How do I configure data source using Spring boot?

Include starter dependencies spring-boot-starter-jdbc or spring-boot-starterdata-jpa and include a JDBC driver on classpath. Spring boot will configure the database with the properties defined in application.properties.

spring.datasource.url=jdbc:mysql://localhost:2001/mydb
spring.datasource.username=username
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

Spring boot can even auto-configure connection pool given the jar provided in the classpath and properties set.
