驾校报名网站怎么做优化网站排名如何

ELK 这一套的版本更迭很快，
而且es常有不兼容的东西出现，
经常是搜一篇文章，看似能用，拿到我这边就不能用了。
很是烦恼。
我这边的ELK版本目前是 6.8.18，这次的操作记录一下。

（涉密内容略有删改，一看便知）

es版本信息：

{"name" : "es-client1","cluster_name" : "xt-logs-view","cluster_uuid" : "xxxxxxxxxxxx-UNg","version" : {"number" : "6.8.18","build_flavor" : "default","build_type" : "docker","build_hash" : "aca2329","build_date" : "2021-07-28T16:06:05.232873Z","build_snapshot" : false,"lucene_version" : "7.7.3","minimum_wire_compatibility_version" : "5.6.0","minimum_index_compatibility_version" : "5.0.0"},"tagline" : "You Know, for Search"
}

创建一个index，指定字段为date类型

kibana中的命令：

PUT my_index
{"mappings": {"_doc": {"properties": {"createTime": {"type":   "date","format": "yyyy-MM-dd HH:mm:ss"},"updateTime": {"type":   "date","format": "yyyy-MM-dd HH:mm:ss"}}}}
}

结合java项目中的类型

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class MyIndex implements Serializable {//其他字段略/*** 创建时间*/@Field(type = FieldType.Date,format = DateFormat.custom,pattern = "yyyy-MM-dd HH:mm:ss")@JSONField(format = "yyyy-MM-dd HH:mm:ss")private Date createTime;/*** 更新时间*/@Field(type = FieldType.Date,format = DateFormat.custom,pattern = "yyyy-MM-dd HH:mm:ss")@JSONField(format = "yyyy-MM-dd HH:mm:ss")private Date updateTime;
}

java写入es （springboot）

        <dependency><groupId>org.elasticsearch.client</groupId><artifactId>elasticsearch-rest-high-level-client</artifactId><version>6.8.18</version></dependency><dependency><groupId>org.springframework.data</groupId><artifactId>spring-data-elasticsearch</artifactId>           <version>3.1.11.RELEASE</version></dependency>

客户端配置

spring:data:elasticsearch:rest:uris: http://172.16.100.1:9200,http://172.16.100.2:9200,http://172.16.100.3:9200

@Data
@Configuration
public class ElasticSearchConfig {@Value("${spring.data.elasticsearch.rest.uris}")private String[] uris;@Beanpublic RestHighLevelClient restHighLevelClient() {//单机版//return new RestHighLevelClient(RestClient.builder(new HttpHost(host, port, "http")));//集群版HttpHost[] httpHosts = Arrays.stream(uris).map(HttpHost::create).toArray(HttpHost[]::new);//集群版RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(httpHosts));return client;}
}

kibana创建索引模式

创建索引模式

创建的索引模式里，终于可以指定某字段为时间字段了，从而可以使用时间范围搜索。

可按时间范围查
