I am actually using Spring 3 MVC and listing data with pagination using PagedListHolder passing the method from my service layer to get all rows from a DB table like this:
PagedListHolder myList = new PagedListHolder(myService.getAll());
And this is my controller code:
public class MyListController implements Controller {
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
String page = request.getParameter("page");
MyService myService = new MyService();
PagedListHolder myList = new PagedListHolder(myService.getAll());
myList.setPageSize(5);
if ("next".equals(page)) {
myList.nextPage();
}
else if ("previous".equals(page)) {
myList.previousPage();
}
ModelAndView modelAndView = new ModelAndView("myList");
modelAndView.addObject("myList", myList.getPageList());
return modelAndView;
}
}
So, this is working perfect but I want to make now a search from myListby using a keyword and the normal way I think could be implementing a method in DAO and Service layers like for example:
...
String keyword = request.getParameter("keyword");
PagedListHolder myList = new PagedListHolder(myService.findByWord(keyword));
...
At this point myList will return all rows from DB that matches my keyword.
What I want to know is if there is a way to search from myList (using myService.getAll(); method and maybe some other method from PagedListHolder) and avoid modifying the DAO and Service layers for not creating extra methods like the one I used in the example above.
Thanks in advance.
