spring - 无法将自定义自动配置与 spring-data-elasticsearch 一起使用

Question

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

关于使用以下 POM

        </resources>

    </build>
</project>

并添加自定义 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());
    }
}

Application.java

下有以下内容

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

我仍然收到 elasticsearch 1.5.2(以及额外的 2.0.1.RELEASE 版本)作为我有效 POM 中的依赖项。

在运行应用程序时收到以下错误。

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

Answer 1

问题是 spring-boot 1.3.2.RELEASE 还不能与 spring-data-elasticsearch 2.0.0-RELEASE 一起使用。

spring-boot 1.3.2 将包括 spring-boot-starter-data-elasticsearch 1.3.2-RELEASE 仍然是 depends on elasticsearch 1.5.2

ES 2.0 将在 spring-boot 1.4.0-RELEASE 中得到支持，该版本尚未发布(但您可以尝试使用 1.4.0.BUILD-SNAPSHOT 看看是否有帮助)

由于您还明确包含 spring-data-elasticsearch 2.0.0-RELEASE，因此您获得了包含 2.0 版本的 elasticsearch，但您应该删除该依赖项，因为它由 spring-boot 管理-starters 本身
