While I was using Spring Boot 1.5, on application startup Hibernate executed schema.sql file located in /resources folder when appropriate configuration is set. After Spring Boot 2.0 release this feature does not work any more. I couldn't find anything about this change in documentation. Here is my application.properties file content:
spring.datasource.url=...
spring.datasource.username=...
spring.datasource.password=...
spring.jpa.hibernate.ddl-auto=none
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
Is there some change in Spring Boot 2.0 or is this an bug/issue?
Check the documents here.
In a JPA-based app, you can choose to let Hibernate create the schema or use schema.sql, but you cannot do both. Make sure to disable spring.jpa.hibernate.ddl-auto if you use schema.sql.
You have spring.jpa.hibernate.ddl-auto=create-drop that's why schema.sql is not executed.
Looks like this is the way Spring Boot works.
Edit
I think that the problem(not really a problem) is that your application points to a mysql instance.
See the current Spring Boot properties:
spring.datasource.initialization-mode=embedded # Initialize the datasource with available DDL and DML scripts.
The default value is embedded - e.g. initialize only if you're running and embedded database, like H2.
Also see the answer of Stephan here. He said:
Adding spring.datasource.initialization-mode=always to your project is enough.
So try to set:
spring.datasource.initialization-mode=always
