spring3mvcportlet populate JSON dojo select

问题

I am new to Spring mvc3 portlet and dojo. I am trying to populate select dropdown with JSON data when jsp is loaded. I want to use dojo and give ajax call to controller and return JSON when jsp is loaded. Any tips will be helpful.

回答1:

@Controller
@RequestMapping("/yourController")
public class YourController
{
  @RequestMapping(value="/combo/{id}", method=ReqestNethod.GET)
  public String getDropDownData(@ParamValue("id") long id)
  {
    List<Combo> combos = commonDao.getCombos(id);
    String json = JsonUtil.toJson(combos); // or whichever way you use
    return json;
  }
}

Send requests from dojo to this url

<your-context-path>/yourController/combo/1

where 1 is your combo id.

I haven't checked the syntax here.. Wrote it blind. You might get compilation errors.
