segmentweb

A macro groovy web framework inspired by sparkjava.

Main Classes

1. Handler.groovy -> http request handler base class.
2. ChainHandler.groovy -> routes.
3. RouteRefreshLoader.groovy -> a watch dog to recompile Groovy file modified.
4. CachedGroovyClassLoader.groovy -> cache parsed Groovy classes from file or script text.

Unit tests using Spock

Chain operation style
