一、添加依赖（谨防依赖冲突）

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

三、 实战测试（将User转成UserDto）

#### 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();
        }
    
    }
