1、倒包hibernate11个包+sturts2 13个包
2、创建web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>Test27</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
3、创建struts
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <!-- 设置过滤的扩展名 --> <constant name="struts.action.extension" value="do,action,,"></constant> <!-- 定义包 --> <package name="index" extends="struts-default"> <action name="addUser"> <result>/WEB-INF/pages/addUser.jsp</result> </action> <!-- 保存User --> <action name="saveUser" class="com.hanqi.action.UserAction" method="saveUser"> <result name="fail">/WEB-INF/pages/fail.jsp</result> <result >/WEB-INF/pages/success.jsp</result> </action> <!-- 查询用户 --> <action name="selectUser" class="com.hanqi.action.UserAction" method="selectUser"> <result name="fail">/WEB-INF/pages/fail.jsp</result> <result >/WEB-INF/pages/selectUser.jsp</result> </action> <!-- 删除用户 --> <action name="deleteUser" class="com.hanqi.action.UserAction" method="deleteUser"> <result name="fail">/WEB-INF/pages/fail.jsp</result> <result type="redirectAction">selectUser</result> </action> <!-- 修改用户 --> <action name="EditUser"> <result>/WEB-INF/pages/EditUser.jsp</result> </action> <action name="updateUser" class="com.hanqi.action.UserAction" method="updateUser"> <result name="fail">/WEB-INF/pages/fail.jsp</result> <result type="redirectAction">selectUser</result> </action> </package> </struts>
4、创建cfg.xml文件链接数据库
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property> <property name="hibernate.connection.password">123</property> <property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property> <property name="hibernate.connection.username">test0816</property> <property name="hibernate.default_schema">TEST0816</property> <property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property> <property name="hibernate.show_sql">true</property> <property name="hibernate.format_sql">true</property> <!-- 自动建表方式 --> <property name="hibernate.hbm2ddl.auto">update</property> <!-- 映射文件 --> <mapping resource="com/hanqi/entity/T_User.hbm.xml"/> </session-factory> </hibernate-configuration>
5、创建登陆界面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <a href="addUser">添加用户</a> <br><br> <a href="selectUser">查询用户列表</a> </body> </html>
6、按照MVC思想创建包和类
6.1创建实体类和对应的映射文件（可用反向工程）
package com.hanqi.entity; //持久化类 //不要使用final修饰 import java.util.Date; public class T_User { private Integer user_ID; private String name; private Date birthday; private double money; private String password; public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Integer getuser_ID() { return user_ID; } public void setuser_ID(Integer user_ID) { this.user_ID = user_ID; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } public double getMoney() { return money; } public void setMoney(double money) { this.money = money; } public T_User(Integer user_ID, String name, Date birthday, double money) { super(); this.user_ID = user_ID; this.name = name; this.birthday = birthday; this.money = money; } public T_User(Integer user_ID, String name) { super(); this.user_ID = user_ID; this.name = name; } //必须提供无参的构造方法 //需要用到反射 public T_User() { super(); } @Override public String toString() { return "User [user_ID=" + user_ID + ", name=" + name + ", birthday=" + birthday + ", money=" + money + ", password=" + password + "]"; } }
对应的映射文件：
<?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated 2016-11-16 14:30:38 by Hibernate Tools 3.4.0.CR1 --> <hibernate-mapping> <class name="com.hanqi.entity.T_User" table="T_USER"> <id name="user_ID" type="java.lang.Integer"> <column name="USER_ID" /> <generator class="native" /> </id> <property name="name" type="java.lang.String"> <column name="NAME" /> </property> <property name="birthday" type="java.util.Date"> <column name="BIRTHDAY" /> </property> <property name="money" type="double"> <column name="MONEY" /> </property> <property name="password" type="java.lang.String"> <column name="PASSWORD" /> </property> </class> </hibernate-mapping>
6.2创建action类
package com.hanqi.action; import java.util.Date; import java.util.List; import java.util.Map; import javax.servlet.http.HttpServletRequest; import org.apache.struts2.ServletActionContext; import com.hanqi.entity.T_User; import com.hanqi.service.UserService; import com.opensymphony.xwork2.ActionContext; public class UserAction { //域模型方式 private T_User user; private int userid; private String name; private String password; private Date birthday; private double money; public int getUserid() { return userid; } public void setUserid(int userid) { this.userid = userid; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } public double getMoney() { return money; } public void setMoney(double money) { this.money = money; } public T_User getUser() { return user; } public void setUser(T_User user) { this.user = user; } //处理保存User的方法 public String saveUser() { String rtn="fail"; try{ //调用Service层（模型层，业务逻辑层） T_User u1=new UserService().add(user); //使用request转发到下一个页面上去 ActionContext