Webinar: Building a Shopping Cart in 24 Hours using Spring

News | Pieter Humphrey | June 10, 2014 | ...

Speakers: Casey Doolittle and Phil Dutson, ICON Health & Fitness

Creating a transactional website that is secure, fast, and responsive is a challenge all on its own. Creating one in 24 hours borders madness, however with the resources that Spring brings to the table, this can be accomplished. Casey Doolittle and Phil Dutson were issued the task of creating a charity-benefit website two days before the sale started. By leveraging the flexibility and power that various Spring components bring to the table, this mighty feat was accomplished. During this talk Casey and Phil will discuss the how and why of using Spring 3.2.4, Spring Web MVC, and Spring Security 3.1.4 as their framework of choice to get the project done on time.

Pivotal Disclaimer: These are not Pivotal employees, nor is this a "best practices" session or represent Pivotal recommendations. This is an great story of how 2 guys used the tools they already knew to respond to a ridiculous requirement!

SpringOne2GX 2013 Replay: Space Exploration: APIs for Secure Interconnected HTML5 Applications with Sencha Space

News | Pieter Humphrey | June 10, 2014 | ...

Recorded at SpringOne2GX 2013 in Santa Clara, CA

Speaker: Jason Cline

The proliferation of mobile devices poses challenges for corporate IT departments. End users want to choose their own device, but also want to access corporate web applications, but the need for security often means that they have to surrender management of their device to their IT department. With this in mind, we've created Sencha Space -- a secure and managed environment for deploying HTML5 business applications that run on multiple devices. During this session Jason Cline will discuss the Sencha Space SDK's device-level options for secure data storage, as well as show you how to implement the Invoke API to connect web applications with one another. You'll also experience how easily applications can be centrally managed without the need to access the device.

SpringOne2GX 2013 Replay: Making Connections with Spring Social

News | Pieter Humphrey | June 10, 2014 | ...

Recorded at SpringOne2GX 2013 in Santa Clara, CA

Speaker: Craig Walls

The modern web is rich with APIs that can be consumed by other applications, enabling an integrated experience for the users who hold accounts on the websites that front those APIs. Many of these APIs are secured with OAuth, an authorization specification for securing REST APIs. Spring Social is an extension to the Spring Framework that enables Spring applications to establish connections with those APIs on behalf of their users with little or no need to muck about in the intricacies of OAuth. In this session, we'll explore how Spring Social brings API connectivity to Spring applications. We'll also uncover the newest features of Spring Social that make it easier than ever to link your application's users to the identities they maintain on various sites across the web.

We were able to merge all of his commits into an independent repository, apply some editorial polish, and after final review…

Webinar Replay: Abstracting PaaS services to be portable with Spring Cloud

News | Pieter Humphrey | June 04, 2014 | ...

Speaker: Ramnivas Laddad

Slides: https://speakerdeck.com/ramnivas/abstracting-paas-services-to-be-portable-with-spring-cloud

Developing an application to a cloud platform involves working with deployed application's environment and connecting to services. Spring Cloud, a new project, simplifies these tasks in a variety of cloud platforms including Cloud Foundry and Heroku. Spring Cloud makes it possible to deploy the same artifact (a war or a jar) to multiple cloud environments. It supports multiple clouds through the concept of Cloud Connector and provides out of the box implementation for Cloud Foundry and Heroku, and extension points for other cloud platforms. In this talk, we will introduce the Spring Cloud project, show how you can simplify configuring applications for cloud deployment, discuss its extensibility mechanism, and put it to good use by showing practical examples from the field.

This Week in Spring - June 3rd, 2014

Engineering | Josh Long | June 03, 2014 | ...

Welcome to another installment of This Week in Spring. This week's an exciting week! Well, let's be honest. They're all exciting weeks. But in particular, this week's going to make a lot of people happy. Watch the blog and I'll see you back here next week to recap! :)

