I know this question is subjective but I would really want to know what are the best j2ee web application auto code generators.

I googled and found out the Appfuse is one of them.

Spring ROO is another but it depends on spring i think.

Are there any other better tools?

Basically lot of time is spent on creating regular CRUD screens with the same mundane things for each screen.

So, I would want to reduce the time spent on such simple CRUD screens so that I can focus more on开发者_StackOverflow社区 the core application logic.

We use Telosys (http://www.telosys.org/) to generate repetitive code like CRUD screens. A set of templates are available for Spring MVC, JPA, AngularJS, etc. We have customized some of them. It saves of lot of time.

The best solution I have seen so far is Grails. It generates groovy code, not java but you can interface painlessly with any java library/class. The convention over configuration features are amazing and one can put up a functioning web app in minutes.

I suggest you see for yourself - just try the grails screencasts. They will get you up to speed in 15 minutes.

The technologies used under the hood are best-of-breed : spring, hibernate, lucene, quartz, sitemesh etc.
