Redis工具类（redisTemplate）以及 redisTemplate 的用法
redisTemplate 的用法以及与Jedis的对照
| 操作 |
Jedis |
StringRedisTemplate |
| String |
|
|
| 设置 |
set(“k”,“v”) |
template.opsForValue().set(“k”,“v”) |
| 获取 |
get(“k”) |
template.opsForValue().get(“k”) |
| 增1 |
incr(“k”) |
template.boundValueOps(“k”).increment(1) |
| 减1 |
decr(“k”) |
template.boundValueOps(“k”).increment(-1) |
| 设置时间 |
setex(“k”,seconds,“v”) |
template.opsForValue().set(“k”,“v”,20, TimeUnit.SECONDS) |
| 不存在 就设置 |
setnx(“k”,“v”) |
template.opsForValue().setIfAbsent(“k”, “v”) |
| 获取过期时间 |
ttl(“k”) |
template.getExpire(“k”) |
| 删除 |
del(“k”) |
template.delete(“k”) |
| Hash |
|
|
| 设置 |
jedis.hset(“pig”,“name”,“peiqi”); |
template.opsForHash().put(“pig”,“name”,“peiqi”) |
| 获取 |
jedis.hget(“pig”,“name”) |
template.opsForHash().get(“pig”, “name”) 获取所有template.opsForHash().values(“pig”) |
| 删除 |
jedis.hdel(“pig”,“name”) |
template.opsForHash().delete(“pig”,“name”) |
| 判断是否存在 |
jedis.hexists(“pig”,“name”) |
template.opsForHash().hasKey(“pig”,“name”) |
| List |
左/右不做区分 |
|
| 添加 |
rpush(“k”,“v”) |
template.opsForList().rightPush(“k”,“v”) |
| 移出 |
rpop(“list”) |
template.opsForList().rightPop(“k”) |
| 长度 |
llen(“k”) |
template.opsForList().size(“k”) |
| 获取 |
lrange(“list”,0,-1) //-1全部 |
template.opsForList().range(“list”, 0, -1) |
| Set |
|
|
| 添加 |
sadd(“k”,“v”) |
template.opsForSet().add(“k”,“v”) |
| 值移除 |
srem(“k”,“v”) |
template.opsForSet().remove(“k”,“v”) |
| 直接移 |
spop(“k”) |
template.opsForSet().pop(“k”) |
| 长度 |
scard(“k”) |
template.opsForSet().size(“k”) |
| 交集 |
sinter(“k1”,“k2” ) |
template.opsForSet().intersect(“k”, “k2”) |
| 并集 |
sunion(“k1”,“k2” ) |
template.opsForSet().union(“k”, “k2”) |
| 差集 |
sdiff(“k1”,“k2” ) |
template.opsForSet().difference(“k”, “k2”) |
| Zset |
|
|
| 增加 |
zadd(“k”,1,“a”) |
template.opsForZSet().add(“k”,“aa”,12) |
| 排名结果 |
zrevrange(“k”, 0, -1) |
template.opsForZSet().reverseRange(“k”, 0, -1) |
| 排名分数 |
zrevrangeByScoreWithScores(“k”, 12, 10); |
template.opsForZSet().reverseRangeByScore(“k”, 1, 100) |
| 修改分数 |
zincrby(“k”,20,“a”) |
template.opsForZSet().incrementScore(“k”,“aa”,19) |
| 数量 |
zcard(“k”) |
template.opsForZSet().zCard(“k”) |
| 获取排名 |
zrank(“k”,“a”) |
template.opsForZSet().rank(“k”,“aa”) |
