Question

我正在使用Java HighLevelRestClient连接到我在AWS上托管的elasticsearch实例。我可以对邮递员和我的浏览器上的URL提出请求就好了，但是当我使用客户端库时，我会收到

java.net.ConnectException：拒绝连接。

（我目前不需要任何身份验证，因为这是一个小型公共测试实例）。这是我的代码：

RestHighLevelClient restHighLevelClient = new RestHighLevelClient(restClientBuilder);

GetRequest getRequest = new GetRequest("some_index", "some_type","some_id");
        final String[] elasticGetResponse = new String[1];

        restHighLevelClient.getAsync(getRequest, new ActionListener() {

            @Override
            public void onResponse(GetResponse documentFields) {
                try {
                    elasticGetResponse[0] = restHighLevelClient.get(getRequest).toString();
                }

                catch (IOException e) {
                    e.printStackTrace();
                }

            }

            @Override
            public void onFailure(Exception e) {
                e.printStackTrace();
            }
        });

请让我知道如何解决这个问题...谢谢！

更新：这是我的restClientBuilder的代码：

MySSLHelper sslHelper = new MySSLHelper(SSLConfig.builder()
                .withKeyStoreProvider(myKeyStoreProvider)
                .withTrustStoreProvider(InternalTrustStoreProvider.INSTANCE)
                .build());

        RestClientBuilder restClientBuilder = RestClient.builder(new HttpHost("MY_ELASTICSEARCH_ENDPOINT")).setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
            @Override
            public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpAsyncClientBuilder) {
                return httpAsyncClientBuilder.setSSLContext(sslHelper.getContext());
            }
        });

我遇到了同样的问题，并解决了端口和协议的放置问题，如本页所示： https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.0/java-rest-high-getting-started-initialization.html

我的代码保持这样：

RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(new HttpHost(elasticsearchHost, 9200, "http")));

请尝试执行以下操作：

RestClientBuilder restClientBuilder = RestClient.builder(new HttpHost("MY_ELASTICSEARCH_ENDPOINT", "MY_ELASTICSEARCH_PORT", "MY_ELASTICSEARCH_PROTOCOL"))...

希望这会有所帮助。
