redis的hash表使用

======Hest设置map名称还有一个key和value
127.0.0.1:6379> HSET hashMapName key1 Value1
(integer) 1
127.0.0.1:6379> HSET hashMapName key2 Value2
(integer) 1

==========我们会看到多了我们设置的hashMap的key
127.0.0.1:6379> keys *

1. “hashMapName”

======hget获取一个
127.0.0.1:6379> HGET hashMapName key1
“Value1”

=========也可以用hgetall获取查看所有的
127.0.0.1:6379> HGETALL hashMapName

1. “key1”
2. “Value1”
3. “key2”
4. “Value2”
