//超时设置
RequestConfig requestConfig = RequestConfig.custom()
.setConnectTimeout(400).setSocketTimeout(400).build();
request.setEntity(s);
request.setConfig(requestConfig);
HttpClient client = new HttpClient();
HttpResponse httpResponse = client.execute(request);
发现设置并未生效，后发现是由于没有设置重试选项，将代码修改如下：
private HttpRequestRetryHandler myRetryHandler = new HttpRequestRetryHandler() {
@Override
public boolean retryRequest(IOException exception,
int executionCount, HttpContext context) {
return false;
}};
//超时设置
RequestConfig requestConfig = RequestConfig.custom()
.setConnectTimeout(connectTImeoutInMills).setSocketTimeout(socketTImeoutInMills).build();
request.setEntity(s);
request.setConfig(requestConfig);
HttpClient client = HttpClients.custom().setRetryHandler(myRetryHandler).build();
HttpResponse httpResponse = client.execute(request);
