spring.jpa.hibernate.ddl-auto=none
spring.datasource.initialization-mode=always
spring.jpa.properties.hibernate.globally_quoted_identifiers=true

Answer 1

If you are looking for to create database if not exists then you can use below in database configuration file.

jdbc:mysql://localhost:3306/dbname?createDatabaseIfNotExist=true

Otherwise make sure you have below properties in your application properties file.

spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.hibernate.ddl-auto=update
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/dbname
spring.datasource.username=username
spring.datasource.password=password

Answer 2

You should be setting the property with a value that actually creates the schema, for instance:

spring.jpa.hibernate.ddl-auto=create-drop

I have added the following option:

"createDatabaseIfNotExist=true"
spring.datasource.url=jdbc:mysql://localhost:3306/"DB_NAME"?createDatabaseIfNotExist=true
