Spring boot can not read data from redis cache serializer.SerializationException: Cannot deserialize

I am trying to made spring boot app that is reading data from redis cache. But I can not.

Firstly I am calling post api to create user and then I am calling get api to getUserById but I am getting error like this:

java.lang.ClassNotFoundException:com.umut.redis.redisExample.Model.UserEntity atjava.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:581)~[na:na] atjava.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178)~[na:na] atjava.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521)~[na:na] at java.base/java.lang.Class.forName0(Native Method)~[na:na] at java.base/java.lang.Class.forName(Class.java:398)~[na:na] atorg.springframework.boot.devtools.restart.classloader.RestartClassLoader.loadClass(RestartClassLoader.java:145)~[spring-boot-devtools-2.5.6.jar:2.5.6] atjava.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521)~[na:na] at java.base/java.lang.Class.forName0(Native Method)~[na:na]

I am running docker container to redis.
