JFlask
JFlask is now deprecated. See flak instead.
JFlask is a micro web framework for Java inspired by Python Flask.
Here is an example of what a small JFlask web app looks like.
package samples;
import net.jflask.App;
import net.jflask.Route;
package samples;
import net.jflask.App;
import net.jflask.Route;
public class WebApp {
public static void main(String[] args) throws Exception {
App app = new App(Integer.getInteger("port", 8080));
// NB: it is cleaner to define route handler in dedicated classes
app.scan(new Object() {
@Route("/hello/:name")
public String hello(String name) {
return "Hello " + name;
}
});
// static resources are served from local file system or directly
// from the web-app jar
app.servePath("/", "app/");
app.start();
System.out.println("Listening on http://0.0.0.0:" + app.getPort());
}
