During 2011, Oracle introduced the SPARC Super Cluster T4-4, a general-purpose, engineered system with Oracle Solaris that delivered record-breaking performance on a series of enterprise benchmarks.Oracle's SPARC-based systems are some of the most scalable, reliable, and secure products available today.

After sifting through catalogs of library photos of the devastation of San Francisco’s 1906 earthquake, I picked out a variety of photos taken from April 18, 1906 to 1907 that I felt give a well-rounded depiction of what was going on in the city at the time. I found that many of the original photos I planned to use were in fact unusable because the photographer was situated in a place where a building stands today.
In this post we will write a CRUD Restful Web Service using Spring MVC 4, and write a REST client with Rest Template to consume those services. It’s an is an architectural style which can be used to design web services, that can be consumed from a variety of clients. Under the hood, @Rest Controller is itself annotated with @Response Body, and can be considered as combination of @Controller and @Response Body.
Of course sometime we do need to adapt our API/application as well.
For instance, if we want to serve XML as well, we should annotate User class with proper JAXB annoations. Retrieve Single User Specify a GET with /user/1 , click on send.
We will also test those services using external clients. The core idea is that, rather than using complex mechanisms such as CORBA, RPC or SOAP to connect between machines, simple HTTP is used to make calls among them. @Request Body : If a method parameter is annotated with @Request Body, Spring will bind the incoming HTTP request body(for the URL mentioned in @Request Mapping for that method) to that parameter.
In Rest based design, resources are being manipulated using a common set of verbs. While doing that, Spring will [behind the scenes] use HTTP Message converters to convert the HTTP request body into domain object [deserialize request body to domain object], based on ACCEPT or Content-Type header present in request.
This Stack Overflow link is a must read to understand REST in detail. As already mentioned, in Spring 4, you may stop using this annotation. @Path Variable This annotation indicates that a method parameter should be bound to a URI template variable [the one in ''].
Following is one possible Rest based controller, implementing REST API. Basically, @Rest Controller , @Request Body, Response Entity & @Path Variable are all you need to know to implement a REST API in Spring 4.
