When Redis reads an integer of a string type, it is treated as an integer directly

An interesting question today is that when the system loads a string type of shaping data from MySQL into Redis and then takes it out of Redis, its type becomes an integer type, and the procedure is as follows:

The key in the database is a varchar-type number, such as a date type that 4,value is a varchar type, such as 2014-12-19

It is then loaded into Redis and then removed from Redis and placed in map<string,string>, but through a string type key, such as "4", it is not possible to extract the date string from map for 2014-12-19, The result of a look at the map of key (4) type, incredibly is an integer type, can only be integer.parse after the get, sure enough to take out, really pit Ah, hereby notes!
