APPLICATION FAILED TO START

Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
application.properties 에 다음과 같이 JDBC url을 추가해준다. [Mysql 일 경우] (Oracle이나 다른 DB는 응용하세요.)
# DataSource
spring.datasource.url=jdbc:mysql://localhost:3306/happyhouse?autoReconnect=true
spring.datasource.username=root
spring.datasource.password=1234
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
