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. The use of spring data for Redis guarantees a solution which does not utilize any redis command in the code. When updating the object, the updated content needs to be stored in the database. Whether it is a hibernate object, or a user session or a plain old java object, RedisInsight reverse-engineers and show it to you nicely. * Since Java serialization is (at least, for now) included in Java, it’s still commonly used, including by Spring Session JDBC.
