Either you experienced database connection issue or you missed any of the hibernate configurations to connect to database such as database DIALECT.

Happens if your database server was disconnected due to network related issue.

If you’re using spring boot along with hibernate connected to Oracle Db, use

hibernate.dialect=org.hibernate.dialect.HSQLDialect
hibernate.show_sql=true
hibernate.hbm2ddl.auto=update
hibernate.generate_statistics=true
entitymanager.packagesToScan: com

Solution 3

You don’t need hibernate-entitymanager-xxx.jar, because of you use a Hibernate session approach (not JPA). You need to close the SessionFactory too and rollback a transaction on errors. But, the problem, of course, is not with those.

This is returned by a database

#
org.postgresql.util.PSQLException: FATAL: password authentication failed for user "sa"
#

Looks like you’ve provided an incorrect username or (and) password.
