SpringOne2GX 2014 Replay: Migrating to Spring 4 from Spring 3 - What you need to know

Migrating to Spring 4 from Spring 3 - What you need to know

Recorded at SpringOne2GX 2014.

Speaker: Phillip Verheyden

Applied Spring Track


In this talk we will cover what it takes to migrate a Spring 3.x application to Spring 4. Some of the questions that we will answer: What improvements does Spring 4 offer over Spring 3 and why should I invest in upgrading? What do I do with all of my current XML configuration? What about dependent library upgrades like Hibernate and Jackson? Part of this talk will focus on updating a specific application based on Spring 3 up to date with Spring 4 and the latest in best practices and design.

Webinar: Debug and Maintain your Spring Boot App

Speaker: Greg Turnquist

So you have decided to build an application using Spring Boot? Sooner or later, something will go wrong. It does not matter how experienced we are. How will Spring Boot help us figure out what went wrong and fix things? This talk introduces lots of tools to help us debug and manage "bootiful" apps. You will learn how to use Boot's autoconfiguration report, override Boot's settings & beans, create custom metrics/health checks/app info, and create custom JMX info & custom CRaSH commands.


SpringOne2GX 2014 Replay: Performance Testing Crash Course

Recorded at SpringOne2GX 2014.

Speaker: Dustin Whittle

Applied Spring Track


The performance of your application affects your business more than you might think. Top engineering organizations think of performance not as a nice-to-have, but as a crucial feature of their product. Those organizations understand that performance has a direct impact on user experience and, ultimately, their bottom line. Unfortunately, most engineering teams do not regularly test the performance and scalability of their infrastructure. Dustin Whittle shares the latest performance testing tools and insights into why your team should add performance testing to the development process. Learn how to evaluate performance and scalability on the server-side and the client-side with tools like Siege, Bees with Machine Guns, Google PageSpeed, WBench, and more. Take back an understanding of how to automate performance and load testing and evaluate the impact it has on performance and your business.


Webinar: Improving your (legacy) Application with Spring

Speakers: Marten Deinum

Spring has been around since the release of “J2EE Design and Development” in 2002. Spring and Java have evolved quite a bit since that time. In those years a lot of applications have been developed. All those "legacy" applications that are around have proven their value and that is why they lasted. In this session we will explore how we can improve our legacy applications by doing some refactoring or redesign (component based development) but also by introducing (newer) Spring IO technologies.
