WEB4JJava Web應用框架

WEB4J是一個Java Web應用框架，目標是讓使用者建立簡單，清晰和優(yōu)雅的web應用。該框架同時也提供一個開發(fā)者工具來協(xié)助開發(fā)人員創(chuàng)建基于 WEB4J的 應用程序。

下面是一個 WEB4J 的Action類源碼：

package hirondelle.electricity.main.report;

import hirondelle.electricity.util.TemplatedPage;
import hirondelle.web4j.model.AppException;
import hirondelle.web4j.action.ActionImpl;
import hirondelle.web4j.request.RequestParser;
import hirondelle.web4j.action.ResponsePage;
import hirondelle.web4j.database.SqlId;

public class ReportAction extends ActionImpl {
  
  public static final SqlId LIST_HIGH_SPENDING = new SqlId("LIST_HIGH_SPENDING");
  
  public ReportAction(RequestParser aRequestParser){
    super(FORWARD, aRequestParser);
  }
  
  @Override public ResponsePage execute() throws AppException {
    ReportDAO dao = new ReportDAO();
    addToRequest(ITEMS_FOR_LISTING, dao.list());
    return getResponsePage();
  }

  // PRIVATE //
  private static final ResponsePage FORWARD = TemplatedPage.get(
    "Example Report", "view.jsp", ReportAction.class
  );
}
