Description

According to the docs for the jaxrs-spec generator it should support the x-field-extra-annotation extension on the OPERATION_PARAMETER level. This is false.

The generated code looks something like this:

@Path("/asset")
@jakarta.annotation.Generated(value = "org.openapitools.codegen.languages.JavaJAXRSSpecServerCodegen", comments = "Generator version: 7.19.0")
public interface AssetApi {
    @GET
    @Path("/{id}")
    @Produces({ "application/json" })
    Response getAsset(@PathParam("id") UUID id,@HeaderParam("X-Locale")   String xLocale);
}

It should look like this instead.

@Path("/asset")
@jakarta.annotation.Generated(value = "org.openapitools.codegen.languages.JavaJAXRSSpecServerCodegen", comments = "Generator version: 7.19.0")
public interface AssetApi {
    @GET
    @Path("/{id}")
    @Produces({ "application/json" })
    Response getAsset(@PathParam("id") @org.hibernate.validator.constraints.UUID(version = {7}) @jakarta.validation.constraints.NotNull UUID id);
}

Generation Details

I use maven 3.9.11 and java 21 to generate my server files. The configuration is completely in the maven plugin under <configOptions>. For readability, these are the parameters I configured that affect the code generation:

generatorName: jaxrs-spec
configOptions:
    library: quarkus
    sourceFolder: src/gen/java/main
    apiPackage: com.test
    dateLibrary: java8
    modelPackage: com.test.model
    returnResponse: true
	

Steps to reproduce

• generate the code
• look into the generated AssetApi.java file and see that the annotations that should be on the getAsset method are missing.

The template for the jaxrs-spec generator looks like this:
JavaJaxRS/spec/queryParams.mustache

{{#isPathParam}}@PathParam("{{baseName}}"){{#useBeanValidation}}{{>beanValidationPathParams}}{{/useBeanValidation}}{{#useSwaggerAnnotations}}{{#description}} @ApiParam("{{.}}"){{/description}}{{/useSwaggerAnnotations}}{{#useMicroProfileOpenAPIAnnotations}}{{#description}} @org.eclipse.microprofile.openapi.annotations.parameters.Parameter(description="{{.}}"){{/description}}{{/useMicroProfileOpenAPIAnnotations}} {{{dataType}}} {{paramName}}{{/isPathParam}}

In comparison the template for spring looks like this:
JavaSpring/queryParams.mustache

{{#isPathParam}}{{#vendorExtensions.x-field-extra-annotation}}{{{.}}} {{/vendorExtensions.x-field-extra-annotation}}{{#useBeanValidation}}{{>beanValidationPathParams}}{{/useBeanValidation}}{{>paramDoc}} @PathVariable("{{baseName}}"){{>dateTimeParam}}{{#isDeprecated}} @Deprecated{{/isDeprecated}} {{>optionalDataType}} {{paramName}}{{/isPathParam}}

The jaxrs-spec template seems to be missing the {{#vendorExtensions.x-field-extra-annotation}} templating parameter.

Start with modules/openapi-generator/src/main/resources/JavaJaxRS/spec/pathParams.mustache and compare it with the referenced JavaSpring/pathParams.mustache template. Run the supplied OpenAPI declaration through the jaxrs-spec generator, then verify that the generated AssetApi.java includes both x-field-extra-annotation values on the path parameter.
