加上了@Document注解之后，默认情况下这个实体中所有的属性都会被建立索引、并且分词。
indexName索引名称 理解为数据库名 限定小写
type 理解为数据库的表名称
shards = 5 默认分区数
replicas = 1 每个分区默认的备份数
refreshInterval = "1s" 刷新间隔
indexStoreType = "fs"  索引文件存储类型

@Document(indexName = "requestlogindex",type = "requestlog")
public class RequestLog {//Id注解Elasticsearch里相应于该列就是主键，查询时可以使用主键查询@Idprivate Long id;private String orderNo;private String userId;private String userName;private String createTime;
