    We can create custom Struts action in Liferay by using Hooks, these type of Hook is called as Liferay Struts Action Hook.

    Follow the below steps to create a Struts Action:

    1. Create Liferay Plugin Project of type Hook.

    1. Write the below code in liferay-hook.xml

    <?xml version="1.0"?>
    <!DOCTYPE hook PUBLIC "-//Liferay//DTD Hook 6.2.0//EN" "http://www.liferay.com/dtd/liferay-hook_6_2_0.dtd">
    
    <hook>
        <portal-properties>portal.properties</portal-properties> 
        <custom-jsp-dir>/META-INF/custom_jsps</custom-jsp-dir>
        <struts-action>
            <struts-action-path>/portal/createActionExample</struts-action-path>
            <struts-action-impl>com.evon.action.CustomAction</struts-action-impl> 
        </struts-action>  
    </hook>
    

    1. Create demo.jsp in the portal directory. We can add this jsp by JSP Hook in docroot/META-INF/custom_jsps/html/portal directory:

    <h3>Welcome! you are redirected here from Custom Struts Action class CustomAction</h3>
    

    1. Now create CustomAction class for Struts action as below. CustomAction class extends BaseStrutsAction but not BaseStrutsPortletAction. By this way we add action class in portal level.

    package com.evon.action;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    import com.liferay.portal.kernel.struts.BaseStrutsAction;
    
    public class CustomAction extends BaseStrutsAction{
    
        @Override
        public String execute(HttpServletRequest request,
                HttpServletResponse response) throws Exception {
    
            return "/portal/demo.jsp";
        }
    
    }
    

    1. If you want to make struts action path to be public then create portal.properties in docroot/WEB-INF/src and write the below line in portal.properties

    auth.public.paths=/portal/createActionExample
    

    1. Deploy the Hook and access the http://localhost:8080/c/portal/createActionExample URL. It will display demo.jsp page and you will see the message that we have defined in that jsp.

    Hope this will help you :)
