41 | ## MVC设计模式
42 |
43 | ### M（model层）
44 |
45 | 1. biz包：业务处理。
46 | 2. dao包：数据访问，对数据库的一些封装操作。
47 | 3. entity包：实体类，javabean构建，View层和数据库之间的桥梁作用。
48 |
49 | ### V（view层）
50 |
51 | 1. Jsp页面：与用户进行交互的界面。
52 |
53 | 
54 |
55 | ### C（controller 层）
56 |
57 | 1. servlet包：控制层，处理View层Jsp页面发来的请求。
58 |
59 | ## 注册登录模块
60 |
61 | ### Register
62 |
63 | 
64 |
65 | **注册页面中form表单**
66 |
67 | 验证用户名、验证密码、验证邮箱
68 |
69 | ```jsp
70 |
84 | ```
85 |
86 | **Ajax（异步 JavaScript 和 XML ）**：验证用户名是否已被注册，页面部分数据刷新，而无需加载整个网页，提高网站的访问效率。
87 |
88 | ```javascript
89 | /**
90 | * Ajax检查用户是否已经被注册
91 | * 异步：发送请求时不等返回结果，由回调函数处理结果
92 | * @returns {Boolean}
93 | */
94 | function isExists() {
95 | var xmlHttp; //定义 xmlHttp XmlHttpRequest对象从服务器异步获取数据后通过javascript修改页面局部信息
96 | try {
97 | //根据不同浏览器初始化不同的xmlHttp浏览器对象
98 | //IE6以上浏览器
99 | xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
100 | } catch (e) {
101 | try {
102 | //FireFox
103 | xmlHttp = new XMLHttpRequest();
104 | } catch (e) {
105 | try {
106 | //IE5.5+
107 | xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
108 | } catch (e) {
109 | alert("您的浏览器不支持Ajax");
110 | return false;
111 | }
112 | }
113 | }
114 | var username = document.getElementById("username").value; //获取用户名
115 | /**
116 | * open(提交方式[get|post]，url（servlet路径），同步或异步[false|true])
117 | * RegisterServlet： servlet路径
118 | * 打开和后台服务器的链接
119 | */
120 | xmlHttp.open("POST", "RegisterServlet?action=check&username="+username, true); //路径中不能有空格
121 | xmlHttp.send(null); //传送数据
122 | /**
123 | * onreadystatechange:调用回调函数
124 | * readyState：请求状态，代码是未初始化，1：初始化，2：发送请求，3：开始接受数据，4：接受结果完毕
125 | * status: http状态码 200成功，404路径错误，500后台代码错误,
126 | */
127 | xmlHttp.onreadystatechange = function() {
128 | if(xmlHttp.readyState==4 && xmlHttp.status==200) {
129 | var usernull = document.getElementById("usernull");
130 | var result = xmlHttp.responseText; //接受服务器端传过来的数据，写出来的数据都是String类型
131 | if(result == "true") {
132 | usernull.innerHTML = "当前用户名已被注册";
133 | return false;
134 | } else if(result == "false") {
135 | usernull.innerHTML = "当前用户名可用";
136 | return true;
137 | }
138 | }
139 | }
140 | }
141 | ```
142 |
143 |
144 |
145 | ### Login
146 |
147 | 
148 |
149 | **LoginServlet中doGet方法：**
150 |
151 | ```java
152 | protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
153 | String username = request.getParameter("username");//获取页面传过来的参数
154 | String password = request.getParameter("password");
155 | //登录操作
156 | boolean flag = userBiz.checkLogin(username, password);
157 |
158 | if(flag) {
159 | request.getSession().setAttribute("loginuser", username);
160 | // response.sendRedirect("main.jsp");
161 | response.sendRedirect("SearchServlet"); //首页直接显示
162 | } else {//登录失败
163 | response.setContentType("text/html;charset=utf-8");
164 | // response.setCharacterEncoding("utf-8");
165 | PrintWriter out = response.getWriter();
166 | out.println("");
170 | out.close();
171 | }
172 | }
173 | ```
174 |
175 |
176 |
177 | ## 网站首页及搜索图书模块
178 |
179 | 
180 |
181 |
182 |
183 | ### **分页展示**
184 |
185 | Jstl标签库 c：forEach，循环遍历展示图书信息。
186 |
187 | ```jsp
188 |
150 |
186 |
187 |
208 | 首页
209 | <%for(int i = 1; i <= totalPage; i++) { %>
210 | <%if(i==no) { %>
211 | <%=i %>
212 | <%continue;} %>
213 | <%=i %>
214 | <%} %>
215 | 尾页
216 |
217 |
218 | <%} %>
219 |
220 | ```
221 |
222 | **servlet处理**
223 |
224 | ```java
225 | protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
226 | request.setCharacterEncoding("utf-8");
227 |
228 | String currentPage = request.getParameter("currentPage");//获取当前页
229 | int no = currentPage == null?1:Integer.parseInt(currentPage);//如果当前页为空，则默认为1，否则转化为相应的int
230 |
231 | // String currentSearchPage = request.getParameter("currentSearchPage");
232 | String bookname = request.getParameter("keywords");//获取你输入的书名
233 | List
