Java中的查询字符串操作

像这样

 public static Map<String, String> getQueryMap(String query)   {       String[] params = query.split("&");       Map<String, String> map = new HashMap<String, String>();       for (String param : params)       {String name = param.split("=")[0];String value = param.split("=")[1];map.put(name, value);       }       return map;   }

要简单地迭代地图：

 String query = url.getQuery();   Map<String, String> map = getQueryMap(query);   Set<String> keys = map.keySet();   for (String key : keys)   {      System.out.println("Name=" + key);      System.out.println("Value=" + map.get(key));   }
