Frequently Asked Questions

What Java features are supported?

The generator creates Java classes with proper constructors, getters/setters, and supports Jackson annotations for JSON serialization, Lombok for boilerplate reduction, and standard Java conventions.

Can I generate Lombok-compatible classes?

Yes! Select 'Lombok' as the framework to generate classes with @Data, @AllArgsConstructor, and @NoArgsConstructor annotations, eliminating boilerplate code.

How does Jackson integration work?

When Jackson framework is selected, the generator adds @JsonProperty annotations to fields for proper JSON serialization/deserialization with custom property names.

What about package structure?

You can specify custom package names in the options. The generator will add the appropriate package declaration at the top of the generated Java file.
