各種開源框架環境及下載：
Hibernate：3.x http://www.hibernate.org/ 需要hibernate core 和annotations 包。
Spring：2.x http://springframework.org/
Struts2：2.x http://struts.apache.org/2.x/
ExtJS：2.X http://extjs.com/
JSON：JSON可以到http://www.json.org/ 查看詳細內容，這裏使用json-lib http://json-lib.sourceforge.net/
本所需要的包：
2、 配置：
（1）首先是配置web.xml，配置方法可以在下面的配置文件代碼註釋中查看，這裏主要是Struts2的配置：
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
和Spring的配置：
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/*.xml</param-value>
</context-param>
<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
Web.xml的全部文件：
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>struts2</display-name>
<!-- Spring ApplicationContext配置文件的路徑,可使用通配符*，多個路徑用,號分隔,此參數用於後面的Spring-Context loader -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/*.xml</param-value>
</context-param>
<!-- 著名 Character Encoding filter -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<!-- struts2 濾鏡配置 -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!--Spring ApplicationContext 載入 ，必須-->
<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- Spring 刷新Introspector防止內存泄露 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>
<!-- session超時定義,單位爲分鐘 -->
<session-config>
<session-timeout>10</session-timeout>
</session-config>
<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>
</web-app>
（2）Hibernate配置：
<?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>
<!—-數據庫驅動類名稱 -->
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<!—-數據庫用戶名 -->
<property name="hibernate.connection.username">MY</property>
<property name="hibernate.default_schema">MY</property>
<!—-數據庫用戶密碼 -->
<property name="hibernate.connection.password">MY</property>
<!—-數據庫連接字符串-->
<property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:loon</property>
<property name="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</property>
<!—-控制檯是否輸出SQL語句 -->
<property name="hibernate.show_sql">true</property>
<mapping class="privilege.database.Level" />
</session-factory>
</hibernate-configuration>
（3）Spring基本配置：配置文件應該在WEB-INF/spring/下面
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans default-autowire="autodetect">
<!—如果用的是XML配置文件，sessionFactory用這個配置 "org.springframework.orm.hibernate3.LocalSessionFactoryBean" -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="configLocation">
<value>classpath:hibernate.cfg.xml</value>
</property>
<!-- 配置多個hibernate.cfg.xml
<property name="configLocations">
<list>
<value>classpath:hibernate_admin1.cfg.xml</value>
<value>classpath:hibernate_admin2.cfg.xml</value>
</list>
</property>
-->
</bean>
<!-- Hibernate 事務管理 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<bean id="baseTransactionProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" abstract="true">
<property name="transactionManager" ref="transactionManager" />
<property name="transactionAttributes">
<props>
<prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="persist*">PROPAGATION_REQUIRED,-Exception</prop>
<prop key="remove*">PROPAGATION_REQUIRED,-Exception</prop>
<!--
<prop key="insert*">PROPAGATION_REQUIRED</prop>
<prop key="save">PROPAGATION_REQUIRED</prop>
<prop key="update*">PROPAGATION_REQUIRED</prop>
<prop key="edit*">PROPAGATION_REQUIRED</prop>
<prop key="del*">PROPAGATION_REQUIRED</prop>
<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="query*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="disPlay*">PROPAGATION_REQUIRES_NEW</prop>
-->
</props>
</property>
</bean>
<bean id="LevelService" parent="baseTransactionProxy">
<property name="target">
<bean class="privilege.service.LevelService">
<property name="dao">
<bean class="privilege.dao.LevelDAO">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
</property>
</bean>
</property>
</bean>
<bean id="LevelAction" class="privilege.action.LevelAction">
<property name="levelService" ref="LevelService" />
</bean>
</beans>
（4）struts.xml文件的配置：
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="privilege" extends="struts-default">
<action name="LoadLevel" class="LevelAction" method="findLevelById">
<result>/resource/json_struts2.jsp</result>
</action>
<action name="LevelAjaxJsonData" class="LevelAction" method="jsonExecute">
<result>/resource/json_struts2.jsp</result>
</action>
</package>
</struts>
3、 建立的項目目錄：
Root：
/resource/ext2.0/ 將下載的ext-2.0-beta1.zip文件解壓到該目錄
/WEB-INF/web.xml
/WEB-INF/lib
/WEB-INF/classes/struts.xml
/WEB-INF/spring/applicationContext.xml
4、 代碼清單：
Level.java
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "LOON_LEVEL")

<property name="sessionFactory" ref="sessionFactory" />
</bean>
</property>
</bean>
</property>
</bean>
<bean id="LevelAction" class="privilege.action.LevelAction">

配置struts.xml:
添加操作配置：
