基于SpringBoot的宠物用品系统
MySQL 8.0主从架构，包含12个核心表：用户表（user_info）、商品表（product）、订单表（order_main）、评价表（comment）等。支持商品的CRUD操作，包含分类管理（如食品、玩具、清洁用品）、库存预警功能。采用Elasticsearch实现商品搜索，支持按价格、销量、评价等多维度排序。实现注册、登录、权限管理功能，采用Spring Security进行身份验证。集
核心功能模块设计
用户管理模块
实现注册、登录、权限管理功能，采用Spring Security进行身份验证。用户分为普通用户、商家和管理员三种角色，通过JWT生成Token保持会话状态。
商品管理模块
支持商品的CRUD操作，包含分类管理（如食品、玩具、清洁用品）、库存预警功能。采用Elasticsearch实现商品搜索，支持按价格、销量、评价等多维度排序。
订单处理模块
集成支付宝/微信支付SDK，包含购物车、订单状态跟踪（待付款/已发货/已完成）、退货流程。使用Redis缓存热门商品数据，减轻数据库压力。
技术架构选型
后端框架
SpringBoot 3.1 + MyBatis-Plus + Lombok，采用Maven多模块化设计。接口文档使用Swagger 3.0自动生成，数据库连接池选用HikariCP。
数据库设计
MySQL 8.0主从架构，包含12个核心表：用户表（user_info）、商品表（product）、订单表（order_main）、评价表（comment）等。建立商品分类的树形结构表（category）。
前端技术栈
Vue 3 + Element Plus构建管理后台，uniapp开发微信小程序端。采用axios进行异步请求，Vuex管理全局状态。
关键代码示例
商品分页查询接口
@RestController
@RequestMapping("/api/product")
public class ProductController {
@Autowired
private ProductService productService;
@GetMapping("/list")
public Result<Page<Product>> getProductList(
@RequestParam(required = false) String keyword,
@RequestParam(defaultValue = "1") Integer pageNum,
@RequestParam(defaultValue = "10") Integer pageSize) {
LambdaQueryWrapper<Product> wrapper = new LambdaQueryWrapper<>();
wrapper.like(StringUtils.isNotBlank(keyword), Product::getName, keyword);
return Result.success(productService.page(new Page<>(pageNum, pageSize), wrapper));
}
}
库存扣减SQL
UPDATE product_stock
SET quantity = quantity - #{num}
WHERE product_id = #{pid} AND quantity >= #{num}
系统部署方案
容器化部署
使用Docker Compose编排服务：Nginx作为反向代理，SpringBoot应用打包为Jar镜像，MySQL和Redis使用官方镜像。通过Jenkins实现CI/CD自动化部署。
性能优化
对商品详情页进行静态化处理，采用Nginx缓存热门页面。数据库查询使用索引优化，商品表建立联合索引（category_id, status）。
安全防护
接口防刷采用Guava RateLimiter限流，敏感数据存储进行AES加密。XSS防护通过Jackson的HTML转义实现，SQL注入通过MyBatis预编译防护。
