Developing Java Applications with Spring and Spring Boot

How to do it...

1. Create a new package folder named entity under the src/main/java/com/example/bookpub directory from the root of our project.
2. In this newly created package, create a new class named Book with the following content:

@Entity 
public class Book { 
  @Id 
  @GeneratedValue 
  private Long id; 
  private String isbn; 
  private String title; 
  private String description; 
 
  @ManyToOne 
  private Author author; 
  @ManyToOne 
  private Publisher publisher; 
 
  @ManyToMany 
  private List<Reviewers> reviewers; 
 
  protected Book() {} 
 
  public Book(String isbn, String title, Author author,        Publisher publisher) { 
    this.isbn = isbn; 
    this.title = title; 
    this.author = author; 
    this.publisher = publisher; 
  } 
  //Skipping getters and setters to save space, but we do need them 
}
