}
i dont know how to intialize subfields of comment field as i am begineer i am using elasticsearch 7.17.3我不知道如何初始化评论字段的子字段,因为我是初学者,我正在使用 elasticsearch 7.17.3
You can create a Comment
class like this:您可以像这样创建
Comment
class:
public class Comment {
@JsonProperty("c_id")
private String cId;
@JsonProperty("feed_id")
private String feedId;
@JsonProperty("c_text")
private String cText;
// Getters, setters, ...
}
and instead of using private String[] comment
, you should use:而不是使用
private String[] comment
,你应该使用:
@Field(type= FieldType.Nested , name="comment")
private List<Comment> comment;
