How to do dynamic URL redirects in Struts 2?

Question

I\'m trying to have my Struts2 app redirect to a generated URL. In this case, I want the URL to use the current date, or a date I looked up in a database. So /section/

Answer 1

I ended up subclassing Struts' ServletRedirectResult and overriding it's doExecute() method to do my logic before calling super.doExecute(). it looks like this:

public class AppendRedirectionResult extends ServletRedirectResult {
   private DateFormat df = new SimpleDateFormat("yyyy-MM-dd");

  @Override
  protected void doExecute(String finalLocation, ActionInvocation invocation) throws Exception {
    String date = df.format(new Date());
    String loc = "/section/document/"+date;
    super.doExecute(loc, invocation);
  }
}

I'm not sure if this is the best way to do it, but it works.
