DOM4J遇到回车换行报错解决方法

按字节读取输入流并替换回车换行符，经测试windows和Linux通用

 

 in = req.getInputStream();// 取返回值
     StringBuffer buffer = new StringBuffer();
     int i = 0;
     while (i != -1) {
      i = in.read();
      if (i != -1) {
       buffer.append((char) i);
      }
     }
     String xmlresult = new String(buffer.toString()
       .getBytes("iso-8859-1"), "utf-8");
         xmlresult=xmlresult.replaceAll("\r", "").replaceAll("\n", "");
