Welcome to another installment of This Week in Spring! This week's roundup could've just as easily been titled, This Week in Spring Videos and Webinars, because we've got a lot of them!

1. The good Dr. Dave Syer continues his series introducing Spring Security and Angular.js integration, this time looking at breaking apart the resource server from the authorization server. This post looks
2. Our pal Nicoalas Frankel is back at it! Nicolas lives in both the Vaadin and the Spring communities. So, naturally, when Petter Holmström and I started the Vaadin4Spring project at the beginning of 2014, we weren't surprised when Nicolas started making great contributions. His latest contribution introduces an elegant implementation of the MVP pattern for Vaadin and he's written a very nice introduction to it…

Worried about Big Data and the challenges inherent in making a real application? You don’t have to worry anymore! Spring XD provides a one-stop shop solution that spans traditional enterprise to Big Data use cases - both batch and streaming. It's important to choose the right tool for each use-case, which is why Spring XD integrates with technologies such as Spark, Reactor and RxJava to demonstrate the flexibility and the unified programming model to support complex data computation use-cases. In this webinar, we'll show you how to develop data-driven use cases much faster than other big data solutions on the out of the box XD runtime.

Back in the era of the application server, HTTP Session replication was a common way to scale out user session data, as well as make it fault tolerant. In today's world of lightweight containers, PaaS, and virtualization, Spring Session offers a 100% server and/or container portable HTTP Session. See how Spring Session easily plugs in implementations like Redis, scales out across a cluster, handles multiple users' browser sessions, works with WebSocket, and allows header based authentication within REST apps. It's a perfect fit for working with user data, particularly in a highly distributed environment like the cloud, or on a Platform like Cloud Foundry.

An API's documentation is a vital part of making it easy to understand and easy to use. RESTful APIs are no different. In this webinar we'll look at what should be included in your RESTful API's documentation and, just as importantly, what should be omitted. To illustrate this we'll look at some real-world examples of good and bad API documentation. We'll look at some of the problems and limitations of choosing a tool like Swagger to produce your API's documentation and conclude by looking at some alternatives that are better-suited to producing documentation that your users will love.

Note: the source code and test for this blog continue to evolve, but the changes to the text are not being maintained here. Please see the tutorial version for the most up to date content.

In this article we continue our discussion of how to use Spring Security with Angular JS in a "single page application". Here we start by breaking out the "greeting" resource that we are using as the dynamic content in our application into a separate server, first as an unprotected resource, and then protected by an opaque token. This is the third in a series of articles, and you can catch up on the basic building blocks of the application or build it from scratch by reading the first article, or you can just go straight to the source code in Github, which is in two parts: one where the …

The microservice style of architecture is not so much about building individual services so much as it is making the interactions between services reliable and failure-tolerant. While the focus on these interactions is new, the need for that focus is not. We've long known that services don't operate in a vacuum. Even before cloud economics, we knew that - in a practical world - clients should be designed to be immune to service outages. The cloud makes it easy to think of capacity as ephemeral, fluid. The burden is on the client to manage this intrinsic complexity.

In this post, we'll look at how Spring Cloud helps you manage that complexity with a service registry like Eureka and Consul and client-side…

Web / JavaScript Track

The Web and Spring MVC continue to be one of the most active areas of the Spring Framework with each new release adding plenty of features and refinements requested by the community. Furthermore version 4 added a significant choice for web applications to build WebSocket-style architectures. This talk provides an overview of the areas in which the framework has evolved along with highlights of specific noteworthy features from the most recent releases.

Spring Data Cassandra brings Cassandra support to the Spring Data umbrella of projects, offering Spring Data's familiar Repository concepts & POJO persistence. This talk will focus first on POJO persistence over Cassandra, including automatic Cassandra schema generation and Spring context configuration using both XML & Java. Then, the talk will dig deeper into some of the lower-level features that Spring Data Cassandra is built upon (AKA "Spring CQL"), which make plain, old Cassandra development simpler & easier. Couchbase Server is well-known as one of the leaders in the NoSQL space, heavily used in enterprises and startups alike where low latency even at hundreds of thousands of operations per seconds matters. This talk will not only give a short introduction about the benefits of adopting Couchbase, but also show how to integrate it into your Java Enterprise landscape through its support for Spring Data. You will learn how to fully control your database schema from the application through entities and repositories, how to deploy new application versions or scale out your cluster without a single second of downtime and also how to integrate easily with elasticsearch.

Enterprise Integration Patterns, a set of software design concepts described in a book by Gregor Hohpe and Bobby Woolf and implemented in software by the Spring Integration project, are traditionally applied in the application domains such as business intelligence, supply chain management, and customer relationship management. The topic of this presentation is to describe an experimental methodology of applying Enterprise Integration Patterns to the near-real time processing of surveillance radar data and the engineering trade-offs encountered in the areas of development, deployment, operation, and analysis of ground-based surveillance radar systems with a focus on the Modular Experimental Radar program developed by MITRE for its sponsors.
