通配符映射示例(3):<br>
<a href="${pageContext.request.contextPath}/pattern/BookAction_add.action">图书添加</a><br>
<a href="${pageContext.request.contextPath}/pattern/BookAction_delete.action">图书删除</a><br>

动态方法调用!形式:<br>
<a href="${pageContext.request.contextPath}/pattern/BookAction!add.action">图书添加</a><br>
<a href="${pageContext.request.contextPath}/pattern/BookAction!delete.action">图书删除</a><br>


<br><br>
使用通配符定义action<br>
<a href="${pageContext.request.contextPath}/pattern/BookAction_add.action">图书添加</a><br>
<a href="${pageContext.request.contextPath}/pattern/BookAction_delete.action">图书删除</a><br>

（一）项目构建 使用 Maven 构建项目，在pom.xml中引入 Spring MVC 相关依赖，如spring - webmvc，配置 Servlet、JSP 等相关依赖，确保项目具备 Spring MVC 运行环境 。示例关键依赖配置： <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring - webmvc</artifactId> <version>5.3.18</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet - api</artifactId> <version>4.0.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp - api</artifactId> <version>2.3.3</version> <scope>provided</scope> </dependency> <!-- 其他如JSTL等依赖按需添加 --> </dependencies> （二）Spring MVC 配置 DispatcherServlet 配置：在 Web.xml（或 Servlet 3.0 + 环境下用 Java 配置）中配置 DispatcherServlet，指定 Spring MVC 配置文件位置，使其能拦截处理请求 。示例 Web.xml 配置： <servlet> <servlet - name>springmvc</servlet - name> <servlet - class>org.springframework.web.servlet.DispatcherServlet</servlet - class> <init - param> <param - name>contextConfigLocation</param - name> <param - value>classpath:springmvc - servlet.xml</param - value> </init - param> <load - on - startup>1</load - on - startup> </servlet> <servlet - mapping> <servlet - name>springmvc</servlet - name> <url - pattern>/</url - pattern> </servlet - mapping> Spring MVC 配置文件（springmvc - servlet.xml）：开启组件扫描（扫描控制器等组件）、视图解析器（配置前缀后缀，解析 JSP 视图）、开启注解驱动等 。示例： <context:component - scan base - package="com.example.controller"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB - INF/views/"/> <property name="suffix" value=".jsp"/> </bean> <mvc:annotation - driven/> 三）功能模块实现 1. 用户登录验证 o 控制器（Controller）：创建LoginController，编写方法处理/login请求（对应login.jsp表单提交），接收用户名、密码参数（可通过@RequestParam注解），进行简单验证（如硬编码用户名 “admin”、密码 “123” 模拟，实际可连数据库查询），验证成功用return "redirect:/main";重定向到主页控制器方法，失败则带错误信息（通过model.addAttribute）返回login视图（即login.jsp ）。示例代码： package com.example.controller; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; @Controller public class LoginController { @RequestMapping("/login") public String login(@RequestParam("username") String username, @RequestParam("password") String password, Model model) { if ("admin".equals(username) && "123".equals(password)) { return "redirect:/main"; } else { model.addAttribute("error", "用户名或密码错误"); return "login"; } } 2. 登录页面（login.jsp）：使用 Spring 表单标签库（需引入相关标签库）或普通 HTML 表单，提交到/login，显示错误信息（通过 EL 表达式${error} ）。示例关键代码： <%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %> <html> <body> <form:form action="/login" method="post"> 用户名：<form:input path="username"/><br> 密码：<form:password path="password"/><br> <input type="submit" value="登录"> </form:form> <c:if test="${not empty error}"> <p style="color:red">${error}</p> </c:if> </body> </html> 3. 访问控制（拦截器实现） o 创建拦截器类：实现HandlerInterceptor接口，在preHandle方法中检查会话是否有用户登录标识（如session.getAttribute("user") ，假设登录成功时在会话存user对象），无则redirect到/login并返回false拦截，有则返回true放行 。示例： package com.example.interceptor; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.HandlerInterceptor; public class LoginInterceptor implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { Object user = request.getSession().getAttribute("user"); if (user == null) { response.sendRedirect(request.getContextPath() + "/login"); return false; } return true; } } 4. 配置拦截器：在 Spring MVC 配置文件（springmvc - servlet.xml）中注册拦截器，指定拦截路径（如/main ）。示例： <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/main"/> <bean class="com.example.interceptor.LoginInterceptor"/> </mvc:interceptor> </mvc:interceptors> 5. 会话管理（登出功能） o 控制器方法：在MainController中编写处理登出的方法，调用session.invalidate()销毁会话，然后redirect到登录页 。示例： package com.example.controller; import javax.servlet.http.HttpSession; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class MainController { @RequestMapping("/main") public String main() { return "main"; } @RequestMapping("/logout") public String logout(HttpSession session) { session.invalidate(); return "redirect:/login"; } } 6. 主页（main.jsp）：添加 “退出” 链接， href 指向/logout 。示例： <html> <body> <h1>欢迎访问主页</h1> <a href="${pageContext.request.contextPath}/logout">退出</a> </body> </html>
