This document discusses how to develop Java projects in a fast, trendy way for hipsters. It proposes using project generators like Yeoman to quickly create project structures and boilerplate code. Lombok is recommended to reduce boilerplate code through annotations. The document also discusses implementing microservices using the Netflix OSS stack for service discovery, load balancing, and other capabilities. Example microservice architectures like that of McDonalds are provided.

- 1. Hack `n` Tell “Java for Hipsters: how to develop fast, cool and in trendy manner” A
- 2. Generic hipster portrait: - Like trendy stuff - Watches TV series from Netflix - Loves Muffins - Dislike to work hard - Uses twitter Intro
- 3. Agenda - how to be fast - project kickstarters - code generation - microservices & tools - spring components - microservices tools - demo
- 4. Campaign proposal Project & code generation: Create each time - mvn folder structure - pom.xml | gradle.build - web.xml, myapp-servlet.xml, - MyAppApplication.class - etc IS TOO BORING! Lets kickstart project with generator!
- 5. Campaign proposal What's Yeoman? Yeoman helps you to kickstart new projects, prescribing best practices and tools to help you stay productive. Generators are available for Angular, Java, Backbone, React, Polymer and over 3900+ other projects. Project generation
- 6. Campaign proposal Technology stack on the client side HTML5 Boilerplate Twitter Bootstrap AngularJS Sass installation - Bower Build - Gulp.js Testing - Karma and PhantomJS template engine - Thymeleaf Technology stack on the server side Spring Boot Maven or Gradle "development" and "production" profiles Spring Security Spring MVC REST + Jackson WebSocket support with Spring Websocket Spring Data JPA + Bean Validation Database updates with Liquibase Elasticsearch MongoDB Cassandra Monitoring with Metrics Project generation
- 7. Code generation Lombok project Bolerplate code – the biggest evil in Java @NonNull @Cleanup @Getter / @Setter @ToString @EqualsAndHashCod e @NoArgsConstructor, @AllArgsConstructor @Data @Value @Builder @SneakyThrows @Synchronized @Log @Slf4j @Log4j @CommonsLog
- 9. Campaign proposal Microservices with Spring and Netflix OSS
- 11. microservice topology or how much services should I have?
- 12. Main challenges: - Service discovery - Load balancing - Config management - Circuit brake - Health monitoring
