    text
    copied!<p>I've used the Struts 2 framework and I have created a web application which has a Login Page. I have three different <code>Action</code> classes named <code>Action1</code>, <code>Action2</code>, <code>Action3</code>, and different views for JSP pages which are rendered by running some business logic in the <code>Action</code> classes.</p> <p>Now, I want to check whether a user has logged in before the <code>Action</code> class carries out processing. So, I created an interceptor below that works fine.</p> <pre><code>public String intercept(ActionInvocation invocation) throws Exception { HttpServletRequest request = ServletActionContext.getRequest(); HttpServletResponse response = ServletActionContext.getResponse(); HttpSession session = request.getSession(); if(session.isNew()) { response.sendRedirect("Login.action"); } System.out.println("Interceptor Fired"); String result = invocation.invoke(); return result; } </code></pre> <p>What I want to be in <code>struts.xml</code> is instead of adding an interceptor for all the actions like the one below</p> <pre><code>&lt;interceptor-ref name="newStack"/&gt; </code></pre> <p>My <code>struts.xml</code> file has</p> <pre><code>&lt;package name="default" extends="struts-default"&gt; &lt;interceptors&gt; &lt;interceptor name="printMsgInterceptor" class="LoginInterceptor"&gt;&lt;/interceptor&gt; &lt;interceptor-stack name="newStack"&gt; &lt;interceptor-ref name="printMsgInterceptor"/&gt; &lt;interceptor-ref name="defaultStack" /&gt; &lt;/interceptor-stack&gt; &lt;/interceptors&gt; &lt;action name="actone" class="Action1"&gt; &lt;result name="success"&gt;/success.jsp&lt;/result&gt; &lt;interceptor-ref name="newStack"/&gt; &lt;/action&gt; &lt;action name="acttwo" class="Action2"&gt; &lt;result name="success"&gt;/success.jsp&lt;/result&gt; &lt;interceptor-ref name="newStack"/&gt; &lt;/action&gt; &lt;action name="actthree" class="Action3"&gt; &lt;result name="success"&gt;/success.jsp&lt;/result&gt; &lt;interceptor-ref name="newStack"/&gt; &lt;/action&gt; &lt;/package&gt; </code></pre> <p>For every action I want to have some definition written in <code>struts.xml</code> which runs the interceptor rather than manually adding </p> <pre><code>&lt;interceptor-ref name="newStack"/&gt; </code></pre>
