Description

I recently opened a bug in swagger-ui, but now I think its a problem with swagger codegen. This is the related post: https://github.com/swagger-api/swagger-ui/issues/2175

When I build Code out of a spec which has an Array the Code seems to be right, but when I run I can have max. 1 entry. It doesnt recognize a "," with the collectionFormat csv. It also doesnt work with a "|" when i choose pipe as collection Format. Here is the spec:

"parameters": [
  {
    "name": "api_key",
    "in": "header",
    "description": "description",
    "required": true,
    "type": "array",
    "items": {
      "type": "string"
    },
    "collectionFormat": "csv"
  }
]

Im build a JAX-RS -Jersey server and the swagger Codegen version is 2.1.6 and I run the Code with this:

-i swaggerPolicy.json \
  -l jaxrs \
  -o D:\Dateien\swagger_restacl_integration\SwaggerRestaclIntegration

Research direction
Investigate the JAX RS code generation templates in modules/swagger codegen/src/main/resources/JavaJaxRS/. Focus on how array header parameters with collectionFormat 'csv' are generated, ensuring the parameter type is List and the format is applied to parse comma separated values. Check for existing test coverage. No linked PR or maintainer comments, so propose a fix that handles collectionFormat correctly.
