java 中如何给http 设置超时请求

Question

java 中网络发送的请求超时如何设置？

ConnManagerParams.setTimeout(params, 1000);

我查到的这个方法已经被废弃了，我的代码

headers.add(new BasicHeader("User-Agent", "Mozilla/5.0(Windows NT 6.1;Win64; x64; rv:50.0) Gecko/20100101 Firefox/50.0"));
headers.add(new BasicHeader("Referer", "https://gongshang.mingluji.com/beijing/"));
HttpClientBuilder httpClient = HttpClientBuilder.create().setDefaultHeaders(headers);
HttpGet httpGet = new HttpGet(url);
CloseableHttpResponse response = httpClient.build().execute(httpGet);
TimeUnit.SECONDS.sleep(SleepTime);
HttpEntity httpEntity = response.getEntity();
ResponseBody = EntityUtils.toString(httpEntity, "utf-8");

Answer 1

如果是使用apache的httpclient发送http请求，请求的超时时间是通过socket设置的，可参考如下代码：

 CloseableHttpClient client = HttpClients.custom()
            .setDefaultRequestConfig(RequestConfig.custom()
                    .setConnectTimeout(500) //连接超时时间，单位毫秒，按实际情况调整
                    .build())
            .setDefaultSocketConfig(SocketConfig.custom()
                    .setSoTimeout(2 * 1000) //请求响应超时时间，单位毫秒，这里设为2秒，按实际情况调整
                    .build())
            .build();

Answer 2

RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(500000).setConnectionRequestTimeout(100000).setSocketTimeout(500000).build();
httpGet.setConfig(requestConfig);
