SpringBoot整合Elasticsearch详细步骤以及代码示例（附源码）

准备工作 环境准备

JAVA版本

java version "1.8.0_121" Java(TM) SE Runtime Environment (build 1.8.0_121-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

ES版本

{ "name": "pYaFJhZ", "cluster_name": "my-cluster", "cluster_uuid": "oC28y-cNQduGItC7qq5W8w", "version": { "number": "6.8.2", "build_flavor": "oss", "build_type": "tar", "build_hash": "b506955", "build_date": "2019-07-24T15:24:41.545295Z", "build_snapshot": false, "lucene_version": "7.7.0", "minimum_wire_compatibility_version": "5.6.0", "minimum_index_compatibility_version": "5.0.0" }, "tagline": "You Know, for Search" }

SpringBoot版本

2.1.7.RELEASE

开发工具使用的是IDEA

安装ES

Elasticsearch介绍以及安装：ElasticSearch入门-基本概念介绍以及安装

开始 创建SpringBoot项目

打开IDEA，在菜单中点击
File > New > Project...
在弹框中选择Spring Initializr

然后Next

填写项目名等，然后Next，

选择依赖的jar包（一般我只选Lombok，其他的自己手动加），然后Next。

最后选择项目所在路径，点击Finish。

搞定收工。至此，一个新的SpringBoot项目就新鲜出炉了。

POM文件

当然，具体依赖的jar包肯定不止第2步选择的那些，其中SpringBoot提供的操作ES的jar包spring-boot-starter-data-elasticsearch当然也是必不可少的。

这里贴出最终的pom文件：
