Java use Jsoup to connect Web site timeout Solution _java

Today I did a jsoup to resolve the Web site, using the Jsoup.connect (URL). Get () occasionally occurs when you connect to a Web site
Java.net.SocketTimeoutException:Read timed out exception.
The reason is that the default socket delay is relatively short, and some Web sites are slower response speed,
So the timeout situation occurs.

Workaround :

Set the timeout time when linking.
doc = jsoup.connect (URL). Timeout (5000). get ();
5000 indicates that the delay time is set to 5s.

The test code is as follows:
1, do not set timeout:

Copy Code code as follows:

Package jsouptest;

Import java.io.IOException;

Import org.jsoup.*;
Import Org.jsoup.helper.Validate;
Import org.jsoup.nodes.Document;
Import org.jsoup.nodes.Element;
Import org.jsoup.select.Elements;

public class Jsouptest {
public static void Main (string[] args) throws ioexception{
String url = "Http://www.jb51.net";
Long start = System.currenttimemillis ();
Document Doc=null;
try{
doc = jsoup.connect (URL). get ();
}
catch (Exception e) {
E.printstacktrace ();
}
finally{
System.out.println ("Time is:" + (System.currenttimemillis ()-start) + "MS");
}
Elements Elem = Doc.getelementsbytag ("Title");
System.out.println ("Title is:" +elem.text ());
}
}

Sometimes timeouts occur:

2 is set, it usually doesn't timeout.

Copy Code code as follows:

Package jsouptest;

Import java.io.IOException;

Import org.jsoup.*;
Import Org.jsoup.helper.Validate;
Import org.jsoup.nodes.Document;
Import org.jsoup.nodes.Element;
Import org.jsoup.select.Elements;

public class Jsouptest {
public static void Main (string[] args) throws ioexception{
String url = "Http://www.jb51.net";
Long start = System.currenttimemillis ();
Document Doc=null;
try{
doc = jsoup.connect (URL). Timeout (5000). get ();
}
catch (Exception e) {
E.printstacktrace ();
}
finally{
System.out.println ("Time is:" + (System.currenttimemillis ()-start) + "MS");
}
Elements Elem = Doc.getelementsbytag ("Title");
System.out.println ("Title is:" +elem.text ());
}
}
