《struts2权威指南》学习笔记之struts2整合jsf

1.安装jsf插件

为了在struts2应用中使用JSF组件（实际上就是MyFaces组件，因为Myfaces是jsf的一个实现，必须将myfaces的lib路径下的jar文件都复制到web应用的WEB-INF/lib下）

2.将struts2框架下的struts2-jsf-plugin-2.06.jar复制到WEB-INF/lib下

3.修改web.xml文件，增加MYFaces的支持

web.xml

<?xmlversion="1.0"encoding="UTF-8"?>
<web-appid="jsf"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/j2eehttp://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

</filter>

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

<filter-mapping>
<filter-name>struts</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<listener>

</listener>

<servlet>
<servlet-name>faces</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>

</servlet>

<!--JavaServerFacesServletMapping,notcalleddirectly-->
<servlet-mapping>
<servlet-name>faces</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
</web-app>

applicationContext.xml

<?xmlversion="1.0"encoding="GBK"?>
<!--指定Spring配置文件的Schema信息-->
<beansxmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd">

<beanid="bs"class="service.BookService"/>

</beans>

我们在spring配置文件中没有定义action的bean,所以，我们采用自动装配的方式将该业务逻辑注入到action实例中，为了让struts2使用spring框架，我们需要加入struts2-spring-plugin-2.0.6.jar到WEB-INF/lib中

并在struts.properties做如下定义

struts.i18n.encoding=gb2312
struts.objectFactory.spring.autoWire=type

struts.xml

<?xmlversion="1.0"encoding="GBK"?>

如果context为test,则运行哦哪个http://localhost:8080/test/list.action进行测试，不能直接运行list.jsp
