);
        maps.put("m3", 2d);
        maps.put("m4", 77d);
        maps.put("m7", 78d);
        jedisClient.zadd("zsort", maps);
        Set<String> strings = jedisClient.zrevrangeByScore("zsort", 100d,2d);
        System.out.println(strings);
