java - 使用 Java API 的 Elasticsearch 负载均衡器 url

问题描述

我们正在使用 Java Rest 高级客户端来调用 elasticsearch 节点。

现在我们添加了一个负载均衡器并启用了 SSL。我们无法使用 Rest 客户端访问负载均衡器 URL。它会引发错误并且无法找到任何解决方案，例如如何通过 Java API 调用负载均衡器 URL。

有人可以帮忙吗？

代码：

        RestHighLevelClient client = new RestHighLevelClient(
            RestClient.builder(new HttpHost("hostname")));
    SearchRequest searchRequest = new SearchRequest("testCollection");
    SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
    sourceBuilder.query(QueryBuilders.queryStringQuery("test"));
    searchRequest.source(sourceBuilder);
    try {
        SearchResponse searchResponse=client.search(searchRequest);
        String response = searchResponse.toString();
        System.out.println("search response :"+ response);
    }
    catch (IOException e ) {
        e.printStackTrace();
    }
    finally {
        try {
            client.close();
        } catch (IOException e) {
            System.out.println("error while closing");
            e.printStackTrace();
        }
    }

错误：
