假设我有这些实体：

public class Address {
    private String id;
    private String address;
    private City city;
}

public class City {
    private int id;
    private Department department;
    private String zipCode;
    private String name;
    private Double lat;
    private Double lng;
}

public class Department {
    private int id;
    private Region region;
    private String code;
    private String name;
}

public class Region {
    private int id;
    private String code;
    private String name;
}

这个dto：

public class AddressDTO {
    private String address;
    private String department;
    private String region;
    private String zipCode;
}

在我的dto中，我想Map
离市部门/部门/姓名
来自城市/部门/地区/名称的地区
这是我的Map：

@Mapper(componentModel = "spring")
public interface AddressMapper {
    AddressDTO addressToAddressDTO(Address item);
}
