Hello folks,

I have a project with the following setup:

Tomcat 6.x
Struts 2.1.6
DisplayTag 1.2
Spring 2.x (1 or 5, don't remember now)

I want to know to to do session controlling in every action of my app, like if the users weren't logged in, they're redirect to certain page to login (in the case of my project, either the user come to a special crafted url like login/SPECIALHASHTOLOGIN or won't enter at all.

Need more details?

Thx in advance.

I'll need modify the default interceptor stack (or create a custom stack) and add a custom interceptor. This custom interceptor will need to implement SessionAware to access the user session, and must implement your custom logic (which action to redirect to, which URLs do not need protection, etc.).

Here is a good tutorial of a LoginInterceptor that behaves similar to what you are requesting:

Some samples of struts.xml and applicationContext.xml
struts.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

    <package name="renaconPackage" extends="struts-default">
	 	<interceptors>
	 		<interceptor name="login" class="loginInterceptor"/>
			
			<!-- stack seguro -->	  	    
			<interceptor-stack name="defaultLoginStack">

		</interceptors>  	  	
	  	
	  	<!-- mudando o default stack para nosso stack seguro -->
	  	<default-interceptor-ref name="defaultLoginStack" />
	  	 
	  	 
		<!--

		<action name="*/*" class="{1}Action" method="{2}">

            <result>/pages/{1}/{2}.jsp</result>
        </action>			 
    </package>
 
</struts>
 
 
 
ApplicationContext.xml (only the needed part):
 
	<!-- servicos -->
 	<bean id="usuarioService" class="br.com.autenticis.renacon.ejb.UsuarioBean" />
    
    <!-- actions que necessitam de servicos injetados -->
    <bean id="usuarioAction" scope="prototype" class="br.com.autenticis.renacon.actions.UsuarioAction">
        <constructor-arg ref="usuarioService" />
    </bean>
 
    <bean id="loginInterceptor" scope="prototype" class="br.com.autenticis.renacon.actions.interceptors.LoginInterceptor">
        <constructor-arg ref="usuarioService" />
    </bean>
