Replace hsqldb with MySQL - mysql

Question

I have a Spring REST project configured with hsqldb.
I would like to change it to MySQL.
I have MySQL server installed and running, but I don't know how to modify this pom:
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<scope>runtime</scope>
</dependency>
PS.: Project im talking about comes as a source code for 'Spring REST' book:

Answer 1

As far I see you are using Spring Boot on this, so you can easy change the databases changing the drivers dependencies from:
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<scope>runtime</scope>
</dependency>
To
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
The driver version will be version on parent pom.
Then specify the parameters on properties
spring.datasource.url=jdbc:mysql://localhost:port/yourdb
spring.datasource.username=dbuser
spring.datasource.password=dbpass
spring.datasource.driver-class-name=com.mysql.jdbc.Driver # we can ommit this if we want, Spring Boot will deduce based on the classpath
For more configuration on databases you can see the properties available on appendix here
