  2. In One to Many Bidirectional Mapping, we use JPA @OneToMany and @ManyToOne annotations for mapping with a database table1. A one-to-many association links two tables based on a Foreign Key column so that the child table record references the Primary Key of the parent table row1. This tutorial will walk you through the steps of using @OneToMany and @ManyToOne to do a bidirectional mapping for a JPA and Hibernate One to Many relationship, and writing CRUD REST APIs to expose the relationship for accessing the database in Spring Boot, Spring Data JPA, and MySQL2.

    What is one-to-many bidirectional entity mapping in JPA & hibernate?
    We can navigate this type of association from both sides. In this example, we implement step-by-step one-to-many bidirectional entity mapping using JPA and Hibernate, and the MySQL database. Simply put, one-to-many mapping means that one row in a table is mapped to multiple rows in another table.

    What is the difference between bidirectional and one-to-many bidirectional association mapping?
    Tables of both the persistence classes will be related in database. If one persistence object uses other and in back if other using the first persistence object then it becomes bidirectional. If it is bidirectional, then one-to-many bidirectional association mapping and many-to-one bidirectional association mapping both become one and same.
