JPA / Hibernate Composite Primary Key Example with Spring Boot

In this video, we will learn how to map a composite primary key in Hibernate using JPA’s @Embeddable and @EmbeddedId annotations. In a real-time situation, there can be scenarios when one column is not good enough to uniquely identify a row. In such scenarios, we use a combination of columns to uniquely identify a row. SQL composite key is a combination of two or more columns in a table that is used to uniquely identify a row. The combination of the columns guarantees uniqueness. We will create a Spring boot project to demonstrates composite key mapping using JPA/Hibernate. #javaguides #hibernate #springboot
