2.1、Struts2.0.14 2
2.2、Spring2.5.4 2
2.3、Hibernate3.2.5 3
2.4、jQuery 4
三、所需jar包 4
四、项目目录 5
五、整合步骤 6
5.1、spring 6
5.2、struts 7
5.3、hibernate 7
六、开发步骤 11
6.1、配置xml文件 11
6.2、编写pojo对象并生成与数据库对应的hbm.xml文件。 16
6.3、编写操作数据库的Dao类 16
6.4、编写业务逻辑代码 18
6.5、编写action类 20
6.6、编写JSP页面 23

一、开发工具
MyEclipse7.0
MySql5.0
JDK1.6
Jboss5.0

二、开发框架
    2.1、Struts2.0.14
Struts是一个在JSP Model2基础上实现的MVC框架，主要分为模型(Model)、视图(Viewer)和控制器(Controller)三部分，其主要的设计理念是通过控制器将表现逻辑和业务逻辑解耦，以提高系统的可维护性、可扩展性和可重用性。Struts框架的体系结构如图所示：

视图（Viwer）：视图部分主要由JSP页面组成，其中不包括业务逻辑和持久化操作，数据由struts标签或jstl标签呈现在页面上。
控制层(Controller）：控制层由FilterDispatcher组成，FilterDispatcher负责过滤接收HTTP请求，然后根据配置文件(struts.xml)调用相关的Action。
模型(Model)：struts1中有ActionFormBean作为模型，但在struts2中，ActionFormBean与Action合并，就没有严格意义上的模型了。一般由持久化对象作为模型。

2.2、Spring2.5.4
Spring是一个轻量级的MVC框架，在SSH框架整合中，Spring作为一个管理者，管理和提供项目中的所有组件。Spring框架体系结构如图：

2.3、Hibernate3.2.5
Hibernate对数据进行持久化，运用O/R mapping对关系型数据库和java对象进行映射，简化了开发人员对数据库的操作。Hibernate原理图如下：

2.4、jQuery
Jquery是继prototype之后又一个优秀的Javascrīpt框架。它是轻量级的js库，兼容CSS3，还兼容各种浏览器（IE 6.0+, FF 1.5+, Safari 2.0+, Opera 9.0+）。jQuery使用户能更方便地处理HTML documents、events、实现动画效果，并且方便地为网站提供AJAX交互。jQuery还有一个比较大的优势是，它的文档说明很全，而且各种应用也说得很详细，同时还有许多成熟的插件可供选择。jQuery能够使用户的html页保持代码和html内容分离，也就是说，不用再在html里面插入一堆js来调用命令了，只需定义id即可。
只需要在页面上导入jQuery的包就可以使用该框架了，具体的语法参照http://www.w3school.com.cn/jquery/

三、所需jar包
dom4j.jar
hibernate.jar
log4j.jar
mysql-connectior-java.jar
proxool.jar
proxool-cglib.jar
spring-beans.jar
spring-context.jar
spring-core.jar
spring-orm.jar
spring-tx.jar
spring-web.jar
spring-webmvc-struts.jar
struts2-core.jar
struts2-spring-plugin.jar
xwork.jar
commons-logging.jar
jta.jar
commons-collections.jar
cglib-nodep.jar
antlr.jar

四、项目目录
java目录

说明：
config：存放项目的配置文件
common：存放公共组件，如影片关联的显示，打印，日志导出等等
action：存放action模块
service：存放业务逻辑模块
hibernateDao：存放对数据库的操作类
entity：存放POJO对象及hbm.xml文件
exception：存放自定义的异常类
log：存放项目日志

页面目录

hotelPortal：存放Portal端的页面
hotelmanager：存放管理端的页面
js：存放js文件
css：存放css样式文件

五、整合步骤
5.1、spring
在web.xml中加入下面的监听代码告知项目使用spring框架：
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
同时设置application-context.xml文件的位置以便系统加载，如果不做该设置，系统默认加载/WEB-INF/applicationContext.xml文件：
<context-param>
      <param-name>
contextConfigLocation
</param-name>
      <param-value>
classpath*:/application/application-context.xml
</param-value>
</context-param>
application-context.xml文件管理中的所有组件，空文件内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-2.5.xsd ">
</beans>
现在spring框架就搭建好了。

