本文档描述了在SpringBoot项目中集成Elasticsearch时遇到的两个问题：1）使用嵌入式节点启动，节点未加入到集群；2）通过TransportClient建立Client，程序启动后持续报错。错误信息显示程序无法获取节点信息，可能原因是版本不匹配或配置问题。解决方案可能涉及检查版本兼容性、配置文件设置以及网络通信状况。

在 spring boot 项目中即成集成 elasticsearch(dao层数据与es交互使用的的是 spring-data-elasticsearch)首先安装了服务器端的 es 服务，和 head 插件，es 服务启动正常，node-1 为默认主节点，my-cluster 为集群名，如图：

在程序中，使用嵌入式node启动节点正常，方式如下：

Node node = NodeBuilder.nodeBuilder().node();

node.start();

但是，如果使用 TransportClient 建立 es 的 Client，方式如下：

TransportClient client = new TransportClient(settings);

client.addTransportAddress(new InetSocketTransportAddress("127.0.0.1", 9300));

使用 TransportClient 方式，启动程序后，程序可以正常启动，但是控制台一直不停报错，貌似是在一直监测节点，而节点一直没有被发现，所以不停报错，错误信息如下，应用程序控制台错误信息：

而且，当我使用嵌入式node启动节点后，系统会自动启动一个node节点，node.name 也是随机的，并且并没有将该节点加入启动的es集群中，我加入的索引和数据也不能出现在 my-cluster 集群中

所以有两个问题：

1、为什么我使用嵌入式node启动节点，启动后的节点不会加入到集群中？

2、使用 TransportClient 方式建立 Client，启动程序后，程序的控制台，和服务器端的es一直报错，获取节点信息失败，是什么原因？即上面的错误信息

下面是环境版本信息：

服务器端 es 版本：2.3.3

jdk 版本：1.7.0_79

spring-data-elasticsearch 版本：1.2.0.RELEASE(即：elasticsearch-1.4.4.jar)

服务器端 es 配置，elasticsearch.yml：

cluster.name: my-cluster

node.name: node-1

http 端口为：9200

节点间的通信端口为：9300

3、idk 版本过低，建议1.7+。已是1.7+

最后附上两种启动节点方式的完整代码

1、嵌入式 node 启动

import org.elasticsearch.client.Client;

import org.elasticsearch.node.Node;

import org.elasticsearch.node.NodeBuilder;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

@Configuration

@EnableElasticsearchRepositories(basePackages = "xx.xxx.domain.repository.elastic")

public class ElasticsearchConfiguration {

@Bean

public Client client() {

Node node = NodeBuilder.nodeBuilder().node();

node.start();

return node.client();

}

2、TransportClient 方式

import org.elasticsearch.client.Client;

import org.elasticsearch.client.transport.TransportClient;

import org.elasticsearch.common.settings.ImmutableSettings;

import org.elasticsearch.common.settings.Settings;

import org.elasticsearch.common.transport.InetSocketTransportAddress;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.data.elasticsearch.core.ElasticsearchOperations;

import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;

import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

@Configuration

@EnableElasticsearchRepositories(basePackages = "xx.xxx.domain.repository.elastic")

public class ElasticsearchConfiguration {

@Bean

public Client client() {

TransportClient client = new TransportClient();

client.addTransportAddress(new

InetSocketTransportAddress("127.0.0.1", 9300));

return client;

}

@Bean

public ElasticsearchOperations elasticsearchTemplate() {

return new ElasticsearchTemplate(client());

}
