我使用 MySQL 创建了一个用户表，关键字有user_id、user_name、account、password 、phone 、address 、role，请使用 springboot+hibernate+thymeleaf 帮我完成分页查询所有用户的功能，查询到的结果返回user-check.html，包含Controller、DAO、Entity、Service

好的，以下是示例代码。

首先是 Entity 类：

@Entity
@Table(name = "user")
public class User {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long user_id;

    private String user_name;

    private String account;

    private String password;

    private String phone;

    private String address;

    private String role;

    // 省略 getter 和 setter 方法
}

然后是 DAO 层：

@Repository
public interface UserRepository extends JpaRepository<User, Long> {

}

接下来是 Service 层：

@Service
public class UserService {

    @Autowired
    private UserRepository userRepository;

    public List<User> getAllUsers() {
        return userRepository.findAll();
    }

    public Page<User> getUsersByPage(int pageNum, int pageSize) {
        Pageable pageable = PageRequest.of(pageNum - 1, pageSize);
        return userRepository.findAll(pageable);
    }
}

最后是 Controller 层：

@Controller
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("/user/check")
    public String checkUsers(Model model, @RequestParam(defaultValue = "1") int pageNum,
                             @RequestParam(defaultValue = "10") int pageSize) {

        Page<User> users = userService.getUsersByPage(pageNum, pageSize);
        model.addAttribute("users", users.getContent());
        model.addAttribute("currentPage", users.getNumber() + 1);
        model.addAttribute("totalPages", users.getTotalPages());

        return "user-check";
    }
}

在 Thymeleaf 模板文件 user-check.html 中，可以使用类似如下的代码来显示查询到的用户列表：

<table>
    <thead>
        <tr>
            <th>user_id</th>
            <th>user_name</th>
            <th>account</th>
            <th>password</th>
            <th>phone</th>
            <th>address</th>
            <th>role</th>
        </tr>
    </thead>
    <tbody>
        <tr th:each="user : ${users}">
            <td th:text="${user.user_id}"></td>
            <td th:text="${user.user_name}"></td>
            <td th:text="${user.account}"></td>
            <td th:text="${user.password}"></td>
            <td th:text="${user.phone}"></td>
            <td th:text="${user.address}"></td>
            <td th:text="${user.role}"></td>
        </tr>
    </tbody>
</table>

<div>
    <ul class="pagination">
        <li th:class="${currentPage == 1} ? disabled : ''">
            <a th:href="@{/user/check(pageNum=1,pageSize=${pageSize})}" aria-label="First">
                <span aria-hidden="true">&laquo;</span>
            </a>
        </li>
        <li th:class="${currentPage == 1} ? disabled : ''">
            <a th:href="@{/user/check(pageNum=${currentPage - 1},pageSize=${pageSize})}" aria-label="Previous">
                <span aria-hidden="true">&lt;</span>
            </a>
        </li>
        <li th:class="${currentPage == totalPages} ? disabled : ''">
            <a th:href="@{/user/check(pageNum=${currentPage + 1},pageSize=${pageSize})}" aria-label="Next">
                <span aria-hidden="true">&gt;</span>
            </a>
        </li>
        <li th:class="${currentPage == totalPages} ? disabled : ''">
            <a th:href="@{/user/check(pageNum=${totalPages},pageSize=${pageSize})}" aria-label="Last">
                <span aria-hidden="true">&raquo;</span>
            </a>
        </li>
    </ul>
</div>

以上就是使用 Spring Boot、Hibernate 和 Thymeleaf 实现分页查询所有用户的示例代码了。
