欢迎回到 2011 年Spring 本周的最后一期。 难以置信，我们已经做了一年了！时间都去哪儿了？ 正如他们所说，当您玩得开心时，时间过得真快...

一直以来的希望是，这些综述将使开发人员更容易了解 Spring 社区的脉搏。 在 SpringSource 和 VMware 的公告、发布和内容以及社区撰写的令人难以置信的大量内容之间，总有有趣的事情发生。

虽然本周有很多有趣的内容，但我们将把通常的评论推迟到下周。 本周，我们将反思 2011 年 Spring 社区的情况。

	<lI>  <B>Spring 3.1</B> Development of Spring 3.1 began in earnest in early 2010, and by SpringOne 2GX 2010 we already had an idea of what it was going to look like. By the beginning of this year, <a href ="http://www.springsource.org/node/3026">we already had milestones</a> to play with.  
  As the year progressed, we saw numerous new milestones, followed in short order by release candidates. The release candidates progressed and then, finally, a couple of weeks ago, we <a href = "http://www.springsource.org/node/3335">got Spring 3.1 GA</a>. 

在 Spring 3.1 中众多新的、令人兴奋的功能和主题中，有

• 显著改进的 Java 配置模型
• 针对 JPA 和 Spring MVC 应用程序的增强的纯 Java 配置。
• 配置文件，它允许您在配置中描述 bean 两次，然后根据应用程序运行的环境激活给定的定义。
• 一个 Environment 抽象
• 一个 声明式、注解驱动的缓存模型
• 一个改进的 单元测试案例
• Hibernate 4 支持

		<B>The Cloud and Cloud Foundry</B> 
		
		 In April of this year, <a href ="http://blog.springsource.org/2011/04/12/launching-cloud-foundry/">SpringSource and VMWare launched   Cloud Foundry</A>, the open source Platform as a Service. <a href = "http://cloudfoundry.org">Cloud Foundry</a> can be run on-premise. 
		
		Cloud Foundry is an open-source Platform-as-a-Service (PaaS). Cloud Foundry works with many languages, runtimes, and services. And, if the list of supported services and runtimes wasn't enough, one only had to wait to see <a href="http://blog.cloudfoundry.com/post/6109591023/cloud-foundry-now-supporting-scala"> Scala</a> support, <a href ="http://blog.springsource.org/2011/08/30/using-postgres-on-cloud-foundry/">PostgreSQL</a> support, <a href = "http://blog.springsource.org/2010/04/13/springsource-acquires-rabbitmq/">RabbitMQ</a> support and <A href = "http://blog.cloudfoundry.com/post/13481010480/cloud-foundry-welcomes-net-framework-community-contributions">.NET</a> support added in the months that followed.
		
	 
			Cloud Foundry works <a href = "http://blog.springsource.org/2011/10/13/using-cloud-foundry-services-with-spring-part-1-the-basics/">brilliantly</a> with <a href ="http://blog.springsource.org/2011/11/04/using-cloud-foundry-services-with-spring-part-2-auto-reconfiguration/">Spring applications</a>.
			
			 You can use the <a href = "http://blog.springsource.org/2011/11/09/using-cloud-foundry-services-with-spring-applications-part-3-the-cloud-namespace/"> &lt;<CODE>cloud</CODE>&gt;</a> namespace or Java configuration in tandem with the Cloud Foundry library to interrogate and work with the services provisioned by Cloud Foundry. <a href ="http://blog.springsource.org/2011/11/10/using-cloud-foundry-services-with-spring-part-4-%e2%80%93-spring-profiles/">Spring 3.1 profiles can be used to to good effect on Cloud Foundry</a> to conditionally reference data sources that are managed  by the cloud when your application's run in the cloud. Spring AMQP and Spring Integration make  it simple <a href = "http://blog.springsource.org/2011/08/16/chatting-in-the-cloud-part-1/">to build messaging applications using RabbitMQ</a> on Cloud Foundry, and the Spring Data projects make it dead simple to build applications that work with <a href = "http://blog.springsource.org/2011/05/03/using-mongodb-redis-node-js-and-spring-mvc-in-a-single-cloud-foundry-application/"> MongoDB, and  Redis</a> on Cloud Foundry. There is of course <a href = "http://blog.springsource.org/2011/08/24/using-micro-cloud-foundry-from-grails/">Grails support</a> and <a href ="http://blog.springsource.org/2011/04/12/roo-cloud-foundry-productivity-in-the-cloud/">Spring Roo support</a>. <a href = "http://blog.springsource.org/2011/08/24/micro-cloud-foundry-for-spring-developers/"> Cloud Foundry released Micro Cloud Foundry</a>, a virtual machine with a fully configured cloud that you could use to develop your Spring applications locally. To support automated builds with Cloud Foundry, <a href="http://blog.springsource.org/2011/09/22/rapid-cloud-foundry-deployments-with-maven/">developers can use the Maven plugin</a>.

	<LI> <B>Big Data</B> 
		2011 delivered the implementation of the NoSQL data integration vision that Rod Johnson described way back at SpringOne 2GX 2010. 
		
   This year saw  many Spring Data projects reach or exceed 1.0 releases (and the numerous milestones and release candidates that precede GA releases!), including  <a href = "http://blog.springsource.org/2011/02/10/getting-started-with-spring-data-jpa/">Spring Data JPA</a> and  <a href = "http://www.springsource.org/node/3302">Spring Data Neo4J</a>, <a href  = "http://www.springsource.org/node/3346">Spring Data MongoDB</a>, <a href ="http://www.springsource.org/node/3337">Spring Data Redis</a>, <a href = "http://www.springsource.org/node/3336">Spring Data GemFire</a>, and the evolution of numerous other interesting projects like <a href = "https://github.com/SpringSource/spring-hadoop">Spring Hadoop</a>, and the concept of <a href = "http://blog.springsource.org/2011/07/27/fine-tuning-spring-data-repositories/">Spring Data Repositories</a>.

	<LI>  <B>Mobile and The Next Generation Web </B>  
		
		 The web's a big place, and it comes in many form factors.  
	
	Today, delivering an application means delivering it  through the web, and on  mobile platforms like Android and iOS. 
		
		A huge  part of building better mobile applications is building  RESTful services for  communication between client and a server in a standard, interoperable way.
		
		

Spring Core 提供了 RestTemplate，它有助于客户端和服务器之间的 RESTful 通信。

Spring Android 提供从 Android 设备使用 RESTful Web 服务的支持。

This year even saw the creation of some great information for <a href = "http://blog.springsource.org/2011/08/26/clean-code-with-android/"> building cleaner Android applications overall</a>. 		
 

As powerful as REST is, it can't be the full story. A critical piece of the pie is security, and authorization. After all,  Facebook can't very well go around exposing your data through a RESTful service that you haven't explicitly authorized it to. The last few years bore witness to the rise of the various OAuth standards, and implementations by the various 	service providers like Facebook, Twitter, etc. <a href = "http://blog.springsource.com/2011/09/08/spring-social-1-0-what-a-year-makes/">Spring Social went GA this year</a> and it supports communication with these services through OAuth. Spring Android also supports Spring Social, making it ideally trivial to consume OAuth-secured, RESTful services from

Android 应用程序。 此外，Spring Security OAuth，一个专门用于帮助人们使用 OAuth 公开安全服务的 Spring Security 项目，今年也开始了 GA 之路。
