Demo: Loading Resources in Micronaut using Readable

In this demo I show have you can use Micronaut's Readable interface to load resources from either the classpath, or the filesystem in an implementation agnostic fashion.

How to Run

git clone https://github.com/ghillert/resource-readable-demo.git
./cd resource-readable-demo

./mvnw mn:run

./mvnw clean package
java -jar target/resource-readable-demo-0.1.jar --images.image-file=file:/Users/hillert/Desktop/end-of-springone-2020.jpg

The following 2 REST API endpoints are available:

• http://localhost:8080/images/single
• http://localhost:8080/images/random

If you like to override the property for the single image images.image-file and load an image from the file-system instead, you can do that e.g. with:

java -jar target/resource-readable-demo-0.1.jar --images.image-file=file:/my/path/to/some/awesome-image.jpg

or

./mvnw mn:run -Dmn.appArgs="--images.image-file=file:/my/path/to/some/awesome-image.jpg"
