Example below: HttpGet getMethod = new HttpGet( " HttpResponse response = httpClient.execute(getMethod) 4 – Usage of the HttpClientĪfter configuring the HttpClient, it is pretty straightforward to use it to make HTTP calls in your application. Therefore, in my view, this is the RECOMMENDED to configure HttpClient timeout properties in your application. This is a type-safe way to assigning the properties in a clean and error-free way. HttpClientBuilder.create().setDefaultRequestConfig(config).build() setSocketTimeout(timeout * 1000).build()
setConnectionRequestTimeout(timeout * 1000) RequestConfig config = RequestConfig.custom() See the below example for reference: int timeout = 5 With version 4.3, we have a much better way of setting the timeout properties. 3 – Configuring Java HTTPClient Timeout Properties (the New Way) The properties CoreConnectionPNames are part of the package. The timeout is provided in milliseconds and therefore, we multiple the value by 1000. Here, we have setup the three parameters in the HttpClient object. 2 – Configuring HTTPClient Timeout Timeouts (the Old Fashioned Way)īefore version 4.3, we had to use normal parameters using generic map to configure HttpClient. However, in high load scenarios, we also need to be careful about properly setting the third timeout as well.
In general, the first two parameters are the most important. This timeout deals with the time taken to receive an open connection from the pool.
#Java http client how to#
In this post, we will look at how to use configure Java HttpClient timeout properties. Therefore, it is imperative that we make appropriate use of Timeouts when designing HTTP calls in our applications. A user waiting for a response for an abnormally long time would be far more devastating to the business prospects of the application as compared to a failed response.
#Java http client software#
However, this is usually not the case in a typical software application. In real-life we may be tempted to wait for a long time for a response. So what should be a developer do in this case? However, just like in real life, a request is just a request and there is no guarantee a request would receive an appropriate response. HttpEntity entity = response.HTTP Request is a common integration approach used for building any reasonably sized application. HttpResponse response = client.execute(request) HttpClient client = HttpClientBuilder.create().build() Import .client.HttpClientBuilder Įntit圜ontentType demo = new Entit圜ontentType() To get the charset we can call the getCharset() method which will return a object. The HttpEntity can be obtained from the HttpResponse object.įrom the ContentType object we can get the mime-type by calling the getMimeType() method. The ContentType can be obtained by using ContentType.getOrDefault() method and passing an HttpEntity as the argument.

This code snippet show you how to get the content-type of an HTTP Get request.
