很不幸的是，spring-data-elasticsearch支持elasticsearch版本太低
有两个方案: elasticsearch-rest-high-level-client和elasticsearch-rest-client-sniffer,本文用的elasticsearch-rest-high-level-client

  • Spring

    Spring 是一个开源框架，是于 2003 年兴起的一个轻量级的 Java 开发框架，由 Rod Johnson 在其著作《Expert One-On-One J2EE Development and Design》中阐述的部分理念和原型衍生而来。它是为了解决企业应用开发的复杂性而创建的。框架的主要优势之一就是其分层架构，分层架构允许使用者选择使用哪一个组件，同时为 JavaEE 应用程序开发提供集成的框架。
