急!!!spring整合问题

[Tito10]

请问下大家,为什么我用struts执行到action里面,业务层的对象要通过在struts-config.xml里面配置个
<controller>
<set-property perty="processorClass"
value="org.springframework.web.struts.DelegatingRequestProcessor" />
</controller>
才能被实例化呢?

现在我进到了业务层的方法里面,dao的对象又没有实例化了,要怎么配置才能让dao实例化呢?下面是我applicationContext.xml的代码
<?xml version="1.0" encoding="UTF-8"?>

<controller>
<set-property perty="processorClass"
value="org.springframework.web.struts.DelegatingRequestProcessor" />
</controller>
是为了添加spring对web的支持框架
你的applicationContext.xml中
<bean name="/reg" class="com.yyun.struts.action.UserAction">
<property name="biz">
<ref local="custProxy"/>
</property>
</bean>
</beans>
name = "/reg"就是web的请求表示,引入那个类就是为了解析/reg. 不然的话你在学spring的时候不是要用MyBean mybean = (MyBean) factory.getBean("mybean");没发现现在不用了嘛..

你的UserInfoDAO应该被实例化了,如果你说的是ReleaseInfoDAO没被实例化的话,是因为,我没发现他在哪被关联

问题解决了 我是将<bean name="/reg" class="com.yyun.struts.action.UserAction">
<property name="biz">
<ref local="custProxy这个换成了userManageService"/>
</property>
</bean>
但是这样就没有实现AOP了是吗？
要怎样才能通过代理来实现呢？

[hwy000]

是的,你可以通过custProxy来获取userManageService
<bean id="custProxy" parent="txProxyTemplate">
<property name="target">
<ref bean="userManageService"/>
</property>
