前言
1.1. 集成方式
Spring Boot中集成Elasticsearch有4种方式：
本文用后面两种方式来分别连接并操作Elasticsearch
1.2. 环境与配置
服务端：elasticsearch-6.3.2 1台
客户端：elasticsearch 6.4.1
服务端配置文件：elasticsearch.yml
/etc/security/limits.conf
/etc/sysctl.conf
1.3. 版本
Spring Boot 2.0.5默认的elasticsearch版本很低，这里我们用最新版本6.4.1
如果启动过程中出现
则说明，elasticsearch依赖的jar包版本不一致，统一改成6.4.1即可
另外，Spring Boot 2.0.5依赖的spring-data-elasticsearch版本是3.0.1，需要升级到3.1.0

也许，大家会疑惑，配置文件中明明写的端口是9200，为何这里配置文件中连接的时候写的端口是9300呢？
因为，配置9200是通过HTTP连接的端口，9300是TCP连接的端口
