一、通过原生的Java代码操作ES
(1)运行环境：idea、maven3.5、spring
(2)pom.xml 文件中需要配置的工具包
<maven.compiler.source>1.8
<maven.compiler.target>1.8
<!--测试类架包-->
<groupId>junit
<artifactId>junit
<version>4.12
<scope>test
<!--ES 相关包-->
<groupId>org.elasticsearch
<artifactId>elasticsearch
<version>5.6.1
<groupId>org.elasticsearch.client
<artifactId>transport
<version>5.6.1
<!--日志相关包-->
<groupId>org.apache.logging.log4j
<artifactId>log4j-to-slf4j
<version>2.10.0
<groupId>org.apache.logging.log4j
<artifactId>log4j-core
<version>2.9.0
<groupId>org.slf4j
<artifactId>slf4j-api
<version>1.7.25
<groupId>org.slf4j
<artifactId>slf4j-simple
<version>1.7.21
<groupId>log4j
<artifactId>log4j
<version>1.2.12
<!--多导入一个包，否则报日志错误-->
<groupId>org.apache.logging.log4j
<artifactId>log4j-api
<version>2.9.1
<!--json数据相关包-->
<groupId>com.fasterxml.jackson.core
<artifactId>jackson-core
<version>2.8.1
<groupId>com.fasterxml.jackson.core
<artifactId>jackson-databind
<version>2.8.1
<groupId>com.fasterxml.jackson.core
<artifactId>jackson-annotations
<version>2.8.1
<!--spring Data框架相关包-->
<groupId>org.springframework.data
<artifactId>spring-data-elasticsearch
<version>3.0.5.RELEASE
<groupId>org.elasticsearch.plugin
<artifactId>transport-netty4-client
<groupId>org.springframework
<artifactId>spring-test
<version>5.0.5.RELEASE
</project>
（3）在resources文件夹创建applicationContext.xml配置文件
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:elasticsearch="http://www.springframework.org/schema/data/elasticsearch"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/data/elasticsearch
http://www.springframework.org/schema/data/elasticsearch/spring-elasticsearch-1.0.xsd">
cluster-nodes="127.0.0.1:9301,127.0.0.1:9302,127.0.0.1:9303"/>
</beans>
（4）创建一个实体(构建 ：无参构造、set、get方法)
@Document(indexName ="es_blog",type = "article")
public class Article {
@Id
@Field(type = FieldType.Long,store=true)
private long id;
@Field(type = FieldType.text,store=true,analyzer="ik_smart")
private String title;
（5）创建一个接口
package com.xcy.repositories;
import com.xcy.pojo.Article;
importorg.springframework.data.elasticsearch.repository.ElasticsearchRepository;
public interface ArticleRepository extendsElasticsearchRepository {
}
（6）测试
1.创建一个索引库
2.向索引库中插入数据
结果：
3.删除库中的数据
4.查询
