struts2 的action：


<action name="pic_*" class="PicUploadAction" method="{1}">
<interceptor-ref name="defaultStack"></interceptor-ref>
<!-- 是struts2为我们提供的文件上传的拦截器 -->
<interceptor-ref name="fileUpload">
<!--允许上传的类型 -->
<param name="allowedTypes">image/gif,image/jpeg</param>
<!-- 允许文件大小 -->
<param name="maximumSize">20000000</param>
</interceptor-ref>
<result name="success">admin/pictureShow.jsp</result>
<result name="error">/admin/main.jsp</result>
<result name="input">/upload.jsp</result>
</action>


spring的 bean 配置：
<!-- pic -->

<bean id="PicBizImp" class="com.biz.PicBizImp" scope="prototype">
<property name="picdao" ref="PfpictureDAO"></property>
</bean>
<bean id="PicUploadAction" class="com.action.PicUploadAction">
<property name="picbiz" ref="PicBizImp"></property>
</bean>
