[置顶] S2SH+DWR实现的增删改查实例
一、介绍
主要技术:
(1)s2sh之间的整合
(2)dwr和s2sh整合(验证姓名是否相同)
(3)强大的jquery validator验证框架验证表单
(4)分页bean的编写
(5)过滤器，拦截器的编写
(6)泛型dao的编写
二、实例
1、数据库脚本
本例是采用mysql数据库，脚本如下:
CREATE DATABASE /*!32312 IF NOT EXISTS*/`practice` /*!40100 DEFAULT CHARACTER SET gbk */; USE `practice`; DROP TABLE IF EXISTS `student`; CREATE TABLE `student` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(50) DEFAULT NULL, `age` int(11) DEFAULT NULL, `sex` varchar(1) DEFAULT NULL, `address` varchar(100) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=31 DEFAULT CHARSET=gbk; insert into `student`(`id`,`name`,`age`,`sex`,`address`) values (2,'张民生',24,'男','江苏淮安市'),(26,'李军',41,'男','江苏南京'),(27,'李丽丽',25,'女','浙江杭州'),(28,'周塔利',36,'男','黑龙江'),(29,'李丽',24,'女','湖北'),(30,'凯萨',21,'女','新疆乌鲁木齐'); DROP TABLE IF EXISTS `users`; CREATE TABLE `users` ( `id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(50) DEFAULT NULL, `password` varchar(50) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=gbk; insert into `users`(`id`,`username`,`password`) values (1,'admin','123456');

4、逻辑处理Action层
BaseAction.java
package com.anxin.struts.action; import com.anxin.util.OVLoadProperties; import com.anxin.util.PageListData; import com.opensymphony.xwork2.ActionSupport; public class BaseAction extends ActionSupport{ protected PageListData pageListData;//分页组件 protected int currentPage=1;//当前页 protected int pageSize=Integer.parseInt(OVLoadProperties.getInstance().getProperties("pageSize"));//每页显示的数目 protected int querytype;//查询类型 protected String condition;//查询条件 public PageListData getPageListData() { return pageListData; } public void setPageListData(PageListData pageListData) { this.pageListData = pageListData; } public int getCurrentPage() { return currentPage; } public void setCurrentPage(int currentPage) { this.currentPage = currentPage; } public int getPageSize() { return pageSize; } public void setPageSize(int pageSize) { this.pageSize = pageSize; } public int getQuerytype() { return querytype; } public void setQuerytype(int querytype) { this.querytype = querytype; } public String getCondition() { return condition==null?"":condition.trim(); } public void setCondition(String condition) { this.condition=(condition==null?"":condition.trim()); } }

5、公用的一些类
OpenSessionInViewFilter.java(重写spring包中的OpenSessionInViewFilter类，目的是解决事务提交出现的bug)
package com.anxin.util; import org.hibernate.FlushMode; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.springframework.dao.DataAccessResourceFailureException; import org.springframework.orm.hibernate3.SessionFactoryUtils; public class OpenSessionInViewFilter extends org.springframework.orm.hibernate3.support.OpenSessionInViewFilter { /** * we do a different flushmode than in the codebase * here */ protected Session getSession(SessionFactory sessionFactory) throws DataAccessResourceFailureException { Session session = SessionFactoryUtils.getSession(sessionFactory, true); session.setFlushMode(FlushMode.COMMIT); return session; } /** * we do an explicit flush here just in case * we do not have an automated flush */ protected void closeSession(Session session, SessionFactory factory) { session.flush(); super.closeSession(session, factory); } }
PageListData.java(分页组件)
