req.getParameterMap();得到一个Map,再循环取出map中的元素.

Answer 3

Map m = req.getParameterMap();
  Iterator it = m.entrySet().iterator();
        while (it.hasNext())
        {
            Map.Entry entry = (Map.Entry) it.next();
            System.out.print(entry.getValue());
            System.out.print(entry.getKey());         }

for (Iterator iterator = request.getParameterMap().entrySet().iterator(); iterator.hasNext();) {
  Map.Entry entry= (Map.Entry)iterator.next();
  System.out.println(entry.getKey()+":"+entry.getValue());
}
