Spring Roo

What is Spring Roo?

● Spring Roo is a next-generation rapid application development tool for Java developers. With Roo you can easily build full Java applications in minutes. It differs from other productivity tools by focusing on:Rapid resultsRapid results 100% develop in Java100% develop in Java

● Here's just some of the technologies that Roo-based projects can instantly leverage.

Productivity without compromise

● Roo's innovative approach is free of any compromises:

– Program in Java!

– Full IDE support (with features like code assist, refactoring and debugging)

– No runtime portion, which means easier adoption in enterprise with approval requirements

– Excellent runtime performance, as there's no runtime memory usage, deployment footprint, control flow invocation time etc

Productivity without compromise (2)

● Lower risk of bugs impacting your project, as Roo operates entirely at development time (just like your IDE)

● No lock-in to Roo, as you can remove it from your project in just minutes

● Easy extensibility to new features thanks to OSGi-based add-on extensibility

● We could go on, but you get the point: Roo doesn't make you compromise (ever) :-)

How it works● In a nutshell, Roo is a lightweight console shell that

you load up while developing your projects. While the Roo shell can be used to complete time-consuming operations in just one quick command, most of the time you'll just ignore Roo and go off and develop your project in your IDE or text editor.

● As you go about editing code in your normal way, Roo keeps an eye on your project files and automatically modifies them in response to your actions. Depending on the Roo add-ons you have running, Roo can help you with different types of files.

How to install Roo

● If you downloaded the standalone Spring Roo, simply unzip it to a location of your choice. Then:

– Windows users: add %ROO_HOME%\bin to your path

– *nix users: create a symbolic link to $ROO_HOME/bin/roo.sh (eg sudo ln -s ~/spring-roo-1.x.x/bin/roo.sh /usr/bin/roo)
