[jira] [Updated] (WW-3328) make sitemesh plugin OldDecorator2NewStrutsFreemarkerDecorator configurable

     [ https://issues.apache.org/jira/browse/WW-3328?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Lukasz Lenart updated WW-3328:
------------------------------
    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);
		}
	}

}
