Java 测试URL地址是否能正常连接的代码

java 测试url地址是否能正常连接

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); // 设置超时时间
   status = oc.getresponsecode();// 请求状态
   if (200 == status) {
    // 200是请求地址顺利连通。。
    return status;
   }
  } catch (exception e) {
   e.printstacktrace();
   throw e;
  }
  return status;
 }

定义了一个int型，如果返回可200则是地址能成功连通，如果返回0或者其他则是失败。

下面再看一段关于java检测url是否可用或者可打开的代码

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 == 200) {
      succ = connection.geturl().tostring();
     }
     break;
    } catch (exception ex) {
     counts++; logger.info("loop :" + counts);
     continue;
    }
   }
   return succ;
  }
}
