Spring 5.0 Projects

Overview of this book

Spring makes it easy to create RESTful applications, merge with social services, communicate with modern databases, secure your system, and make your code modular and easy to test. With the arrival of Spring Boot, developers can really focus on the code and deliver great value, with minimal contour. This book will show you how to build various projects in Spring 5.0, using its features and third party tools. We'll start by creating a web application using Spring MVC, Spring Data, the World Bank API for some statistics on different countries, and MySQL database. Moving ahead, you'll build a RESTful web services application using Spring WebFlux framework. You'll be then taken through creating a Spring Boot-based simple blog management system, which uses Elasticsearch as the data store. Then, you'll use Spring Security with the LDAP libraries for authenticating users and create a central authentication and authorization server using OAuth 2 protocol. Further, you'll understand how to create Spring Boot-based monolithic application using JHipster. Toward the end, we'll create an online book store with microservice architecture using Spring Cloud and Net?ix OSS components, and a task management system using Spring and Kotlin. By the end of the book, you'll be able to create coherent and ?exible real-time web applications using Spring Framework.

Creating an empty application


We will use Maven to generate an empty application with the structure required for Java-based web applications. If you do not have Maven installed, please follow the instructions here (https://maven.apache.org/install.html) to install Maven. Once installed, run the following command to create an empty application:

mvn archetype:generate -DgroupId=com.nilangpatel.worldgdp -DartifactId=worldgdp -Dversion=0.0.1-SNAPSHOT -DarchetypeArtifactId=maven-archetype-webapp

Running the preceding command will show the command-line argument values for confirmation as shown in the following screenshot: 

You would have to type in Y in the Command Prompt shown in the previous screenshot to complete the empty project creation. Now you can import this project into an IDE of your choice and continue with the development activity. For the sake of simplicity, we will use Eclipse, as it is among the most popular IDEs used by the Java community today. 

On successful creation of the application, you will see the folder structure, as shown in the following screenshot:

Note

You will see index.jsp added by default while creating the default project structure. You must delete it as, in this application, we will use Thymeleaf—another template engine to develop the landing page.
