2.Struts中的Action类
 

package com.tanm.struts.action;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;

import com.tanm.dao.factory.DAOFactory;

import com.tanm.struts.form.LoginForm;

import com.tanm.vo.Person;

public class LoginAction extends Action {

    public ActionForward execute(ActionMapping mapping, ActionForm form,

           HttpServletRequest request, HttpServletResponse response) {

       LoginForm loginForm = (LoginForm) form;

       // 从ActionForm中取出要的内容

       Person person = new Person();

       person.setId(loginForm.getId());

       person.setPassword(loginForm.getPassword());

       boolean flag = false;

       flag = DAOFactory.getPersonDAOInstance().isLogin(person);

       request.setAttribute("flag", new Boolean(flag));

       if (flag) {

           // 如果成功,将person对象传递出去

           // request.getSession().setAttribute("persons", person);

           request.setAttribute("per", person);    //注意per与jsp页面中bean:write的per相对应  
           return mapping.findForward("success");

       } else {

           return mapping.findForward("failure");

       }

    }

}
