为什么这个Spring Boot应用程序仅加载嵌入式Elasticsearch实例？

Question

我正在玩spring-boot-sample-data-elastcisearch项目。

该应用程序有效，但仅适用于嵌入式Elasticsearch。

我希望它与我的本地elasticsearch实例一起运行。 为什么Embed ElasticSearch在此应用程序中运行？

import org.elasticsearch.client.Client;
import org.elasticsearch.node.NodeBuilder;

import java.io.IOException;

import static org.elasticsearch.common.xcontent.XContentFactory.jsonBuilder;
import static org.elasticsearch.node.NodeBuilder.nodeBuilder;


public class ElasticHelper {

    /**
     * Spin up an elasticsearch node in the background
     */
    public static Client startCluster() {
        NodeBuilder nb = nodeBuilder()
                .local(true)
                .clusterName("autocomplete");

        nb.settings()
                .put("index.number_of_shards", "1")
                .put("index.number_of_replicas", "0")
                .put("path.home", "target/elasticsearch")

                .put("path.logs", "target/elasticsearch/logs")
                .put("path.work", "target/elasticsearch/work");

        return nb.node().client();
    }
