问题内容：

我无法让spring-data-elasticsearch适用于Elasticsearch 2.0+版本。

关于使用以下POM

并添加自定义的ElasticsearchConfiguration

package com.package.project.module.application;

import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.common.transport.TransportAddress;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.context.annotation.PropertySources;
import org.springframework.core.env.Environment;
import org.springframework.data.elasticsearch.core.ElasticsearchOperations;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

import java.net.InetSocketAddress;

import javax.annotation.Resource;

@Configuration
@PropertySources({
        @PropertySource(value = "classpath:elasticsearch.properties", ignoreResourceNotFound = true),
        @PropertySource(value = "classpath:app.properties", ignoreResourceNotFound = true) })
@EnableElasticsearchRepositories(basePackages = "com.package.project.module.repository")
public class ElasticsearchConfiguration {
    @Resource
    private Environment environment;

    @Bean
    public Client client() {
        Settings settings = Settings.settingsBuilder().put("cluster.name", environment.getProperty("cluster.name")).build();
        Client client = TransportClient.builder().settings(settings).build();
        String[] addresses = environment.getProperty("cluster.nodes").split(",");
        for (int i = 0; i < addresses.length; i++) {
            System.out.println(addresses[i].trim());
            TransportAddress address = new InetSocketTransportAddress(new InetSocketAddress(addresses[i].trim(), Integer.parseInt(environment.getProperty("elasticsearch.port"))));
            ((TransportClient) client).addTransportAddress(address);
        }
        return client;
    }

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

在 Application.java* 下面 *

@Configuration
@ComponentScan(basePackages = "com.package.project.module")
@EnableAutoConfiguration(exclude = {ElasticsearchConfiguration.class})
public class Application extends SpringBootServletInitializer {

在有效的POM中，我仍然收到elasticsearch 1.5.2（以及附加的2.0.1.RELEASE版本）作为依赖项。

在运行应用程序时收到以下错误。

我正在按照spring-data-elasticsearch github repo和docs中提到的说明进行操作。

问题答案：

问题是spring-boot1.3.2.RELEASE尚未与spring-data-elasticsearch2.0.0-RELEASE一起使用。

spring-boot1.3.2将包含spring-boot-starter-data- elasticsearch1.3.2-RELEASE，该版本仍取决于elasticsearch
1.5.2

从spring-boot1.4.0-RELEASE版本开始支持ES 2.0 （尚未发布）（但您可以尝试使用1.4.0.BUILD-
SNAPSHOT来查看是否有帮助）

由于您还明确包含spring-data- elasticsearch2.0.0-RELEASE，因此获得了包含2.0版的elasticsearch，但是您应删除该依赖项，因为它是由其spring- boot-starters自己管理的
