2、WebWork2与SpringFramework集成的配置
（1）ww2/WEB-INF/applicationContext.xml
l 由于不使用Spring MVC Framework实现Web表示层，将业务逻辑层和数据持久层组件的Bean配置从springapp-servlet.xml中移到applicationContext.xml中
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName"><value>com.mysql.jdbc.Driver</value></property>
<property name="url">
<value>jdbc:mysql://localhost/test</value>
</property>
<property name="username"><value>test</value></property>
<property name="password"><value>test</value></property>
</bean>
<bean id="prodManDao" class="db.ProductManagerDaoJdbc">
<property name="dataSource">
<ref bean="dataSource"/>
</property>
</bean>
<bean id="prodMan" class="bus.ProductManager">
<property name="productManagerDao">
<ref bean="prodManDao"/>
</property>
</bean>
</beans>
（2）ww2/WEB-INF/web.xml
l 在web.xml中增加2个context监听器
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
<listener-class>com.atlassian.xwork.ext.ResolverSetupServletContextListener</listener-class>
</listener>
（3）ww2/WEB-INF/classes/xwork.xml
<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd">
<xwork>
<include file="webwork-default.xml"/>
<package name="default" extends="webwork-default"
externalReferenceResolver="com.atlassian.xwork.ext.SpringServletContextReferenceResolver">
<interceptors>
<interceptor name="reference-resolver"
class="com.opensymphony.xwork.interceptor.ExternalReferencesInterceptor"/>
<interceptor-stack name="externalStack">
<interceptor-ref name="reference-resolver"/>
<interceptor-ref name="defaultStack"/>
</interceptor-stack>
<interceptor-stack name="externalValidationWorkflowStack">
<interceptor-ref name="reference-resolver"/>
<interceptor-ref name="validationWorkflowStack" />
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="externalStack"/>
<action name="springapp"
class="web.SpringappAction">
<external-ref name="prodMan">prodMan</external-ref>
<result name="success" type="velocity">
<param name="location">/WEB-INF/template/hello.vm</param>
</result>
<!--
<result name="success" type="dispatcher">
<param name="location">/WEB-INF/jsp/hello.jsp</param>
</result>
-->
</action>
<action name="priceIncreaseForm"
class="web.PriceIncreaseForm">
<result name="success" type="velocity">
<param name="location">/WEB-INF/template/priceincrease.vm</param>
</result>
<!--
<result name="success" type="dispatcher">
<param name="location">/WEB-INF/jsp/priceincrease.jsp</param>
</result>
-->
</action>
<action name="priceIncrease"
class="web.PriceIncreaseFormAction">
<external-ref name="prodMan">prodMan</external-ref>
<result name="input" type="velocity">
<param name="location">/WEB-INF/template/priceincrease.vm</param>
</result>
<!--
<result name="input" type="dispatcher">
<param name="location">/WEB-INF/jsp/priceincrease.jsp</param>
</result>
-->
<result name="success" type="chain">
<param name="actionName">springapp</param>
</result>
<interceptor-ref name="externalValidationWorkflowStack" />
</action>
</package>
</xwork>
l XWork使用外部引用来使用Spring Bean配置中的引用，这需要：
l 在<package>标记中指定外部引用解析器为com.atlassian.xwork.ext.SpringServletContextReferenceResolver
l 重新组合Interceptor堆栈，以包含com.opensymphony.xwork.interceptor.ExternalReferencesInterceptor；这里定义了两个Interceptor堆栈：externalStack和externalValidationWorkflowStack，前者被定义为缺省Interceptor引用，后者被需要数据有效性验证的Action引用
l 最后，使用<external-ref>标记在Action中引用外部的Spring Bean（有关Action的配置会在后面详述）
