java - Spring Boot 应用程序中的 Spring Data Elasticsearch

Question

我有一个 Spring Boot 应用程序，我想在其中使用独立的 Elastic search 2.2.0(不是嵌入式服务器)，我想使用 Spring Data Elastic search，那么 Spring Data 支持的 Elastic search 版本是什么以及如何实现我可以将它配置为连接到在 localhost:9200 中运行的 elasticsearch 实例吗？

实际上，我尝试将此选项添加到我的 application.properties 文件中:

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

后来，我创建了这个配置类:

@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;
    }
}

我得到这个堆栈跟踪:

Answer 1

我从 ES 论坛得到了这个答案，它对我有用:

首先，Spring Data Elasticsearch 正式适用于 ES 1.x 版本(对我来说它适用于 1.7.1)。二、配置中使用的端口必须是9300

我进行了这些更改并且效果非常完美。
