I'm super excited to announce the first milestone release of Project Reactor! Project Reactor is a foundational framework for building asynchronous, FastData applications on the JVM. Some of the goodness in Reactor 1.0.0.M1 includes: reactive composition helpers Stream and Promise, a TcpServer and TcpClient, and Groovy and Spring support. Inspired by Reactive Extenstions, RxJava, the new JDK 8 Stream API (and Scala, and others...), these Composables make coordinating asynchronous tasks dead simple. They support traditional callback-style programming using Consumers, but they also offer a…

Welcome back to another installation of This Week in Spring. We've got a lot to cover, as usual, so let's get right to it! This week I'm at SenchaCon, talking to developers about building RESTful applications and clients, and then I'm off to OSCON next week, where I'll be hosting the Spring BOF, giving a talk on the latest and greatest in Spring 4, and helping to man the Pivotal booth. If you're at SenchaCon or OSCON, don't hesitate to ping me and we can talk Spring, Cloud Foundry, big-data, and more!

Are you an Eclipse user? Do you want a fast and easy way to search for text snippets and patterns in your workspace? Then read on!

A new "Quick Search" is included in Spring ToolSuite (STS) 3.3.0 and Groovy Gails Tool Suite (GGTS) 3.3.0 which have just been released. Even if you are not a Spring or Grails developer, you might be interested in this Feature because it can also be installed separately into a vanilla Eclipse.

Introducing the Quick Search Dialog

You open the dialog by pressing CTRL+SHIFT+L (or CMD+SHIFT+L on Mac):

The Power of Simplicity

Of course you can also use the mouse if you want to, but there's no need for your hands to leave the keyboard…

In this post, I will discuss how to make your Spring Security Java configuration more readable. The post is intended to elaborate on a point from Spring Security Java Config Preview: Web Security where I stated:

By formatting our Java configuration code it is much easier to read. It can be read similar to the XML namespace equivalent where "and()" represents optionally closing an XML element.

Indentation

The indentation of Spring Security's Java configuration really impacts its readability. In general, indentation like a bullet list should be preferred.

For a more concrete example, take a…

Welcome to another installment of This Week in Spring. There's a lot of good stuff this week, including content on Apache Tomcat, Spring Security's new Java configuration updates, Spring Batch's Java configuration support, and so much more! We're fast approaching the August price increase for SpringOne2GX 2013 so register now and lock in the lower rate. Ok -- Let's get to it!

1. Craig Walls has announced that Spring Social 1.1.0.M3 (including revs to Spring Social, Spring Social Facebook, and Spring Social Twitter) is now available. The new release has a lot of compelling features including a new ReconnectFilter, support for OAuth 2's 'state' parameter to prevent CSRF attacks, and initial support for Twitter's streaming API.
2. Spring Security lead Rob Winch never sleeps. Also, he's just put together several very interesting posts on the brand new Spring Security Java configuration support. He starts the series with an introductory post. The second post covers the details of method-level security (fine-grained access control at the level of individual method invocations). The third post covers the details of web-based security (intercepting HTTP requests). The last post looks at how to use Java configuration to configure Spring Security OAuth. These posts are definitely worth a read! If you love these posts as much as I do, would you please upvote them on DZone?
3. Have you guys been following Spring XD's development? It's really coming along nicely! One thing that caught my eye recently? The amazing Andy Clement, designer and implementer of the amazing Spring Expression Language (SpEL), and a major contributor to the amazing tooling in the Spring Tool Suite and Grails Tool Suite, is now putting his amazing talents to work building a DSL for Spring XD jobs. To learn more, and to feedback on use cases that might be valuable to you, check out the JIRA.
4. Upcoming Webinar: Join Mattias Severson & Johan Haleby on July 18th for a talk on Functional Programming without Lambdas.
5. Upcoming Webinar: Join Hemant Joshi on July 30th for a talk on Spring with Cucumber for Automation.

7. Petri Kainulainen is back at it, this time with a post on to unit test regular Spring MVC @Controllers.
8. News for Groovy & Grails, SpringSource changed the 3-day class to a new 4-day developer class. The first opportunity to attend will be Groovy & Grails in San Francisco.
9. Tobias Flohre is back at it again! The last two parts of his awesome series Spring Batch Java Configuration are available. The first post has to do with modular configuration with Java configuration. The second post has to do with job partitioning and multi-threaded steps
10. Apache Tomcat ninja Mark Thomas has announced the release of Apache Tomcat 7.0.42, which contains a number of bug fixes and improvements compared to version 7.0.41.
11. Stuart Williams (or @pidster, to those who know him) has recently put together a nice Spring Shell-powered console for working with MQTT messaging systems. Spring Integration also features nice support for MQTT in the Spring Integration Extensions repository.
12. Speaking of Apache Tomcat, did you guys see Mark Thomas' presentation introducing some of the upcoming Apache Tomcat 8 from last year?

