温馨提示本人主页置顶文章(点我)开头有 CSDN 平台官方提供的学长联系方式的名片技术栈后端框架Spring Boot 2.x提供快速开发、自动配置和嵌入式Tomcat支持。数据库MySQL 8.0用于存储民宿、用户、订单等数据。持久层MyBatis或JPA用于数据库操作。前端技术Thymeleaf/Vue.js Element UI实现动态页面和交互。安全框架Spring Security处理用户认证和授权。缓存Redis用于高频访问数据如热门民宿信息的缓存。消息队列RabbitMQ处理异步任务如订单超时取消。支付集成支付宝/微信支付SDK实现在线支付功能。背景与意义行业需求民宿行业快速发展传统手工管理效率低需数字化系统提升运营效率。用户体验在线预订、支付、评价等功能整合提升用户便捷性。数据分析通过订单和用户行为数据优化房源管理和营销策略。核心代码示例1. 民宿预订接口Spring Boot MyBatisRestController RequestMapping(/api/booking) public class BookingController { Autowired private BookingService bookingService; PostMapping(/create) public Result createBooking(RequestBody BookingDTO bookingDTO) { return bookingService.createBooking(bookingDTO); } GetMapping(/list/{userId}) public Result listBookings(PathVariable Long userId) { return bookingService.listByUserId(userId); } }2. 支付回调处理PostMapping(/pay/callback) public String handlePaymentCallback(RequestBody String callbackData) { if (paymentService.verifySignature(callbackData)) { paymentService.updateOrderStatus(callbackData); return success; } return fail; }3. Spring Security配置Configuration EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers(/api/user/**).hasRole(USER) .antMatchers(/api/admin/**).hasRole(ADMIN) .and() .formLogin() .loginPage(/login); } }数据库设计1. 用户表userCREATE TABLE user ( id BIGINT PRIMARY KEY AUTO_INCREMENT, username VARCHAR(50) UNIQUE NOT NULL, password VARCHAR(100) NOT NULL, phone VARCHAR(20), role ENUM(USER, ADMIN) DEFAULT USER );2. 民宿表homestayCREATE TABLE homestay ( id BIGINT PRIMARY KEY AUTO_INCREMENT, name VARCHAR(100) NOT NULL, address TEXT NOT NULL, price DECIMAL(10,2) NOT NULL, status ENUM(AVAILABLE, BOOKED) DEFAULT AVAILABLE );3. 订单表bookingCREATE TABLE booking ( id BIGINT PRIMARY KEY AUTO_INCREMENT, user_id BIGINT NOT NULL, homestay_id BIGINT NOT NULL, start_date DATE NOT NULL, end_date DATE NOT NULL, total_price DECIMAL(10,2) NOT NULL, status ENUM(PENDING, PAID, CANCELLED) DEFAULT PENDING, FOREIGN KEY (user_id) REFERENCES user(id), FOREIGN KEY (homestay_id) REFERENCES homestay(id) );4. 支付记录表paymentCREATE TABLE payment ( id BIGINT PRIMARY KEY AUTO_INCREMENT, booking_id BIGINT NOT NULL, amount DECIMAL(10,2) NOT NULL, transaction_id VARCHAR(100), status ENUM(SUCCESS, FAILED, PENDING), FOREIGN KEY (booking_id) REFERENCES booking(id) );关键点说明事务管理使用Transactional确保订单创建与支付状态的原子性。缓存应用Redis缓存热门民宿列表减少数据库压力。安全性密码加密存储BCrypt支付接口签名验证。扩展性表结构设计支持未来新增字段如民宿标签、用户积分等。
