如何在Userdao中使用地址变量映射Userdao中的地址变量

Question

我有4个Java类，如下所述。手动创建bean映射器非常耗时。该库可以自动生成bean映射器类。

public class UserDao {

    private int id;
    private String name;
    private List<AddressDao> address;
}


public class AddressDao {

    public String city;
    public String Country;
}

public class UserDto {

    private int userID;
    private String userName;
    private List<AddressDto> userAddress;
}

public class AddressDto {

    private String userCity;
    private String userCountry;
}

如何将用户地址变量与UserD映射到地址变量。

@Mappings({
        @Mapping(source ="id" ,target="userID"),

        @Mapping(source ="name" ,target="userName"),

        @Mapping(source ="userdao.address.city" ,target="userAddress.userCity"),

        @Mapping(source ="userdao.address.country" ,target="userAddress.userCountry")

    })

    public UserDto usertouserDto(UserDao userdao);

    public List<UserDto> usertoUserDtos(List<UserDao> userDao);

这种方式不起作用。

@@ Mapper（componentModel =“ spring”，使用= {AddressMapper.class}）公用接口UserdtoMapper {

    @Mapping(source ="id" ,target="userID")
    @Mapping(source ="name" ,target="userName")
    UserDto usertouserDto(UserDao userdao);

    List<UserDto> usertoUserDtos(List<UserDao> userDao);     

}

@@ Mapper（componentModel =“ spring”）公用接口AddressMapper {

@Mappings({
    @Mapping(source ="city" ,target="userCity"),
    @Mapping(source ="Country" ,target="userCountry")
})

AddressDto mappingAddressDto(AddressDao addressDao);

List<AddressDto> mappingAddressDto(List<AddressDao> addressDao);

}

使用解决了我的问题。
