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);
    }
}