package com.anxin.util; import java.util.ArrayList; import java.util.List; import java.util.Locale; import javax.servlet.http.HttpServletRequest; public class PageListData { // 分页结果集 private List dataList = null; // 记录总数 private int totalcount = 0; // 每页显示记录数 private int pageSize = 0; // 当前页数 private int currentPage = 1; // 总页数 private int totalPageCount = 1; //分页页脚 private String footer; /*初始化分页组件*/ public PageListData(int totalcount, int pageSize, int currentPage, List dataList) { setTotalcount(totalcount); setPageSize(pageSize); setCurrentPage(currentPage); setDataList(dataList); setFooter(getFooter()); } /** * 封装分页栏函数 必需被包含在某个Form之中 * * @return String pages 当前页号 pageSize 每页显示行数 */ public String getFooter() { StringBuffer pageStr = new StringBuffer(""); pageStr.append("<center><p class='pages'>"); int totalPages = getTotalPageCount(); // 总页数 int prevPage = currentPage - 1; // 上一页 int nextPage = currentPage + 1; // 下一页 pageStr.append("<span style="color:#6795B4;" mce_style="color:#6795B4;">共有" + totalcount + "条记录</span> "); pageStr.append("<span style="color:#6795B4;" mce_style="color:#6795B4;">第" + currentPage + "页/共" + totalPages + "页</span> "); if (currentPage > 1) pageStr .append("<span><a style="cursor: pointer;text-decoration:underline;color:#6795B4" mce_style="cursor: pointer;text-decoration:underline;color:#6795B4"onclick='document.getElementById(/"pages/").value=1;document.getElementById(/"pages/").form.submit();'>首页</a></span> "); if (currentPage == 1) pageStr .append("<span style="color:#6795B4" mce_style="color:#6795B4">首页</span> "); if (currentPage > 1) pageStr .append("<span><a style="cursor: pointer;text-decoration:underline;color:#6795B4" mce_style="cursor: pointer;text-decoration:underline;color:#6795B4" onclick='document.getElementById(/"pages/").value=" + prevPage + ";document.getElementById(/"pages/").form.submit();'>上一页</a></span> "); if (currentPage <= 1) pageStr .append("<span style="color:#6795B4" mce_style="color:#6795B4">上一页</span> "); if (currentPage < totalPages) pageStr .append("<span><a style="cursor: pointer;text-decoration:underline;color:#6795B4;" mce_style="cursor: pointer;text-decoration:underline;color:#6795B4;" onclick='document.getElementById(/"pages/").value=" + nextPage + ";document.getElementById(/"pages/").form.submit();'>下一页</a></span> "); if (currentPage >= totalPages) pageStr .append("<span style="color:#6795B4;" mce_style="color:#6795B4;">下一页</span> "); if (currentPage < totalPages) pageStr .append("<span><a style="cursor: pointer;text-decoration:underline;color:#6795B4;" mce_style="cursor: pointer;text-decoration:underline;color:#6795B4;" onclick='document.getElementById(/"pages/").value=" + totalPages + ";document.getElementById(/"pages/").form.submit();'>末页</a></span> "); if (currentPage == totalPages) pageStr .append("<span style="color:#6795B4;" mce_style="color:#6795B4;">末页</span> "); pageStr .append("<span style="color:#6795B4;" mce_style="color:#6795B4;">跳转至第:<input type='text' value='" + currentPage + "'id='jumpPageBox' size='2' onblur='checkCurrentPage(document.getElementById(/"jumpPageBox/").value," + totalPages + ")'/>页<input class='right-button02' type='button' value='跳转' onclick='document.getElementById(/"pages/").value=document.getElementById(/"jumpPageBox/").value;document.getElementById(/"pages/").form.submit();'/></span>"); pageStr.append("</p></center>"); pageStr.append("<input type='hidden' value='" + currentPage + "' name='currentPage' id='pages' />"); pageStr.append("<input type='hidden' value='" + pageSize + "' name='pageSize' id='pageSize' />"); return pageStr.toString(); } public List getDataList() { return dataList; } public void setDataList(List dataList) { this.dataList = dataList; } public int getTotalcount() { return totalcount; } public void setTotalcount(int totalcount) { this.totalcount = totalcount; } public int getPageSize() { return pageSize; } public void setPageSize(int pageSize) { this.pageSize = pageSize; } public int getCurrentPage() { return currentPage; } public void setCurrentPage(int currentPage) { this.currentPage = currentPage; } //计算总页数，如果为0则置为1 public int getTotalPageCount() { int p; if (totalcount % pageSize == 0) { p=totalcount / pageSize; } else { p=totalcount / pageSize + 1; } return p==0?1:p; } public void setTotalPageCount(int totalPageCount) { this.totalPageCount = totalPageCount; } public void setFooter(String footer) { this.footer = footer; } }