5.2、struts
struts1与struts2相比，变化比较大，在web.xml文件中， struts1采用<servlet>的方式，而struts2中要配置成<filter>形式，具体配置如下：
<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>
struts1中配置文件为struts-config.xml，路径为/WEB-INF/struts-config.xml，在struts2中配置文件为struts.xml，路径为/WEB-INF/classes/struts.xml，空的struts.xml内容为：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
      "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
      "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>

</struts>

5.3、hibernate
在这里配合proxool数据库连接池一起使用，首先在web.xml中加入proxool的配置：
<servlet>
    <servlet-name>ServletConfigurator</servlet-name>
    <servlet-class>
      org.logicalcobwebs.proxool.configuration.ServletConfigurator
    </servlet-class>
    <init-param>
      <param-name>xmlFile</param-name>
      <param-value>/WEB-INF/proxool.xml</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
</servlet>

<servlet>
    <servlet-name>Admin</servlet-name>
    <servlet-class>
      org.logicalcobwebs.proxool.admin.servlet.AdminServlet
    </servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Admin</servlet-name>
    <url-pattern>/admin</url-pattern>
</servlet-mapping>
创建proxool.xml文件用来配置数据库连接信息，并将该文件放在/WEB-INF目录下
proxool.xml:
<?xml version="1.0" encoding="UTF-8"?>
<something-else-entirely>
<proxool>
    <alias>dbname</alias>
    <driver-url>jdbc:mysql://192.168.111.204:3306/lws</driver-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>
    <driver-properties>
      <property name="user" value="root"/>
      <property name="password" value="123456"/>
    </driver-properties>
    <maximum-connection-count>1000</maximum-connection-count>
    <minimum-connection-count>100</minimum-connection-count>
    <house-keeping-sleep-time>90000</house-keeping-sleep-time>
    <maximum-new-connections>10</maximum-new-connections>
    <prototype-count>10</prototype-count>
    <simultaneous-build-throttle>20</simultaneous-build-throttle>
    <test-before-use>false</test-before-use>
    <house-keeping-test-sql>select 1 from dual</house-keeping-test-sql>
</proxool>
</something-else-entirely>
如果将proxool.xml放置在其他位置，需要在<param-value>/WEB-INF/proxool.xml</param-value>处指定位置。
创建hibernate-connection.xml文件，放在与application-context.xml同级的目录下
hibernate-connection.xml：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-2.5.xsd ">

<bean id="dataSource"    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="org.logicalcobwebs.proxool.ProxoolDriver" />
    <property name="url" value="proxool.dbname" />
</bean>

<bean name="sessionFactory" scope="singleton" lazy-init="true"        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="mappingResources" ref="hibernateMappingResources" />
        <property name="hibernateProperties" ref="hibernateProperties" />
    </bean>

<bean name="hibernateMappingResources" scope="singleton" lazy-init="true"
    class="org.springframework.beans.factory.config.ListFactoryBean">
    <property name="targetListClass" value="java.util.ArrayList" />
    <property name="sourceList">
      <list>
        <!—- 这里是对象的hbm.xml文件 -->
        <value>XXX/XXX.hbm.xml</value>
      </list>
    </property>
</bean>

<bean name="hibernateProperties" scope="singleton" lazy-init="true"
        class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="properties">
            <props>
                
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
                
                <prop key="hibernate.show_sql">false</prop>
                <prop key="hibernate.generate_statistics">true</prop>
                <prop key="hibernate.use_sql_comments">true</prop>
            </props>
        </property>
    </bean>
</beans>

Hibernate是根据对象的hbm.xml文件与数据库表信息相对应的，列入数据库中有student表：
CREATE TABLE `student` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`name` varchar(200) DEFAULT NULL,
`name_1` varchar(200) DEFAULT NULL,
`flag` varchar(200) DEFAULT NULL,
PRIMARY KEY (`id`)
)
创建一个名为StudentImpl的javaBean
StudentImpl.java:
public class StudentImpl implements Student
{
private long id;

private String name;

private String name_1;

private String flag;

    //get和set方法略去
}
在Student.hbm.xml中将javaBean和数据库student表对应
Student.hbm.xml：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping
    PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

