Dear Spring community,

I'm pleased to announce that Spring Framework 4.1.1 is available now. As the first maintenance release in the 4.1 line, this release contains a wide range of fixes for regressions and other issues reported against 4.1 GA. A big thank you to all the issue reporters out there!

4.1.1 also comes with a selection of minor enhancements, for example: consistent handling of Java 8's Optional type, a Jackson ObjectMapper builder class with refined defaults, some requested JDBC refinements, as well as specific performance improvements.

Today's applications are complex, distributed systems that - taken together - produce results. Tracking the flow of work through that system, however, becomes increasingly more painful as automated- and human-driven tasks are integrated into business processes. Business can't react to what it can't see. Business can't measure what it can't see. "Workflow" describes the sequence of processes through which a piece of work passes from initiation to completion. Workflow systems, like Activiti, describe and then execute these processes. Activiti is an open-source, Apache 2-licensed workflow engine that works with Spring and Spring Boot. In this webinar, join Spring Developer Advocate Josh Long and Activiti-ninja Joram Barrez for a look at how to distill, describe and reuse complex business processes using Spring (and Spring Boot) and Activiti.

Speaker: Michael Plod

Slides: https://speakerdeck.com/mploed/pivotal-webinar-why-do-i-recommend-spring

Is Spring the new legacy as quite a few people tell you on their blogs? I disagree on many levels. Throughout this session I will holistically detail without any polemics why I do recommend using the Spring Framework and its ecosystem. Aspects that will be covered include: operational impacts, ecosystem, coding and road maps. This presentation is aimed at IT managers, Architects and Developers alike.

Speaker: Derek Beauregard Contributors: Phil Berman, Darrel Sharpe, Michael Minella In this demo we will explore the power of Spring XD in the context of the Internet of Things (IoT). We will look at a solution developed with Spring XD to stream real time analytics from a moving car using open standards. Ingestion of the real time data (location, speed, engine diagnostics, etc), analyzing it to provide highly accurate MPG and vehicle range prediction, as well as providing real time dashboards will all be covered. Watch this demo to get a sense of how Spring XD can serve as a critical…

Welcome to another installment of This Week in Spring! This morning, I had the joy of presenting with my pal Joram Barrez on using the Activiti BPMN workflow engine with Spring (and Spring Boot). That talk should be online in the next few weeks or so. I'll also be co-presenting with Joram this week at the Alfresco Summit (on the very same topic). If you missed SpringOne2GX 2014, check out the Day 1 and Day 2 wrap ups where can learn about NetFlix, Spring Boot and microservice architecture, among many other things.

1. The replay of the webinar talk that I gave last week, Bootiful Microservices with Spring Boot (and Spring Cloud), is now available online. This talk - because of Boot and the subject matter - got a lot of attention and so this was actually available online within a few days (not the usual week or two) of my having presented it! Enjoy!

Speaker: Josh Long

Slides: https://speakerdeck.com/joshlong/building-bootiful-microservices-with-spring-boot

Microservices? A thing? Or hype? What does it mean in practice? The answer, like so many Facebook statuses, is complicated. In broad strokes, Microservices offer a refreshed approach to application architecture. Microservices are a new way to describe many of the patterns that have fallen out of large-scale applications in practice over the recent years. There is no doubt that the approach works. The question is: how does one build a microservice architecture? Join Josh Long for this webinar introducing Spring's support for building microservice architectures, including both Spring Boot, and the new Spring Cloud project.

Introduction

In my previous post, I discussed Spring Security WebSocket integration. One of the problems is that in a servlet container, the WebSocket requests do not keep the HttpSession alive.

Consider an email application that does much of its work through HTTP requests. However, there is also a chat application embedded within it that works over WebSocket APIs. If a user is actively chatting with someone, we should not timeout the HttpSession since this would be pretty poor user experience. However, this is exactly what JSR-356 does.

Another issue is that according to JSR-356 if the HttpSession times out any WebSocket that was created with that HttpSession and an authenticated user should be forcibly closed. This means that if we are actively chatting in our application and are not using the HttpSession…
