In a very big Java app with lot's of DTOs, I want to export to an external project only the DTOs that are relevant to REST calls, and even better to export a part of them (the minimum required for REST calls).
The project uses Swagger and I am wondering if it is possible to take the output of Swagger (uses Java DTOs to create JSON\YAML files), which have the exact content I need, as an input to generate new Java DTO files. The generated files will be only those needed for REST and I will be able to easily export them.
Is this possible? If not, what is the best approach to do that?
Maybe check out swagger.generator.io where you can generate a whole client library (including DTO classes) for your specified swagger definition file. For documentation please refer to their github page. You can also do the generation of the API client locally utizing the swagger codegen tools.
