Auto creation of Spring batch schema with boot - spring

Question

I am trying to write my first spring batch example with spring boot . I want to create database in mysql as soon as application starts up.
I have following dependencies in my pom
<?xml version="1.0" encoding="UTF-8"?>

</build>
</project>
and application.properties has following configuration
spring.datasource.url=jdbc:mysql://localhost:3306/batchjob?allowPublicKeyRetrieval=true&useSSL=false
spring.datasource.username=root
spring.datasource.password= abcd1234
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.schema=schema-mysql.sql
spring.batch.initialize-schema=always
But when I'm starting application, it is not able to recognize Mysql and in the logs it is printing following line
2019-03-10 14:32:01.381 INFO 48560 --- [ main] o.s.b.c.r.s.JobRepositoryFactoryBean : No database type set, using meta data indicating: HSQL
What am I missing which will enable auto schema creation in mySql ?

Answer 1

You shoud add this:
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect

Answer 2

DDL scripts are in the org.springframework.batch.core package, so your spring.datasource.schema should be:
spring.datasource.schema=org/springframework/batch/core/schema-mysql.sql
You can even omit this property as it will be detected automatically from your datasource.