ac=ActionContext.getContext(); Map<String, Object>mo=(Map<String, Object>)ac.get("request"); mo.put("user", u1); rtn="success"; } catch(Exception e) { e.printStackTrace(); } return rtn; } //查询 public String selectUser() { String rtn="fail"; try{ //调用查询的方法 List<T_User> lu=new UserService().getAll(); //得到原生的request HttpServletRequest hsr=ServletActionContext.getRequest(); hsr.setAttribute("userlist", lu); rtn="success"; } catch(Exception e) { e.printStackTrace(); } return rtn; } //删除 public String deleteUser() { String rtn="fail"; try{ //获取userID //得到原生的request HttpServletRequest hsr=ServletActionContext.getRequest(); String uid=hsr.getParameter("userID"); //执行删除 new UserService().delete(Integer.parseInt(uid)); rtn="success"; } catch(Exception e) { e.printStackTrace(); } return rtn; } //执行修改 public String updateUser() { String rtn="fail"; try{ T_User user=new T_User(); user.setuser_ID(userid); user.setPassword(password); user.setName(name); user.setBirthday(birthday); user.setMoney(money); new UserService().update(user); rtn="success"; } catch(Exception e) { e.printStackTrace(); } return rtn; } }
6.3 创建service层
package com.hanqi.service; import java.util.List; import com.hanqi.DAO.UserDAO; import com.hanqi.entity.T_User; public class UserService { //添加user的方法 public T_User add(T_User user) { return new UserDAO().insert(user); } //全表查询 public List<T_User> getAll() { return new UserDAO().getAll(); } //删除 public void delete(int userID) { new UserDAO().delete(userID); } //单条查询 public T_User getUser(int userID) { return new UserDAO().getUser(userID); } //执行修改 public void update(T_User user) { new UserDAO().updateUser(user); } }
6.4 创建DAO层
package com.hanqi.DAO; import java.util.ArrayList; import java.util.List; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.boot.registry.StandardServiceRegistryBuilder; import org.hibernate.cfg.Configuration; import org.hibernate.service.ServiceRegistry; import com.hanqi.entity.T_User; public class UserDAO { private Configuration cfg=null; private ServiceRegistry sr=null; private SessionFactory sf=null; private Session se=null; private Transaction ts=null; public UserDAO() { cfg=new Configuration().configure(); sr=new StandardServiceRegistryBuilder() .applySettings(cfg.getProperties()).build(); } private void init() { sf=cfg.buildSessionFactory(sr); se=sf.openSession(); ts=se.beginTransaction(); } private void destory() { ts.commit(); se.close(); sf.close(); } //保存 user public T_User insert(T_User user) { init(); se.save(user); destory(); return user; } //查询列表 public List<T_User> getAll() { init(); List<T_User> rtn=new ArrayList<>(); rtn=se.createQuery("from T_User").list(); destory(); return rtn; } //删除 public void delete(int userID) { init(); //获取对象 T_User u=(T_User)se.get(T_User.class, userID); se.delete(u); destory(); } //单条查询 public T_User getUser(int userID) { init(); T_User rtn=null; rtn=(T_User)se.get(T_User.class, userID); destory(); return rtn; } //修改单条查询内容 public T_User updateUser(T_User user) { init(); T_User rtn=null; rtn=(T_User)se.get(T_User.class, user.getuser_ID()); rtn.setuser_ID(user.getuser_ID()); rtn.setName(user.getName()); rtn.setPassword(user.getPassword()); rtn.setBirthday(user.getBirthday()); rtn.setMoney(user.getMoney()); destory(); return rtn; } }
7、跳转页面
7.1添加用户页面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> 添加用户 <br><br> <form action="saveUser" method="post"> 用户名：<input type="text" name="user.name"/> <br> 密码：<input type="password" name="user.password"/> <br> 生日：<input type="text" name="user.birthday"/> <br> 薪酬：<input type="text" name="user.money"/> <br> <input type="submit" value="保存"/> </form> </body> </html>
7.2查询页面
<%@page import="com.hanqi.entity.T_User"%> <%@page import="java.util.List"%> <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <% List<T_User> lu=(List<T_User>)request.getAttribute("userlist"); for(T_User u:lu) { out.print(u + "【<a href='EditUser?userID="+u.getuser_ID()+"'>修改</a>】【<a href='deleteUser?userID="+u.getuser_ID()+"'>删除</a>】 <br>"); } %> </body> </html>
7.3 修改用户界面
<%@page import="com.hanqi.entity.T_User"%> <%@page import="com.hanqi.service.UserService"%> <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <% // 接收参数 String userID = request.getParameter("userID"); T_User us=null; if (userID == null || userID.trim().equals("")) { response.getWriter().print("请正确访问"); } else { us=new UserService().getUser(Integer.parseInt(userID)); } %> 编辑银行卡信息<br><br> <form action="updateUser" method="post"> 用户id号：<input type="text" name="userid" value="<%=us.getuser_ID() %>"readonly><br> 用户名：<input type="text" name="name" value="<%=us.getName() %>"/> <br> 密码：<input type="password" name="password" value="<%=us.getPassword() %>"/> <br> 生日：<input type="text" name="birthday" value="<%=us.getBirthday() %>"/> <br> 薪酬：<input type="text" name="money" value="<%=us.getMoney() %>"/> <br> <input type="submit" value="提交"/> </form> </body> </html>
7.4 操作失败的跳转页面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> 操作失败 </body> </html>
7.5 保存成功的跳转页面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> 操作成功 User=${user } </body> </html>
