1 RESTful service one-liner

Running this single line of code will start a web server embedded in your application.

By default, the server listens on port 8888 and address 0.0.0.0 (matching any IP address).

Navigating to http://localhost:8888/size?msg=abc will return 3.

// On GET /size return the length of the "msg" parameter

On.get("/size").json((String msg) -> msg.length());

GET /size?msg=abc

HTTP server routes information:

Verb	Path	Zone	Content type	MVC	View name	Roles
GET	/size	main	json

2 Instant web application

// On GET /hi or POST /hi return a "Hello World" web page

On.page("/hi").mvc("Hello <b>world</b>!");

config.yml

gui:

brand: 'Cool app!'

title: 'the head title'

search: true

menu:

Home: /

Portfolio: /portfolio

About:

About Us: /about

About You: /

Let's send some HTTP requests and check the results:

GET /hi

Hello world!

HTTP server routes information:

Verb	Path	Zone	Content type	MVC	View name	Roles
GET POST	/hi	main	html		hi

3 RESTful services with Lambda handlers, JPA, Jackson and Bean Validation

Main.java

import org.rapidoid.annotation.Valid;

import org.rapidoid.jpa.JPA;

import org.rapidoid.setup.App;

import org.rapidoid.setup.On;

public class Main {

public static void main(String[] args) {

App.bootstrap(args).jpa(); // bootstrap JPA

On.get("/books").json(() -> JPA.of(Book.class).all()); // get all books

On.post("/books").json((@Valid Book b) -> JPA.save(b)); // insert new book if valid

}

Book.java

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.Id;

import javax.validation.constraints.NotNull;

@Entity

public class Book {

@Id

@GeneratedValue

public Long id;

@NotNull

public String title;

public int year;

}

Let's send some HTTP requests and check the results:

POST /books {"title":"Java Book","year":2016}

{"id":1,"title":"Java Book","year":2016}

GET /books

[{"id":1,"title":"Java Book","year":2016}]

POST /books {"year":2004}

{"error":"Validation failed: Book.title (may not be null)","code":422,"status":"Unprocessable Entity"}

GET /books

[{"id":1,"title":"Java Book","year":2016}]

HTTP server routes information:

Verb	Path	Zone	Content type	MVC	View name	Roles
GET	/books	main	json
POST	/books	main	json
