mapping from python to java and back

[ehudkaldor]

i am trying to generate clients for python and java in a way that python can serialize a model class (to Kafka) and loading it into Java Spring Boot application on the other end.

i have the python side generating pydantic-based models, which are great for serializtion, but on other end i cannot load them because the java generator generate model classes with camelCase field names, where the python side dumps them to json with snake_case field names.

my focus so far has been to try and get jackson to generate json mapping that would allow loading snake_case json into a model, but no success so far. i know pydantic supports serialization_alias which could be used to serialize to another name, but have had no success with this either.

anyone has any idea or experience with such a conversion?
