MyBatis-lombok入门

作用：简化实体类的代码量

引入Lombok依赖

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
</dependency>

修改实体类的代码

import lombok.*;

//@Getter
//@Setter
//@ToString
//@EqualsAndHashCode
@Data//包括上面四个注解
@NoArgsConstructor//无参构造
@AllArgsConstructor//全参构造
public class User {
    private Integer id;
    private String name;
    private short age;
    private Short gender;
    private String address;
    }
