我正在开发一个 Spring Boot 应用程序，它需要连接到远程 Elasticsearch 6.1 出于某种原因，当应用程序启动时，它默认为本地 ES 连接，而忽略了 settingsBuilder。

这是我的 ElasticConfiguration.java：

@Configuration
@EnableElasticsearchRepositories(basePackages = "com.techprimers.elastic.repository")
public class ElasticConfiguration {


    @Bean
    public NodeBuilder nodeBuilder() {
        return new NodeBuilder();
    }

    @Bean
    public ElasticsearchOperations elasticsearchTemplate() throws IOException {
        File tmpDir = File.createTempFile("elastic", Long.toString(System.nanoTime()));
        System.out.println("Temp directory: " + tmpDir.getAbsolutePath());
        Settings.Builder elasticsearchSettings =
                Settings.settingsBuilder()
                        .put("network.host","34.230.72.180")
                        .put("cluster.name", "my-es-cluster")
                        .put("http.enabled", "true") // 1
                        .put("index.number_of_shards", "1")
                        .put("path.data", new File(tmpDir, "data").getAbsolutePath()) // 2
                        .put("path.logs", new File(tmpDir, "logs").getAbsolutePath()) // 2
                        .put("path.work", new File(tmpDir, "work").getAbsolutePath()) // 2
                        .put("path.home", tmpDir); // 3



        return new ElasticsearchTemplate(nodeBuilder()
                .local(false)
                .settings(elasticsearchSettings.build())
                .node()
                .client());
    }
}

这是我的pom：

如何强制应用连接到我的远程 ES 服务器？

我不知道你是否解决了你的连接问题，但是站在Spring Data Elasticsearch Github 项目页面中的兼容性矩阵上，你不能。

| spring data elasticsearch | elasticsearch | |:-----------------------------------:|:-------------:| | 3.0.0.RC2 | 5.5.0 | | 3.0.0.M4 | 5.4.0 | | 2.0.4.RELEASE | 2.4.0 | | 2.0.0.RELEASE | 2.2.0 | | 1.4.0.M1 | 1.7.3 | | 1.3.0.RELEASE | 1.5.2 | | 1.2.0.RELEASE | 1.4.4 | | 1.1.0.RELEASE | 1.3.2 | | 1.0.0.RELEASE | 1.1.1 |

该页面已过时。但是，我刚刚下载了 Spring Data Elasticsearch 的 2.1.9 版本，而我拥有的 Elasticsearch jar 是我在 2.4.6 中的 .m2 存储库。

您不能将 NodeBuilder 与 elasticsearch 6 一起使用，请阅读此内容，使用 Node(Settings) 并将 Spring Boot 版本升级到“2.0.1.RELEASE”等。
