+# 订单管理系统（Kafka）
+
+该项目是一个基于Kafka的订单管理服务，包含以下核心组件：
+
+- `main.go` - 服务入口文件
+- `go.mod` - Go语言依赖管理文件
+- `config.toml` - 配置文件（环境变量/数据库设置等）
+- `docker-compose.yml` - 容器化部署配置
+- `.dockerignore` - Docker构建忽略规则
+
+## 快速开始
+
+1. 安装依赖
+```bash
+go mod download
+```
+
+2. 启动Kafka环境
+```bash
+docker-compose up -d
+```
+
+3. 运行服务
+```bash
+go run main.go
+```
+
+## 系统要求
+
+- Go 1.21+
+- Docker 20.10+
+- Kafka 2.0+
+
+环境变量可通过`.env`文件配置
+## 配置文件说明
+
+配置文件采用TOML格式，包含以下主要配置块：
+
+### Kafka配置
+```toml
+[kafka]
+brokers = ["niit-node3:9092"]  # Kafka代理地址列表
+topic = "orders"               # 消息主题名称
+send_interval = "1s"           # 消息发送时间间隔
+retry_max = 3                  # 最大重试次数
+retry_backoff_ms = 100         # 重试间隔时间（毫秒）
+version = "2.8.0"              # Kafka版本号
+```
+
+### 订单数据配置
+```toml
+[order]
+categories = [                # 商品分类配置
+  { name = "电子", items = ["手机", "笔记本电脑", "耳机", "平板", "相机"] },
+  { name = "服饰", items = ["T恤", "牛仔裤", "运动鞋", "外套", "连衣裙"] },
+  { name = "食品", items = ["饼干", "巧克力", "牛奶", "方便面", "坚果"] },
+  { name = "家居", items = ["沙发", "床垫", "餐桌", "椅子", "台灯"] },
+  { name = "图书", items = ["小说", "漫画", "教材", "杂志", "工具书"] }
+]
+scores = [80, 90, 100]        # 订单评分范围
+valids = ["true", "false"]     # 订单有效性状态
+```
