@RestController @RequestMapping("/api/books") public class BookController { @Autowired private BookRepository bookRepository; @GetMapping public List<Book> getAllBooks() { return bookRepository.findAll(); } @GetMapping("/{id}") public Book getBookById(@PathVariable Long id) { return bookRepository.findById(id).orElseThrow(); } @PostMapping public Book createBook(@RequestBody Book book) { return bookRepository.save(book); } @PutMapping("/{id}") public Book updateBook(@PathVariable Long id, @RequestBody Book book) { Book existingBook = bookRepository.findById(id).orElseThrow(); existingBook.setTitle(book.getTitle()); existingBook.setAuthor(book.getAuthor()); return bookRepository.save(existingBook); } @DeleteMapping("/{id}") public void deleteBook(@PathVariable Long id) { bookRepository.deleteById(id); } } This code defines a simple RESTful API that provides access to a database of books. With Spring Boot, we can create a fully-functional API like this in just a few minutes.
