ES5.6.16客户端连接报错java.lang.ClassNotFoundException: org.elasticsearch.http.AbstractHttpServerTransport

ES5.6.16客户端连接报错java.lang.ClassNotFoundException: org.elasticsearch.http.AbstractHttpServerTransport 背景

一直依赖都是用spring-data-elasticsearch，今天项目上突然有一个需求，要以SpringMVC的方式引入es client；

解决方案

先在pom中添加相应版本的elasticsearch依赖：

    org.elasticsearch
    elasticsearch
    5.6.16
    
        
            commons-logging
            commons-logging
        
    

添加这个之后如果还不能解决问题，再在pom中添加transport-netty4-client依赖：

    org.elasticsearch.plugin
    transport-netty4-client
    5.6.16

因为在报错中会有那么一句，表示版本冲突；
