{8.0.0-new} Overview

The Juneau integration component for Spring Boot consists of the following classes:

- {@link oajr.springboot.annotation.JuneauRestRoot}
- {@link oajr.springboot.JuneauRestInitializer}
- {@link oajr.springboot.SpringRestResourceResolver}

A typical Spring Boot application can use the {@link oajr.springboot.JuneauRestInitializer} to find and register Juneau REST servlets via the {@link oajr.springboot.annotation.JuneauRestRoot} annotation.

##### Example:

@SpringBootApplication @Controller public class App { public static void main(String[] args) { new SpringApplicationBuilder(App.class) .initializers(new JuneauRestInitializer(App.class)) .run(args); } /** Our root resource */ @Bean @JuneauRestRoot public RootResource getRootResource() { return new RootResource(); // A subclass of RestServlet. } }

The initializer will search for Spring beans annotated with the @JuneauRestRoot annotation identifying it as a top-level servlet to be deployed in the Spring Boot web container.

Another option is to use the @JuneauRestRoot annotation on your Spring Boot source class like so:

@SpringBootApplication @Controller @JuneauRestRoot(servlets=RootResource.class) public class App { public static void main(String[] args) { new SpringApplicationBuilder(App.class) .initializers(new JuneauRestInitializer(App.class)) .run(args); } }

The root servlets are given an instance of {@link oajr.springboot.SpringRestResourceResolver} which allows for child resources to be defined as injectable Spring beans.

The {@doc juneau-examples-rest-springboot} section describes how the Examples REST application is deployed using Spring Boot and quickly deployable as an online application using Heroku.
