spring boot3整合Elasticsearch 实现快速入门

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.elasticsearch.client.ClientConfiguration;
import org.springframework.data.elasticsearch.client.RestClients;
import org.springframework.data.elasticsearch.config.AbstractElasticsearchConfiguration;
 
@SpringBootApplication
public class ElasticsearchApplication extends AbstractElasticsearchConfiguration {
 
    @Override
    public RestHighLevelClient elasticsearchClient() {
        final ClientConfiguration clientConfiguration = ClientConfiguration.builder()
                .connectedTo("localhost:9200") // 替换为你的Elasticsearch节点地址
                .build();
        return RestClients.create(clientConfiguration).rest();
    }
 
    public static void main(String[] args) {
        SpringApplication.run(ElasticsearchApplication.class, args);
    }
}

这段代码展示了如何在Spring Boot 3应用程序中整合Elasticsearch，并创建一个RestHighLevelClient实例用于连接到Elasticsearch服务。注意替换localhost:9200为你的Elasticsearch节点地址。
