一、配置檔案
1.1 jdbc配置檔案
1.2 mybatis配置檔案
1.3 spring-mybatis配置檔案
1.4 springmvc配置檔案
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd"> <!-- 註解的對映器和介面卡 --> <mvc:annotation-driven> </mvc:annotation-driven> <!-- 附件掃描器 會掃描指定包下面的controller、service、repository等註解 springIoc容器會幫助咱們建立和依賴注入po --> <context:component-scan base-package="cn/edu360/ssm"></context:component-scan><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 配置jsp路徑的字首 --> <property name="prefix" value="/WEB-INF/pages/" /> <!-- 配置jsp路徑的字尾 --> <property name="suffix" value=".jsp" /> </bean> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 設定上傳檔案的最大尺寸為1MB --> <property name="maxUploadSize"> <value>1048576</value> </property> </bean> <mvc:interceptors> <!-- session的攔截器，預設會按照順序進行處理 --> <mvc:interceptor> <!-- 許可權攔截路徑 --> <mvc:mapping path="/*"/> <bean class="cn.edu360.ssm.Interceptor.SessionInterceptor"></bean> </mvc:interceptor> <!-- 許可權的攔截器 --> <!-- <mvc:interceptor> <mvc:mapping path="/**"/> <bean class="cn.edu360.ssm.intercepter.PermIntercepter"></bean> </mvc:interceptor> --> </mvc:interceptors> </beans>
二、Controller層
package cn.edu360.ssm.controller; import java.io.UnsupportedEncodingException; import java.net.URLEncoder; import java.text.SimpleDateFormat; import java.util.Collections; import java.util.Date; import java.util.List; import javax.annotation.Resource; import javax.servlet.http.Cookie; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import cn.edu360.ssm.model.News; import cn.edu360.ssm.service.NewsService; @Controller public class NewsController { @Resource private NewsService newsService; //跳轉到釋出新聞介面 @RequestMapping("/publishNews.shtml") public String publishNews() { return "publishNews"; } //插入新聞 @RequestMapping("/insertNews.shtml") public String InsertNews(News news, HttpServletRequest request, HttpServletResponse response) { if(news.getTitle().trim().equals("") || news.getTitle().trim().equals("")) { return "redirect:newsHref.shtml"; } Date date = new Date(); SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd:HH:mm"); String date2String = format.format(date); news.setDate(date2String); newsService.insertNews(news); Cookie[] cookies = request.getCookies(); if(cookies != null) { for(Cookie cookie : cookies) { if(cookie.getName().equals("newsTitle") || cookie.getName().equals("newsBody")) { cookie.setMaxAge(0); response.addCookie(cookie); } } } return "redirect:newsHref.shtml"; } //查詢新聞將url顯示在介面 @RequestMapping("/newsHref.shtml") public String searchNewsHref(Model model) { List<News> newList = newsService.findAllNewsHref(); Collections.reverse(newList); model.addAttribute("newsList", newList); return "news"; } //按照url後的id查詢新聞 @RequestMapping("/newsView.shtml") public String findNewsById(int newsId, HttpServletRequest request) { News news = newsService.findNewsById(newsId); request.getSession().setAttribute("news", news); return "newsView"; } //儲存新聞cookie @RequestMapping("/save.shtml") public String saveNewsCookie(News news, HttpServletRequest request, HttpServletResponse response) { Cookie newsTitleCookie = null; Cookie newsBodyCookie = null; try { newsTitleCookie = new Cookie("newsTitle", URLEncoder .encode(news.getTitle(), "utf-8")); newsBodyCookie = new Cookie("newsBody", URLEncoder .encode(news.getBody(), "utf-8")); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } // 對中文編碼儲存 newsTitleCookie.setMaxAge(60 * 60 * 24); newsTitleCookie.setPath("/ssm"); response.addCookie(newsTitleCookie); newsBodyCookie.setMaxAge(60 * 60 * 24); newsBodyCookie.setPath("/ssm"); response.addCookie(newsBodyCookie); return "redirect:index.shtml"; } }
三、Service層
3.1 介面
3.2 實現類
四、DAO層
4.1 介面
4.2 mybatis配置實現
