Swagger Codegen use existing class

Question

How can I get the swagger codegen to use an existing class instead of creating a new class? Is this possible? For instance I want to use org.springframework.data.domain.Pa

It's not always possible to use --import-mappings if you have long list of mappings. (At least in case of Windows, which has size-limit for string in command prompt.) That is why better way do it: use mapping with swagger configuration file. (And this option is not fully documented.)

Like that:

java -jar swagger-codegen-cli-2.3.1.jar generate -i myspec.yaml -l java -c myconfig.json

myconfig.json:

{
  "hideGenerationTimestamp": true,
  "dateLibrary": "java8",
  "useRuntimeException": true,
  "modelPackage": "org.my.package.model",
  "apiPackage": "org.my.package.api",
  "importMappings": {
    "Page": "org.springframework.data.domain.Page",
    "MySuperType": "org.my.SuperType"
  }
}
