Dropwizard hot deployment

Question

I'm looking for a simple to use system in Java which creates a REST service for me. So I found dropwizard but as far as I can use google it turns out it lacks hot deployment although jetty is able to do so. When using the maven-shade-plugin it takes at least 10 seconds to build the thing. Also my IDE reports that it cannot use compile on save feature (aka hot deployment) when the shade-plugin is involved.

Can I use hotdeployment somehow? Or what can I use instead?

Update: If nothing will fix this I'll probably use a combination of jersey&guice etc which is explained in this post

Would using a servlet 3.0 container be an option? I believe it can do what you need just from annotations in your code. – Confess

@ThorbjørnRavnAndersen do you have a simple example where I can see this? – Tiddlywinks

Answer 1

You don't have to use the shade plugin to run your service. You could just compile as a regular jar file and I think that would let you use your IDEs hot deployment features.

the shaded jar is mostly useful for deployment – Guerin

Answer 2

Have you ever tried JRebel ? They have JAX-RS support as well...

Answer 3

Not an answer, but I wrote up an article detailing how to use git to push a Dropwizard project to your server and for it to initiate a hot replacement. It relies on git hooks and running Maven via a script on the server.

You can find the details about it here: http://gary-rowe.com/agilestack/2013/02/14/how-to-deploy-dynamic-sites-with-git/

this is not hot deployment. hot deployment is when you can edit your java files, hit save, your IDE compiles and jetty restarts within 1 second with the updated class file – Tiddlywinks

That's why I wrote replacement - not deployment. Apologies for the confusion. Edited the answer to make this clearer. – Ine

Hmmh ... also this script is suboptimal (I've a better one ;)) as it stops the site and starts compiling afterwards!? It should compile first and only if test passes restart the server! – Tiddlywinks

The article does state that it is for development purposes and that a production version would be coded differently. If you'd like to post your improved version then I can add it to the article as a suggested approach with full credit to you. – Ine
