elasticsearch的使用（三）——SpringBoot2.x整合elasticsearch5.x

介绍

自己在整合的过程中因为版本的不一致差点嗝屁，试了好久才可以使用，本次项目里面使用的SpringBoot版本是2.0x的，因为ES的依赖是强依赖的，所以各个依赖的版本也需要一并更新。

环境配置：

系统配置

Centos7

环境配置

elasticsearch5.5，

springboot2.0

 

SpringDataElasticsearch以及SpringBoot集成

解决依赖的问题

springboot的父依赖如下

     org.springframework.boot
     spring-boot-starter-parent
     2.0.0.RELEASE
      

点击去，看到 版本为5.6.8，但是我们的搜索服务是5.5.0，所以要设置为5.5.0

5.6.8

依赖选择
