对web的request的全部值进行了提取

protected ParmModel getParmModel(HttpServletRequest request) {
ParmModel parmModel = new ParmModel();
Enumeration<?> enumh = request.getParameterNames();
while (enumh.hasMoreElements()) {
String key = (String) enumh.nextElement();
if (!key.equals("page") && !key.equals("rows")
&& !key.equals("order") && !key.equals("sort")) {
if (request.getParameterValues(key).length > 1) {
parmModel.put(key, request.getParameterValues(key));
} else {
parmModel.put(key, request.getParameter(key));
}
}
}
return parmModel;
}
