![]() ![]() Cucumber: an automated acceptance testing framework that allows us to create text-based acceptance criteria and exercise our web service to ensure that all top-level functionality is correct during the development of the service.JUnit: an automated unit testing framework that will be used for unit and integration tests, as well as to automate the execution of our acceptance tests.Apache Maven: a build and dependency management tool that is used to build, execute tests, and package our web service into a Java Archive (JAR) file that will be executed to run our RESTful web service. ![]() Spring Boot: a convention-over-configuration framework that removes a majority of the boilerplate Spring code and configuration this framework allows us to develop and launch of web service with a fraction of the hassle of a standard Spring web service.Spring Model-View-Controller (MVC): the core framework of our web service this framework provides the necessary annotations and structure required to create our REST endpoints and serve these endpoints over HTTP.Apart from the process used to create the service, there are also numerous tools used to build, test, and deploy the system, including: For example, persistence logic and domain logic are not intertwined. This not only resulted in a simple set of classes, but a more easily distinguishable set of components. Our order management system was created using Test Driven Development (TDD), where tests were created first and each design decision and implemented component was focused on passing the created test cases. For more information on RESTful web services, see DZone's Foundations of RESTful Architecture Refcard and RESTful Web Services by Leonard Richardson and Sam Ruby. While we will deep dive into the design and implementation intricacies of creating a REST web service in Spring, we will not focus on the conceptual aspects of REST (such as the use of an HTTP GET or POST call). This article also assumes that the reader has a foundational understanding of REST and RESTful web services. For more information on DI in Spring, see the Spring Framework Guide and DZone's Spring Configuration Refcard. ![]() Although we will explore the DI framework configurations used and the DI components utilized in our order management system, it is assumed that the reader has at least a conceptual understanding of the need for and premise of DI. It is expected that the reader has at least a novice understanding of dependency injection (DI), particularly DI using the Spring framework. For the remainder of this article, when we refer to our order management system, we are actually referring to the Spring REST service contained in the above repository. Therefore, as we walk through each step in creating our REST service, the source code in the above repository should be visited consistently and used as the authoritative reference for all design and implementation choices. Instead, they serve as a snapshot or reflection of the source code contained in the above repository. The source code snippets in this article are not in-and-of-themselves sufficient for creating a fully functioning REST web service. All of the source code, including these supporting aspects, can be found in the following GitHub repository: While the source code illustrated in this article covers the essential aspects of the order management system, there are other components and code (such as test cases) that support the main service that are not shown. Although this management system will be simple compared to the large-scale RESTful services found today, it will nonetheless demonstrate the basic thought process, design decisions, and implementation tests required to create a Level 3 (hypermedia-driven) Spring REST web service.īy the end of this article, we will have created a fully functional Spring REST order management system. While both have their strengths and weaknesses, this article will focus on Spring and create a simple order management RESTful web application using Spring 4. ![]() Within the Java REST ecosystem, there are two popular contenders: Java Enterprise Edition (JavaEE) and Spring. Foremost among these web applications is the Representational State Transfer (REST) web service, with Java becoming one of the most popular implementation languages. In the modern world of interconnected software, web applications have become an indispensable asset. Create the main method that will run the application ![]()
