Deep understanding of the use of spring Redis (vii), Spring Redis using Jackson serialization, and Basedao code

Before introducing spring Redis for storage, it was through the Defaultserializer in Redistemplate, the Jdkserializationredisserializer. The serialization of the JDK is relatively straightforward, but sometimes it can be viewed through the console at the time of online debugging, completely invisible. And in space occupancy and performance, compared to Jackson, there is absolutely no advantage.

There have been two times the problem on the line, the location of the time to know that the cache is wrong, but do not know exactly in that cache field, debugging is very inconvenient. So the serialization was replaced by Jackson.

The code is as follows:

For the serialization of key, directly in the configuration file definition

<BeanID= "Redistemplate"class= "Org.springframework.data.redis.core.RedisTemplate"Scope= "Prototype">        < Propertyname= "ConnectionFactory"ref= "Jedisconnectionfactory" />        < Propertyname= "Keyserializer"ref= "Stringkeyserializer"/>        < Propertyname= "Enabletransactionsupport"value= "true"/><!--Configure true to use transactional to control transactions, spring has provided support -    </Bean>
