前沿
elasticsearch-rest-high-level-client在 7.15.0 中已弃用。
不推荐使用高级 REST 客户端,取而代之的是 Java API 客户端 。
spring-boot-starter-data-elasticsearch 也不推荐,虽然基础操作简化了很多,但是一旦使用了es高级特性,那么就如同进入了地狱,同时elasticsearch更新太快了spring-boot-starter-data-elasticsearch的版本根本就赶不上,导致升级会出现很多问题
现在在es官网推荐我们现在使用 Elasticsearch Java API 客户端
这个是相当于直接使用elasticsearch自身的接口Api所以不存在升级不兼容的问题
Java API 客户端官网地址
elasticsearch Api 操作大全 rest-api
需要的Maven
官网推荐依赖
经过各种的依赖冲突的解决,终于能跑起来了…

创建客户端
RestClient restClient = RestClient.builder(
new HttpHost("localhost", 9200)).build();
ElasticsearchTransport transport = new RestClientTransport(
restClient, new JacksonJsonpMapper());
//es 客户端
ElasticsearchClient client = new ElasticsearchClient(transport);
创建索引和映射分片等…
官方文档没有关于怎么设置映射和索引的配置的,自能自己研究,经过千辛万苦看底层源代码(一点注释都没有),了解代码编写的逻辑,经过我不懈的努力终于实现了以下的基础配置,其他的高级配置可以进行参考下配置进行扩展
//构建索引,并且起一个别名
CreateIndexResponse createResponse = client.indices()
.create(c -> c
.index("my-index") //创索引
.aliases("main-index", a -> a //创别名
.isWriteIndex(true)
)
// 映射字段属性
.mappings((m)-> m
.properties("name",Property.of(p->p.text(TextProperty.of(p1->p1.analyzer("ik_max_word").searchAnalyzer("ik_smart")))))
.properties("sku" ,Property.of(p->p.text(TextProperty.of(p1->p1.analyzer("ik_max_word").searchAnalyzer("ik_smart")))))
.properties("price",Property.of(p->p.integer(IntegerNumberProperty.of(p1->p1))) )
)
//设置分片 ,numberOfShards分片 ,Replicas副本
.settings((s)->s.numberOfShards("1").numberOfReplicas("2"))
);
System.out.println(createResponse.index());
自己进行二次封装
把官方文档看完后,我只想说一句,真难用, 经过3天的代码封装,基本能解决es的百分之90%的使用场景,代码压缩和简化程度至少优化了50%,同时保留了原有的代码特性, 特殊场景提供了对外客户端自己也可以进行二次开发,特殊的操作需要自己通过es的api接口手动进行修操作,在后端操作es一般就是增删改查数据,以及聚合,高亮等
结构
