一、添加依赖（谨防依赖冲突）

                    <artifactId>mapstruct</artifactId>

            </exclusions>
        </dependency>

二、如果依赖下不下来，要在maven的setting文件中加入腾讯云的镜像

<mirror>
    <id>nexus-tencentyun</id>
    <mirrorOf>*</mirrorOf>
    <name>Nexus tencentyun</name>
    <url>http://mirrors.cloud.tencent.com/nexus/repository/maven-public/</url>
</mirror> 

三、 实战测试（将User转成UserDto）

import io.github.linpeilie.annotations.AutoMapper;
import lombok.Data;

@Data
// 只需在User类上加上注解即可
@AutoMapper(target = UserDto.class)
public class User {
    private String username;
    private int age;
    private boolean young;
}

import lombok.Data;

@Data
public class UserDto {
    private String username;
    private int age;
    private boolean young;
}

import com.ciih.penetration.test.User;
import com.ciih.penetration.test.UserDto;
import io.github.linpeilie.Converter;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
public class QuickStartTest {

    @Autowired
    private Converter converter;

    @Test
    public void test() {
        User user = new User();
        user.setUsername("jack");
        user.setAge(23);
        user.setYoung(false);

        UserDto userDto = converter.convert(user, UserDto.class);
        System.out.println(userDto);    // UserDto{username='jack', age=23, young=false}

        assert user.getUsername().equals(userDto.getUsername());
        assert user.getAge() == userDto.getAge();
        assert user.isYoung() == userDto.isYoung();

        User newUser = converter.convert(userDto, User.class);

        System.out.println(newUser);    // User{username='jack', age=23, young=false}

        assert user.getUsername().equals(newUser.getUsername());
        assert user.getAge() == newUser.getAge();
        assert user.isYoung() == newUser.isYoung();
    }

}
