Spring_1.2.7 、 webwork_2.2.2及hibernate3的集成

1. 到webwork官网下载webwork-2.2.2.zip、spring_1.2.7.zip及hibernate3相关类包,获取webwork-2.2.2.jar以及lib/default 目录下的核心必须类包,同时获得spring1.2.7.jar以及hibernate3的hibernate3.jar，jta.jar，ehcache-1.1.jar等包，在构建web工程时需要放到工程类库目录中;

2. 编辑webwork_2.2.7在web工程中的配置文件,包括xwork.xml、webwork-default.xml、webwork.tld、webwork.properties、web.xml以及专门为注册事务编写的action配置文件login.xml，另外还要编辑spring的相关配置文件applicationContext.xml以及hibernate的配置，该配置没有单独作为配置文件，而是在applicationContext.xml文件中配置sessionFactory的时候在其<property name="hibernateProperties">属性配置，具体内容请见配置文件, User实体bean的对象关系映射文件User.hbm.xml,其目录结构如下图:

3. web.xml配置文件说明与举例,web.xml配置文件在WEB-INF目录下,是所有web工程都必须的配置文件,使用webwork框架,需要在改配置文件里面注册webwork框架插件来处理web请求,举例如下:

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app

PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

"http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>

<display-name>Test v2.0</display-name>

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>

/WEB-INF/classes/spring/applicationContext.xml

</param-value>

</context-param>

<filter-name>Encoding</filter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>

<param-value>GBK</param-value>

</init-param>

</filter>

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

</listener>

<listener-class>com.opensymphony.webwork.spring.lifecycle.SpringExternalReferenceResolverSetupListener</listener-class>

</listener>

<listener-class>com.opensymphony.webwork.spring.WebWorkSpringObjectFactory</listener-class>

</listener>

<servlet-name>webwork</servlet-name>

<servlet-class>com.opensymphony.webwork.dispatcher.ServletDispatcher</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>webwork</servlet-name>

<url-pattern>*.action</url-pattern>

</servlet-mapping>

<welcome-file-list>

<welcome-file>register.jsp</welcome-file>

</welcome-file-list>

<taglib-uri>webwork</taglib-uri>

<taglib-location>/WEB-INF/webwork.tld</taglib-location>

</taglib>

</web-app>

4. xwrok.xml配置说明与举例,该文件在类的根目录下,在web工程中应放在src目录下,工程编译后就会导入class目录下,即类根目录.其作用:webwork插件,在此也可以称做web请求处理分派器,分派器会根据该配置文件将web请求交给相应的Action处理,举例如下:

<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd">

<xwork>

<interceptor-stack name="standard-interceptors">

<interceptor-ref name="externalReferences" />

<interceptor-ref name="prepare" />

<interceptor-ref name="static-params" />

<interceptor-ref name="params" />

<interceptor-ref name="conversionError" />

</interceptor-stack>

<interceptor-stack name="stand-upload-interceptors">

<interceptor-ref name="externalReferences" />

<interceptor-ref name="prepare" />

<interceptor-ref name="fileUpload" />

<interceptor-ref name="static-params" />

<interceptor-ref name="params" />

<interceptor-ref name="conversionError" />

</interceptor-stack>

</interceptors>

<default-interceptor-ref name="standard-interceptors" />

</package>

</xwork>

5. login.xml 配置文件说明与举例,专门用来配置LoginAction,该配置文件会被包含入xwork.xml配置文件，这样才能生效,举例如下:

<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd">

<xwork>

<external-ref name="userService" required="true">UserService</external-ref>

<param name="location">register.jsp</param>

</result>

<param name="location">register.jsp</param>

</result>

<param name="location">register.jsp</param>

</result>

</action>

</package>

</xwork>

注意：externalReferenceResolver="com.opensymphony.xwork.spring.SpringExternalReferenceResolver" 告知spring框架在需要时配置action内实体之间的映射关系，例如：<external-ref name="userService" required="true">UserService</external-ref>就会引用spring配置的userService对象

6. webwork.properties配置说明与举例 ,此配置文件主要向webwork框架提供一些参数,如编码等,更多信息要查找相关文档,举例如下:

webwork.locale=zh_CN

webwork.i18n.encoding=GBK

7. applicationContext.xml 配置文件说明与举例,专门用来配置bean之间的依赖关系，在需要的时候进行动态的依赖注射,举例如下:

<?xml version="1.0" encoding="GBK"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

</bean>

</property>

<list>

<value>com/jetsum/test/entity/User.hbm.xml</value>

</list>

</property>

<props>

<prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>

</props>

</property>

</bean>

</property>

</bean>

</property>

<props>

<prop key="get*">PROPAGATION_SUPPORTS,readOnly</prop>

<prop key="*">PROPAGATION_REQUIRED</prop>

</props>

</property>

</bean>

</property>

</bean>

</property>

</bean>

</property>

</bean>

</beans>

8. User.hbm.xml 配置文件说明实体bean User.java与数据库中表user的对象关系映射,举例如下:

<?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>

</generator>

</id>

<property

name="name"

type="java.lang.String"

update="true"

insert="true"

column="name"

length="100"

name="password"

type="java.lang.String"

update="true"

insert="true"

column="password"

</class>

</hibernate-mapping>
