以下是代码的中文翻译：
Entity
@Entity
@Table(name = "tbl_book")
@Data
@Getter
@Setter
@ToString
public class Book {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private long id;
@Column(name="sku")
private String sku;
@Column(name="name")
private String name;
@Column(name="description")
private String description;
@Column(name="unit_price")
private BigDecimal unitPrice;
@Column(name="image_url")
private String imageUrl;
@Column(name="active")
private boolean active;
@Column(name="units_in_stock")
private int unitsInStock;
@Column(name="date_created")
private Date createdOn;
@Column(name="last_updated")
private Date updatedOn;
@ManyToOne
@JoinColumn(name="category_id",nullable=false)
private BookCategory category;
}
Controller
@RestController
@RequestMapping(path="/api/v1")
public class BookController {
@Autowired
public BookService bookService;
@GetMapping("/books")
public ResponseEntity<List<Book>> getAllBooks() {
return new ResponseEntity<>(bookService.getAllBooks(), HttpStatus.OK);
}
}
Service
@Service
public class BookService {
@Autowired
public BookRepository bookRepository;
public List<Book> getAllBooks(){
List<Book> books = bookRepository.findAll();
System.out.println("books:" + books);
return books;
}
}
日志（LOG）部分未提供具体翻译内容，仅包含数据库查询日志和一些输出信息。
请注意，你可以将上述代码粘贴到Java开发环境中以运行它，但由于代码中的特殊字符已经被转义，你可能需要手动恢复这些特殊字符以便代码正常工作。如果有任何其他问题或需要进一步的帮助，请告诉我。
