springboot 集成elasticsearch遇到的坑

最近開始學習elasticsearch，因此就想着在springboot裏面集成一下elasticsearch，結果遇到了很多麻煩，下面總結一下，希望你們和本身之後都少走彎路

首先聲明下，本人開始學習elasticsearch的時候，官網最新版本已經更新到了5.6.x，本人用的是5.1.1，Springboot的穩定版本已經到了1.5.8

1.直接集成spring-boot-starter-data-elasticsearch ，項目能啓動，可是控制檯輸出一直鏈接不上

後來發現終端的elasticsearch服務器在springboot啓動的時候也有打印信息

仔細分析後發現有一句話很重要

Received message from unsupported version: [2.0.0] minimal compatible version is: [5.0.0]
複製代碼

大概意思就是接收到不支持的2.0版本，目前的最小穩定版本已是5.0 後來分析了springboot的maven依賴發現的確如此

而後我第一想到的解決辦法就是更改springboot的maven依賴的elasticsearch版本

2.修改maven的elasticsearch後，找不到方法

我修改了maven的依賴

<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
		<elasticsearch.version>5.1.1</elasticsearch.version>
	</properties>
複製代碼

也的確生效了

可是啓動直接報錯

而後網上查了相關資料，發現是因爲springboot1.5.x原本引用的是es2.0.0，可是es5.0.0之後有些方法已經刪除了，因此這裏直接修改es版本以後會報方法找不到的異常 具體請參考 www.cnblogs.com/slimer/p/56…

• 3.解決

無奈之下只好又下載了es2.4.5的版本，問題解決

若是就想用es5.x的版本那目前只能等待springboot更新了，或者本身引入org.elasticsearch.client的依賴，本身封裝接口了

springboot集成elasticsearch的案例請參考 blog.csdn.net/tianyaleixi… blog.csdn.net/gebitan505/… 本身引入依賴的elasticsearch的使用請參考 www.cnblogs.com/wenbronk/p/… github.com/MarkGao1152…
