How to integrate an old Struts application with Spring 3.x -

-

i wondering how , prefered way of integrating struts 1.x application spring 3.x can benefit ioc stuff.

use contextloaderplugin , set struts controller processorclass "autowiringrequestprocessor" (in struts-config.xml):

<controller>     <set-property property="processorclass" value="org.springframework.web.struts.autowiringrequestprocessor" /> </controller>  <plug-in classname="org.springframework.web.struts.contextloaderplugin">     <set-property property="contextconfiglocation" value="/web-inf/config/action-servlet.xml"/> </plug-in>

action-servlet.xml has empty beans context file:

<beans></beans>

add following init parameter actionservlet in web.xml:

<init-param>     <param-name>autowire</param-name>     <param-value>byname</param-value> </init-param>

just write regular struts actions, , add annotation "@component" every action spring discover actions , creates bean out of it. "autowiringrequestprocessor" find right bean matches action class defined in struts-config.xml.

it's possible have other beans injected action class @autowired on setter(s).
