The age of artificial intelligence (because the search for regular intelligence hasn't gone well..) is nearly at hand, and it's everywhere! But is it in your application? It should be. AI is about integration, and here the Java and Spring communities come second to nobody.

In this talk, we'll demystify the concepts of modern day Artificial Intelligence and look at its integration with the white hot new Spring AI project, a framework that builds on the richness of Spring Boot to extend them to the wide world of AI engineering.

Spring Boot 3.x and Java 21 have arrived, making it an exciting time to be a Java developer! Join me, Josh Long (@starbuxman), as we dive into the future of Spring Boot with Java 21. Discover how to scale your applications and codebases effortlessly. We'll explore the robust Spring Boot ecosystem, featuring AI, modularity, seamless data access, and cutting-edge production optimizations like Project Loom's virtual threads, GraalVM, AppCDS, and more.

Let's explore the latest-and-greatest in Spring Boot to build faster, more scalable, more efficient, more modular, more secure, and more intelligent systems and services.

Hi, Spring fans! Developers today are being asked to deliver more with less time and build ever more efficient services, and Spring is ready to help you meet the demands. In this workshop, we'll take a roving tour of all things Spring, looking at fundamentals of the Spring component model, look at Spring Boot, and then see how to apply Spring in the context of batch processing, security, data processing, modular architecture, miroservices, messaging, AI, and so much more.

Alright, so maybe “bootiful” won't ever work, but I tried, and it was worth it too because you're reading this.

Spring Boot, the new convention-over-configuration centric framework from the Spring team at Pivotal, marries Spring's flexibility with conventional, common sense defaults to make application development not just fly, but pleasant! Join Spring developer advocate Josh Long (@starbuxman)
for a look at what Spring Boot is, why it's turning heads, why you should consider it for your next application (REST, web, batch, big-data, integration, whatever!) and how to get started.

In this talk, we'll look at Spring Cloud, which builds atop Spring Boot and the Netflix OSS stack, and see how it lets you easily integrate service-discovery, security, reliability patterns like the circuit breaker, and centralized and journaled property configuration (and more) into Spring-based services.

Join us for an in depth exploration of the Spring Cloud!

Using a module that provides a Spring XML namespace and integration API is muscle memory for most people: add the .xsd to the imported XML schemas for the configuration file, maybe enable a annotation-driven variant if it's available, autocomplete some XML stanzas, and then you're set! But what about Java configuration? Java configuration has been around in some form since at least 2005. It was merged into the core framework in 2009 and since then we've seen a slew of new Java configuration-powered DSLs pop up. 2013, in particular, has seen alpha-or-better cuts of Java configuration support for Spring MVC, Spring Security (and Spring Security OAuth), Spring Batch, Spring Social, Spring Data (including all the modules under it: REST, MongoDB, JPA, Neo4j, Redis, etc), Spring HATEOAS, and more all provide milestone-or-better cuts of a Java configuration integration. Tomcat 7 (and all Servlet 3-compatible containers) offer a programmatic alternative to web.xml. This provides another great integration hook for modules that wish to integrate with the web container, removing the configuration burden from the user. There's a lot of power here and it's easy to get started if you know what to look for. In this talk, join Spring Developer Advocate Josh Long and Spring-core commmitter, all-around nice guy, and Spring Boot ninja Phil Webb as they introduce the Java configuration support in the various Spring projects, show how to approach them when integrating them into your code, and - if the situation demands - how to write your own Java configuration DSL.

Session detail

This talk looks at how to move existing applications to a PaaS like Cloud Foundry or Heroku. This talk isn’t about building an application that’s optimized for the cloud, it’s about taking that first step with legacy applications. We’ll look at the things that tie existing applications to legacy platforms and how to loosen those bindings.

The goal here is to walk away with things that can be done quickly to get the application up and running in its new home among the clouds. We’ll look at how to break the reliance on JNDI, how to move distributed transactions with JTA, how to get reliable HTTP session replication (and then some!), how to retain security concerns and how to move to a much easier deployment model.

This talk looks at how to build applications taking advantage of Spring Boot’s operations features like the Spring Boot Actuator to gather metrics and counters about the state of the application.

In addition, you will learn how to tie it into reporting and monitoring systems like New Relic, and Graphite, and how to export information about the application using Crashub, REST, JMX, and more.
