Create servlet for standalone execution of templates about thymeleaf HOT 11 CLOSED

+1 would love to see this

from thymeleaf.

@danielfernandez What kind of servlet do you envision for this? I already run a Spring-less Thymeleaf site, so I could just extract my template servlet into its own library (much like I did with the layout dialect) or as an extra?

from thymeleaf.

I think this is the Velocity servlet that Daniel told about http://velocity.apache.org/tools/devel/view.servlet.html

from thymeleaf.

Basically, I thought of this as a way to create thymeleaf-only web applications in a similar fashion to the way people can create ASP-only web applications on an IIS or JSP-only web applications on a Tomcat/Jetty/whatever.

This is, a servlet that takes URLs (probably only .html URLs) and redirects them to thymeleaf templates which will do the processing.

And what processing, you might ask, if by the time we have our thymeleaf template executing itself we will have no context at all? Correct, but we will have two things:

• The URL parameters, accessible with ${param.*}
• Our beautiful future shiny SQL dialect :-D defined in #36

And those should be enough to get data to work with in a Thymeleaf-only way...

I'll see what I can get going for this sometime this week as well. I'll just throw it into one of my own repos for you to evaluate. I should also be able to get it working much more simply than the instructions on the Velocity page if I start with using Servlet 3.0 web fragments (sooo much easier than having to hack together the web.xml yourself), or maybe I'm just being too optimistic.

from thymeleaf.

So I got something going in this repo: https://github.com/ultraq/thymeleaf-template-servlet

It's a web fragment project, so can be imported into any web project and it'll automatically start working as per the config in the annotations here: StandaloneThymeleafServlet.java So the web container should support the Java web app 3.0 spec, and have annotation scanning turned on. (It shouldn't be too hard to create a non-annotation version, but I just went down this route because it's the easiest to get something going.) The init-params can also be overridden by developers in their web.xml files.

I created a mini web app (it's an Eclipse project, so is pretty hard to share right now) that imported this project and then had just HTML files in the web content folder. I could then go http://localhost:8080/test-project/path-to-html-file.html and voila! Thymeleaf template :)

Oh, that's a nice toy!

I will try it at the end of this week, maybe doing an example application.

@ultraq Oops! I still haven't had a look at that! :-$

from thymeleaf.

The standalone servlet was integrated in the example app at https://github.com/jmiguelsamper/thymeleaf-extras-sqldialect which now is listed on the ecosystem page.

The only outstanding question is whether integrate the servlet into the Thymeleaf core or not.

from thymeleaf.

I think it shouldn't be core, and just get a mention in the ecosystem page like your SQL dialect and then we'll support them like we do with our other Thymeleaf add-on projects.
