使用Java编程和springboot框架实现对奖品表的管理功能 其中包括文件上传功能给出相应的controller层，service层，daoc层及mapper

好的，我可以为您提供一个简单的实现，但请注意这只是一个示例，并不一定适用于您的具体情况。

首先，在 pom.xml 文件中添加以下依赖项：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
        <optional>true</optional>
    </dependency>

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <optional>true</optional>
    </dependency>

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>runtime</scope>
    </dependency>

    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-io</artifactId>
        <version>1.3.2</version>
    </dependency>
</dependencies>

接下来，我们需要创建一个奖品类 Prize：

@Entity
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
public class Prize {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(nullable = false)
    private String name;

    @Column(nullable = false)
    private String description;

    private String imageUrl;
}

然后，我们需要创建一个 PrizeRepository 接口：

public interface PrizeRepository extends JpaRepository<Prize, Long> {
}

接下来，我们需要创建一个 PrizeService 类：

@Service
public class PrizeService {
    private final PrizeRepository prizeRepository;

    public PrizeService(PrizeRepository prizeRepository) {
        this.prizeRepository = prizeRepository;
    }

    public List<Prize> getAllPrizes() {
        return prizeRepository.findAll();
    }

    public Prize getPrizeById(Long id) {
        return prizeRepository.findById(id).orElse(null);
    }

    public void savePrize(Prize prize) {
        prizeRepository.save(prize);
    }

    public void deletePrize(Long id) {
        prizeRepository.deleteById(id);
    }
}

然后，我们需要创建一个 PrizeController 类：

@Controller
public class PrizeController {
    private final PrizeService prizeService;

    public PrizeController(PrizeService prizeService) {
        this.prizeService = prizeService;
    }

    @GetMapping("/")
    public String index(Model model) {
        model.addAttribute("prizes", prizeService.getAllPrizes());
        return "index";
    }

    @GetMapping("/prize/{id}")
    public String getPrize(@PathVariable Long id, Model model) {
        Prize prize = prizeService.getPrizeById(id);
        model.addAttribute("prize", prize);
        return "prize";
    }

    @GetMapping("/prize/new")
    public String newPrize(Model model) {
        model.addAttribute("prize", new Prize());
        return "new_prize";
    }

    @PostMapping("/prize/new")
    public String createPrize(@ModelAttribute Prize prize, @RequestParam("image") MultipartFile image) throws IOException {
        if (!image.isEmpty()) {
            byte[] bytes = image.getBytes();
            String fileName = image.getOriginalFilename();
            Path path = Paths.get("uploads/" + fileName);
            Files.write(path, bytes);
            prize.setImageUrl(fileName);
        }
        prizeService.savePrize(prize);
        return "redirect:/";
    }

    @GetMapping("/prize/edit/{id}")
    public String editPrize(@PathVariable Long id, Model model) {
        Prize prize = prizeService.getPrizeById(id);
        model.addAttribute("prize", prize);
        return "edit_prize";
    }

    @PostMapping("/prize/edit/{id}")
    public String updatePrize(@PathVariable Long id, @ModelAttribute Prize prize, @RequestParam("image") MultipartFile image) throws IOException {
        Prize existingPrize = prizeService.getPrizeById(id);
        if (existingPrize != null) {
            existingPrize.setName(prize.getName());
            existingPrize.setDescription(prize.getDescription());
            if (!image.isEmpty()) {
                byte[] bytes = image.getBytes();
                String fileName = image.getOriginalFilename();
                Path path = Paths.get("uploads/" + fileName);
                Files.write(path, bytes);
                existingPrize.setImageUrl(fileName);
            }
            prizeService.savePrize(existingPrize);
        }
        return "redirect:/";
    }

    @GetMapping("/prize/delete/{id}")
    public String deletePrize(@PathVariable Long id) {
        prizeService.deletePrize(id);
        return "redirect:/";
    }
}

最后，我们需要创建相应的 HTML 模板：

index.html：

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Prize List</title>

    <tr>
        <th>ID</th>
        <th>Name</th>
        <th>Description</th>
        <th>Image</th>
        <th>Actions</th>
    </tr>
    </thead>
    <tbody>
    <tr th:each="prize : ${prizes}">
        <td th:text="${prize.id}"></td>
        <td th:text="${prize.name}"></td>
        <td th:text="${prize.description}"></td>
        <td>
            <img th:src="@{uploads/} + ${prize.imageUrl}" width="100" height="100"/>
        </td>
        <td>
            <a th:href="@{/prize/{id}(id=${prize.id})}">View</a>
            <a th:href="@{/prize/edit/{id}(id=${prize.id})}">Edit</a>
            <a th:href="@{/prize/delete/{id}(id=${prize.id})}">Delete</a>
        </td>
    </tr>
    </tbody>
</table>
<a th:href="@{/prize/new}">Add New Prize</a>
</body>
</html>

prize.html：

<p th:text="${prize.description}"></p>
<a th:href="@{/}">Back to List</a>
</body>
</html>

new_prize.html：

        <label for="image">Image:</label>
        <input type="file" id="image" name="image">
    </div>
    <button type="submit">Save</button>
</form>
<a th:href="@{/}">Back to List</a>
</body>
</html>

edit_prize.html：

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">

    <meta charset="UTF-8">

    <button type="submit">Update</button>

这样，我们就完成了奖品表的管理功能。如果您需要更详细的代码，请告诉我。
