Description

When adding examples of usages of parameters, the code is not copied to the interface of the delegate.

openapi-generator version

Version: 6.2.1

OpenAPI declaration file content or url

    Size:
      in: query
      name: size
      required: false
      schema:
        type: integer
      description: size of the page
    Page:
      in: query
      name: page
      required: false
      schema:
        type: integer
      description: page number

      schema:
        type: array
        items:
          type: string
      description: sort by field and direction (asc or desc)
      examples:
        simple-default-order:
          value: [ companyName ]
          summary: Sort by companyName in ascending order
        simple:
          value: [ companyName,desc ]
          summary: Sort by companyName in descending order
        multiple:
          value: [ companyName,asc,companyStatus,desc ]
          summary: Sort by companyName in ascending order and companyStatus in descending order
        wrong:
          value: [ companyName,companyStatus,asc,desc ]
          summary: WRONG - Sort by fields and then all directions

Generation Details

The output has nothing related to the examples

    default ResponseEntity<FooEntityDto> getAllFooEntity(
        @Parameter(name = "size", description = "size of the page") @Valid @RequestParam(value = "size", required = false) Integer size,
        @Parameter(name = "page", description = "page number") @Valid @RequestParam(value = "page", required = false) Integer page,
        @Parameter(name = "sort",  description = "sort by field and direction (asc or desc)" @Valid @RequestParam(value = "sort", required = false) List<String> sort
    ) {
        return getDelegate().getAllCompanyRegistrations(size, page, sort);
    }

Expected something like this to be generated.

    default ResponseEntity<FooEntityDto> getAllFooEntity(
        @Parameter(name = "size", description = "size of the page") @Valid @RequestParam(value = "size", required = false) Integer size,
        @Parameter(name = "page", description = "page number") @Valid @RequestParam(value = "page", required = false) Integer page,
        @Parameter(name = "sort",
                description = "sort by field and direction (asc or desc)",
        examples = {
                @ExampleObject(name="simple-default-order", summary = "Sort by companyName in ascending order", value = "[companyName]"),
                @ExampleObject(name="simple", summary = "Sort by companyName in descending order", value = "[companyName,desc]"),
                @ExampleObject(name="multiple", summary = "Sort by companyName in ascending order and companyStatus in descending order",
                        value = "[companyName,asc,companyStatus,desc]"),
                @ExampleObject(name="wrong", summary = "WRONG - Sort by fields and then all directions",
                        value = "[companyName,companyStatus,asc,desc]")
        })
        @Valid @RequestParam(value = "sort", required = false) List<String> sort
    ) {
        return getDelegate().getAllCompanyRegistrations(size, page, sort);
    }

To match the output of the original openApi UI output form the definition:

And not something like this, based on the JAVA code generated:

Steps to reproduce

Create a component parameter, that contain an example or examples, and review the definition of Api interface to see if the code there has none of elements example or examples defined in the Swagger file.

Reproduce the issue with the provided OpenAPI parameter declaration and inspect Java delegate-interface generation, starting with how parameter examples are handled. Done means the generated delegate interface includes the parameter examples as annotation metadata, matching the expected Java output, with regression coverage for the supplied case.
