How to use Lambok dependency in SpringBoot?

Question

I have just added Lombok dependency to my SpringBoot project so I don't have to repeat lines of getters, setters and constructors...

Here is my code example:

Book.java

@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
@ToString
@Entity
@Table(name = "Books")
public class Book {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;

    private String title;
    private String ISBN;
    private String author;
    private String issuer;
    private Integer dateOfIssue;
    private Boolean IsRented;

}

But now in my BookService.java I have all the getters and setters turned red with error saying

Cannot resolve method 'setTitle' in 'Book'

This is how I am trying to use getters and setters:

public Book updateBook(Book book){
        Book existingBook = bookRepo.findById(book.getId()).orElse(null);

        existingBook.setTitle(book.getTitle());
        existingBook.setISBN(book.getISBN());
        existingBook.setAuthor(book.getAuthor());
        existingBook.setIssuer(book.getIssuer());
        existingBook.setDateOfIssue(book.getDateOfIssue());
        existingBook.setDateOfIssue(book.getDateOfIssue());
        existingBook.setRented(book.getRented());

        return bookRepo.save(existingBook);
    }

Why is that happening? When I had my getters and setters written like:

 public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

everything was okay but as I removed that and added Lombok it seems like I can't reach to my getters and setters.

It seems you are using an IDE. For your IDE to recognize the code autogenerated by Lombok you need to install it on your IDE as well as having it as a dependency of your project. The web site for Lombok has instructions on how to do this. For example, if you are using Eclipse, the instructions are here.

And if using intellij: https://projectlombok.org/setup/intellij – pedrohreis Aug 27 '20 at 14:02
Hi mate thank you that was it! I am working on Mac and I had to go to `Intelij IDE > Preferences > Build, Execution, Deployment > Annotation Processors and Enable annotation processing`. `Then also to Preferences > plugins > Lombok Plugin > Install` and it works just fine. – user9347049 Aug 27 '20 at 14:12
