/**

@JsonFormat(shape = JsonFormat.Shape.OBJECT)
public enum UserLevel {


    /**
     * 未注册
     * */
    TOURIST("1","游客"),


    /**
     * 已注册
     * */
    REGISTER("2","已注册"),


    String code;
    String desc;


    UserLevel(String code, String desc) {
        this.code = code;
        this.desc = desc;
    }


    public String getCode() {
        return code;
    }


    public String getDesc() {
        return desc;
    }


    public static UserLevel getUserLevel(String code) {
        for (UserLevel l : UserLevel.values()) {
            if (l.getCode().equals(code))  {
                return l;
            }
        }
        return null;
    }


}

controller直接return

return UserLevel.getUserLevel(code);

返回json

{

        "code": "1",

        "desc": "游客"

}
