Overview of this book

With Google's inclusion of first-class support for Kotlin in their Android ecosystem, Kotlin's future as a mainstream language is assured. Microservices help design scalable, easy-to-maintain web applications; Kotlin allows us to take advantage of modern idioms to simplify our development and create high-quality services. With 100% interoperability with the JVM, Kotlin makes working with existing Java code easier. Well-known Java systems such as Spring, Jackson, and Reactor have included Kotlin modules to exploit its language features. This book guides the reader in designing and implementing services, and producing production-ready, testable, lean code that's shorter and simpler than a traditional Java implementation. Reap the benefits of using the reactive paradigm and take advantage of non-blocking techniques to take your services to the next level in terms of industry standards. You will consume NoSQL databases reactively to allow you to create high-throughput microservices. Create cloud-native microservices that can run on a wide range of cloud providers, and monitor them. You will create Docker containers for your microservices and scale them. Finally, you will deploy your microservices in OpenShift Online.

Packaging and running a Spring Boot application


Now that we know something more about building microservices within Spring Boot, we need to package and run our service. This will teach us how to package a Spring Boot application.

Then, we will analyze the difference between packaging, using JARs or WARs.

Finally, we learn how to run the package applications, and how to creating self-executables JARs.

Packaging

We can package the application using the Maven lifecycle phase package, either using the IntelliJ Maven projects window or from the command line.

Note

We can open a command line to the project folder from IntelliJ using the terminal window from the menu—View | Tool Windows | Terminal or using the Alt + F12 keybinding.

mvnw package

Running this from our example project will create a file named chapter2-0.0.1-SNAPSHOT.jar under the target folder.

This command will create a JAR that contains all dependencies required by the application that we are packaging, in our case all the Spring components...
