模型映射器:匹配多个源属性层次结构
2022-09-01 16:40:21
我无法解决模型映射器错误。你有什么想法,问题出在哪里吗?
注意:鉴于java.sql.Time没有非参数构造函数,我没有找到比编写转换器更好的方法
org.modelmapper.ConfigurationException: ModelMapper configuration errors:
1) The destination property
biz.models.CarWash.setSecondShift()/java.util.Date.setTime() matches
multiple source property hierarchies:
biz.dto.CarWashDTO.getFirstShift()/java.time.LocalTime.getSecond()
biz.dto.CarWashDTO.getSecondShift()/java.time.LocalTime.getSecond()
此代码导致错误
@SpringBootTest
@RunWith(SpringRunner.class)
public class CarWashDTO2CarWash {
@Autowired
protected ModelMapper modelMapper;
@Test
public void testCarWashDTO2CarWash_allFiledShouldBeConverted(){
CarWashDTO dto = CarWashDTO.builder()
.name("SomeName")
.address("SomeAddress")
.boxCount(2)
.firstShift(LocalTime.of(9, 0))
.secondShift(LocalTime.of(20, 0))
.phoneNumber("5700876")
.build();
modelMapper.addConverter((Converter<CarWashDTO, CarWash>) mappingContext -> {
CarWashDTO source = mappingContext.getSource();
CarWash destination = mappingContext.getDestination();
destination.setId(source.getId());
destination.setFirstShift(source.getFirstShift() == null ? null : Time.valueOf(source.getFirstShift()));
destination.setSecondShift(source.getSecondShift() == null ? null : Time.valueOf(source.getSecondShift()));
destination.setEnable(true);
destination.setAddress(source.getAddress());
destination.setBoxCount(source.getBoxCount());
destination.setName(source.getName());
destination.setDateOfCreation(source.getDateOfCreation());
return destination;
});
final CarWash entity = modelMapper.map(dto, CarWash.class);
assertNotNull(entity);
assertEquals(2, entity.getBoxCount().intValue());
assertEquals("SomeAddress", entity.getAddress());
assertEquals("SomeName", entity.getName());
}
}
模型映射器 Bean 由下一个配置构建
@Bean
public ModelMapper modelMapper(){
return new ModelMapper();
}
数字:
public class CarWashDTO {
private Long id;
private String name;
private String address;
private String phoneNumber;
private Integer boxCount;
private LocalTime firstShift;
private LocalTime secondShift;
private LocalDateTime dateOfCreation;
}
Entity(firstShift 和 secondShift 有 java.sql.Time type):
public class CarWash {
private Long id;
private String name;
private String address;
private String phoneNumber;
private Integer boxCount;
private Time firstShift;
private Time secondShift;
private LocalDateTime dateOfCreation;
private Boolean enable;
private Owner owner;
}
