springboot3 集成elasticsearch(es)客户端(高亮查询)

集成依赖

<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>3.2.5</version><relativePath/> <!-- lookup parent from repository --></parent><dependencies></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-elasticsearch</artifactId></dependency></dependencies>

配置参数

spring:elasticsearch:uris: http://XXXX:9200username: elasticpassword: 'XXXX'

定义Entity

@Data
@Document(indexName = "resource_index")
public class ResourceEntity {@Idprivate String id;@Field(type = FieldType.Text, analyzer = "ik_max_word", searchAnalyzer = "ik_max_word")private String title;public ResourceEntity() {}public ResourceEntity(String id, String title) {this.id = id;this.title = title;}
}

定义Repository

public interface ResourceEntityRepository extends ElasticsearchRepository<ResourceEntity, String> {@Highlight(fields = {@HighlightField(name = "title")},parameters = @HighlightParameters(preTags = {"<span style='color:red'>"}, postTags = {"</span>"}, numberOfFragments = 0))List<SearchHit<ResourceEntity>> findByTitle(String title);
}

分页查询

@Highlight(fields = {@HighlightField(name = "title")},parameters = @HighlightParameters(preTags = {"<span style='color:red'>"}, postTags = {"</span>"}, numberOfFragments = 0))ist<SearchHit<ResourceEntity>> findByTitle(String title, Pageable pageable);
}

测试

    @Testpublic void findByTitleTest(){List<SearchHit<ResourceEntity>> testEntityList = repository.findByTitle("文档");testEntityList.forEach(testEntity -> {log.info("testEntity:{}",testEntity);});}
