如何通过Spring Boot中entity中输入的关键字搜索产品？

@Entity
public class Product {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    private String name;
    
    private String description;
    
    // 其他属性和方法
}

@Repository
public interface ProductRepository extends JpaRepository<Product, Long> {
    List<Product> findByNameContaining(String keyword);
}

@Service
public class ProductService {
    @Autowired
    private ProductRepository productRepository;
    
    public List<Product> searchProducts(String keyword) {
        return productRepository.findByNameContaining(keyword);
    }
}

@RestController
@RequestMapping("/products")
public class ProductController {
    @Autowired
    private ProductService productService;
    
    @GetMapping("/search")
    public List<Product> searchProducts(@RequestParam("keyword") String keyword) {
        return productService.searchProducts(keyword);
    }
}
