mybatis lombok Ошибка создания класса

Я пытаюсь использовать mybatis для подключения локального mysql databse и lombok для объекта POJO, но я получил ошибку «Ошибка создания экземпляра класса». Я искал некоторые результаты, похоже, мне нужно создать конструктор для POJO, но я думаю, что мне нужно это делать, если я использую ломбок?mybatis lombok Ошибка создания класса

Admin.java

пакет com.cooldrinker.mybatis.model;

импорт lombok.Builder; импорт lombok.Data;

@Builder 
@Data 
public class Admin { 
    private String firstName; 
    private String lastName; 
    private String password; 
    private String userName; 
}

Из документации Ломбок (https://projectlombok.org/features/Builder.html):

«Наконец, применяя @Builder к классу, как если бы вы добавили @AllArgsConstructor (доступ = AccessLevel.PACKAGE) к классу и применил аннотацию @Builder к этому конструктору all-args. Это работает только в том случае, если вы не написали никаких явных конструкторов самостоятельно. Если у вас есть явный конструктор, поместите аннотацию @Builder в конструктор вместо по классу ".

Итак, чтобы MyBatis использовал конструктор non argument, вы должны добавить его в класс. С другой стороны, ваш resultMap может использовать тег <constructor>, чтобы использовать сгенерированный конструктор.

Не прочитав документацию, я думаю, вам может понадобиться конструктор no-args. У вас есть только конструктор all-args. Вы можете сказать Ломбоку, чтобы сгенерировать их, добавив @NoArgsConstructor и @AllArgsConstructor к типу.
