Elasticsearch 在企業裏落地的場景愈來愈多了,可是你們在項目裏使用 Elasticsearch的姿式也是千奇百怪,此次正好本身須要使用,因此乾脆就封裝一個 elasticsearch-spring-boot-starter以供複用好了。若是不知道 spring-boot-starter該如何製做,能夠參考文章《如何自制一個Spring Boot Starter並推送到遠端公服》,下面就來簡述一下自制的 elasticsearch-spring-boot-starter該如何使用。java
<dependency>
<groupId>com.github.hansonwang99</groupId>
<artifactId>elasticsearch-spring-boot-starter</artifactId>
<version>0.0.8</version>

若是你尚未一個屬於本身的 Elasticsearch集羣,能夠參考文章 《CentOS7 上搭建多節點 Elasticsearch集羣》來一步步搭建之,本文實驗所用的集羣即來源於此。git
elasticsearch:
host: 192.168.31.75
httpPort: 9200
tcpPort: 9300
clusterName: codesheep
docFields: title,filecontent
auth:
enable: false
複製代碼
各個字段解釋以下:github
host
:Elasticsearch 節點地址httpPort
: Elasticsearch REST端口tcpPort
:Elasticsearch TCP端口clusterName
:集羣名docFields
:文檔字段,以英文逗號間隔,好比我這裏的業務場景是文檔包含 標題(title)
和 內容(filecontent)
字段auth
:是否須要權限認證因爲我這裏安裝的實驗集羣並沒有 x-pack
權限認證的加持,所以無需權限認證,實際使用的集羣或者阿里雲上的 Elasticsearch集羣均有完善的 x-pack
權限認證,此時能夠加上用戶名/密碼的配置:spring
elasticsearch:
host: 192.168.199.75
httpPort: 9200
tcpPort: 9300
clusterName: codesheep
docFields: title,filecontent
auth:
enable: true
username: elasticsearch
password: xxxxxx

這些都是在 elasticsearch-spring-boot-starter中定義的json
public String createIndex() throws IOException {
IndexModel indexModel = new IndexModel();
indexModel.setIndexName("testindex2"); // 注意索引名字必須小寫,不然ES拋異常
indexModel.setTypeName("testtype2");
indexModel.setReplicaNumber( 2 ); // 兩個節點,所以兩個副本
indexModel.setShardNumber( 3 );
