1.0 StringRedisTemplate与RedisTemplate

spring 封装了 RedisTemplate 对象来进行对redis的各种操作，它支持所有的 redis 原生的 api。在RedisTemplate中提供了几个常用的接口方法的使用，分别是:

private ValueOperations<K, V> valueOps;
private HashOperations<K, V> hashOps;
private ListOperations<K, V> listOps;
private SetOperations<K, V> setOps;
private ZSetOperations<K, V> zSetOps;

RedisTemplate中定义了对5种数据结构操作

redisTemplate.opsForValue();//操作字符串
redisTemplate.opsForHash();//操作hash
redisTemplate.opsForList();//操作list
redisTemplate.opsForSet();//操作set
redisTemplate.opsForZSet();//操作有序set

​

StringRedisTemplate继承自RedisTemplate，也一样拥有上面这些操作。

StringRedisTemplate默认采用的是String的序列化策略，保存的key和value都是采用此策略序列化保存的。

RedisTemplate默认采用的是JDK的序列化策略，保存的key和value都是采用此策略序列化保存的。

2.0 RedisTemplate中的方法列表

String类型结构
Redis	RedisTemplate rt
set key value	rt.opsForValue().set("key","value")
get key	rt.opsForValue().get("key")
del key	rt.delete("key")
strlen key	rt.opsForValue().size("key")
getset key value	rt.opsForValue().getAndSet("key","value")
getrange key start end	rt.opsForValue().get("key",start,end)
append key value	rt.opsForValue().append("key","value")
Hash结构
hmset key field1 value1 field2 value2...	rt.opsForHash().putAll("key",map) //map是一个集合对象
hset key field value	rt.opsForHash().put("key","field","value")
hexists key field	rt.opsForHash().hasKey("key","field")
hgetall key	rt.opsForHash().entries("key") //返回Map对象
hvals key	rt.opsForHash().values("key") //返回List对象
hkeys key	rt.opsForHash().keys("key") //返回List对象
hmget key field1 field2...	rt.opsForHash().multiGet("key",keyList)
hsetnx key field value	rt.opsForHash().putIfAbsent("key","field","value"
hdel key field1 field2	rt.opsForHash().delete("key","field1","field2")
hget key field	rt.opsForHash().get("key","field")
List结构
lpush list node1 node2 node3...	rt.opsForList().leftPush("list","node")
rt.opsForList().leftPushAll("list",list) //list是集合对象
rpush list node1 node2 node3...	rt.opsForList().rightPush("list","node")
rt.opsForList().rightPushAll("list",list) //list是集合对象
lindex key index	rt.opsForList().index("list", index)
llen key	rt.opsForList().size("key")
lpop key	rt.opsForList().leftPop("key")
rpop key	rt.opsForList().rightPop("key")
lpushx list node	rt.opsForList().leftPushIfPresent("list","node")
rpushx list node	rt.opsForList().rightPushIfPresent("list","node")
lrange list start end	rt.opsForList().range("list",start,end)
lrem list count value	rt.opsForList().remove("list",count,"value")
lset key index value	rt.opsForList().set("list",index,"value")
Set结构
sadd key member1 member2...	rt.boundSetOps("key").add("member1","member2",...)
rt.opsForSet().add("key", set) //set是一个集合对象
scard key	rt.opsForSet().size("key")
sidff key1 key2	rt.opsForSet().difference("key1","key2") //返回一个集合对象
sinter key1 key2	rt.opsForSet().intersect("key1","key2")//同上
sunion key1 key2	rt.opsForSet().union("key1","key2")//同上
sdiffstore des key1 key2	rt.opsForSet().differenceAndStore("key1","key2","des")
sinter des key1 key2	rt.opsForSet().intersectAndStore("key1","key2","des")
sunionstore des key1 key2	rt.opsForSet().unionAndStore("key1","key2","des")
sismember key member	rt.opsForSet().isMember("key","member")
smembers key	rt.opsForSet().members("key")
spop key	rt.opsForSet().pop("key")
srandmember key count	rt.opsForSet().randomMember("key",count)
srem key member1 member2...	rt.opsForSet().remove("key","member1","member2",...)
