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.

Handling routes


An Ember application transitions its state between a set of routes; each can render a template that displays the current state and a controller to support its state-based data. Routes are registered inside the router configuration, typically inside router.js, in the case of an Ember CLI project structure. Routes are defined inside their own JS files.

Routes can be generated and autoconfigured from the command line as follows:

ember generate route user --pod

This command generates route.js and template.hbs under app/<pod-directory>/user/. Upon generation, both artifacts will have a basic structure and you need to flesh them out according to your specific requirements. A typical route will have a model hook, which prepares its data. See the structure of a typical but minimal route given in the following code:

import Ember from 'ember';

export default Ember.Route.extend({

  model: function(args) {
    return this.store.findAll('task');
  }
});

In the preceding example,...
