a simple OpenAPI interface only code generator for Spring Boot.

See the documentation.

See openapi-generatr-spring-mvc-sample for a complete working sample of a minimal openapi.yaml.

In case some feature is missing or the generated code is not 100% what you would expect create an issue with test case. Providing a test case will help significantly :-)

A test case is a single folder with an openapi.yaml file and the expected Java files the generatr should create. The structure looks like this:

my-new-test-case/ openapi.yaml mapping.yaml generated/ api/ AnEndpointInterface.java .. more api interfaces .. model/ AModelClass.java AnotherModelClass.java .. more model files .. 

The mapping.yaml contains the type mapping information and is an optional file.

See the existing integration tests for a couple of examples.