OVLoadProperties.java(读取properties文件的内容)
package com.anxin.util; import java.io.FileInputStream; import java.io.IOException; import java.io.InputStream; import java.util.Properties; //单例模式实现读取zxc.properties文件的内容 public class OVLoadProperties { // 声明一个自己的实例 private static OVLoadProperties instance = new OVLoadProperties(); final static String fileName = "/config.properties"; // 返回该实例 public static synchronized OVLoadProperties getInstance() { return instance; } // 获取key所对应的值 public String getProperties(String key) { Properties p = new Properties(); InputStream is = null; try { // zxc.properties文件放在src目录的下边 is = OVLoadProperties.class.getResourceAsStream(fileName); if (is == null) is = new FileInputStream(fileName); p.load(is); } catch (Exception e) { System.out.println("加载文件出错啦!" + e.getMessage()); } finally { if (is != null) { try { is.close(); } catch (IOException e) { // TODO Auto-generated catch block System.out.println(e.getMessage()); } } } return p.getProperty(key); } }

6、过滤器和拦截器
LoginFilter.java(jsp页面过滤器)
package com.anxin.filter; import java.io.IOException; import javax.servlet.Filter; import javax.servlet.FilterChain; import javax.servlet.FilterConfig; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; import com.anxin.bean.User; public class LoginFilter implements Filter{ public void destroy(){ } public void doFilter(ServletRequest request,ServletResponse response,FilterChain chain) throws IOException,ServletException{ HttpSession session=((HttpServletRequest)request).getSession(); ((HttpServletResponse)response).setHeader("Pragma","No-cache"); ((HttpServletResponse)response).setHeader("Cache-Control","no-cache"); ((HttpServletResponse)response).setHeader("Cache-Control", "no-store"); ((HttpServletResponse)response).setDateHeader("Expires",0); User user=(User)session.getAttribute("user"); String url=(((HttpServletRequest)request).getRequestURI()); if(url.endsWith("/login.jsp")||url.endsWith("/BaseProject/")){ chain.doFilter(request, response); }else{ if(session.getAttribute("user")==null){ ((HttpServletResponse)response).sendRedirect(((HttpServletRequest)request).getContextPath()+"/login.jsp"); }else{ chain.doFilter(request, response); } } } public void init(FilterConfig filterConfig)throws ServletException{ } }
LoginedCheckInterceptor(action拦截器)
package com.anxin.struts.interceptor; import javax.servlet.http.HttpServletResponse; import org.apache.struts2.ServletActionContext; import com.anxin.bean.User; import com.opensymphony.xwork2.ActionInvocation; import com.opensymphony.xwork2.interceptor.AbstractInterceptor; /** session过期、登录有效性及操作的权限验证拦截器 */ public class LoginedCheckInterceptor extends AbstractInterceptor { /** 拦截请求并进行登录有效性验证 */ public String intercept(ActionInvocation ai) throws Exception { //取得请求的URL String url = ServletActionContext.getRequest().getRequestURL().toString(); HttpServletResponse response=ServletActionContext.getResponse(); response.setHeader("Pragma","No-cache"); response.setHeader("Cache-Control","no-cache"); response.setHeader("Cache-Control", "no-store"); response.setDateHeader("Expires",0); User user = null; //对登录与注销请求直接放行,不予拦截 if (url.indexOf("user_login.action")!=-1 || url.indexOf("logout.action")!=-1){ return ai.invoke(); } else{ //验证Session是否过期 if(!ServletActionContext.getRequest().isRequestedSessionIdValid()){ //session过期,转向session过期提示页,最终跳转至登录页面 return "tologin"; } else{ user = (User)ServletActionContext.getRequest().getSession().getAttribute("user"); //验证是否已经登录 if (user==null){ //尚未登录,跳转至登录页面 return "tologin"; }else{ return ai.invoke(); } } } } }
7、S2SH整合核心配置文件
