在 apache http 客户端中设置超时
2022-09-01 17:44:11
我正在使用Apache http客户端4.3.2发送get请求。我所做的是:
private final RequestConfig requestConfig = RequestConfig.custom()
.setConnectTimeout(1000)
.setConnectionRequestTimeout(1000)
.setSocketTimeout(1000)
.build();
private final HttpClient client = HttpClientBuilder.create()
.disableAuthCaching()
.disableAutomaticRetries()
.disableConnectionState()
.disableContentCompression()
.disableCookieManagement()
.disableRedirectHandling()
.setDefaultRequestConfig(requestConfig)
.build();
发送请求时:
HttpGet request = null;
try {
request = new HttpGet(url);
if (client.execute(request).getStatusLine().getStatusCode() == 200) {
/* do some work here */
}
} catch (Exception e) {
Logger.error(e);
} finally {
if (request != null) {
request.releaseConnection();
}
}
但是我的一些请求仍然需要很长时间才能超时。这是异常的堆栈跟踪:

是否还有其他应设置的超时值?我做错了什么?
