Spring commandfast Sample Application

April 6, 2022 · View on GitHub

This is a fork of https://github.com/spring-projects/spring-commandfast to be used for the PSG2 course. The main changes that have been performed were:

  • Trimming several parts of the application to keep the example low
  • Reorganize some parts of the code according to best practices introduced in the DP1 course

Running commandfast locally

commandfast is a Spring Boot application built using Maven. You can build a jar file and run it from the command line:

git clone https://github.com/gii-is-PSG2/spring-commandfast.git
cd spring-commandfast
./mvnw package
java -jar target/*.jar

You can then access commandfast here: http://localhost:8080/

Or you can run it from Maven directly using the Spring Boot Maven plugin. If you do this it will pick up changes that you make in the project immediately (changes to Java source files require a compile as well - most people use an IDE for this):

./mvnw spring-boot:run