  1. Oh my goodness! Spring Boot 1.1.0.RC1 is now available! The new release maintains the epic with support for Spring Data Elasticsearch, HornetQ, and Spring Social, and a lot more! Grab the latest release, kick the tires, and feedback on Twitter or GitHub.
  2. Dr. Mark Pollack has just announced that the latest release of Spring XD, 1.0.0.M7 is now available. The new release provides a lot of great new features. My favorite is the ability to pin data to a certain stream - think of this as correllation using a message's content - so that you can preserve stateful operations. Think of this as a great way to route and divide messages based on a useful business key. There's a great example in the release notes.
  3. Azul rockstar Gil Tene gave an amazing talk on reducing latency for SpringOne2gX 2013 that is now available online. Gil is one of our industry's mad scientists. I haven't yet seen this talk, but I will, and I highly recommend that you do too. Azul makes high performance, low latency JVMs both as appliances and as deliverable software. His talks thus stem from a lot of thankless research and development that I'd just as soon spare myself by watching, and learning from, his talks. Go, Gil!
  4. June webinars are here! Michael Minella in Spring Batch 3.0.0 on June 10th, and Glenn Renfro in Spring Integration Done Boot-ifully on June 17th.
  5. Spring ninja Greg Turnquist has put together a teaser post on using the amazing when.js Promises/A+ implementation in a front-end REST client in advance of his SpringOne2GX 2014 talk. Check out the post and his talk at the conference!
  6. Ramnivas Laddad, a Spring ninja, original AspectJ leaders, and architects behind Cloud Foundry, has just posted a very cool look at Spring Cloud, which makes consuming client services from different middle/infrastructure services (a database, a message queue) on various Platforms-as-a-Service (PaaSes) a simple matter of platform-decoupling configuration.
  7. The replay of ADP's Jeffery Sologov's talk looking at the pitfalls of building large scale applications is now up! Check it out!
  8. ttp://twitter.com/JakubJirutka chimed in to tell us about this epic Spring Expression Language (SpEL)-powered implementation of the Bean Validation API (JSR 303/349). The GitHub offers an interesting point, "it’s especially very useful for cross-field validations that are very complicated with a plain Bean Validation." I love the examples, too:
    @SpELAssert(value = "password.equals(passwordVerify)",
            applyIf = "password || passwordVerify",
            message = "{validator.passwords_not_same}")
    public class User {
      private String password;
      private String passwordVerify;

    Nice job!

  9. A hat tip to the amazing Brian Dussault for finding this: Zuul is a nifty looking application configuration management solution that offers a clean Spring client API.

  10. You know what made my day yesterday? A HystrixInvocationHandler. An InvocationHandler is used by the JDK (and Spring's rich proxying subsystem) to create proxies that wrap beans. This InvocationHandler wraps method invocations on a given bean in Netflix's OSS Hystrix project's Command objects. Hystrix Commands wrap functionality and provide/support resiliency patterns. I can't wait to see more of what becomes of Spencer Gibb's Halfpipe project!
  11. Our pal David Welch is at it again, this time with an interesting project called Spring Tiered, which aims to simplify even further (and normalize) the development of HATEOAS based services. Interesting...
  12. Also, speaking of building (and consuming) resilient services, check out Chris Richardson's fantastic talk from SpringOne2GX 2013 on powerful abstractions for consuming services asynchronously.
  13. Also, I put together a post talking about getting started with Maven (and alternatives) and Spring

Spring XD 1.0.0.M7 Released

Releases | Mark Pollack | June 03, 2014 | ...

The Spring XD team is pleased to announce that Spring XD Milestone 7 is now available for download.

Highlights of this release

  • Transport Data Partitioning: By default, messages are delivered to multiple instances of a stream module in a round-robin manner. However, if a module performs operations such that it can not consume random messages from the stream, then you can partition the stream based on its content so that similar messages are always delivered to the same module instance. For example, if a processing module is performing stateful operations on a per-customer basis, the stream…

SpringOne2GX 2013 Replay: How Not to Measure Latency

News | Pieter Humphrey | June 03, 2014 | ...

Recorded at SpringOne2GX 2013 in Santa Clara, CA

Speaker: Gil Tene, Azul

Time is Money. Understanding application responsiveness and latency is critical not only for delivering good application behavior. It is critical for maintaining profitability and containing risk. But good characterization of bad data is useless. When measurements of response time present false or misleading latency information, even the best analysis can lead to wrong operational decisions and poor application experience. In this presentation, Gil Tene (CTO, Azul Systems) discusses some common pitfalls encountered in measuring and characterizing latency. Gil demonstrates and discusses some false assumptions and measurement techniques that lead to dramatically incorrect reporting results, and covers simple ways to sanity check and correct these situations. He discusses the fallacy of using standard deviation measurements, the strongly multi-modal nature of latency, common discontinuities found in most computing platforms, and how back pressure and coordinated data omission issues can literally skew measurement results by orders of magnitude. Gil introduces and demonstrates how simple and recently open sourced tools can be used to improve and gain higher confidence in both latency measurement and reporting.
