ElasticSearch6.3.2开启x-pack后客户端调用
问题:在ElasticSearch6.3.2开启x-pack后如何使用java客户端访问?
ElasticSearch6.3.2 java客户端调用
这里引入的是spring-boot-starter-data-elasticsearch(底层用的也是TransportClient)
开启x-pack后需要用到x-pack-transport(官网文档版本是6.2.4-这里有详细介绍)
ElasticSearch6.3版本已经安装了x-pack x-pack默认已经安装位置
/usr/local/software/elasticsearch-6.3.2/modules
license时间是一个月
curl -XGET -u elastic:ilikees2019 'http://127.0.0.1:9200/_license'
集成过程记录如下:
1、pom.xml文件
这里使用springboot版本是2.1.3.RELEASE
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<!--spring data 操作es-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
<!--add the x-pack 及依赖 开始-->
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>x-pack-transport</artifactId>
<version>${elasticsearch.version}</version>
</dependency>
<dependency>
<groupId>com.unboundid</groupId>
<artifactId>unboundid-ldapsdk</artifactId>
<version>3.2.0</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>x-pack-core</artifactId>
<version>6.3.2</version>
</dependency>
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15on</artifactId>
<version>1.65</version>
</dependency>
<!--add the x-pack 及依赖 结束-->
x-pack-core.jar可以从/usr/local/software/elasticsearch-6.3.2/modules/x-pack/x-pack-core/x-pack-core-6.3.2.jar 下载到本地maven库中
其他依赖与安全认证的算法包如bouncycastle等也需要自己引入下
2、创建XPackClient
@Bean
public TransportClient getTransportClient() throws UnknownHostException{
Settings.Builder builder = Settings.builder();
builder.put("cluster.name", "myClusterName");//集群名称
builder.put("client.transport.sniff", true);//自动嗅探整个集群的状态,把集群中其他ES节点的ip添加到本地的客户端列表中
builder.put("xpack.security.transport.ssl.enabled", false);//设置xpack ssl这里设置为false
builder.put("xpack.security.user", "xxxxx");//集群设置的密码
builder.build()
TransportClient transportClient = new PreBuiltXPackTransportClient(settings())
.addTransportAddress(new TransportAddress(InetAddress.getByName("xxxxx"), 9300));//集群的ip地址
log.info("transportClient.listedNodes():{}",transportClient.listedNodes());
log.info("ElasticsearchXPackClient 启动成功");
return transportClient;
}
3、测试使用
因为上面pom.xml文件中用的是spring-boot-starter-data-elasticsearch 所以也可以直接使用ElasticsearchRepository,最后调用的还是配置的TransportClient
@Autowired
private TransportClient transportClient;
@Test
public void testFindEsTransport() {
// 发起请求得到响应
GetResponse response=transportClient.prepareGet("bank","account","9").get();
System.out.println(response.getSource());
}
