Before trying to launch the app make sure your have JDK 11 installed and environment variables set up.
Download the xml-reader-app.jar file and move it to any place that suits for you. For example: C:\xml-reader-app.jar
Optional In the same folder create a file application.properties and put links to the books you want to parse, for example:
For multiple links use comma without spaces.
Then in terminal go to the folder and run the app with java -jar xml-reader-app.jar command.
To see the parsed json, go to http://localhost:8080/books
