Spring framework usage for JSP

Тусгай тэмдэгтийн тайлбар: <any> нь any бол заавал бичигдэх ёстой зүйлийг заана.

1. WebLayoutController

public class <Name>Controller extends WebLayoutController {

/**

*for <td>${<contextname>_}</td>

*/

private static final String DEFAULT_CONTENT_OBJECT_PREFIX = "<contextname>_";

/**

*List list = manager.list(id, site);

*request.setAttribute(prefix+“list”, list);

*/

private <Name>Manager manager;

/**

*for <td>${<prefix>list}</td>

*/

private String prefix = DEFAULT_CONTENT_OBJECT_PREFIX;

@Override

protected ModelAndView handleSiteRequest(HttpServletRequest request

, HttpServletResponse httpServletResponse

, ModelAndView modelAndView

, PageInfo pageInfo, WebSite webSite) throws Exception {

Object clientId = request.getSession()

.getAttribute(webSite.getConfiguration(Config.SESSION_CLIENT_ID));

String clientStatus = request.getParameter(“firstname”);

if (clientId == null || !clientStatus.equals(“in”)) {

//response any jump url

response.setHeader("Cache-Control","no-cache"); //HTTP 1.1

  response.setHeader("Pragma","no-cache"); //HTTP 1.0
  response.setDateHeader ("Expires", 0); //prevents caching at the proxy server

response.sendRedirect(request.getContextPath()

+ "/<key of Controller>(home.shtml .etc)");

return null;

} else {

//response any content page with layout page

modelAndView.addObject(CONTENT_JSP_KEY, <contentPageName> + ".jsp");

}

return modelAndView;

}

2. AbstractController

public class ClientXdataController extends AbstractController {

/**

*for <td>${<contextname>_}</td>

*/

private static final String DEFAULT_CONTENT_OBJECT_PREFIX = "<contextname>_";

/**

*List list = manager.list(id, site);

*request.setAttribute(prefix+”list”, list);

*/

private <Name>Manager manager;

/**

*for <td>${<prefix>list}</td>

*/

private String prefix = DEFAULT_CONTENT_OBJECT_PREFIX;

@Override

protected ModelAndView handleRequestInternal(HttpServletRequest request

, HttpServletResponse response) throws Exception {

WebSite webSite = WebUtil.getSiteFromRequest(httpServletRequest);

Object client = request.getSession()

.getAttribute(webSite.getConfiguration(Config.SESSION_CLIENT_ID));

if (client == null && “”.equals(client)) {

//response any content page

ModelAndView next = new ModelAndView(

webSite.getName()+"/"+webSite.getTemplate()

+"/<title of Controller>(home .etc)");

return next;

} else {

//response any text

response.getWriter().println("OK");

return null;

}

}

}

Sequence:

request url - > Servlet ( load spring framework ) - > call controller ( return modelAndView ) - > print jsp ( with data );
