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

}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：
