java讀取xml

1、這是我定義的xml，test.xml

<PathDefines>
 <PathDefine name="***" paperType="P">
  <printType name="test1"  url="/paper-print.jsp" printModeId="1"></printType>
  <printType name="test2"  url="/paper-print0.jsp" printModeId="2"></printType>
 </PathDefine>

</PathDefines>

2、為了擷取xml中的url，寫的類如下:

public class Test{
 
 public Test(){
  
 }
 
 /**
  * 根據傳入的參數，找到對應的url並返回
  * @param paperType單據類型
  * @param parameterId 列印型別參數
  * return  返回當前路徑
  */
 public String getPageUrl(String paperType,String printModeId){
  
  try{
   ClassLoader cl=Thread.currentThread().getContextClassLoader();
   SAXReader reader=new SAXReader();
   Document document=reader.read(cl.getResourceAsStream("test.xml"));
   Iterator iter=document.selectNodes("/PathDefines/PathDefine[@paperType='"+paperType+"']/printType[@printModeId='"+printModeId+"']").iterator();
   String result="";
   if (iter.hasNext())
    result=((Element)iter.next()).attributeValue("url");
   return result;
  }catch(Exception e){
   System.out.println(e);
   e.printStackTrace();
   return "";
  }

public static void main(String[] args){
  PrintPath printPath=new PrintPath();
  String url=printPath.getPageUrl("P", "1");
  System.out.println(url);
 }

 }
