“Can you explain the steps for connecting to a database in Hibernate?”

  1. Add database driver dependency: Add the corresponding database driver dependency in the project’s pom.xml file, for example, the driver dependency for MySQL is mysql-connector-java.
  2. Set up the Hibernate configuration file: create a configuration file called hibernate.cfg.xml, and configure the database connection information and entity class mapping information.
  3. Create entity class: Develop a class that corresponds with a database table, and map the class to the database table using annotations or XML files.
  4. Create a Hibernate utility class: Develop a utility class to obtain the SessionFactory object, fetch the Session object via the SessionFactory, and perform database operations.
  5. Write data manipulation code: Within the specific business logic, utilize the Hibernate utility class to perform database operations such as inserting, deleting, updating, and querying using the Session object.
  6. Close resources: Remember to close Session and SessionFactory when the program ends to release database connections.
