Java Spring数据mongodb控制器不工作

你好，我是新来的 我在模型中创建了两个文档 我使用Dbref表示关系 但当我添加数据时，我在文档中看不到它 就像我的一个文档中的收藏列表一样

病人文件中的咨询清单

我的模型使用Spring数据mongodb

Patient.java

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.DBRef;
import org.springframework.data.mongodb.core.mapping.Document;

import java.util.ArrayList;
import java.util.Collection;
import java.util.Date;

@Document(collection = "patients")
@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
public class Patient {
    @Id
    private String id;
    private String nom;
    private String prenom;

    @DBRef
    private Collection<Consultation> consultations=new ArrayList<>();

}

存储库

PatientRepository.java和ConsultationRepository.java
