Why I am getting DefaultHttpClient is deprecated?
I am working on a project in which I need to make a call to my service and my service will return the data back in JSON format. And I don't need to serialize this JSON response to any POJO, I just need to get the data back as String. And this application is very performance critical so HttpClient has to be pretty fast
So I decided to use Apache HttpClient or is there any better alternative which I can use?
But it complains that The type DefaultHttpClient is deprecated so maybe they have new version of HttpClient or some other way of making a HttpClient call to an URL?
Is there anything I am missing?
Use this:
Refer to this stackoverflow post
From Apache HTTP Client API version 4.3 on wards, DefaultHttpClient is deprecated.
Use following maven dependency as an example.
Following import.
Following code block.

DefaultHttpClient httpclient = new DefaultHttpClient();
HttpUriRequest request = new HttpGet("some-url");
request.addHeader("Context", "some-value");
HttpResponse response = httpClient.execute(request);
String response = IOUtils.toString(response.getEntity().getContent(), "UTF-8");But it complains that The type DefaultHttpClient is deprecated so maybe they have new version of HttpClient or some other way of making a HttpClient call to an URL?

Use this:
HttpClient httpclient = HttpClientBuilder.create().build();
