ExtJs、Struts2、Hibernate3.2登录页面的简单实现

1、思想的大致模型

2、建立数据库test和数据库表tb_user

1 CREATEDATABASE `test`;
2 CREATETABLE `test`.`tb_user` (
3 `username` varchar(20) NOTNULL,
4 `password` varchar(20) NOTNULL,
5 PRIMARYKEY (`username`)
6 ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

3、加入基本的struts包

3.1、加入struts2的基本包

commons-fileupload-1.2.1.jar

commons-io-1.3.2.jar

freemarker-2.3.16.jar

javassist-3.7.ga.jar

ognl-3.0.jar

struts2-core-2.2.1.jar

xwork-core-2.2.1.jar

3.2、加入struts.xml文件到myeclipse6.5工程里的src，文件内容为

1 <?xml version="1.0" encoding="UTF-8" ?>
2  <!DOCTYPE struts PUBLIC
3 "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
4 "http://struts.apache.org/dtds/struts-2.0.dtd">
5
6  <struts>
7 <package name="Service" extends="struts-default">
8 
9 <action name="login_post" class="Service.Login"></action>
10 </package>
11 
12  </struts>
13

3.3、配置WebRoot里的Web-INF的web.xml文件内容为

1 <?xml version="1.0" encoding="UTF-8"?>
2  <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
5 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
6 <filter>
7 <filter-name>struts2</filter-name>
8 <filter-class>
9 org.apache.struts2.dispatcher.FilterDispatcher
10 </filter-class>
11 </filter>
12 <filter-mapping>
13 <filter-name>struts2</filter-name>
14 <url-pattern>/*</url-pattern>
15 </filter-mapping>
16 <welcome-file-list>
17 <welcome-file>index.jsp</welcome-file>
18 </welcome-file-list>
19  </web-app>
20

4、配置hibernate3.2

4.1、项目->点击右键->MyEclipse->Add HibernateCapabilities…

4.2、配置hibernate.xml文件

1 <?xml version=‘1.0‘ encoding=‘UTF-8‘?>
2 <!DOCTYPE hibernate-configuration PUBLIC
3 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
4 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
5
6 
7 <hibernate-configuration>
8
9 <session-factory>
10 <property name="connection.username">root</property>
11 <property name="connection.url">
12 jdbc:mysql://localhost:3306
13 </property>
14 <property name="dialect">
15 org.hibernate.dialect.MySQLDialect
16 </property>
17 <property name="myeclipse.connection.profile">mysql</property>
18 <property name="connection.password">123</property>
19 <property name="connection.driver_class">
20 com.mysql.jdbc.Driver
21 </property>
22 
23 <property name="current_session_context_class">thread</property>
24 <property name="show_sql">true</property>
25 <property name="format_sql">true</property>
26 
27 <property name="connection.useUnicode">true</property>
28 <property name="connection.characterEncoding">UTF-8</property>
29 <mapping resource="Model/TbUser.hbm.xml"/>
30
31 </session-factory>
32
33 </hibernate-configuration>
