问卷调查系统说明(14)

本系统涉及的业务逻辑相对简单，因此在设计的时候，我们将其并入MVC控制层，在控制层中直接调用DAO处理对象持久化操作。————————————SurveyManage.java begin————————

…

public class SurveyManage extends HttpServlet {

private static final long serialVersionUID = -1737458302140188798L;

public void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

PrintWriter out=response.getWriter();

if(“AddSurvey”.equals(request.getParameter(“op”))){

SurveyDAO surveydao=DAOFactory.getSurveyDAO(); //获取DAO对象

Survey survey=new Survey();//构造VO对象

survey.setSName(request.getParameter(“Survey_name”));//给VO 对象赋值

survey.setSAuthor(request.getParameter(“Survey_author”));
