Erorr using MySQL and Spring boot app with docker

I try to connet my spring boot app with MySQL Docker Container. I ran :

docker run --name mysql-demo -e MYSQL_ROOT_PASSWORD=password -e MYSQL_DATABASE=test -e MYSQL_USER=sa -e MYSQL_PASSWORD=password -d mysql:lat

and got

CONTAINER ID   IMAGE          COMMAND                  CREATED          STATUS          PORTS                 NAMES
8d540d1824b9   mysql:latest   "docker-entrypoint.s…"   23 minutes ago   Up 23 minutes   3306/tcp, 33060/tcp   mysql-demo

In my spring app I have a property file:

spring.datasource.url=jdbc:mysql://mysql-demo:3306/test
spring.datasource.username=sa
spring.datasource.password=password
spring.jpa.hibernate.ddl-auto=update
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect

when I try to run this app or build a jar it crash with this error

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

The app working if I use mysql locally without docker

You didn't expose the port 3306. You must do that by using -p3306:3306 otherwise you cannot access this port.

docker run -p3306:3306 --name mysql-demo -e MYSQL_ROOT_PASSWORD=password -e MYSQL_DATABASE=test -e MYSQL_USER=sa -e MYSQL_PASSWORD=password -d mysql:lat
