【Spring Boot】Spring Boot之使用 Java High Level REST Client 整合elasticsearch

一、相关介绍

1）版本信息：

Java High Level REST Client 的版本为：7.4.2

elasticsearch： 7.4.2

注意：Java High Level REST Client的版本必须小于等于你的elasticsearch版本，建议版本一致

2）整合思路

1.通过注解在实体类上定义对应的index和mapping信息

2.通过spring事件监听器实现项目启动后，自动建立index和mapping

3.通过抽取base dao类，实现通用的es增删改查逻辑

4.提供部分常用的查询demo

3）GitHub地址

二、整合步骤

1）maven坐标

<dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>7.4.2</version>
            <exclusions>
                <exclusion>
                    <artifactId>elasticsearch</artifactId>
                    <groupId>org.elasticsearch</groupId>
                </exclusion>
                <exclusion>
                    <artifactId>elasticsearch-rest-client</artifactId>
                    <groupId>org.elasticsearch.client</groupId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>7.4.2</version>
            <scope>compile</scope>
        </dependency>
        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-client</artifactId>
            <version>7.4.2</version>
            <scope>compile</scope>
        </dependency>

2）自定义注解

1.@ESDocument

import java.lang.annotation.*;

/**
 * @author zhangboqing
 * @date 2019/12/12
 */
@Inherited
@Retention(RetentionPolicy.RUNTIME)
@Target({ ElementType.TYPE })
public @interface ESDocument {

    /**
     * Name of the Elasticsearch index.
     * <ul>
     * <li>Lowercase only</li>
     * <li><Cannot include \, /, *, ?, ", <, >, |, ` ` (space character), ,, #/li>
     * <li>Cannot start with -, _, +</li>
     * <li>Cannot be . or ..</li>
     * <li>Cannot be longer than 255 bytes (note it is bytes, so multi-byte characters will count towards the 255 limit
     * faster)</li>
     * </ul>
     */
    String indexName();

    /**
     * Number of shards for the index {@link #indexName()}. Used for index creation.
     */
    int shards() default 0;

    /**
     * Number of replicas for the index {@link #indexName()}. Used for index creation.
     */
    int replicas() default 0;
}

2.@ESField

/**
 * @author zhangboqing
 * @date 2019/12/12
 */
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.FIELD)
@Documented
@Inherited
public @interface ESField {

    @AliasFor("name")
    String value() default "";

    @AliasFor("value")
    String name() default "";

    ESFieldType type();

    String analyzer() default "";
}

3.@ESId

/**
 * @author zhangboqing
 * @date 2019/12/12
 */
@Retention(RetentionPolicy.RUNTIME)
@Target(value = { FIELD, METHOD, ANNOTATION_TYPE })
public @interface ESId {
}

3）定义的base类

1.BaseElasticsearchDao

/**

 */
@Data
public class ESPageRequest {

    private final int pageNo;
    private final int size;

    public ESPageRequest(int pageNo, int size) {

        if (pageNo < 0) {

        }

        this.pageNo = pageNo;

}

4.ESPageResult

/**

 * 分页结果
 */
@Data
public class ESPageResult<T> {

    private final long total;

    @Builder
    @Data
    public static class ESOrder implements Serializable {

        private final SortOrder direction;
        private final String property;

    }

}

4）定义的enum枚举类

1.ESFieldType

/**
 * @author zhangboqing
 * @date 2019/12/12
 */
public enum ESFieldType {
    Text("text"),

    }

    public String typeName;
}

5）自定义异常类

1.ApiException

public class ApiException extends RuntimeException {
    private ApiResponseCode responseCode;
    private IApiResponseCode iApiResponseCode;
    private ApiException.ErrorPrintLogLevelEnum errorPrintLogLevelEnum;
    private Integer code;

    }

    public ApiException(String message) {
        super(message);
    }

    public ApiException(String message, Throwable cause) {
        super(message, cause);
    }

    public ApiException(Throwable cause) {

 * @date 2019/12/10
 */
@Component
@Slf4j
public class ElasticsearchApplicationListener implements ApplicationListener<ContextRefreshedEvent>, ApplicationContextAware {

