SpringBoot集成ElasticSearch实现模糊搜索作者：王帅@CodeSheep管线电伴热
实验环境
ES 版本：5.3.0
Spring Boot 版本：1.5.9
⾸先当然需要安装好 Elastic Search 环境，最好再安装上可视化插件 elasticsearch-head来便于我们直观地查看数据。Spring⼯程创建 这部分没有特殊要交代的，但有⼏个注意点⼀定要当⼼
注意在新建项⽬时记得勾选web和NoSQL中的Elasticsearch依赖，来张图说明⼀下吧：
项⽬⾃动⽣成以后l中会⾃动添加spring-boot-starter-data-elasticsearch的依赖：
<dependency>
ei硅钢片<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
本项⽬中我们使⽤开源的基于restful的es java客户端jest，所以还需要在l中添加jest依赖：
<dependency>
<groupId>io.searchbox</groupId>
<artifactId>jest</artifactId>
</dependency>
除此之外还必须添加jna的依赖：
<dependency>
<groupId>net.java.dev.jna</groupId>
<artifactId>jna</artifactId>
</dependency>
否则启动spring项⽬的时候会报JNAnotfound.nativemethods will be disabled.的错误：
项⽬的配置⽂件l中需要把es服务器地址配置对
server:
port: 6325
spring:
elasticsearch:
jest:
uris:
- 113.209.119.170:9200 # ES服务器的地址！
read-timeout: 5000
我的项⽬代码组织如下：
各部分代码详解如下，注释都有：
