如何开玩笑地传递多个节点地址（Elasticsearch）

Question

我是 JEST 技术的新手。我正在通过https://github.com/searchbox-io/Jest/tree/master/jest#authentication 链接练习它。我能够创建索引并向其添加文档，但我想传递多个节点。

这是我的代码

JestClientFactory factory = new JestClientFactory();

factory.setHttpClientConfig(new HttpClientConfig 
        .Builder("http://192.167.1.2:9200") 
        .defaultCredentials("user", "password")
        .multiThreaded(false) 
        //Per default this implementation will create no more than 2 concurrent connections per given route 
        .defaultMaxTotalConnectionPerRoute(2) // and no more 20 connections in total 
        .maxTotalConnection(5) 
        .build());

JestClient client = factory.getObject();

我有 3 个节点的集群，所以我想在代码中传递 3 个节点。任何帮助将不胜感激。

谢谢

其实就像link you gave里写的，可以给Builder传一个list，见：

JestClientFactory factory = new JestClientFactory();
factory.setHttpClientConfig(
    new HttpClientConfig.Builder(Arrays.asList("http://192.168.0.88:9200", "http://192.168.0.172:9200"))
        .credentialsProvider(customCredentialsProvider)
        .build()
);

实际上更准确地说，Builder 接受Collection<String>，见：https://github.com/searchbox-io/Jest/blob/master/jest/src/main/java/io/searchbox/client/config/HttpClientConfig.java#L127
