一个简单的拆分URL的小程序

package com.test;
public class SplitUrl {  
 
     public static void main(String[] args) {  
         read("http://localhost:8888/esb/server");
     }  
 
     /**
      * 拆分URL
      * @param url
      */
     public static void read(String url){  
         //String url="http://www.baidu.com:8080/index.jsp";  
         //String url2="ftp://baidu.com/pub/index.jsp";  
         int firSplit=url.indexOf("//");  
         String proto=url.substring(0, firSplit+2);  
         int webSplit=url.indexOf("/", firSplit+2);  
         int portIndex=url.indexOf(":",firSplit);  
         String webUrl=url.substring(firSplit+2, webSplit);  
         String port= "";  
         if(portIndex >= 0){  
             webUrl=webUrl.substring(0, webUrl.indexOf(":"));  
             port=url.substring(portIndex+1, webSplit);  
             System.out.println("端口："+port);  
         }  
         String context=url.substring(webSplit);  
         System.out.println("协议:"+proto);  
         System.out.println("网址："+webUrl);  
         System.out.println("内容："+context);  
     }  
 
 }
