Developing Java Applications with Spring and Spring Boot

Overview of this book

Spring Framework has become the most popular framework for Java development. It not only simplifies software development but also improves developer productivity. This book covers effective ways to develop robust applications in Java using Spring. The course is up made of three modules, each one having a take-away relating to building end-to-end java applications. The first module takes the approach of learning Spring frameworks by building applications.You will learn to build APIs and integrate them with popular fraemworks suh as AngularJS, Spring WebFlux, and Spring Data. You will also learn to build microservices using Spring's support for Kotlin. You will learn about the Reactive paradigm in the Spring architecture using Project Reactor. In the second module, after getting hands-on with Spring, you will learn about the most popular tool in the Spring ecosystem-Spring Boot. You will learn to build applications with Spring Boot, bundle them, and deploy them on the cloud. After learning to build applications with Spring Boot, you will be able to use various tests that are an important part of application development. We also cover the important developer tools such as AMQP messaging, websockets, security, and more. This will give you a good functional understanding of scalable development in the Spring ecosystem with Spring Boot. In the third and final module, you will tackle the most important challenges in Java application development with Spring Boot using practical recipes. Including recipes for testing, deployment, monitoring, and securing your applications. This module will also address the functional and technical requirements for building enterprise applications. By the end of the course you will be comfortable with using Spring and Spring Boot to develop Java applications and will have mastered the intricacies of production-grade applications.

Creating the REST resources

Now, we have an application up and running in this section, and we will add some REST endpoints and model some initial classes for the CMS application, the REST endpoints will be useful for the AngularJS integration.

One of the required characteristics for the APIs is the documentation, and a popular tool to help us with these tasks is Swagger. The Spring Framework supports Swagger, and we can do it with a couple of annotations. The project's Spring Fox is the correct tool to do this, and we will take a look at the tool in this chapter.

Let's do this.


Before we start to create our class, we will add the Lombok dependency in our project. It is a fantastic library which provides some interesting things such as GET/SET at compilation time, the Val keyword to make variables final, @Data to make a class with some default methods like getters/setters, equals, and hashCode.

Adding Lombok dependency

Put the following dependency in a pom.xml file:
