Description

Date parameters in the path should be serialized according to RFC3339 (YYYY-MM-DD) but are actually serialized as M/D/YY. This was already addressed in the queryParams template by specifying a DateTimeFormat. The same logic should be used in the pathParams template.

openapi-generator version

Using OpenAPI Generator 5.3.0

OpenAPI declaration file content or url
components:
  parameters:
    MyDateParam:
      name: myDate
      in: path
      required: true
      type: string
      format: date
Generation Details

Using the following settings:

  • module: JavaSpring
  • library: spring-cloud
  • dateLibrary: java8
Steps to reproduce

Serialize a pathParam date using a Feign client. The resulting path will contain an incorrect date.

Suggest a fix

The same issue was already addressed in the queryParams template. Applying it to the pathParams template resolves the issue. I'll submit a PR shortly.
