官网文档maven只需引入
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>6.4.0</version>
</dependency>
但是 连接出错：
Exception in thread "main" java.lang.NoClassDefFoundError: org/elasticsearch/common/xcontent/DeprecationHandler
at com.lv.springboot.datasource.ClientUTis.main(ClientUTis.java:13)
Caused by: java.lang.ClassNotFoundException: org.elasticsearch.common.xcontent.DeprecationHandler

偶发现
不知为何会出现这样! 希望知情的小伙伴能够告知！
于是乎：
引入：
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>6.4.0</version>
</dependency>
问题解决
