如何将多个字段映射/合并到一个字段中？就像将.validate和firstname连接到目标lastname？
fullname答案 0 :(得分：3)
您可以在public class ModelMapperConfigTest {
@Test
public void should_validate() {
new ModelMapperConfig().modelMapper().validate();
}
@Data
public static class Person {
private String firstname;
private String lastname;
}
@Data
public static class PersonDto {
private String firstname;
private String lastname;
private String fullname;
}
// Test data
@Test
public void should_map_multiple_fields_into_one() {
ModelMapper modelMapper = new ModelMapper();
modelMapper.getConfiguration().setMatchingStrategy(MatchingStrategies.STRICT);
// TODO: Configure modelmapper to merge the two fields
// test that all fields are mapped
modelMapper.validate();
// test that the age is calculated
Person person = new Person();
person.setFirstname("Marilyn");
person.setLastname("Monroe");
PersonDto personDto = modelMapper.map(person, PersonDto.class);
assertEquals(personDto.fullname, "Marilyn Monroe");
}
// This method should be used for mapping. In real, this could be a service call
private String generateFullname(String firstname, String lastname) {
return firstname + " " + lastname;
}
}
内使用Converter。
只需像这样配置你的映射器：
PropertyMap
