Spring boot fails to load DataSource using PostgreSQL driver
spring.datasource.driver-class-name=org.postgresql.Driver
Make sure to reload your project if you recently just added postgres to your dependencies.
some time try re-import your mvn project if dependencies are not refreshed , also add following to your pom.xml
<dependency>
<groupId>postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.1-901.jdbc4</version>
</dependency>
Or to your build.gradle
implementation "postgresql:postgresql:9.1-901.jdbc4"
Where did this come from: database.driverClassName=org.postgresql.Driver
? Don't you mean spring.datasource.driverClassName
?
