使用RestHighLevelClient调用搜索模板URI

Question

我们正在尝试从ElasticSearchDB查询，伪代码如下所示。

public String searchMovieRelease(){ 
String movieRelease=null;
WebTarget   webTarget = target.path("_search/template");     (1)
Invocation.Builder builder = getInvokationBuilder(target);       (2)
movieRelease = builder.post(Entity.json(query));                 (3)
return movieRelease;
}

1. 获取指向所需URI的目标。
2. 获取构建
3. 通过构建器发布请求查询，并从弹性搜索中获得响应。

现在，我如何使用RestHighLevelClient实现相同的功能。

Answer 1

你可以这样做:

var client = new RestHighLevelClient(RestClient.builder(HttpHost.create("host"))
.setRequestConfigCallback(requestConfigBuilder -> requestConfigBuilder.setConnectTimeout(60000).setSocketTimeout(60000)));
var lowClient = client.getLowLevelClient();
var request = new Request("GET", "endpoint");
var response = lowClient.performRequest(request);
