As Java developers, we’ve been to a point where we feel Java codes are too verbose no matter how we refactor existing codes. At times, doing something simple requires too many codes.

With Java 8, things became a bit better with Streams, Lambdas and etc. Still Java is too verbose. Good thing there are alternatives with Java. These include Groovy and Kotlin.

These languages are concise, safer, 100% interoperable with Java and tool-friendly.

Spring Boot Project

The following are the steps on how to create a Kotlin-based Spring Boot Project.

New Project

To create a new project, go to File -> New -> Project... This will open the New Project window. Choose Spring Initialzr from the left panel and click Next.

Next, provide some details about the project. Choose Kotlin as the language.

Next, just click Next. We select nothing.

Next, provide additional details. Click Finish when done.

Once done, we’ll have this:

Test Out

We’ll try out by creating a class annotated with @Component and using that in the main function.

Bean class

Modified main function

In these codes, we retrieved an object of type MyMessageBean from the Spring Container and display its content.

Sample Output
