Java – Apache HTTP client prints “[read] I / O error: read timeout”“

I am using Apache HTTP client v4 5 and use it as a rest client In some cases, I recognize an error "[read] I / O error: read timeout", which comes from the httpclient framework when it reads the received content and displays it as the last message

It doesn't seem to matter, but I wonder if anyone knows where it comes from and how to solve it According to the following topics, it seems that there is a problem with the "mutlithreaded" configuration

But I only use the default configuration of the HTTP client. When I use version V4, I don't know how to set "multithreaded" to false to see if it makes any difference

I also tried to set the timeout, but it didn't help

Any tips?

My HTTP client initialization

HttpClientBuilder httpBuilder = HttpClientBuilder.create();

//      set timeout did not helped
//      RequestConfig.Builder requestBuilder = RequestConfig.custom();
//      requestBuilder = requestBuilder.setConnectTimeout(timeout);
//      requestBuilder = requestBuilder.setConnectionRequestTimeout(timeout);
//      requestBuilder = requestBuilder.setSocketTimeout(timeout);
//      httpBuilder.setDefaultRequestConfig(requestBuilder.build());

HttpClient httpClient = httpBuilder.build();

Solution

I'm using httpclient 4.5 2. In my case, setting the timeout on request helps:

HttpPost postRequest = new HttpPost("https://...");
postRequest.setHeader(...,...);

RequestConfig requestConfig = RequestConfig.custom()
                        .setSocketTimeout(1000)
                        .setConnectTimeout(1000)
                        .build();

postRequest.setConfig(requestConfig);
