RestTemplate:模拟发 HTTP 请求,ES 很多操作需要自己封装,麻烦 HttpClient:同上 Elasticsearch-Rest-Client:官方 RestClient,封装了 ES 操作,API 层次分明,上手简单最终选择Elasticsearch-Rest-Client(elasticsearch-rest-high-level-client) https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-r...
Elasticsearch 的API 分为 REST Client API(http请求形式)以及transportClientAPI两种。相比来说transportClient API效率更高,transportClient 是通过Elasticsearch内部RPC的形式进行请求的,连接可以是一个长连接,相当于是把客户端的请求当成 Elasticsearch 集群的一个节点,当然 REST Client API 也支持http keepAlive形式的长...
RestClient.builder( httpHosts ) ); } } 至此Springboot与Elasticsearch的集成已经结束,接下来就是使用了。 5、使用RestClient API 下文演示常规场景下的RestClient API的使用方式和对应的DSL语法,涉及到的相关完整代码见如下地址: 代码地址:https://github.com/yclxiao/spring-elasticsearch.git ...
JsetClient:非官方,更新缓慢 RestTemplate:模拟发送Http请求,ES很多的操作需要我们自己来封装,效率低 HttpClient:和上面的情况一样 ElasticSearch-Rest-Client:官方的RestClient,封装了ES的操作,API层次分明,易于上手。 JavaAPIClient 7.15版本后推荐 2.ElasticSearch-Rest-Client整合 ...

简介:SpringBoot整合elasticsearch-rest-client实战 前言 很多人在Spring boot项目中都已经习惯采用Spring家族封装的spring-data-elasticsearch来操作elasticsearch,而官方更推荐采用rest-client。 今天给大家介绍下在spring boot中如何整合rest-client操作elasticsearch。
