import java.io.IOException; 
import java.io.InputStream;
import java.net.HttpURLConnection; 
import java.net.URL; 
public class JavaHttpURLConnectionsetFollowRedirectsExample1 {
    //Starting the main method...
    public static void main(String h[]) throws IOException 
	{ 
        //starting the try block
        try {
        String link_url ;
        link_url="https://tpointtech.cn";
        URL obj1 = new URL(link_url); //URL Connection Created...
        HttpURLConnection con1 = (HttpURLConnection) obj1.openConnection(); //Http URL Connection Created...
        con1.connect();
         HttpURLConnection.setFollowRedirects(true);
            System.out.println("getFollowRedirects : "+con1.getFollowRedirects());
        con1.setConnectTimeout(1000);
        con1.disconnect();
        System.out.println("connecion disconnected");
        }
        catch (Exception e) {
            System.out.println( e);
        }
}
}

输出

getFollowRedirects : true
connecion disconnected

public class JavaHttpURLConnectionsetFollowRedirectsExample2 {
    //Starting the main method...
    public static void main(String h[]) throws IOException

        //starting the try block
        try {
         String link_url1, link_url2;
        link_url1="https://mysqlserver.cn";
        link_url2="https://www.oracle.com";
        URL obj1 = new URL(link_url1); //URL Connection Created...
        URL obj2 = new URL(link_url2);
        HttpURLConnection con1 = (HttpURLConnection) obj1.openConnection(); //Http URL Connection Created...
        HttpURLConnection con2 = (HttpURLConnection) obj2.openConnection();
        con1.connect();
         HttpURLConnection.setFollowRedirects(true);
        System.out.println("www.mysql.com");
        System.out.println("getFollowRedirects :" + con1.getFollowRedirects());
        System.out.println("www.oracle.com");
        System.out.println("getFollowRedirects :" + con2.getFollowRedirects());
        con1.setConnectTimeout(1000);
        con1.disconnect();
        System.out.println("connection disconnected");
        }
        catch (Exception e) {
            System.out.println( e);
        }
}
