WEB4JJava Web应用框架

WEB4J是一个Java Web应用框架，目标是让使用者建立简单，清晰和优雅的web应用。该框架同时也提供一个开发者工具来协助开发人员创建基于 WEB4J的 应用程序。

下面是一个 WEB4J 的Action类源码：

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
  );
}
