Whether the Java test URL address can be properly connected

public static int testwsdlconnection (String address) throws Exception {
  int status = 404;
  try {
   url urlobj = new URL (address);
   HttpURLConnection OC = (httpurlconnection) urlobj.openconnection ();
   Oc.setusecaches (false);
   Oc.setconnecttimeout (3000); Set timeout
   status = Oc.getresponsecode ()//Request state
   if (= = = status) {
    //200 is the request address smoothly connected. return
    status;
   }
  catch (Exception e) {
   e.printstacktrace ();
   throw e;
  }
  return status;
 }

An int is defined, and if 200 is returned, the address can be communicated successfully, if 0 is returned or otherwise it fails.

Let's look at a section of code that is available or open to Java detection URLs.

Package test;
Import java.net.HttpURLConnection;
Import Java.net.URL;
Import Org.apache.log4j.Logger;
public class Cheskurl {
  private static Logger Logger = Logger.getlogger (cheskurl.class);
  private static URL urlstr;
  private static httpurlconnection connection;
  private static int state =-1;
  private static String succ;
  Public synchronized string isconnect (string url) {
   int counts = 0;
   SUCC = null;
   if (url = null | | url.length () <= 0) {return
    succ;
   }
   while (counts < 5) {
    try {
     urlstr = new URL (URL);
     Connection = (httpurlconnection) urlstr.openconnection ();
     State = Connection.getresponsecode ();
     if (state = =) {
      succ = Connection.geturl (). toString ();
     break;
    catch (Exception ex) {
     counts++; Logger.info ("Loop:" + counts);
     Continue
    }
   }
   return SUCC
  }
}
