期末考试还缺项目吗？黑马的图书借阅管理系统很香

提示：黑马程序员的云借阅管理系统, 后端ssm框架, 前端jQuery, layui,模板引擎为thymeleaf。 有需要的小伙伴可以三连, 我会私聊你发源码。

提示：管理员全部功能, 用户部分功能

一、整个项目功能图

二、代码展示

1. 用户模块

登录分为管理员登录, 普通用户登录, 不同身份登录拥有的权限也不同

代码

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


    @Autowired
    private UserService userService;

    /**
     * to -> 登录功能
     * localhost:8081/pub/user/toLogin
     * @return
     */
    @GetMapping("toLogin")
    public String toLogin(){
        return "login";
    }

    /**
     * 登录功能
     * localhost:8081/pub/user/login
     * @param email
     * @param pwd
     * @param model
     * @return
     */
    @PostMapping("login")
    public String login(String email, String pwd, Model model, HttpServletRequest request){
        //从数据库中查找用户
        User user = userService.login(email,pwd);
        if(user == null){
            //没有该账户
            model.addAttribute("userLoginMsg", "账户密码错误");
            return "login";  //重新登录
        }else {
            if ("0".equals(user.getUserStatus())){  //判断是否是正常用户
                //将用户存储到session中
                request.getSession().setAttribute("user",user);
                return "redirect:/pri/book/list_book";     //进入管理员界面
            }else{   //用户被冻结
                //不是正常用户
                model.addAttribute("userLoginMsg", "账号已经冻结");
                return "login";  //重新登录
            }
        }
    }

    /**
     * 退出登录
     * localhost:8081/pub/user/layout
     * @param request
     * @return
     */
    @GetMapping("layout")
    public String layout(HttpServletRequest request){
        //清口session会话
        request.getSession().invalidate();
        return "redirect:/pub/user/toLogin";
    }
}

2. 书籍模块

首页页面

借阅图书页面

当前借阅页面

代码

@Controller
@RequestMapping("/pri/book")
public class BookController {

    @Autowired
    private BookService bookService;
    /**
     * 分页查询书籍功能
     * localhost:8081/pri/book/list_book?pageNum=2
     * @param pageNum
     * @param pageSize
     * @param model
     * @return
     */
    @GetMapping("list_book")
    public String listBook(@RequestParam(value = "pageNum", required = false, defaultValue = "1") Integer pageNum,
                           @RequestParam(value = "pageSize", required = false, defaultValue = "5") Integer pageSize,
                           Model model){
        //查询数据库记录
        List<Book> list = bookService.listBook(pageNum,pageSize);
        //查询数据库书籍的总记录数
        Integer totalRecordNum = bookService.findBookTotalNum();
        //将书籍存储起来, 传给前端页面
        model.addAttribute("bookList", list);
        //计算总页数
        Integer totalPage = 0;
        if(totalRecordNum % pageSize == 0){ //刚好满足
            totalPage  = totalRecordNum / pageSize;
        }else{ //比满页多一页
            totalPage  = totalRecordNum / pageSize + 1;
        }
        model.addAttribute("totalPage",totalPage); //将数据存储起来
        return "welcome";
    }

    /**
     * 跳转到借阅信息当中
     * localhost:8081/pri/book/to_book_borrow
     * @return
     */
    @GetMapping("to_book_borrow")
    public String toBookBorrow(Model model,HttpServletRequest request){
        //收集从前端传来的代码
        Integer bookId = Integer.parseInt(request.getParameter("book_id"));
        //通过book的id去查找Book信息
        Book book = bookService.findBookById(bookId);
        //将信息存储起来
        model.addAttribute("book", book);
        System.out.println("===========" + book.toString());
        return "bookDetail";
    }

    /**
     * 图书借阅功能
     * localhost:8081/pri/book/borrow_book
     * @param book
     * @param request
     * @param model
     * @return
     */
    @PostMapping("borrow_book")
    public String borrowBook(Book book,HttpServletRequest request,Model model){
        System.out.println("===========" + book.toString());
        //从session中获取user信息
        User user = (User)request.getSession().getAttribute("user");
        String userName = user.getUserName();
        //更新数据库书籍状态
        Integer flag = bookService.borrowBook(book,userName);
        if (flag > 0){ //更新成功 -> 借阅成功
            model.addAttribute("borrowBookMsg", "借阅成功,请到图书馆二楼领取");
            return "redirect:/pri/book/list_book";
        }
        model.addAttribute("borrowBookMsg", "借阅失败,请重试该操作");
        return "redirect:/pri/book/list_book";
    }
}

3. 拦截器配置

为什么要配置拦截器？

拦截器可以避免一些错误, 比如借阅图书的时候需要获取用户的信息,

如果程序里面的session没用user信息, 则不能访问页面。

未登录的效果展示

代码

1. 配置

//能够被springIOC容器扫描到
@Configuration
public class InterceptorConfig implements WebMvcConfigurer {

    private LoginInterceptor loginInterceptor;

    @Autowired
    public void setLoginInterceptor(LoginInterceptor loginInterceptor){
        this.loginInterceptor = loginInterceptor;
    }

    /**
     * 添加拦截器
     * @param registry
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(loginInterceptor).addPathPatterns("/**").
                excludePathPatterns("/pub/user/login","/","/pub/user/toLogin", "/pub/user/layout");
    }
}

2. 拦截器

@Component
public class LoginInterceptor implements HandlerInterceptor {

    /**
     * 获取session会话,然后验证session会话是否有user,有放行, 没有则通过
     * @param request
     * @param response
     * @param handler
     * @return
     * @throws Exception
     */
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

        HttpSession session = request.getSession();
        User user = (User)session.getAttribute("user");
        if(user != null){
            return true;
        }
        return false;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {

    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {

    }
}