<hibernate-mapping>
<class name="entity.student.StudentImpl" table="student">
    <id name="id" type="java.lang.Long" column="id">
      <generator class="native">
<param name="sequence">SQ_Student_Key</param>
</generator>
    </id>
    <property name="name" type="string" column="name" not-null="true" length="200"/>
    <property name="name_1" type="string" column="name_1" not-null="false" length="200"/>
    <property name="flag" type="string" column="flag" not-null="false" length="200"/>
</class>
</hibernate-mapping>
将对象hbm.xml文件的相对路径配置在hibernate-connection.xml里。
在spring的配置文件application-context.xml中加入hibernate-connection.xml的配置，使得加载spring同时加载hibernate。

六、开发步骤
6.1、配置xml文件
web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:com/kt/hotel/config/application.xml</param-value>
</context-param>

    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<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>

<servlet>
    <servlet-name>ServletConfigurator</servlet-name>
    <servlet-class>
      org.logicalcobwebs.proxool.configuration.ServletConfigurator
    </servlet-class>
    <init-param>
      <param-name>xmlFile</param-name>
      <param-value>WEB-INF/classes/com/kt/hotel/config/proxool.xml</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
</servlet>

<servlet>
    <servlet-name>Admin</servlet-name>
    <servlet-class>
      org.logicalcobwebs.proxool.admin.servlet.AdminServlet
    </servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Admin</servlet-name>
    <url-pattern>/admin</url-pattern>
</servlet-mapping>

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

struts.xml
用struts.xml来管理各个模块的struts配置
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
      "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
      "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
      <include file="com/kt/hotel/config/struts-movie.xml"></include>
</struts>

struts-movie.xml：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
      "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
      "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
      <package name="hotel" namespace=""
          extends="struts-default">

</something-else-entirely>

6.2、编写pojo对象并生成与数据库对应的hbm.xml文件。
   POJO对象和相应的hbm.xml文件已经建好，这里不做过多阐述。

6.3、编写操作数据库的Dao类
具体的数据库连接、释放等操作交给hibernate和数据库连接池去完成，下面以对影片对象进行添加和查询为例：
   首先创建EntityDao类，该类为抽象类，继承了HibernateDaoSupport类，且只有一个SessionFactory参数
EntityDao.java：
public abstract class EntityDao extends HibernateDaoSupport
{
@SuppressWarnings("unused")
private SessionFactory sessionFactory;
}
然后在config文件下创建hibernateDao.xml文件来管理dao的配置，在该xml文件中配置EntityDao并且注入sessionFactory
HibernateDao.xml：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-2.5.xsd ">

<import resource="classpath*:com/kt/hotel/hibernateDao/hibernateDao-movie.xml"/>
<bean id="entityDao" class="com.kt.hotel.hibernateDao.EntityDao" scope="singleton" abstract="true">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>
</beans>
注意：这里EntityDao要用abstract=”true”配置成抽象的。
接下来编写MovieDaoImpl类，该类是movie的dao类，继承抽象类EntityDao
MovieDaoImpl.java：
public class MovieDaoImpl extends EntityDao implements MovieDao{

public void add(MoviePO movie)
{
this.getHibernateTemplate().save(movie);
}

@SuppressWarnings("unchecked")
public List<MoviePO> getList()
{
String hql = "from MoviePO";
List<MoviePO> list = (List<MoviePO>)this.getHibernateTemplate().find(hql);
return list;
}
}
实现类MovieDaoImpl放在文件夹hibernateDao下的Impl目录里，接口类放在hibernateDao目录下，下面创建hibernateDao-movie.xml文件来管理影视的dao类
hibernateDao-movie.xml：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context

           http://www.springframework.org/schema/tx/spring-tx-2.5.xsd ">

<bean id="movieDao" class="com.kt.hotel.hibernateDao.impl.MovieDaoImpl" scope="singleton" parent="entityDao">
</bean>
</beans>
其中parent="entityDao"表示继承前面所配置的EntityDao类

6.4、编写业务逻辑代码
在service目录下创建impl目录，该目录存放业务逻辑的实现类。创建MovieServiceImpl.java类来调用MovieDao中的添加和显示方法，
MovieServiceImpl.java：
public class MovieServiceImpl implements MovieService {

private MovieDao movieDao;
public void add(MoviePO movie)
{
movieDao.add(movie);
}

public List<MoviePO> getList()
{
List<MoviePO> list = movieDao.getList();
return list;
}

@Required
public void setMovieDao(MovieDao movieDao) {
this.movieDao = movieDao;
}
}
在service目录下创建service-movie.xml管理影视的业务逻辑
service-movie.xml：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-2.5.xsd ">

