| Redis commands | Jedis corresponding API |
| set key value | String set(String key, String value) |
| get key | String get(String key) |
| exists key | Long exists(String... keys) |
| del key | Long del(String key) |
| type key | String type(String key) |
| incr key | Long incr(String key) |
| incrby key increment | Long incrBy(String key, long increment) |
| incrbyfloat key incrment | Double incrByFloat(String key, double increment) |

| strlen key | Long strlen(String key) |
| mset key1 value1 key2 value2 | String mset(k1, v1, k2, v2...) |
| mget key1 key2... | List<String> mget(k1, k2) |
Type hash (hash)
| Redis commands | Features | Jedis corresponding API |
| hset key field value | Create a key, for the value field assignment | |
| hsetnx key field value | When the key is not present in the field is that it is created, and assigned value; otherwise, do nothing | |
| hmset key field1 value1 field2 value2 | Create key, assigned to field1 value1, value2 assigned to field | |
| hget key field | Get key value in the field of | |
| hmget key field1 field2 | Obtain key in field1, field2 of value | |
| hgetall key | Get all of the key fields | |
| hexists key field | Field determines whether there is filed in the key | There is return 1, otherwise it returns 0 |
| hincrby key field increment | Increase in the key field | |
| hdel key field | Delete key fields in the field | |
| hkeys key | All field lists the key | |
| whales key | Lists all the key value | |
| hlen key | Get the number of key fields in |
List type (list)
| command | Features | Precautions |
| lpush key value1 value2 | Adding one or more elements to the left end of the list | |
| rpush key value1 value2 | Adding one or more elements to the right of the list | |
| lpop key | Pops an element from the left of the list | Will remove elements |
| rpop key | Pops an element from the right side of the list | Will remove elements |
| len | Gets the number of elements in the list | |
| lrange key start end | From left to right start to get the element end | It contains elements both ends |
| rrange key start end | This is not a command | |
| lrange key 0 -1 | Get all elements in the list | |
| lindex key index | Gets the value of the first index key elements | list as array |
| lset key index value | Set the key value for the index value of the index element | |
| ltrim key start end | Delete all the key elements start to end outside the | Reservations start and end |
| linsert key before/after oneValue value | In the key value of brfore oneValue element value or after adding a value |
从左到右查找到第一个 |
| rpoplpush | 将一个列表中的元素全部转移到另一个列表 |
|
| lrem key count value | 删除key中count个值为value的元素 | count>0时，从左到右，删除前count个值为value的元素； count<0时，从右到左，删除前|count|个值为value的元素； count=0时，删除所有等于value的元素 |
无序集合类型（set）
| 命令 | 功能 | 注意事项 |

| sunion key1 key2... | 并集（属于A，或属于B） | |
| scard key | 返回集合key中元素的个数 | |
| srandmember key [count] | 从集合key中随机获取|count|个元素，省略count表示获取一个 | count>0,获得的值不重复； count<0,获得的值可能相同； |
| spop | 从集合key中随机弹出一个元素，同时删除该元素 |
