将一个DTO的参数分配给另一个DTO

public class SourceDTO {
    private String name;
    private int age;
    private String email;

    // Getters and Setters
}

public class TargetDTO {
    private String fullName;
    private int userAge;
    private String contactEmail;

    // Getters and Setters
}

public class DTOConverter {
    public static TargetDTO convert(SourceDTO source) {
        TargetDTO target = new TargetDTO();
        target.setFullName(source.getName());
        target.setUserAge(source.getAge());
        target.setContactEmail(source.getEmail());
        return target;
    }
}

// 使用示例
public class Main {
    public static void main(String[] args) {
        SourceDTO source = new SourceDTO();
        source.setName("John Doe");
        source.setAge(30);
        source.setEmail("john.doe@example.com");

        TargetDTO target = DTOConverter.convert(source);
        System.out.println("Full Name: " + target.getFullName());
        System.out.println("Age: " + target.getUserAge());
        System.out.println("Email: " + target.getContactEmail());
    }
}

@Mapper
public interface DTOMapper {
    DTOMapper INSTANCE = Mappers.getMapper(DTOMapper.class);

    @Mapping(source = "name", target = "fullName")
    @Mapping(source = "age", target = "userAge")
    @Mapping(source = "email", target = "contactEmail")
    TargetDTO sourceToTarget(SourceDTO source);
}

@Mapper
public interface NestedDTOMapper {
    NestedDTOMapper INSTANCE = Mappers.getMapper(NestedDTOMapper.class);

    @Mapping(source = "nestedSource.name", target = "nestedTarget.fullName")
    NestedTargetDTO nestedSourceToNestedTarget(NestedSourceDTO nestedSource);
}
