Spring Data Elastic search in a Spring Boot application

I have a Spring Boot application and I want to use Elastic search 2.2.0 standalone (not the embedded server) in it, I wanna use Spring Data Elastic search, so what are the Elastic search supported versions by Spring Data and how can I configure it to connect to elasticsearch instance running in localhost:9200?

Actually, I tried adding this options to my application.properties file:

spring.data.elasticsearch.repositories.enabled=true
spring.data.elasticsearch.cluster-nodes=localhost:9200

And later, I created this configuration class:

@Configuration
public class ElasticConfig {

    @Bean
    public ElasticsearchOperations elasticsearchTemplate() {
        return new ElasticsearchTemplate(client());
    }

    @Bean
    public Client client() {
        TransportClient client = new TransportClient();
        TransportAddress address = new InetSocketTransportAddress(
                "localhost",9200);
        client.addTransportAddress(address);
        return client;
    }
}

I get this stacktrace:

It's only a client. Please check your elasticsearch server status. – Gemini Keith
@Gemini Keith: elasticsearch is up and running: localhost:9200 { "name" : "Hildegarde", "cluster_name" : "elasticsearch", "version" : { "number" : "2.2.0", "build_hash" : "8ff36d139e16f8720f2947ef62c8167a888992fe", "build_timestamp" : "2016-01-27T13:32:39Z", "build_snapshot" : false, "lucene_version" : "5.4.1" }, "tagline" : "You Know, for Search" } – jemlifathi
See this answer: stackoverflow.com/a/36858819/4604579 . Spring Data is not yet ready for ES 2.x – Val

I got this answer from the ES forum and it worked for me:

First, Spring Data Elasticsearch works officially with ES 1.x versions(for me it worked with 1.7.1). Second, the port used in the configuration must be 9300

I made these changes and it worked pretty perfect.

As Jemli said you will need to use the port 9300.

Also make sure that your elastiscsearch client and server are using the same major version. If you are using elasticsearch 2.x you will need to update spring boot to the latest version ( > 1.4.0.RC1).

Please have a look to this post if you need more information: http://ignaciosuay.com/how-to-connect-spring-boot-to-elasticsearch-2-x-x/

I read official document. If use Java Config,please try:

@Configuration
@EnableElasticsearchRepositories(basePackages = "org/springframework/data/elasticsearch/repositories")
static class Config {

@Bean
public ElasticsearchOperations elasticsearchTemplate() {
    return new ElasticsearchTemplate(nodeBuilder().local(true).node().client());
}
}

If use XML， please try:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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-3.1.xsd
http://www.springframework.org/schema/data/elasticsearch
http://www.springframework.org/schema/data/elasticsearch/spring-elasticsearch-1.0.xsd">

<elasticsearch:transport-client id="client" cluster-nodes="localhost:9300,someip:9300" />

</beans>
