配置参数

spring:
  elasticsearch:
    uris: http://XXXX:9200
    username: elastic
    password: 'XXXX'

定义Entity

@Data
@Document(indexName = "resource_index")
public class ResourceEntity {
    @Id
    private 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 = {""}, postTags = {""}, numberOfFragments = 0)
    )
    List<SearchHit<ResourceEntity>> findByTitle(String title);
}

分页查询

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

测试

    @Test
    public void findByTitleTest(){


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

    }