    @Autowired

                if (beanName.contains("com.zbq.springbootelasticsearch.common.elasticsearch.base.BaseElasticsearchDao")) {
                    continue;
                }
                Object bean = applicationContext.getBean(beanName);
                Class<?> targetBeanClass = bean.getClass();
                Class<?> beanClass = GenericTypeResolver.resolveTypeArgument(targetBeanClass, BaseElasticsearchDao.class);

    }

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.applicationContext = applicationContext;
    }
}

三、使用步骤

1）定义GoodsESEntity

/**
 * @author zhangboqing
 * @date 2019/12/10
 */
@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
@ESDocument(indexName = "goods")
public class GoodsESEntity {
    // 筛选条件包括：商品名称，品牌，规格，适用车型，商品编号，原厂编号

    /**
     * 主键,商品ID
     */
    @ESId
    @ESField(value = "goodsId",type = ESFieldType.Long)
    private Long goodsId;

    /**
     * 商品名称
     */
    @ESField(value = "goodsName",type = ESFieldType.Keyword)
    private String goodsName;
    /**
     * 品牌
     */
    @ESField(value = "goodBrand",type = ESFieldType.Keyword)
    private String goodBrand;
    /**
     * 规格
     */
    @ESField(value = "goodsSpec",type = ESFieldType.Keyword)
    private String goodsSpec;
    /**
     * 商品编号
     */
    @ESField(value = "goodsAccessoriesCode",type = ESFieldType.Keyword)
    private String goodsAccessoriesCode;
    /**
     * 原厂编号
     */
    @ESField(value = "goodsOriginalFactoryCode",type = ESFieldType.Keyword)
    private String goodsOriginalFactoryCode;

    /**
     * 复合字段，会被分词后存储
     */
    @ESField(value = "groupData",type = ESFieldType.Text,analyzer = "ik_smart")
    private String groupData;
}

2）定义GoodsESDao

/**
 * @author zhangboqing
 * @date 2019/12/10
 */
@Component
public class GoodsESDao<T extends GoodsESEntity> extends BaseElasticsearchDao<GoodsESEntity> {


    /**
     * 全文搜索查询
     * @param queryName
     * @return
     */
    public List<GoodsESEntity> findListByAnalysisForGroupData(String queryName) {
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        searchSourceBuilder.query(QueryBuilders.matchQuery("groupData",queryName));
        List<GoodsESEntity> search = search(searchSourceBuilder);
        return search;
    }

    /**
     * 多条件等值查询查询
     * @return
     */
    public List<GoodsESEntity> findListByEq() {
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
        boolQueryBuilder.filter(QueryBuilders.matchQuery("goodsName","保时捷跑车V10"));
        boolQueryBuilder.filter(QueryBuilders.matchQuery("goodBrand","国际1"));
        searchSourceBuilder.query(boolQueryBuilder);
        List<GoodsESEntity> search = search(searchSourceBuilder);
        return search;
    }

    /**
     * 多条件like查询查询
     * @return
     */
    public List<GoodsESEntity> findListByLike() {
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
        boolQueryBuilder.filter(QueryBuilders.wildcardQuery("goodsName","?V10"));
        boolQueryBuilder.filter(QueryBuilders.wildcardQuery("goodBrand","国际1"));
        searchSourceBuilder.query(boolQueryBuilder);
        List<GoodsESEntity> search = search(searchSourceBuilder);
        return search;
    }

    /**
     * 全文搜索查询分页排序
     * @param queryName
     * @return
     * QueryBuilders.boolQuery()
     */
    public ESPageResult findList(String queryName) {
        // 搜索条件
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        searchSourceBuilder.query(QueryBuilders.matchQuery("groupData",queryName));

        // 分页
        ESPageRequest esPageRequest = new ESPageRequest(1, 2);

        // 排序
        ESSort esSort = new ESSort(SortOrder.ASC,"goodsName");

        ESPageResult<GoodsESEntity> search = search(searchSourceBuilder, esPageRequest, esSort);
        return search;
    }
}

 3）配置属性

demo:
  data:
    elasticsearch:
    # es集群名称
      cluster-name: elasticsearch
    # es集群节点，多个逗号分隔 localhost:9200,localhost:9400
      cluster-nodes: localhost:9200
    # 设置创建index时，默认的分片规则
      index:
        number-of-shards: 3
        number-of-replicas: 2
    # 设置连接es的用户名和密码
      account:
        username: elastic
        password: 123456
