Device aware view management is very useful specially when it is required to serve different optimized versions of same website based on request generating device type or specific devices.
Another feature called site preference management allows user to set his / her preference (SitePreference) to view a particular site in either "normal", "mobile" or "tablet" mode from a particular device.
Spring mobile also provides different types of site switchers (like mDot, dotMobi and urlPath SiteSwitcher) which automatically redirect users to the device specific site based on the device generating the request and site preference set by the user.

In this post, we'll see how to get started with a Spring Web model-view-controller (MVC) framework based Hello World web application in few steps. Here, we have used m2e-wtp (Maven Integration for Eclipse WTP) to generate a web project, Eclipse IDE to develop the code and Tomcat Server 7 to deploy and run the web application which will print 'Hello World!' in the browser.

Here we'll see two examples - Copy operation & Traversing a file tree. If you have already worked using JDk 6 or earlier versions then you can see how easy it is to use JDK 7's nio package. And you need to write less code to implement the same.

Spring AOP uses either JDK dynamic proxies or CGLIB to create the proxy for a given target object. If the target object to be proxied, does not implement any interfaces then a CGLIB proxy will be created. In this situation if CGLIB is not present in the classpath following exception will be thrown

org.springframework.aop.framework.AopConfigException: Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.
