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.

Unit testing with Mockito and Maven Surefire

Unit Tests are useful to keep an eye on the components' implementation. The legacy philosophy of Spring promotes reusable components application-wide. The core implementations of these components may either alter states (states of transitory objects) or trigger interactions with other components.

Using Mocks in Unit Tests specifically assesses the behavior of component's methods in regard to other components. When the developer gets used to Mocks, it is amazing to see how much the design becomes influenced toward the use of different layers and logic externalization. Similarly, object names and method names are given more importance. Because they summarize something that is happening elsewhere, Mocks save the energy of the next developer that will have to operate in the area of code.

Developing Unit Tests is by definition an Enterprise policy. As the percentage of code covered by tests can easily reflect the maturity of a product, this code-coverage...
