Autoconfig for flapdoodle embedded MongoDB support was removed after Spring Boot 2.7.0.
https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.0-Migration-Guide#embedded-mongodb

You can use this library instead of the dependency shown in the book to get the code to run:

<dependency>
	<groupId>de.flapdoodle.embed</groupId>
	<artifactId>de.flapdoodle.embed.mongo.spring3x</artifactId>
	<version>4.18.0</version>
</dependency>

You also need to add this to application.properties to get it to know which version of mongo to use:

de.flapdoodle.mongodb.embedded.version=4.0.2

This works for my project in Java 17, Spring Boot 3.4.1
