@RequestMapping("/list") public String list(@RequestParam(name = "page", defaultValue = "1") Integer pageNum, String content, Model model, HttpSession session) { String userId = session.getAttribute("id").toString(); User user = userDao.findById(userId).get(); MongoPageAble mongoPageAble = MongoPageAble.of(pageNum, 10000); Query query = new Query(); query.with(mongoPageAble); if (StrUtil.isNotBlank(content)) { Pattern pattern = Pattern.compile("^.*" + content + ".*$", Pattern.CASE_INSENSITIVE); query.addCriteria(Criteria.where("content").regex(pattern)); } if (user.getRoleId().equals("1")){ query.addCriteria(Criteria.where("userId").regex(userId)); } query.with(Sort.by(Sort.Direction.DESC, "createTime")); Page<Maintenance> page = MongoPageUtil.findPage(query, mongoPageAble, Maintenance.class, mongoTemplate); List<Maintenance> lists = page.getContent(); for (int i = 0; i < lists.size(); i++) { Maintenance maintenance = lists.get(i); try { String id = maintenance.getHouseId(); House house = houseDao.findById(id).get(); maintenance.setHouseId(house.getName()); }catch (Exception e){ maintenance.setHouseId("房产已删除"); } } model.addAttribute("list", page); return "maintenance/list"; }解释

这是一个Java Spring MVC的请求映射方法，用于处理“/list”页面的GET请求。这个方法有多个参数：

- pageNum：页码，表示要显示第几页的内容，默认值为1；
- content：查询关键字，用于搜索内容；
- model：用于存储视图中要显示的数据；
- session：用于获取当前用户的信息。

这个方法首先从session中获取当前用户的id，然后根据id查询到对应的User对象。接下来，使用MongoPageUtil提供的工具类进行MongoDB分页查询，查询条件包括：

- 如果content不为空，则根据content查询；
- 如果当前用户的roleId为1，则只查询该用户发布的维修信息。

最后，将查询到的维修信息列表封装到Page对象中，并将Page对象存储到model中，最终返回“maintenance/list”视图页面。在获取维修信息列表之前，还对每条维修信息中的houseId进行了处理，如果查询到对应的房产信息，则将houseId替换为房产名称，否则将houseId替换为“房产已删除”。

我使用 MySQL 创建了一个用户表TbUser，userId的类型为Integer，并且使用@GetMapping("/alterListUsers") public String alterListUsers(@RequestParam(defaultValue = "1") int pageNum, Model model) { Page<TbUser> page = tbUserService.findUsers(pageNum); List<TbUser> userList = page.getContent(); model.addAttribute("userList", userList); model.addAttribute("currentPage", pageNum); model.addAttribute("totalPages", page.getTotalPages()); return "management/user-alter"; }完成了用户分页查询功能，查询的结果返回了user-alter.html，请使用springboot+hibernate+thymeleaf帮助我完成编辑用户的功能，点击编辑按钮后，弹窗一个表单可以修改用户所有信息，点击确定后将信息保存到数据库，包含DAO、Controller、Entity、Service、impl的详细代码

好的，下面是对应的代码：

    // 省略getter和setter方法
}

@Repository
public interface TbUserRepository extends JpaRepository<TbUser, Integer> {

我使用 MySQL 创建了一个用户表TbUser，userId类型为Integer，并且使用@GetMapping("/deleteListUsers") public String deleteListUsers(@RequestParam(defaultValue = "1") int pageNum, Model model) { Page<TbUser> page = tbUserService.findUsers(pageNum); List<TbUser> userList = page.getContent(); model.addAttribute("userList", userList); model.addAttribute("currentPage", pageNum); model.addAttribute("totalPages", page.getTotalPages()); return "management/user-delete"; }完成了用户分页查询功能，查询的结果返回了user-delete.html，请帮使用springboot+hibernate+thymeleaf帮助我完删除单个用户的功能，删除操作不做物理删除，只做逻辑删除（0表示未删除，1表示已删除），使用逻辑删除标识列status来记录，包含DAO、Controller、Entity、Service、impl

好的，以下是你所需要的代码：

TbUser Entity类

@Entity
@Table(name = "TbUser")
public class TbUser {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer userId;
    private String username;
    private String password;
    private Integer status;

    // 省略getter和setter方法
}

TbUser DAO接口

@Repository
public interface TbUserDao extends JpaRepository<TbUser, Integer> {
    Page<TbUser> findAllByStatus(Integer status, Pageable pageable);
}

TbUser Service接口

public interface TbUserService {
    Page<TbUser> findUsers(int pageNum);

    void logicDeleteUser(Integer userId);
}

TbUser Service实现类

@Service
public class TbUserServiceImpl implements TbUserService {

    @Autowired
    private TbUserDao tbUserDao;

    @Override
    public Page<TbUser> findUsers(int pageNum) {
        Pageable pageable = PageRequest.of(pageNum - 1, 10); // 每页显示10条记录
        return tbUserDao.findAllByStatus(0, pageable); // 查询未删除的用户
    }

    @Override
    @Transactional(rollbackFor = Exception.class)
    public void logicDeleteUser(Integer userId) {
        TbUser tbUser = tbUserDao.findById(userId).orElse(null);
        if (tbUser != null) {
            tbUser.setStatus(1); // 将用户的状态设置为已删除
            tbUserDao.save(tbUser);
        }
    }
}

Controller类

@Controller
@RequestMapping("/user")
public class UserController {

    @Autowired
    private TbUserService tbUserService;

    @GetMapping("/deleteListUsers")
    public String deleteListUsers(@RequestParam(defaultValue = "1") int pageNum, Model model) {
        Page<TbUser> page = tbUserService.findUsers(pageNum);
        List<TbUser> userList = page.getContent();
        model.addAttribute("userList", userList);
        model.addAttribute("currentPage", pageNum);
        model.addAttribute("totalPages", page.getTotalPages());
        return "management/user-delete";
    }

    @GetMapping("/deleteUser/{id}")
    public String deleteUser(@PathVariable("id") Integer userId) {
        tbUserService.logicDeleteUser(userId);
        return "redirect:/user/deleteListUsers";
    }
}

在user-delete.html中添加删除按钮

<table>
    <thead>
        <tr>
            <th>用户ID</th>
            <th>用户名</th>
            <th>操作</th>
        </tr>
    </thead>
    <tbody>
        <tr th:each="user : ${userList}">
            <td th:text="${user.userId}"></td>
            <td th:text="${user.username}"></td>
            <td>
                <a th:href="@{/user/deleteUser/{id}(id=${user.userId})}">删除</a>
            </td>
        </tr>
    </tbody>
</table>

以上代码实现了逻辑删除单个用户的功能，当点击删除按钮后，会将该用户的状态设置为已删除，并重定向到用户列表页面。
