Spring + Springfox + Header Parameters

You could use the globalOperationParametersin the docket definition. For e.g.

new Docket(...)
            .globalOperationParameters(
        Arrays.asList(new ParameterBuilder()
            .name("header")
            .description("Description of header")
            .modelRef(new ModelRef("string"))
            .parameterType("header")
            .required(true)
            .build()))
