I had this add this in application.properties:
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect
to solve the previous problem
and then I got another problem: The server time zone value 'PDT' is unrecognized, and I found some stackoverflow post, I didn't keep track of it but the workaround solution is add some parameters in the data source url:
spring.datasource.url=jdbc:mysql://localhost:3306/db_example?useLegacyDatetimeCode=false&serverTimezone=UTC

commented

@wssrcok,
You need to add pre-defined database connection attributes into the application.properties file.
Then re-run your Spring Boot application.

spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://${MYSQL_HOST:localhost}:3306/db_example
spring.datasource.username=springuser
spring.datasource.password=ThePassword
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
#spring.jpa.show-sql: true
