                .version("1.0")
                .build();
    }

    //生成全局通用参数
    private List<RequestParameter> getGlobalRequestParameters() {
        List<RequestParameter> parameters = new ArrayList<>();
        parameters.add(new RequestParameterBuilder()
                .name("appid")
                .description("平台id")
                .required(true)
                .in(ParameterType.QUERY)
                .query(q -> q.model(m -> m.scalarModel(ScalarType.STRING)))

                .description("设备的唯一id")
                .required(true)
                .in(ParameterType.QUERY)
                .query(q -> q.model(m -> m.scalarModel(ScalarType.STRING)))
                .required(false)
                .build());
        parameters.add(new RequestParameterBuilder()
                .name("version")
                .description("客户端的版本号")
                .required(true)
                .in(ParameterType.QUERY)
                .query(q -> q.model(m -> m.scalarModel(ScalarType.STRING)))
                .required(false)
                .build());
         return parameters;
    }

    //生成通用响应信息
    private List<Response> getGlobalResonseMessage() {
        List<Response> responseList = new ArrayList<>();
        responseList.add(new ResponseBuilder().code("404").description("找不到资源").build());
         return responseList;
    }
}

依赖中ParameterType枚举类：

public enum ParameterType {
    QUERY("query"),
    HEADER("header"),
    PATH("path"),
    COOKIE("cookie"),
    FORM("form"),
    FORMDATA("formData"),
    BODY("body");

    private String in;

    private ParameterType(String in) {
        this.in = in;
    }

    public String getIn() {
        return this.in;
    }

    public static ParameterType from(String value) {
        return (ParameterType)Arrays.stream(values()).filter((each) -> {
            return Objects.equals(each.in, value);
        }).findFirst().orElse((Object)null);
    }
}

如果配置的是请求头将ParameterType.QUERY修改为：ParameterType.HEADER即可。
