EntityManagerFactory простаивает перед закрытием

После запуска программы и выполнения каких-либо действий EntityManagerFactory простаивает ровно одну минуту перед тем, как закрыться и завершить программу. Как сделать так, чтобы он закрывался сразу же после использования?

Application.properties:

spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
spring.jpa.generate-ddl=true
