由于没有必要将Interceptor声明为Spring bean，因此我删除了不必要的部分.感谢@AleksandrM对其进行测试.

Since there is no need to declare the Interceptor as Spring bean, I striked the unnecessary parts. Thanks to @AleksandrM for testing it.

与操作完全一样，但(如果我还记得的话)在bean.xml中声明它的例外，因为Interceptor不会扩展ActionSupport(默认情况下是自动连接的).

web.xml

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

ApplicationContext.xml

ApplicationContext.xml

<bean id="daoServiceBean" 
   class="org.foo.bar.business.dao.DaoService"/>

<bean id="myInterceptorBean" 
   class="org.foo.bar.presentation.interceptors.MyInterceptor"/>

Struts.xml

Struts.xml

<constant name="struts.objectFactory" value="spring" />

<package ...>
    <interceptors>

        <interceptor name="myInterceptor" class="myInterceptorBean" />

        <interceptor name="myInterceptor" 
                    class="org.foo.bar.presentation.interceptors.MyInterceptor"/>

MyInterceptor.java

MyInterceptor.java

private DaoService daoServiceBean; // Autowired by Spring
