docker compose: spring boot connection to mysql database refused
问题 I'm pretty new to Docker and I need to startup my Angular/SpringBoot/MySQL project with docker-compose on the docker toolbox. I copied a docker yml file into my project which used the same technologies and changed the paths inside of it to match my project. However when I try docker-compose, it throws the following error: com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure [...] 84 common frames omitted Caused by: java.net.ConnectException: Connection refused
