过滤字符串

//因为Set为无序不重复
private static final Set SET = new HashSet();



static {
          SET.add("***.**");
         }
//利用iterator，也可以用Set.contain()方法;
 for (Iterator iter = SET.iterator(); iter.hasNext();) {
   String element = (String) iter.next();
   if(uri.indexOf(element) != -1){
    return true;
   }
  }
