Spring Essentials

Overview of this book

Spring is an open source Java application development framework to build and deploy systems and applications that run on the JVM. It is the industry standard and the most popular framework among Java developers with over two-thirds of developers using it. Spring Essentials makes learning Spring so much quicker and easier with the help of illustrations and practical examples. Starting from the core concepts of features such as inversion of Control Container and BeanFactory, we move on to a detailed look at aspect-oriented programming. We cover the breadth and depth of Spring MVC, the WebSocket technology, Spring Data, and Spring Security with various authentication and authorization mechanisms. Packed with real-world examples, you’ll get an insight into utilizing the power of Spring Expression Language in your applications for higher maintainability. You’ll also develop full-duplex real-time communication channels using WebSocket and integrate Spring with web technologies such as JSF, Struts 2, and Tapestry. At the tail end, you will build a modern SPA using EmberJS at the front end and a Spring MVC-based API at the back end.By the end of the book, you will be able to develop your own dull-fledged applications with Spring.

Persisting data with Ember Data


Ember Data is Ember's data-access mechanism. It provides a simple API to deal with data, abstracting the complexities and protocols of data access and diverse data sources. With Ember Data, clients can deal with data models just as any other Ember object.

Ember Data defines a set of fundamental components that handle various roles and responsibilities in data access. These components are grouped under the namespace DS. The following table describes the most important Ember Data components defined under DS:

DS.Model

This is the fundamental unit of data and represents a record in a data collection. You need to define your data models by extending this class. It provides methods to save, delete, reload, and iterate properties, relationships, related types, and so on. It provides information about states, attributes, fields, relationships, errors, and so on. Also, it provides life cycle hook events.
