I used `org.springframework.core.io.Resource` because that's what other parts of the spring generator are using already for files. see e.g. [here](https://github.com/OpenAPITools/openapi-generator/blob/1751163f366e2890f16aad369604dc77801acc4b/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/SpringCodegen.java#L550) I...

Hi, the changes look good to me. 👍 -------------- just some additional results from my experiments, in case this PR is referenced again in the future: - ```java String serialized...

It would be great if @wing328 or someone from the Java technical committee could take over reviewing this PR; both to add another perspective and because I currently can't work...

Thanks for the PR! It mostly looks good to me. But what is the intention behind `GenericTypeRef`?

For anyone who wants to work on this: This bug needs to be fixed [here](https://github.com/OpenAPITools/openapi-generator/blob/742c2c48e75340d9eedf1276874bce9958cfea46/modules/openapi-generator/src/main/resources/JavaSpring/pojo.mustache#L262C48-L263C29).
