Using MySQL with Spring boot docker image
I have this problem that I can't really find a solution. It can be a silly question for most of you but I hope someone offers a little help to this newbie :)
I have 1GB droplet and I installed mysql using this page. I logged in mysql console, imported my database, created a new user with required permissions. Its all good until this point.
I have pulled my docker image from docker hub with this line:
docker run --rm -p 80:80 my-username/image-name
It downloaded for the first time and started my Spring boot application but I got this exception every time I try to run my image.
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. .... Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
my application.yaml file looks like this:
spring: mvc: view: prefix: /WEB-INF/jsp/ suffix: .jsp datasource: url: jdbc:mysql://localhost:3306/db-name username: my-username password: secret-pwd driver-class-name: com.mysql.jdbc.Driver jpa: hibernate: dialect: org.hibernate.dialect.MySQLInnoDBDialect generate-ddl: true
MySQL server is up and running. What am I missing here?
