Spring boot中使用ElasticSearch的方法详解

0.版本选择

我这里选择了5.6.x，记得如果spring-boot-starter-parent是1.x可以选择2.x版本的elasticsearch，版本要对应，不然会有莫名其妙的问题

1.安装ElasticSearch

https://www.elastic.co/downloads/past-releases

windows 测试的，解压就能用

解压，到bin目录，双击elasticsearch.bat

1.1安装elasticsearch-head

https://github.com/mobz/elasticsearch-head

elasticsearch-head是一个网页查看elasticsearch状态，操作的第三方东西

git clone git://github.com/mobz/elasticsearch-head.git
cd elasticsearch-head
npm install
npm run start
open http://localhost:9100/

要先安装node.js

config/elasticsearch.yml 文件增加

http.cors.enabled: true
http.cors.allow-origin: “*”

elasticsearch-head/Gruntfile.js

connect: {
   server: {
    options: {
     hostname: '0.0.0.0',
     port: 9100,
     base: '.',
     keepalive: true
    }
   }
  }

8082改成你自己的端口

http://127.0.0.1:8082/swagger-ui.html#/

0是第一页

application.properties

#===es start===
spring.data.elasticsearch.repositories.enabled = true
spring.data.elasticsearch.cluster-nodes = 127.0.0.1:9300
#===es end===
