Answer 1

As the Spring boot documentation mentioned, what have fixed my issue was adding spring.datasource.platform to the application.properties. That is what I have been missing to initialize the schema using schema-{platform}.sql and data-{platform}.sql.

{platform} = value of spring.datasource.platform

So my final application.properties file is,

spring.datasource.url = jdbc:mysql://localhost:3306/testdb?useSSL=false
spring.datasource.username = root
spring.datasource.password = password

spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1

spring.datasource.driverClassName = com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto = validate
spring.jpa.show-sql = true
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

spring.datasource.platform=mysql
spring.datasource.schema=schema-mysql.sql
spring.datasource.data=data-mysql.sql
spring.datasource.initialize=true
spring.datasource.continue-on-error=true
