无法在 Spring Boot Hibernate Search Elasticsearch 中配置我自己的分析器

阿兰·B

请帮忙。我尝试在 Spring Boot 应用程序中配置弹性搜索索引已经很多天了，当然我错过了文档中的某些内容，但我没有找到。

我对 spring 比较陌生，几天后我发现它非常强大，这是我的第一个很长的问题。

问题描述我有一个简单的对象 Book 在我自己的分析器上用 @FullTextField 索引

@Entity
@Indexed
@Data
public class Book {
    @Id
    @GeneratedValue
    private Long id;

    @FullTextField(analyzer = "my_analyze_french")
    private String name;

用我的配置

package com.mycompany.jpa.elasticsearch;
import org.hibernate.search.backend.elasticsearch.analysis.ElasticsearchAnalysisConfigurationContext;
import org.hibernate.search.backend.elasticsearch.analysis.ElasticsearchAnalysisConfigurer;

// https://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#getting-started-analysis
public class CVAnalysisConfigurer implements ElasticsearchAnalysisConfigurer {
    @Override
    public void configure(ElasticsearchAnalysisConfigurationContext context) {
        System.out.println("DEFINE a NEW ANALYZER");
        // define each analyzer + associated token filter parameters
        context.analyzer("my_analyze_french").custom()
                .tokenizer("standard")
                .tokenFilters("lowercase", "snowball_french", "asciifolding"); // warning order

        // stemmer for french : regroup words by family
        context.tokenFilter("snowball_french")
                .type("snowball")
                .param("language", "French");

        System.out.println("DEFINE a NEW ANALYZER:DONE");
    }
}

在我的application.propertiesi 中指明 bean 的名称来配置我的分析器

# cf https://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#backend-elasticsearch-analysis
hibernate.search.backend.analysis.configurer=class:com.mycompany.jpa.elasticsearch.CVAnalysisConfigurer

当我启动我的应用程序时出现错误

我的配置我使用 spring Boot 2.3.11，我的数据库如果是 h2

主要依赖是

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <!-- for use of elastic search, automatic indexation with jpa -->
    <dependency>
        <groupId>org.hibernate.search</groupId>
        <artifactId>hibernate-search-mapper-orm</artifactId>
        <version>6.0.4.Final</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate.search</groupId>
        <artifactId>hibernate-search-backend-elasticsearch</artifactId>
        <version>6.0.4.Final</version>
    </dependency>

我指定了弹性搜索的版本

<properties>
    <elasticsearch.version>7.13.2</elasticsearch.version>
</properties>

我的服务器版本是一样的，我使用一个简单的 docker 来测试，我在每次启动之前从卷中删除节点

version: '3'
services:
  elasticsearchstudy:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.13.2
    container_name: elasticsearchstudy
    environment:
      - "discovery.type=single-node"
    volumes:
      - ./elasticsearch:/usr/share/elasticsearch/data:rw
    ports:
      - 9200:9200
    restart: unless-stopped

我试过什么？为了避免 Spring Boot 可能出现的一些问题，我尝试推迟引导，但无论有没有它都没有改变

@SpringBootApplication
@EnableJpaRepositories(bootstrapMode = BootstrapMode.DEFERRED)
public class HibernateSearchStudy {

我尝试在 Postman 上使用 REST API 配置我的分析，当我处理使用 REST API 创建的新索引时可以分析文档，localhost:9200/book/_analyze但无法在我的应用程序索引 Book-000001 上执行此操作（我无法修改先前创建的索引的分析器）

首先，我尝试在 a 中完成所有操作，@DataJpaTest但由于它不起作用（相同的错误），我现在尝试在 CommandLineRunner 中对其进行测试，该 CommandLineRunner 在我的存储库中插入数据，然后进行搜索

我认为我的ElasticsearchAnalysisConfigurer初始化从未被调用（我输入的跟踪configure从未出现）。怎么办？

任何帮助将不胜感激！！

application.properties是 Spring Boot 配置文件，而不是 Hibernate Search 配置文件。您不能只是在那里转储 Hibernate Search 属性。

相反，在您的 Hibernate Search 属性前加上spring.jpa.properties.，以便 Spring Boot 将这些属性传递给 Hibernate ORM，Hibernate ORM 将它们传递给 Hibernate Search。例如：

# cf https://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#backend-elasticsearch-analysis
spring.jpa.properties.hibernate.search.backend.analysis.configurer=class:com.mycompany.jpa.elasticsearch.CVAnalysisConfigurer
