Overview of this book

Spring MVC is a lightweight application framework that comes with a great configuration by default. Being part of the Spring Framework, it naturally extended and supported it with an amazing set of recognizable annotations. External libraries can be plugged in and plugged out. It also possesses a request flow. Complete support of REST web services makes the Spring architecture an extremely consistent choice to support your front-end needs and Internet transformations. From the design of your Maven modules, you will achieve an Enterprise-standard for a stateless REST application based on Spring and Spring MVC with this book. This guide is unique in its style as it features a massive overview of practical development techniques brought together from the Spring ecosystem, the new JEE standards, the JavaScript revolution and Internet of Things. You will begin with the very first steps of Spring MVC's product design. Focused on deployment, viability, and maintainability, you will learn the use of Eclipse, Maven, and Git. You will walk through the separation of concerns driven by the microservices principles. Using Bootstrap and AngularJS, you will develop a responsive front-end, capable of interacting autonomously with a REST API. Later in the book, you will setup the Java Persistence API (JPA) within Spring; learn how to configure your Entities to reflect your domain needs, and discover Spring Data repositories. You will analyze how Spring MVC responds to complex HTTP requests. You will implement Hypermedia and HATEOAS to guide your customer's stateless conversation with the product and see how a messaging-service based on WebSocket can be configured. Finally you will learn how to set up and organize different levels of automated-tests, including logging and monitoring.

Streaming social events with STOMP over SockJS

In this recipe, we broadcast user activities (events) with STOMP over SockJS. SockJS provides a custom implementation of WebSocket.

Getting ready

There is some configuration work to be done beforehand, especially on the Apache HTTP proxy. After that, we will see how to initiate a WebSocket with SockJS and with AngularJS on the client side.

Our WebSocket will subscribe to a topic (for broadcasting) published via Spring from the cloudstreetmarket-api module.

How to do it…

From the Git Perspective in Eclipse, checkout the latest version of the branch v8.1.x.
Run the Maven clean and Maven install commands on the zipcloud-parent project (right-click on the project, select Run as… | Maven Clean, then select Run as… | Maven Install). After this, operate a Maven | Update Project to synchronize Eclipse with the Maven configuration (right-click on the project and then click Maven | Update Project…).
Similarly, run the Maven clean and Maven install commands...
