1.表结构

DDL信息
create tableCREATE TABLE `sys` (
   `id` int(11) NOT NULL AUTO_INCREMENT,
   `username` varchar(50) NOT NULL,
   `password` varchar(50) NOT NULL,
   `realname` varchar(50) DEFAULT NULL,
   `company` varchar(50) DEFAULT NULL,
   PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8 COMMENT='系统用户表'2.UserDAO

package com.lc.dao;import org.hibernate.*;import com.lc.pojo.*;public class UserDAO {public void addUser(Sys sys){//创建sessionSession s = HibernateSessionFactory.getSession();//创建事务处理对象Transaction t = s.beginTransaction();//执行操作s.save(sys);//提交事务t.commit();//关闭sessions.close();}public void delUser(Sys sys){Sys mySys = null;//创建sessionSession s = HibernateSessionFactory.getSession();//创建事务处理对象Transaction t = s.beginTransaction();//执行操作mySys = (Sys)s.get(sys.getClass(), sys.getId());s.delete(mySys);//提交事务t.commit();//关闭sessions.close();}}

3.添加用户-AddUserAction

/* * Generated by MyEclipse Struts * Template path: templates/java/JavaClass.vtl */package com.lc.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.lc.dao.UserDAO;import com.lc.pojo.Sys;import com.lc.struts.form.SysForm;/**  * MyEclipse Struts * Creation date: 08-29-2012 *  * XDoclet definition: * @struts.action path="/AddUserAction" name="SysForm" scope="request" validate="true" */public class AddUserAction extends Action {/* * Generated Methods *//**  * Method execute * @param mapping * @param form * @param request * @param response * @return ActionForward */public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) {SysForm SysForm = (SysForm) form;// TODO Auto-generated method stubUserDAO user = new UserDAO();Sys sys = new Sys(SysForm.getUsername(), SysForm.getPassword(), SysForm.getRealname(), SysForm.getCompany());user.addUser(sys);return null;}}

4.删除用户-DelUserAction

/* * Generated by MyEclipse Struts * Template path: templates/java/JavaClass.vtl */package com.lc.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.lc.dao.UserDAO;import com.lc.pojo.Sys;import com.lc.struts.form.DelForm;/**  * MyEclipse Struts * Creation date: 08-29-2012 *  * XDoclet definition: * @struts.action path="/DelUserAction" name="DelForm" scope="request" validate="true" */public class DelUserAction extends Action {/* * Generated Methods *//**  * Method execute * @param mapping * @param form * @param request * @param response * @return ActionForward */public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) {DelForm DelForm = (DelForm) form;// TODO Auto-generated method stubUserDAO user = new UserDAO();Sys sys = new Sys();sys.setId(Integer.parseInt(DelForm.getUserid()));user.delUser(sys);return null;}}
