Spring defines the following implementation of cacheManger. JdkSerializationRedisSerializer: Use the serialization capabilities provided by JDK.The advantage is that you do not need to provide type information when deserializing, but the disadvantage is that you need to implement the Serializable interface, and the serialized result is very large, about five times the JSON format, which consumes a lot of memory on the redis server.
