creating controllers with akka-http easily

Supports the http verbs: @GET, @POST, @PUT, @DELETE. Also can handle json body or/and path params.

• akka-http-core
• akka-http-jackson
• java 1.8

1. Add maven dependency in your project:

   todo akka-http-ext-controller 0.0.l

2. Create controllers in your application:

public class UserController {

	@GET
	@Path("users/:id/details")
	public Route details(String id) {
		// getting pathParams
		return Directives.complete("Showing details for user " + id);
	}

	@POST
	@Path("users")
	public Route save(User user) {
		// parsing json body
		return Directives.complete("Saving user " + user.getName());
	}
}

3. Register your controllers with the Routes.init(ActorSystem, port, controllers...), as follows:

system = ActorSystem.create();
Routes.init(system, 8080, new UserController());

Please note that all controllers must be declared at once (In the same Routes.init call).

4. Done! You can access your controller at http://localhost:8080/users/1/details

All actions must have:

1. annotation to indicate the http verb
2. annotation @Path to indicate the path of action
3. return a akka.http.javadsl.server.Route object, usually you will use akka.http.javadsl.server.Directives for this.

using PathParams

When you use pathParams, the framework inject the arguments in the same order as received, for example: For @Path("user/:id/purchases/:purchaseId/items/:itemId/details") must have a controller with 3 String arguments like this public Route details(String id, String purchaseId, String itemId)

using JSON Body

When you use json body, the framework will try convert body content to object. An action in controller must receive a object, for example public Route update(User user). An error 500 will raise if parse fails.

using QueryString

TODO

$ mvn test

• add support to pathParams
• add support to json body
• add artifacts to the Central Repository
• add support to queryString
• add support to pathParams, json body and queryString when used in same time
• create annotation @Controller and make package scan to register controllers
• create annotation @Produces to use with custom content-types like application/vnd.api+json
