Der Typ DefaultHttpClient ist veraltet
Eclipse IDE fordert beinew DefaultHttpClient zur Warnung auf. Markieren Sie diese Klasse als veraltet.
package com.example.web.controller;
import org.apache.http.Header;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
public class WebCrawler {
public static void main(String[] args) throws Exception {
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet("/");
HttpResponse response = client.execute(request);
//...
}
}
Lösung
Tauchen Sie in den Quellcode ein, siehe diese Kommentare:
DefaultHttpClient.java
* @deprecated (4.3) use {@link HttpClientBuilder}.
*/
@ThreadSafe
@Deprecated
public class DefaultHttpClient extends AbstractHttpClient {
//...
Verwenden Sie zur LösungHttpClientBuilder:
package com.hostingcompass.web.controller;
import org.apache.http.Header;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClientBuilder;
public class WebCrawler {
public static void main(String[] args) throws Exception {
HttpClient client = HttpClientBuilder.create().build();
HttpGet request = new HttpGet("/");
HttpResponse response = client.execute(request);
//...
}
}
