I’m trying to connect the bank with Springboot and I’m thinking my problem is here:

# ===============================
# = DATA SOURCE
# ===============================
# Set here configurations for the database connection
spring.datasource.url=jdbc:postgresql://localhost:5432/springbootdb?createDatabaseIfNotExist=true&useSSL=false
spring.datasource.username=postgres
spring.datasource.password=1234
spring.datasource.driver-class-name=org.postgresql.Driver

# ===============================
# = JPA / HIBERNATE
# ===============================
# Show or not log for each sql query
spring.jpa.show-sql=true
# Hibernate ddl auto (create, create-drop, update): with "create-drop" the database
# schema will be automatically created afresh for every start of application
spring.jpa.hibernate.ddl-auto=create-drop


# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect

This is my pom.xml

Even the drive is installed as you can see:

This mistake has nothing to do with Postgre.

Reading the error you can see the following message: "The Tomcat Connector configured to Listen on port 8080 failed to start. The port may already be in use or the Connector may be misconfigured."

What must be happening is that you are trying to run the application with the same in the air.

Stop Tomcat and make sure the application is out (just go to the link http://localhost:8080).

Note: To stop the Tomcat just click on a red square that is located in the upper right corner of the Console tab.

Done this go up the project again, if there is an error regarding the bank, comment here again.
