ElasticSearch版本与Jar包冲突

本人之前在本地搭建了es2.4，然后使用spring-data-es创建elasticSearchTemplate进行crud操作。

这些完全没问题，然而一切问题在我连接公司的es之后就爆发了。

问题1:spring-data-es不支持5.*版本，所以自然会报错。

问题2:即便你不用spring-data-es，也会报错。因为spring-data-es 的maven文件必须要删除掉，对应的xml文件中的配置代码也要删掉。

解决办法，注释掉，下面的依赖

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-elasticsearch</artifactId>
    <version>3.0.8.RELEASE</version>
</dependency>

你所需要的依赖只有（服务器中的es版本也是5.1.2，要保持一致）

		<dependency>
		    <groupId>org.elasticsearch</groupId>
		    <artifactId>elasticsearch</artifactId>
		    <version>5.1.2</version>
		</dependency>
		
		<!--引入Redis服务,client必须和集群中node节点的版本一致  -->
	
        <dependency>
		    <groupId>org.elasticsearch.client</groupId>
		    <artifactId>transport</artifactId>
		    <version>5.1.2</version>
		</dependency>
