用spring boot框架设计一款工时管理系统，生产工程与代码

好的，我来给您设计一款基于 Spring Boot 的工时管理系统。

首先，我们需要确定该系统的功能模块。一般来说，一款工时管理系统需要包含以下模块：

1.用户管理模块：包括用户登录、注册、密码重置等功能。

2.项目管理模块：包括项目的创建、修改、删除等功能。

3.任务管理模块：包括任务的创建、修改、删除等功能。

4.工时管理模块：包括工时的录入、查询、统计等功能。

5.报表管理模块：包括报表的生成、导出等功能。

6.权限管理模块：包括用户权限的管理等功能。

接下来，我们可以开始编写代码。首先，创建一个 Spring Boot 项目，并添加相关的依赖项，如 Spring MVC、Spring Data JPA、Thymeleaf 等。

在项目中创建实体类，如 User、Project、Task、TimeSheet 等。这些实体类用于映射数据库中的表，同时还需要编写对应的 Repository 接口，用于实现对数据库的增删改查操作。

然后，我们编写控制器类，用于处理用户请求。在控制器类中，我们可以定义一些请求处理方法，如处理用户登录、注册、项目创建、任务创建等请求。在这些方法中，我们可以调用对应的 Service 层方法，实现相应的业务逻辑。

在 Service 层中，我们可以定义一些服务方法，如创建用户、创建项目、创建任务等。在这些方法中，我们可以调用对应的 Repository 接口方法，实现对数据库的操作。

最后，我们可以编写视图模板，如登录页面、首页、项目管理页面、任务管理页面等，这些视图模板用于呈现给用户进行交互。

具体的代码实现过程可以参考以下示例代码：

1. 实体类

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

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

    private String username;

    private String password;

    // getter 和 setter 方法
}

@Entity
@Table(name = "project")
public class Project {

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

    private String name;

    private Date startDate;

    private Date endDate;

    // getter 和 setter 方法
}

@Entity
@Table(name = "task")
public class Task {

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

    private String name;

    private String description;

    // getter 和 setter 方法
}

@Entity
@Table(name = "timesheet")
public class TimeSheet {

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

    private Long userId;

    private Long projectId;

    private Long taskId;

    private Date date;

    private Double hours;

    // getter 和 setter 方法
}

2. Repository 接口

public interface UserRepository extends JpaRepository<User, Long> {

    User findByUsername(String username);
}

public interface ProjectRepository extends JpaRepository<Project, Long> {

}

public interface TaskRepository extends JpaRepository<Task, Long> {

}

public interface TimeSheetRepository extends JpaRepository<TimeSheet, Long> {

    List<TimeSheet> findByUserIdAndDateBetween(Long userId, Date startDate, Date endDate);
}

3. Service 层

@Service
public class UserService {

    @Autowired
    private UserRepository userRepository;

    public User findByUsername(String username) {
        return userRepository.findByUsername(username);
    }

    public User createUser(User user) {
        return userRepository.save(user);
    }
}

@Service
public class ProjectService {

    @Autowired
    private ProjectRepository projectRepository;

    public Project createProject(Project project) {
        return projectRepository.save(project);
    }

    public List<Project> findAllProjects() {
        return projectRepository.findAll();
    }
}

@Service
public class TaskService {

    @Autowired
    private TaskRepository taskRepository;

    public Task createTask(Task task) {
        return taskRepository.save(task);
    }

    public List<Task> findAllTasks() {
        return taskRepository.findAll();
    }
}

@Service
public class TimeSheetService {

    @Autowired
    private TimeSheetRepository timeSheetRepository;

    public List<TimeSheet> findByUserIdAndDateBetween(Long userId, Date startDate, Date endDate) {
        return timeSheetRepository.findByUserIdAndDateBetween(userId, startDate, endDate);
    }

    public TimeSheet createTimeSheet(TimeSheet timeSheet) {
        return timeSheetRepository.save(timeSheet);
    }
}

4. 控制器类

@Controller
public class UserController {

    @Autowired
    private UserService userService;

    @GetMapping("/login")
    public String login() {
        return "login";
    }

    @PostMapping("/login")
    public String doLogin(String username, String password, HttpSession session) {
        User user = userService.findByUsername(username);
        if (user != null && user.getPassword().equals(password)) {
            session.setAttribute("user", user);
            return "redirect:/";
        } else {
            return "login";
        }
    }

    @GetMapping("/register")
    public String register() {
        return "register";
    }

    @PostMapping("/register")
    public String doRegister(User user) {
        userService.createUser(user);
        return "redirect:/login";
    }

    @GetMapping("/logout")
    public String logout(HttpSession session) {
        session.invalidate();
        return "redirect:/login";
    }
}

@Controller
public class ProjectController {

    @Autowired
    private ProjectService projectService;

    @GetMapping("/project")
    public String project(Model model) {
        List<Project> projects = projectService.findAllProjects();
        model.addAttribute("projects", projects);
        return "project";
    }

    @PostMapping("/project")
    public String createProject(Project project) {
        projectService.createProject(project);
        return "redirect:/project";
    }
}

@Controller
public class TaskController {

    @Autowired
    private TaskService taskService;

    @GetMapping("/task")
    public String task(Model model) {
        List<Task> tasks = taskService.findAllTasks();
        model.addAttribute("tasks", tasks);
        return "task";
    }

    @PostMapping("/task")
    public String createTask(Task task) {
        taskService.createTask(task);
        return "redirect:/task";
    }
}

@Controller
public class TimeSheetController {

    @Autowired
    private TimeSheetService timeSheetService;

    @GetMapping("/timesheet")
    public String timeSheet(Model model, HttpSession session) {
        User user = (User) session.getAttribute("user");
        if (user != null) {
            List<TimeSheet> timeSheets = timeSheetService.findByUserIdAndDateBetween(user.getId(), new Date(), new Date());
            model.addAttribute("timeSheets", timeSheets);
        }
        return "timesheet";
    }

    @PostMapping("/timesheet")
    public String createTimeSheet(TimeSheet timeSheet) {
        timeSheetService.createTimeSheet(timeSheet);
        return "redirect:/timesheet";
    }
}

5. 视图模板

以上是一个简单的工时管理系统的设计和实现过程。当然，其中还有很多细节需要根据实际需求进行调整和完善。