This is the fourth post in my five part blog series that introduces Spring Security Java configuration. In this post, we will discuss how Spring Security Java configuration can be extended by walking through Spring Security OAuth Java configuration support.

Proof of Concept

While the Spring Security Java configuration works well for very basic configuration, it is just a proof of concept. We have not ensured that all the functionality available in the XML namespace is present within its Java configuration support. It was important to ensure that Spring Security's Java configuration would work…

Update

Users should refer to the Spring Security Reference which contains more up to date information.

Original Blog Post

This is the third installment of a four part blog series. In my first post, I introduced Spring Security Java configuration and discussed some of the logistics of the project. In my previous post, we walked through a few examples of configuring web based security.

In this post, I will discuss how to configure method based security using Spring Security Java configuration. Like our previous post, we will start off with a very basic example and follow it up with an example…

Welcome to another installment of This Week in Spring! As usual, we've got a lot to cover so let's get to it!

1. Spring and Cloud Foundry ninja Jennifer Hickey has announced the availability of Spring Data Redis 1.1 M1 and 1.0.5. Check it out!
2. Spring Security lead (and ninja) Rob Winch has announced the initial availability of the Spring Security Java configuration support. Rob also just posted a very nice post (the first of four) on the new Spring Security Java configuration support. The first post addresses where you can find the new Spring Security Java configuration support.
3. Join us on July 18th for the webinar, "Functional Programming without Lambas" which introduces ways to use functional programing in Java right now (instead of waiting for Java 8!) using Guava, LambaJ, and Functional Java.
4. Corby Page has written a very nice post on ways to extend your REST APIs ability with his project, Yoga. In particular, it supports something called a selector which can be used to extract sub-views of the REST response to be sent back to the client. This can also be used to support what Lez Hazelwood aptly describes as entity expansions.
5. The Crunchify blog has a nice post on how to upload multiple files with Spring MVC.
   
6. SpringSource has added a new Live Online Core Spring class to the schedule for September .
   
7. The Spring LDAP project has gone social and moved to GitHub!
8. Our pal XueFeng Ding (who you may remember helped put together the blog "Spring at China Scala") has just recently given a very nice presentation on building REST APIs with Spring. I think his deck's pretty cool, so check it out!
9. Sergey Shcherbakov recently gave a nice talk introducing a whole slew of cool things. I think his sample code is particularly worth a look. The code features Spring 4 WebSockets, XML-less Spring Batch, Reactor and AngularJS examples. Nice job, Sergey!
10. Johnathan Mark Smith has put together a nice blog on how to use Spring Data with MongoDB. Nice job!
11. Nicolas Frankel has put together a very nice post on some of the compelling features in Spring 3.2. Nice job, Nicolas!
12. Nick Williams submitted a pull-request to support using Java configuration with Spring WS's MessageDispatcherServlet so that it can be configured within a ServletContextListener or a ServletContainerInitializer. Nice job, Nick!
13. This is not specific to Spring, or Spring Batch, per-se, but the Technology AMIS blog has an interesting look at how to use the Batch JSR (which is based on Spring Batch, and designed in cooperation with the Spring Batch team) to build a download manager. (Don't worry, you don't have to use GlassFish to work with the Batch JSR!) Pretty cool! If you know Spring Batch, then a lot of this will look familiar and, as Spring Batch will also implement the JSR, should prove a very nice on-ramp for anyone who wants to use Spring Batch in the future.

Original Blog Post

In my previous post, I introduced Spring Security Java configuration and discussed some of the logistics of the project. In this post, we will start off by walking through a very simple web security configuration. We will then spice things up a bit with configuration that has been customized some.

Hello Web Security

In this section we go through the most basic configuration for web based security. It can be broken into four steps:

• Updating your dependencies - we demonstrated this using Maven in our previous blog post
• Provide the Spring Security configuration - in our example this is done with a WebSecurityConfigurerAdapter
• Ensure the Spring Security configuration is loaded - in our example this is done with AbstractAnnotationConfigDispatcherServletInitializer
• Configure the springSecurityFilterChain - in our example this is done with AbstractSecurityWebApplicationInitializer
