概述

基于Spring + Spring MVC + MyBatis的图书馆管理系统，使用Maven进行包管理。主要功能包括：图书查询、图书管理、图书编辑、读者管理、图书的借阅与归还以及借还日志记录等。

代码

@Controller
public class LendController {
 @Autowired
 private LendService lendService;

 @Autowired
 private BookService bookService;

 @RequestMapping("/deletebook.html")
 public String deleteBook(HttpServletRequest request, RedirectAttributes redirectAttributes) {
 long bookId = Long.parseLong(request.getParameter("bookId"));
 if (bookService.deleteBook(bookId)) {
 redirectAttributes.addFlashAttribute("succ", "图书删除成功！");
 } else {
 redirectAttributes.addFlashAttribute("error", "图书删除失败！");
 }
 return "redirect:/admin_books.html";
 }

 @RequestMapping("/lendlist.html")
 public ModelAndView lendList(HttpServletRequest request) {
 ModelAndView modelAndView = new ModelAndView("admin_lend_list");
 modelAndView.addObject("list", lendService.lendList());
 return modelAndView;
 }

 @RequestMapping("/mylend.html")
 public ModelAndView myLend(HttpServletRequest request) {
 ReaderCard readerCard = (ReaderCard) request.getSession().getAttribute("readercard");
 ModelAndView modelAndView = new ModelAndView("reader_lend_list");
 modelAndView.addObject("list", lendService.myLendList(readerCard.getReaderId()));
 return modelAndView;
 }

 @RequestMapping("/deletelend.html")
 public String deleteLend(HttpServletRequest request, RedirectAttributes redirectAttributes) {
 long serNum = Long.parseLong(request.getParameter("serNum"));
 if (lendService.deleteLend(serNum) > 0) {
 redirectAttributes.addFlashAttribute("succ", "记录删除成功！");
 } else {
 redirectAttributes.addFlashAttribute("error", "记录删除失败！");
 }
 return "redirect:/lendlist.html";
 }

 @RequestMapping("/lendbook.html")
 public String bookLend(HttpServletRequest request, RedirectAttributes redirectAttributes) {
 long bookId = Long.parseLong(request.getParameter("bookId"));
 long readerId = ((ReaderCard) request.getSession().getAttribute("readercard")).getReaderId();
 if (lendService.lendBook(bookId, readerId)) {
 redirectAttributes.addFlashAttribute("succ", "图书借阅成功！");
 } else {
 redirectAttributes.addFlashAttribute("succ", "图书借阅成功！");
 }
 return "redirect:/reader_books.html";
 }

 @RequestMapping("/returnbook.html")
 public String bookReturn(HttpServletRequest request, RedirectAttributes redirectAttributes) {
 long bookId = Long.parseLong(request.getParameter("bookId"));
 long readerId = ((ReaderCard) request.getSession().getAttribute("readercard")).getReaderId();
 if (lendService.returnBook(bookId, readerId)) {
 redirectAttributes.addFlashAttribute("succ", "图书归还成功！");
 } else {
 redirectAttributes.addFlashAttribute("error", "图书归还失败！");
 }
 return "redirect:/reader_books.html";
 }
}

运行配置

1.首先安装Mysql5.7，设置用户名为root，密码为root，并保证其在运行状态，并执行library.sql文件导入数据。
2.然后再配置Maven到环境变量中，在源代码目录下运行

mvn jetty:run

3.使用浏览器访问http://localhost:8080即可进入系统。

概念设计

用户分为两类：读者、图书馆管理员。图书馆管理员可以修改读者信息，修改书目信息，查看所有借还日志等；读者仅可以修改个人信息、借阅或归还书籍和查看自己的借还日志。
