使用Spring数据查询Redis中的嵌套对象

Question

@RedisHash("UserProfile")
public class UserProfile implements Serializable {
    @Id String id;
    @Reference PersonalInfo personalInfo = new PersonalInfo();
    @Reference BusinessInfo businessInfo = new BusinessInfo();
    ...
}

public class PersonalInfo {
    private String firstName;
    private String lastName;
    @Indexed private String userId;
    private ContactInfo contactInfo = new ContactInfo();
}

对我如何做这件事有什么建议吗？

更新：我将如下所示的方法添加到存储库中：

public interface UserProfileRepository extends CrudRepository<UserProfile, String> {
    List<UserProfile> findByPersonalInfo_UserId(String userId);
}

但是在代码中调用此方法时，我会得到以下错误。不确定我使用的Redis/Spring库是否有问题。我在用

null

当我执行findAll,findById时，它会返回结果。当我执行findByPersonalInfo_UserId()并传递像：Anthony.Turner或Ashleigh.Hayes这样的值时，什么也不会显示出来。我是否以不正确的格式给出了用户ID？我尝试了几种不同的方法，但都没有成功。

更新3：我还尝试删除UserProfile对象中的@Reference（这样redis对象就变平了，而不是指向引用）。但这也无济于事。

Answer 1

尝试用不带下划线的方式命名方法，如下所示：

List<UserProfile> findByPersonalInfoUserId(String userId);

有类似的情况，它对我有效。也不需要@reference注释。
