Spring session jdbc fails to start - spring-boot

Question

I'm trying to configure a database stored session with spring session in a sprinboot application
I have already created tables spring_session and spring_session_attributes, however it fails to start:
These are my properties:
spring.session.jdbc.table-name:SPRING_SESSION
spring.datasource.driver-class-name:org.postgresql.Driver
spring.datasource.url:jdbc:postgresql://my_server:my_port/my_schema
spring.datasource.username:my_user
spring.datasource.password:my_password
This is the exception that I get:
11:47:56.276 [restartedMain] ERROR o.s.~.SpringApplication - Application startup failed

Answer 1

I needed to add jpa library
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
That was enough

Answer 2

spring.session.jdbc.table-name=SPRING_SESSION
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url.jdbc=postgresql://my_server:my_port/my_schema
spring.datasource.username=my_user
spring.datasource.password=my_password
this is example of using spring boot with mysql
https://spring.io/guides/gs/accessing-data-mysql/
and application.properties looks like
spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=jdbc:mysql://localhost:3306/db_example
spring.datasource.username=springuser
spring.datasource.password=ThePassword
