Use Serializer from EclipseStore with TypeHandlers

[tschuehly]

I want to use the Eclipse Serializer for the Spring Modulith Event Registry, as the default Jackson Serialization doesn't work with my generic Event Structure.: https://docs.spring.io/spring-modulith/reference/events.html#publication-registry.serialization

I have tried using the TypedSerializer but then when restarting the application it has an ID mismatch.
We are already using EclipseStore.
Is it possible to use the Serializer with the TypeDictonary that is saved by EclipseStore?

I have created an example: https://github.com/tschuehly/modulith-eclipse-serializer

There is an option to initialize the serializer with a predefined TypeDictionary by providing a custom PersistenceTypeDictionaryLoader that provides the TypeDictionary as a String.

String typeDictionaryString = ...
final SerializerFoundation<?> foundation = SerializerFoundation.New();
foundation.setTypeDictionaryLoader(()->typeDictionaryString);

The typeDictionaryString can be exported from another Serializer instance:

final String typeDictionaryString = foundation.getTypeDictionaryAssembler()
    .assemble(foundation.getTypeDictionaryManager().provideTypeDictionary());

Of course, you can initialize that String also from an existing type-dictionary file.

Thanks for the answer!

I edited the example howto export the type dictionary from a serializer. The wrongly posted API is not jet available.
