无法使用Map结构映射嵌套的@Data

Question

当尝试使用@Data和@Builder映射嵌套对象时，mapStruct会抛出以下错误：“在目标类型中找不到属性“profile”的读取访问器。”

@Mapper(componentModel = "spring")
public interface AuthMapper {

  // only for testing mapping is working
  @Mapping(target = "profile.organization", source = "organization")
  RequestCreateOktaUser toEntity(Integer organization);

  // only for testing mapping is working
  @Mapping(target = "profile.login", source = "request.profile.email")
  RequestCreateOktaUser toEntity(RequestMobilePreRegisterLocation.User request);
  
  // Throw error "No read accessor found for property "profile" in target type" at compile time
  @Mapping(target = "profile.organization", source = "organization")
  @Mapping(target = "profile.login", source = "request.profile.email")
  RequestCreateOktaUser toEntity(RequestMobilePreRegisterLocation.User request, Integer organization);

}

为简单起见，使用Lombok简化模型

@Data
@NoArgsConstructor
@AllArgsConstructor(access = AccessLevel.PRIVATE)
@Builder
public class RequestCreateOktaUser {

  private Profile profile;

  @Data
  @NoArgsConstructor
  @AllArgsConstructor(access = AccessLevel.PRIVATE)
  @Builder
  public static class Profile {
    private String login;
    private String email;
    private Integer organization;
  }

}

@Data
@NoArgsConstructor
@AllArgsConstructor(access = AccessLevel.PRIVATE)
@Builder
public class RequestMobilePreRegisterUser {

  @Valid
  private User user;


  @Data
  @NoArgsConstructor
  @AllArgsConstructor(access = AccessLevel.PRIVATE)
  @Builder
  public static class User {

    @Valid
    private Profile profile;

    @Data
    @NoArgsConstructor
    @AllArgsConstructor(access = AccessLevel.PRIVATE)
    @Builder
    public static class Profile {

      @NotEmpty
      @Email
      private String email;

    }

}

前两个映射按预期工作，但当尝试将两者结合起来时，会在编译时引发以下错误“在目标类型中的属性“配置文件”中找不到读取访问器。”

如果有人能在这件事上帮我，我会非常感激。

谢谢，

解决方案：

@Mapper(componentModel = "spring", builder = @Builder(disableBuilder = true))