<bean id="movieService" class="com.kt.hotel.service.impl.MovieServiceImpl" scope="singleton">
    <property name="movieDao" ref="movieDao" />
</bean>
</beans>
接着在config目录下创建service.xml文件管理各个模块的service-xxx.xml文件
service.xml：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-2.5.xsd ">

<import resource="classpath*:com/kt/hotel/service/service-movie.xml"/>

</beans>

6.5、编写action类
struts2.0与struts1.x差别很大，在struts2.0中action不需要继承任何类，切方法返回值是字符串，通过返回的字符串来找到相应的跳转页面，
MovieAction.java：
public class MovieAction {

private MovieService movieService;

private MoviePO movie;

public String add()
{
MoviePO entity = (MoviePO)movie;
movieService.add(entity);
HttpServletRequest request = ServletActionContext.getRequest();
request.setAttribute("forwardPage", "movie!getList.action");

return "addSuccess";
}

public String getList()
{
List<MoviePO> list = movieService.getList();
HttpServletRequest request = ServletActionContext.getRequest();
request.setAttribute("movieList", list);
return "movieList";
}

public String forwardAddPage()
{

return "addMoviePage";
}

@Required
public void setMovieService(MovieService movieService) {
this.movieService = movieService;
}

public void setMovie(MoviePO movie) {
this.movie = movie;
}

public MoviePO getMovie() {
return movie;
}
}
其中MovieService是要注入的影视业务类，MoviePO是POJO对象，如果用request，需通过ServletActionContext来获取。
在action目录创建action-movie.xml文件来管理影视的action
action-movie.xml：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-2.5.xsd ">

<bean id="movieAction" class="com.kt.hotel.action.MovieAction" scope="prototype">
    <property name="movieService" ref="movieService" />
</bean>
</beans>
注意：这里的id=”movieAction”的值要与struts.xml中配置的class相一致，
如movieAction对应struts.xml中
<action name="movie" class="movieAction">
              <result name="movieList">/page/hotelManager/video/movie/movieList.jsp</result>
              <result name="addMoviePage">/page/hotelManager/video/movie/addMovie.jsp</result>
              <result name="addSuccess">/page/hotelManager/common/addSuccess.jsp</result>
          </action>
class=”movieAction”的movieAction，url中使用/movie就对应到movieAction，然后在action-movie.xml中找到movieAction对应的com.kt.hotel.action.MovieAction类。
<result name="movieList">...</result>中的movieList对应于MovieAction文件中getList方法返回的值，以此来确定跳转的页面。如果方法的返回值在struts.xml中没有找到，会报404错误

然后在config下创建一个action.xml文件管理各个模块的action-xxx.xml文件
action.xml：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx-2.5.xsd ">

<import resource="classpath:com/kt/hotel/action/action-movie.xml"/>
</beans>
访问路径是由工程名，struts.xml配置的action对应的name和Action类中的方法名来指定的，如上例，工程名为hotel，struts.xml中action定义的name是movie，对应action类MovieAction.java中的方法名是getList()和add()如果要调用getList()方法，url为：http://<ip>:<port>/hotel/movie!getList.action，如果要调用add方法，路径为
http://<ip>:<port>/hotel/movie!add.action

6.6、编写JSP页面
在JSP页面使用jstl标签来显示内容。首先在JSP页面加入jstl标签库
<%@taglib prefix="c" uri="http://java.sun.com/jstl/core_rt"%>
<%@taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt"%>
<%@taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%@taglib prefix="s" uri="/struts-tags" %>
然后就可以使用这些标签了，下面是在movieList.jsp页面用<c:forEach>来循环显示
<c:forEach items="${movieList}" var="movie">
      <tr align="center">
        <td width="5%"><input type="checkbox" name="movie"></td>
        <td width="10%">${movie.name}</td>
        <td width="15%">${movie.actor}</td>
        <td width="15%">${movie.price}</td>
        <td width="10%"><a href="javascript:void(0);">修改</a></td>
      </tr>
    </c:forEach>
其中movieList是在action类中，通过request.setAttribute传到页面上的列表。

addMovie.jsp页面中<input type="text" name="movie.name" size="20">的movie.name要注意，这是struts2.0的新写法，movie对应于MovieAction中定义的movie属性，和setMovie和getMovie方法一起构成了formBean，页面上通过movie.name标示，把值映射到MoviePO对象的name属性中。
