[JAVA] Question : How can I generate constructors for model classes?

Description

All ,

I am new to swagger and I'd like to add constructors to my generated models. How can I do that?

In the current examples , the generated models provide setters and getters , but my goal is to generate public constructors along with them.

Swagger-codegen version

Version 2.0

Swagger declaration file content or url

I am using Swagger Petstore (Simple)

Command line used for generation

I am using Swagger editor 2 --> Generate Server --> Jaxrs-resteasy

Steps to reproduce

1. Visit Swagger editor 2
   
2. Click in File -> Open Example -> And select petstore_simple.yaml
3. Click in Generate Server --> Jaxrs-resteasy
4. From the generated code , open src\gen\java\io\swagger\model\Pet.java

Expected : There is a constructor for the Pet class

Actual : There are no constructors and only setters and getters.

Edit : Reading this I stumbled up the idea that it can generate code for the builder pattern. Could someone please explain how to set this up?

Start by reproducing the Swagger Petstore Simple example in Swagger Editor 2 with Generate Server → Jaxrs-resteasy, then inspect src\gen\java\io\swagger\model\Pet.java and the generation templates or configuration used for Java models. Determine how model constructors or builder-style generation is represented, and confirm done when generated models include the requested public constructors without losing the existing getters and setters.
