Retrieve timeout values from HttpComponentsClientHttpRequestFactory using spring ReflectionUtils

Question

I am using org.springframework.http.client.HttpComponentsClientHttpRequestFactory in my code and I want to use Reflection (org.springframework.util.ReflectionUtils) to retrieve some timeout values like ConnectTimeout from this object. I am not very clear on how to retrieve this field from this object.

I tried something like: ReflectionUtils.findField(httpComponentsClientHttpRequestFactory.getClass(), "connectTimeout");

But, the value is returned as null.

Answer 1

The timeout values are part of the RequestConfig field of HttpComponentsClientHttpRequestFactory. Following is the code to access the same.

HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
factory.setConnectTimeout(1000);

Field requestConfigField = ReflectionUtils.findField(
   HttpComponentsClientHttpRequestFactory.class, "requestConfig", RequestConfig.class);
requestConfigField.setAccessible(true);
RequestConfig requestConfig = (RequestConfig) ReflectionUtils.getField(requestConfigField, factory);

System.out.println("Connect timeoout = " + requestConfig.getConnectTimeout());
