ES动态索引——日志es索引数据按月份存储

一、定义ES索引

@NoArgsConstructor
@AllArgsConstructor
@Data
@Accessors(chain = true)
@Document(indexName = "charge_pile_log" + Constants.ES_TIME_DYNAMIC_INDEX) //(索引名称动态，前面固定，后面月份)
public class ChargePileLogESDomain {@Idprivate String id;@Field(type = FieldType.Integer)private Integer businessType;
}public static final String ES_TIME_DYNAMIC_INDEX = "-#{ T(com.energy.cloud.log.service.util.DateUtil).getUTCMonth() }";

二、定义Repository

import com.energy.cloud.log.service.domain.ChargePileLogESDomain;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;public interface ChargePileLogRepository extends ElasticsearchRepository<ChargePileLogESDomain, String> {
}

三、存储数据

 @Resourceprivate ChargePileLogRepository chargePileLogRepository;List<ChargePileLogESDomain> saveList = new ArrayList<>();
chargePileLogRepository.saveAll(saveList);

四、查询数据（索引名称带通配符）

SearchRequest request = new SearchRequest(charge_pile_log*);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
request.source(searchSourceBuilder);
SearchResponse searchResponse = restHighLevelClient.search(request, RequestOptions.DEFAULT);

五、常量类和工具类

public static final String ES_TIME_DYNAMIC_INDEX = "-#{ T(com.energy.cloud.log.service.util.DateUtil).getUTCMonth() }";public class DateUtil {public static String getUTCMonth(){//设置日期格式为yyyy-mmDateTimeFormatter fmt = DateTimeFormat.forPattern("yyyy-MM");//获取拾取为UTC的时间DateTime now = DateTime.now(DateTimeZone.UTC);return fmt.print(now);}
}
