Maven Hibernate Java Persistence API (JPA) with CRUD Operations using EntityManager [हिंदी Tutorial]

The provided code includes Java classes and an XML configuration file that demonstrate basic usage of JPA (Java Persistence API) for managing data in a database.

Notion Notes - https://cherry-celery-c43.notion.site...

The "UiMain" class contains the main method where JPA entities are used to perform CRUD (Create, Read, Update, Delete) operations on a "Products" table in a MySQL database.

The "Products" class is a JPA entity that maps to the "Products" table in the database. It has fields for the product ID, product name, quantity, and price. The class also includes constructors, getters, setters, and a toString method.

The "persistence.xml" file provides configuration details for JPA, including the database driver, URL, and login credentials. It specifies the persistence unit name as "products" to be used in the JPA code.

The code demonstrates how to create an EntityManagerFactory and EntityManager using the persistence unit name. It also shows how to perform JPA operations such as find, persist, remove, and merge on the "Products" table using JPA entities and transactions.

Overall, the code provides a basic understanding of how to use JPA for database operations in a Java application.
