无法使用 MapStruct 映射嵌套的 @Data答案

【问题标题】：Cannot map nested @Data with MapStruct无法使用 MapStruct 映射嵌套的 @Data
【发布时间】：2020-10-09 21:37:30
【问题描述】：

当尝试使用@Data 和@Builder 映射嵌套对象时，mapStruct 会抛出以下错误：“No read accessor found for property “profile” in target type。”

@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，但在尝试将两者结合时，在编译时抛出以下错误“目标类型中的属性“配置文件”未找到读取访问器。”

如果有人能在这方面帮助我，我将不胜感激。

非常感谢，
