实体类中的 IndexQueryBuilder 方法导致“无法索引文档 [id: 1]" [英] IndexQueryBuilder method inside entity class results in "failed to index the document [id: 1]"

问题描述

我收到此错误:

org.springframework.data.elasticsearch.ElasticsearchException:失败索引文档 [id: 1]

org.springframework.data.elasticsearch.ElasticsearchException: failed to index the document [id: 1]

在org.springframework.data.elasticsearch.core.ElasticsearchTemplate.prepareIndex(ElasticsearchTemplate.java:1028)在org.springframework.data.elasticsearch.core.ElasticsearchTemplate.index(ElasticsearchTemplate.java:525)...

at org.springframework.data.elasticsearch.core.ElasticsearchTemplate.prepareIndex(ElasticsearchTemplate.java:1028) at org.springframework.data.elasticsearch.core.ElasticsearchTemplate.index(ElasticsearchTemplate.java:525) ...

每次我在实体 Book 类中放入一个 getIndexQuery 方法.所以它看起来像这样:

Every time that I put inside my entity Book class a getIndexQuery method. So it look like this:

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@Builder
@Document(indexName = "bookshop", type = "book", shards = 1, replicas = 0, refreshInterval = "-1")
public class Book  {

    @Id
    private String bookId;

    @Field(type = FieldType.String, store = true)
    private String title;

    public IndexQuery getIndexQuery(){
        return new IndexQueryBuilder().withId(this.getBookId()).withObject(this).build();
    }

}

即使我没有在代码中使用此方法，也会发生错误.如何将此方法放入我的实体类中，而不会弄乱实体模式(因为我认为这是错误的)?

The error occurs even when I do not use this method anyware in my code. How can I put this method inside my entity class without it messing with the enitties schema (becouse that is what I assume what is wrong)?

推荐答案

使用 @JsonIgnore.

@JsonIgnore
public IndexQuery getIndexQuery(){
    return new IndexQueryBuilder().withId(this.getBookId()).withObject(this).build();
}

com.fasterxml.jackson.annotation.JsonIgnore 来自 jackson-core-2.8.1.jar 或添加此依赖项.

com.fasterxml.jackson.annotation.JsonIgnore is from jackson-core-2.8.1.jar or add this dependency.

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.8.1</version>
</dependency>
