![image](https://github.com/codeYoke/my-picture/blob/master/bookStore/book4.gif) 263 | 264 | **注意：** 265 | 266 | 当库存不足时，防止库存数被减到负值。 267 | 268 | ```java 269 | if(oneStock > 0) {//如果库存大于0 270 |

void remove(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 335 | //1.获取图书id 336 | String bid = request.getParameter("bid"); 337 | //2.获取购物车 338 | List bookcart = (List) request.getSession().getAttribute("bookcart"); 339 | //3.循环查找购物车中相同的图书id 340 | for(int i = 0; i< bookcart.size(); i++) { 341 | Book book = bookcart.get(i); 342 | if(Integer.valueOf(bid) == book.getBid()) { 343 | //4.移除图书 344 | bookcart.remove(i); 345 | //5.修改库存 346 | bookbiz.changeStock(Integer.parseInt(bid), book.getCount()+""); 347 | break; 348 | } 349 | } 350 | 351 | //6.将购物车保存到session中 352 | // request.getSession().setAttribute("bookcart", bookcart); 353 | request.getSession().setAttribute("bookcart_count", bookcart.size()); 354 | System.out.println(request.getSession().getAttribute("bookcart_count")); 355 | } 356 | ``` 357 | 358 | 359 | 360 | ### 改 361 | 362 | 1. **前端shopping.jsp页面，添加onblur失去焦点事件，当鼠标离开输入框时执行JavaScript代码，调用update方法。** 363 | 364 | ```jsp 365 | 366 | 367 | 368 | 370 | 371 | ${book.bookname } 372 | 374 | 376 | ￥ 377 | 378 | 移除 379 | 380 | 381 | 382 | ``` 383 | 384 | 2. **异步更新图书购买量数据，并向控制层Servlet中返回一个“update”** 385 | 386 | ```javascript 387 | /** 388 | * Ajax修改购物车中的数量 389 | */ 390 | function update(size_str, i, bid_str) { 391 | //初始化XMLHttpRequest对象 392 | var xmlHttp; 393 | try { 394 | xmlHttp = new ActiveXObject("Msxml2.XMLHTTP"); 395 | } catch (e) { 396 | try { 397 | xmlHttp = new XMLHttpRequest(); 398 | } catch (e) { 399 | try { 400 | xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); 401 | } catch (e) { 402 | e.message(); 403 | alert("你的浏览器不支持Ajax"); 404 | } 405 | } 406 | } 407 | //2.获取修改后的数量 408 | var num_str = document.getElementById("nums_"+i); 409 | //3.打开服务器链接 410 | xmlHttp.open("POST", "ModifyCartServlet?action=update&bid="+bid_str+"&count="+num_str.value, true); 411 | //4.传值 ，无参传null值 412 | xmlHttp.send(null); 413 | //5.设置回调函数 414 | xmlHttp.onreadystatechange = function() { 415 | if(xmlHttp.readyState == 4 && xmlHttp.status == 200) { 416 | count(size_str);//调用Servlet中的方法 417 | } 418 | } 419 | } 420 | ``` 421 | 422 | 3. **servlet中通过前端返回的请求调用相应的方法。** 423 | 424 | ```java 425 | String action = request.getParameter("action"); 426 | if(action.equals("update")) { 427 | updateCart(request, response); 428 | } 429 | else if(action.equals("remove")) { 430 | remove(request, response); 431 | } 432 | ``` 433 | 434 | 4. **控制层Servlet更新购物车数据，并修改库存。** 435 | 436 | ```java 437 | protected void updateCart(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 438 | //1.获取图书id和修改后的数量 439 | String bid = request.getParameter("bid"); 440 | String count = request.getParameter("count"); 441 | //2.获取购物车 442 | List bookcart = (List) request.getSession().getAttribute("bookcart"); 443 | //3.查找购物车中修改过的图书，并修改相应的信息 444 | for (Book book : bookcart) { 445 | if(Integer.valueOf(bid) == book.getBid()) { 446 | //4.获取修改前的图书数量 447 | int old_count = book.getCount(); 448 | //5.设置当前图书的新数量 449 | book.setCount(Integer.valueOf(count)); 450 | System.out.println("当前图书新数量"+count); 451 | 452 | int nowStock = 0; 453 | try { 454 | nowStock = basedao.queryStock(Integer.parseInt(bid)); 455 | } catch (Exception e) { 456 | e.printStackTrace(); 457 | } 458 | 459 | //6.修改库存 460 | bookbiz.changeStock(Integer.parseInt(bid), (old_count-Integer.parseInt(count))+""); 461 | break; 462 | } 463 | } 464 | } 465 | ``` 466 | 467 | 468 | 469 | ### 查 470 | 471 | 与搜索图书模块类似 472 | 473 | 474 | 475 | ## 我的订单模块 476 | 477 | 1. 获取订单信息，存入List中 478 | 479 | ```java 480 | <% 481 | List orders = (List) request.getAttribute("orders"); 482 | %> 483 | ``` 484 | 485 | 2. 订单展示 486 | 487 | ```jsp 488 | 489 | 490 | ${order.oid } 491 | ${order.username } 492 | ${order.createdate } 493 | ${order.total_price } 494 | 495 | ${order.bookname } 496 | ${order.b_price } 497 | ${order.total_price/order.b_price } 498 | 499 | 500 | ``` 501 | 502 | 503 | 504 | ## 用户退出 505 | 506 | **当用户退出登录，清空session。** 507 | 508 | ```java 509 | <%--用户退出登录 --%> 510 | <% 511 | request.getSession().removeAttribute("loginuser"); 512 | request.getSession().removeAttribute("bookcart"); 513 | request.getSession().removeAttribute("bookcart_count"); 514 | response.sendRedirect("login.jsp"); 515 | %> 516 | ``` 517 | 518 | 519 | 520 | ## 一些注意细节 521 | 522 | 1. **为防止游客非法访问页面，在每一个前端页面body之后加上登录检测代码。** 523 | 524 | ```jsp 525 | <% 526 | String username = (String)session.getAttribute("loginuser"); 527 | if(username == null) { 528 | response.sendRedirect("login.jsp"); 529 | } 530 | %> 531 | ``` 532 | 533 | 2. **当库存不足时，防止库存数被减到负值。** 534 | 535 | ```java 536 | if(oneStock > 0) {//如果库存大于0 537 | //... 538 | } 539 | ``` 540 | 541 | 3. **href中加上空链接，否则该页面中的session不会刷新，必须手动刷新。** 542 | 543 | ```jsp 544 | 移除 545 | ``` 546 | 547 | 548 | ## 致谢 549 | 550 |
