创建 DTO、VO
StudentDto
package com.ams.springbootmapstruct.dto;
import lombok.Data;
/**
* Created with IntelliJ IDEA.
*
* @author： AI码师
* @date： 2021/11/27
* @description：
* @modifiedBy：
* @version: 1.0
*/
@Data
public class StudentDto {
private String userName;
private String userId;
private String address;
private String school;
private int age;
private String email;
}
StudenVo
package com.ams.springbootmapstruct.vo;
import lombok.Builder;
import lombok.Data;
/**
* Created with IntelliJ IDEA.
*
* @author： AI码师
* @date： 2021/11/27
* @description：
* @modifiedBy：
* @version: 1.0
*/
@Data
@Builder
public class StudentVo {
private String userName;
private String userId;
private String address;
private String school;
private int age;
private String emailAddress;
}
创建mapstruct转换器
package com.ams.springbootmapstruct.mapper;
import com.ams.springbootmapstruct.dto.StudentDto;
import com.ams.springbootmapstruct.vo.StudentVo;
import org.mapstruct.Mapper;
@Mapper(componentModel = "spring")
public interface MainMapper {
StudentDto studentVo2Dto(StudentVo vo);
}
编写测试用例
package com.ams.springbootmapstruct;
import com.ams.springbootmapstruct.dto.StudentDto;
import com.ams.springbootmapstruct.mapper.MainMapper;
import com.ams.springbootmapstruct.vo.StudentVo;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class SpringbootMapstructApplicationTests {
@Autowired
private MainMapper mainMapper;
@Test
void testSimpleMap() {
StudentVo studentVo = StudentVo.builder()
.school("清华大学")
.userId("ams")
.userName("AI码师")
.age(27)
.address("合肥")
.build();
StudentDto studentDto = mainMapper.studentVo2Dto(studentVo);
System.out.println(studentDto);
}
}
mapstruct常规操作
不同字段映射
package com.ams.springbootmapstruct.mapper;
import com.ams.springbootmapstruct.dto.StudentDto;
import com.ams.springbootmapstruct.vo.StudentVo;
import org.mapstruct.Mapper;
import org.mapstruct.Mapping;
@Mapper(componentModel = "spring")
public interface MainMapper {
@Mapping(source = "emailAddress", target = "email")
StudentDto studentVo2Dto(StudentVo vo);
}
LIST转换
package com.ams.springbootmapstruct.mapper;
import com.ams.springbootmapstruct.dto.StudentDto;
import com.ams.springbootmapstruct.vo.StudentVo;
import org.mapstruct.Mapper;
import org.mapstruct.Mapping;
import java.util.List;
@Mapper(componentModel = "spring")
public interface MainMapper {
@Mapping(source = "emailAddress", target = "email")
StudentDto studentVo2Dto(StudentVo vo);
List<StudentDto> studentListVo2Dto(List<StudentVo> vo);
}
