使用mapstruct从单个元素映射嵌入式列表

Question

我和mappstruct一起工作，我有一个问题，我不知道mapstruct是否能帮上忙。问题是我有一个DATA类。

public class Data {
    private String firstName;
    private String lastName;
    private String state;
    private String city;
    private String street;
    private String zipCode;
}

和地址

Entity
public class Address {
    @Id
    private Long id;
    private String state;
    private String city;
    private String street;
    private String zipCode;

和“人”

@Data
public class Person {
    @Id
    private Long id;
    private String firstName;
    private String lastName;
    private String email;
    private List<Address> list;
}```

So the person have a list of address and I want from One Data object create one adresse Object 
and add that object to Person  
So after the mapping I need to have Person with List(size == 1) of address 

the mapper 

@Mapper公共接口DataToPerson {

DataToPerson MAPPER = Mappers.getMapper(DataToPerson.class);

Person dataToPerson(Data data);

}

 is that possible ? 

Thank you so much

为了执行这样的映射，您需要告诉MapStruct如何映射到< code >列表中

e. g.

@Mapper
public interface DataToPerson {

    DataToPerson MAPPER = Mappers.getMapper(DataToPerson.class);

    @Mapping(target = "list", source = "data")
    Person dataToPerson(Data data);

    default List<Address> dataToAddressList(Data data) {
        return data != null ? Collections.singletonList(dataToAddress(data)) : null;
    }

    Address dataToAddress(Data data);

}
