Question

I am having a used defined intercepter,from the intercepter i want to make a db call through DAO layer, so how can i inject spring bean to struts intercepter.is it possible

Answer 1

EDIT

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

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

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

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

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

private DaoService daoServiceBean; // Autowired by Spring
