Question

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，忽略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远程ES服务器？

Answer 1

我不知道您是否解决了连接问题，但站在Spring Data Elasticsearch Github project page的兼容性矩阵中，您不能。

(defun double2 (L) (cond ((atom L) nil) (t (setf (cdr L) (cons (car L ) (double2 (cdr L)))) L) ) ) (double2 (list 'a 'b 'c)) => (a a b b c c)

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2.4.6中的.m2存储库。

Answer 2

您不能将NodeBuilder与elasticsearch 6一起使用，请阅读this，使用节点（设置）并将spring boot版本升级到“2.0.1.RELEASE”等。
