我有以下用于在solr文档上执行CRUD操作的mvc spring项目，我能够成功创建，读取，更新和删除，但是当我添加一些子文档时，事情变得有些混乱，例如我将新文档保存为json格式，但会保存它，但是当我查询它时，子文档将分别返回，而在主文档中则将其声明为空。
这就是我要做什么：
主要文件：
@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
@SolrDocument(collection = "movie")
public class Movie {
@Id
private long id;
@Indexed
private String title;
@Indexed
private List<Long> genreId;
@Indexed
private List<Genre> genre;
@Indexed(required = true, stored = true)
@ChildDocument
private List<Person> director;
@Indexed
private Date releaseDate;
@Indexed(required = true, stored = true)
@ChildDocument
private List<Person> distributor;
@Indexed
private MovieLanguage language;
@Indexed(required = true, stored = true)
@ChildDocument
private List<Person> actor;
@Indexed(required = true, stored = true)
@ChildDocument
private List<Person> creator;
@Indexed
private long duration;
}
子文档：
@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
public class Person implements Serializable {
@Id
private int id;
@Indexed
private String firstName;
@Indexed
private String lastName;
@Indexed
@ChildDocument
private List<Role> role;
}
@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
public class Role implements Serializable {
@Id
private int id;
@Indexed
private String name;
}
其余的Spring类（存储库，服务和受控类）除了默认值外没有任何事务。
这是我的要求：
{

"title": "movie",
"genreId": [
1,
3,
4

"Comedy",
"Drama"
],

有人可以解释为什么我的文档中有多个空数据，以及为什么actor，director，creator和distributed字段为空吗？
