Spring Boot MVC application with Postgresql deployment failed in Heroku - postgresql

Question

I have a Spring Boot MVC project. It works fine with h2 database and also fine in local postgre database with following application.properties configuration
spring.datasource.url=myUrl
spring.datasource.username=myUsername
spring.datasource.password=myPassword
But when I am trying to deploy it in Heroku it is getting this following error:
Caused by: org.hibernate.HibernateException: Access to
DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
If I use this configuration
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.datasource.driverClassName=org.postgresql.Driver
spring.datasource.url=herokuPostgreSqlDbUrl
spring.datasource.username=herokuUsername
spring.datasource.password=mherokuPassword
I am getting this when try to run my project from STS and failed deployment.
Caused by: java.sql.SQLException: Driver:org.postgresql.Driver#17a3dff6
returned null for URL:myUrl
My pom is :
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.4-1206-jdbc42</version>
</dependency>
Can any body help ?

You need a proper JDBC url. See: https://springframework.guru/configuring-spring-boot-for-postgresql/
