struts 2 javaページング

2回目にページングコードを変更し、いくつかの小さなバグを解決しました.このコードはまだテスト中です.問題の指摘を歓迎します.の
AJAXページングを使用していない場合は、jspページのハイパーリンクのjsをactionリクエストアドレスに置き換えます.
これはajaxPageInfo.javaです

import org.apache.struts2.ServletActionContext;

		Iterator iter = m.entrySet().iterator();

		Map.Entry entry = (Map.Entry) iter.next(); 
		  if(!entry.getKey().equals("cur_arg")){
			Object key = entry.getKey();

			queryString+="&"+key+"="+val;
		  }
