Spring 5, Hibernate 5, Postgresql - error "Cannot unwrap to requested type [javax.sql.DataSource]"

I am learing Spring 5. I have converted Spring 5 MVC + Hibernate 5 Example tutorial from HSQL to PostgreSQL one, but it has not worked. The error is:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'getTransactionManager' defined in com.howtodoinjava.demo.spring.config.HibernateConfig: Invocation of init method failed; nested exception is org.hibernate.service.UnknownUnwrapTypeException: Cannot unwrap to requested type [javax.sql.DataSource]
How to fix it?
Here you are files of the project and bigger error message:

The reason was an IntelliJ issue that rebuilding artifacts was needed.
After that it worked. So the error message was not relating to the code in my question.

Any help would be appreciated.

Yup, as #Kayaman pointed out in comments, adding spring core dependency should solves it.
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>5.0.2.RELEASE</version>
</dependency>

The problem was for my other dependencies version
I changed them and problem solved

Spring Boot App Doesn't Work on AWS - Tomcat Throws UnsatisfiedDependencyExceptions

I have a restful server i want to deploy on an AWS virtual machine. The application works fine on my local tomcat. I am able to access to the tomcat's default pages & manager apps from my browser and it works fine as well. But when i deploy the war file on tomcat it deploys but says
FAIL - Application at context path /zift-0.0.1-SNAPSHOT could not be started
I checked on catalina.out and realized i get mostly "UnsatisfiedDependencyExceptions", weird that i get none of them in my own computer. Here is the catalina.out:

When you said that you're not having problems on your computer is because you're running your project on the embedded tomcat in the STS? Because if that's the case you are have to add WebApplicationInitializer.

So, what am I doing wrong?

You didn't defined any strategy to your generated id for message.
By default, Hibernate will check on your database to find any sequence or strategy to generate values. Try this :
#GeneratedValue(strategy = GenerationType.IDENTITY)

I tried replacing the following code in adduser.java file
Configuration config = new Configuration().configure();
ServiceRegistry servReg = new StandardServiceRegistryBuilder().applySettings(config.getProperties()).build();
SessionFactory factory = config.buildSessionFactory(servReg);
with
SessionFactory factory = new Configuration().configure()
.buildSessionFactory();
Rest all same.It's working for me.

Since you are using annotations you should change this line:
Configuration config = new Configuration().configure();
to
Configuration config = new AnnotationConfiguration().configure();
A very basic example almost identical to yours can be found at: http://www.concretepage.com/hibernate/example_annotationconfiguration_hibernate
