整合步骤

增加lombok插件

增加lombok依赖

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

实体类演示

@Data //生成getter  setter toString()等方法
@Slf4j  //生成日志对象
public class User2 {
    private String username;
    private Integer age;
    private Integer id;


    public static void main(String[] args) {
        User2 user2 = new User2();
        user2.setAge(12);
        Integer age = user2.getAge();
        user2.setUsername("kkk");
        String username = user2.getUsername();
        log.info("age:"+age+"username:"+username);
    }
}

结果
