Hacking with Spring Boot
Using JDK 20+ and Maven 3.9.x, the Spring Boot starters to show off a few features for a series of articles.
This project will be added to over time as additional demos are created.
Demonstrations
Using Spring Shell
Running the ./run-with-spring-shell.sh script will launch the Spring Boot application and then begin a Spring Shell session. Commands are defined in the ...shellui package. The commands let the user interact with a Redis server.
Using JShell with Spring Boot
Running the ./jshell.sh script builds the project and then launches JShell, booting the Spring container and exposing it as context in the shell itself. Any Spring component can then be accessed via getBean on the context object and called.
