ElasticSearch5.4.3 环境搭建 2017 (5-Java Client Security Api x-pack)

完成基本的配置以后，下面使用java client api进行简单的开发测试。

官方教程：噗嗤

1. Maven 依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.tom.es</groupId><artifactId>ElasticSearch0100</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>ElasticSearch0100</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><spring.version>4.1.0.RELEASE</spring.version><slf4j.version>1.5.10</slf4j.version><slf4j-log4j12.version>1.6.1</slf4j-log4j12.version><java.version>1.8</java.version><junit.version>4.12</junit.version><org.aspectj-version>1.8.1</org.aspectj-version></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>${junit.version}</version><scope>test</scope></dependency><!-- ES dependency for query builder --><dependency><groupId>org.elasticsearch</groupId><artifactId>elasticsearch</artifactId><version>5.4.2</version></dependency><dependency><groupId>org.elasticsearch.client</groupId><artifactId>transport</artifactId><version>5.4.3</version></dependency><!-- slf4j-log --><dependency><groupId>org.apache.logging.log4j</groupId><artifactId>log4j-to-slf4j</artifactId><version>2.8.2</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>1.7.24</version><scope>test</scope></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>1.7.24</version></dependency>                   <!-- add the x-pack jar as a dependency -->      <dependency>         <groupId>org.elasticsearch.client</groupId>         <artifactId>x-pack-transport</artifactId>         <version>5.4.3</version>      </dependency></dependencies></project>

官方那个repository好像不能用，所以我只加了依赖，在未启用x-pack的elasticsearch上，使用上面那个transport依赖即可，但是启用x-pack安全认证之后，需要使用x-pack-transport的依赖。

注意要添加下面的repository , 不然pom报错，找不到x-pack-transport

<!-- add the elasticsearch repo -->      <repository>         <id>elasticsearch-releases</id>         <url>https://artifacts.elastic.co/maven</url>         <releases>            <enabled>true</enabled>         </releases>         <snapshots>            <enabled>false</enabled>         </snapshots>      </repository>

2. 示例代码

package com.tom;import java.io.IOException;import java.net.InetSocketAddress;import org.elasticsearch.action.index.IndexResponse;import org.elasticsearch.client.transport.TransportClient;import org.elasticsearch.common.settings.Settings;import org.elasticsearch.common.transport.InetSocketTransportAddress;import org.elasticsearch.common.xcontent.XContentBuilder;import org.elasticsearch.common.xcontent.XContentFactory;import org.elasticsearch.common.xcontent.XContentType;import org.elasticsearch.xpack.client.PreBuiltXPackTransportClient;import org.junit.After;import org.junit.Before;import org.junit.Test;public class TestXPackTransportClient {TransportClient client = null;@SuppressWarnings("resource")@Beforepublic void before() {client = new PreBuiltXPackTransportClient(Settings.builder().put("cluster.name", "test_es")//集群名称.put("node.name", "node-115")//加一个节点.put("client.transport.sniff", true)//自动探测.put("xpack.security.user", "elastic:密码")//xpack的用户.build()).addTransportAddress(new InetSocketTransportAddress(new InetSocketAddress("ip或者域名", 9300)));//地址1，可以加多个}@Afterpublic void after() {if (client != null) {client.close();}}@Testpublic void testIndex() throws IOException {XContentBuilder contentBuilder = XContentFactory.jsonBuilder().startObject();contentBuilder.field("id", "2017_06_01");contentBuilder.field("name", "KingKong");contentBuilder.field("director", "tom");contentBuilder.field("year",   "2017");String json = contentBuilder.endObject().string();IndexResponse resp = client.prepareIndex("movies", "film").setSource(json, XContentType.JSON).get();System.out.println(resp.toString());}}

执行输入如下：

命令行查一下：OK的
