surveyaction.java

简单的网上调查系统。采用Spring+Hibernate方式设计架构。

package com.mySurvey.action;
//导入Java类
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
//导入spring的类
import org.springframework.web.servlet.ModelAndView;

import org.springframework.web.servlet.mvc.SimpleFormController;
//导入mySurvey的相关类
import com.mySurvey.bean.Survey;
import com.mySurvey.domain.SetSurvey;
//该类作为设定调查名称的初始的控制器
public class SurveyAction implements Controller{
	private String viewPage;
//	定义要依赖注入的处理逻辑setSurvey
	private SetSurvey setSurvey;
	//实现onSubmit（）方法
    public ModelAndView handleRequest(HttpServletRequest req, HttpServletResponse res) throws Exception {
        Map model = new HashMap();
		List listSurveys = new ArrayList();
		//获取已有的调查名称
		listSurveys = getSetSurvey().querySurvey();
		//将已有的调查名称传递给页面
		model.put("listSurveys", listSurveys);
        //返回的页面
