All I'm trying to do is download some JSON and deserialize it into an object. I haven't got as far as downloading the JSON yet.
Almost every single HttpClient example I can find, including those on the apache site looks something like...
import org.apache.http.client.HttpClient;
import org.apache.http.impl.client.DefaultHttpClient;
public void blah() {
HttpClient client = new DefaultHttpClient();
...
}
However, Netbeans tells me that DefaultHttpClient
is deprecated. I've tried googling for DefaultHttpClient deprecated
and as many other variations as I can think of and can't find any useful results, so I'm obviously missing something.
What is the correct Java7 way to download the contents of a webpage? Is there really no decent Http Client as part of the language? I find that hard to believe.
My Maven dependency for this is...
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>LATEST</version>
<type>jar</type>
</dependency>
Relevant imports:
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import java.io.IOException;
Usage:
HttpClient httpClient = HttpClientBuilder.create().build();
EDIT (after Jules' suggestion):
As the build()
method returns a CloseableHttpClient
which is-a AutoClosable
, you can place the declaration in a try-with-resources statement (Java 7+):
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
// use httpClient (no need to close it explicitly)
} catch (IOException e) {
// handle
}
