How do I map entities in Spring Boot using JPA?

To map entities in Spring Boot using JPA, you typically use annotations like @Entity, @Table, and @Id.

Can you give me an example of a simple entity class?

Sure! Here's a basic example:

@Entity
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String name;
    private String email;

    // Getters and Setters
}

What about relationships between entities?

You can use annotations like @OneToMany, @ManyToOne, and @ManyToMany to define relationships between entities.

How do I handle cascading operations?

You can use the cascade attribute in your relationship annotations, like this: @OneToMany(cascade = CascadeType.ALL).
