The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.
Hibernate ORM is an object-relational mapping framework for the Java language. It provides a framework for mapping an object-oriented domain model to a relational database.
If we use javax.persistence.CascadeType.All for deleting child records it will delete only collection of strings. Other than collection of strings in order to delete we need to useFor Example,
org.hibernate.annotations.CascadeType.DELETE_ORPHAN to delete the child records.
public class Employee {
@OneToMany(cascade = {CascadeType.ALL})
@Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
List<Department> departments;
}
