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 {

    @Id
    private 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

 @Resource
 private 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-mm
        DateTimeFormatter fmt = DateTimeFormat.forPattern("yyyy-MM");
        //获取拾取为UTC的时间
        DateTime now = DateTime.now(DateTimeZone.UTC);
        return fmt.print(now);
    }
}
