Description

struts2 supports sitemesh2.4 now, WW-3291
I'd like to extends the default OldDecorator2NewStrutsFreemarkerDecorator to do something fantastic,like compress page,render html fragment for AJAX request
I with struts provide a @Inject way.

here is sample code

public class MyOldDecorator2NewStrutsFreemarkerDecorator extends OldDecorator2NewStrutsFreemarkerDecorator {

public static final String X_FRAGMENT = "X-FRAGMENT";

public MyOldDecorator2NewStrutsFreemarkerDecorator(Decorator oldDecorator)

{ super(oldDecorator); }

protected void render(Content content, HttpServletRequest request,
HttpServletResponse response, ServletContext servletContext,
ActionContext ctx) throws ServletException, IOException {
String replacement = request.getHeader(X_FRAGMENT);
if (replacement != null)

{ StringWriter writer = new StringWriter(); content.writeBody(writer); response.getWriter().write(HtmlUtils.compress(replacement.split(","), writer.toString())); return; }

else

{ super.render(content, request, response, servletContext, ctx); }

}

}
