No Container: a Modern Java Stack with Bootique
The document discusses the evolution and advantages of using Bootique, a modern Java stack that allows for container-less application development. It highlights Bootique's capabilities for creating runnable web apps, microservices, and its integration with various modules while providing a history of its development. The author emphasizes the flexibility and minimal opinionation of Bootique compared to traditional Java EE and Spring Boot environments.
No Container: a Modern Java Stack with Bootique
- 1. No Container a ModernJava Stack with Bootique by Andrus Adamchik @andrus_a
- 2. About Me • Memberand VP of the Apache Software Foundation. • Run a company called ObjectStyle. • Develop open source technologies: ORM, dependency injection, REST, no-container.
- 3. –Anonymous Java Programmer “Iuse Java at work all the time, but I prefer Node.js for my own projects.” Java Paradox
- 4. Evolution of Java* •1998: Write a runnable app. • 2001: Write a container web app with JSP/EJB. • 2004: Write a container web app without JSP/EJB. • 2010: Write a container web app without web.xml. • 2016: Write a runnable web app without container. * Disclaimer: light sarcasm and oversimplification
- 5. Container Inversion • Appas an all-inclusive .jar. • Former container parts are included as libraries. • App is runnable and owns its main() method.
- 6. #WYSIWYR: What YouSee Is What You Run • Another way of saying "get off container and reclaim your main() method".
- 7. Bootique Minimally opinionated applauncher and integration technology.
- 8. Brief History • Firstcommit in December 2015. • Collaboration between ObjectStyle and National Hockey League. • Fully open-source under Apache License. • Successfully applied in complex enterprise environments.

- 17. Integration Technology forJava. WYSIWYR (apps are runnable). Requires container deployment. Can integrate any 3rd-party modules. Integrates a predefined set of specs. Unified config for all app parts. Container and apps are configured separately. Everything is programmable Container is somewhat programmable, but YMMV. Universal Java launcher Specialized opinionated environment.

- 19. Integration, WYSIWYR (appsare runnable), extension auto-loading, etc. Command dispatch feature. All available commands run sequentially. Guice DI Style: explicit modules, explicit overrides. Package-based implicit "modules". Annotations spread around. Features can't be turned on by accident. @Conditional built into the core. Unopinionated Core Opinionated
- 20. What Apps isit Good for? • Any web apps you used to write in the past, but also.... • Microservices. • Apps you distribute to users. • Cron jobs. • JavaFX apps. • Quick prototypes.
