由于不需要将 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 Actions 完全一样，除了(如果我没记错的话)在 beans.xml 中声明它的例外，因为拦截器不扩展 ActionSupport(默认情况下是自动装配的).

Exactly the way you do with Actions , with (if I remember well) the exception of declaring it in beans.xml because Interceptors don't extend ActionSupport (that is autowired by default) .

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"/>

<罢工>

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

Struts.xml

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

<package ...>
    <interceptors>

<罢工>

        <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
