ORA-01017 database connection Error

ORA-01017

When connecting to the database, I don't know if the original server-side program didn't stop, so I encountered a few problems with database connection.

It was a bit strange. Later, I re-opened the project and compiled it again.

When there is a problem with the Association of new objects, it is still not enough to write the program into the hibernate configuration file to write a name wrong.
