+# NiuMall 后端服务 (Java 版本)
+
+活牛采购智能数字化系统 - 后端服务
+
+## 项目介绍
+
+本项目是将原有的 Node.js 后端服务重构为基于 Java 的微服务架构，使用 Spring Boot 和 Spring Cloud 构建。
+
+## 技术栈
+
+- Java 17
+- Spring Boot 3.1.0
+- Spring Cloud 2022.0.3
+- Spring Data JPA
+- MySQL 8.0
+- Maven 3.8+
+
+## 服务架构
+
+- **user-service**: 用户服务
+- **auth-service**: 认证服务
+- **order-service**: 订单服务
+- **supplier-service**: 供应商服务
+- **transport-service**: 运输服务
+- **finance-service**: 财务服务
+- **quality-service**: 质检服务
+
+## 项目结构
+
+```
+backend-java/
+├── auth-service/          # 认证服务
+├── user-service/          # 用户服务
+├── order-service/         # 订单服务
+├── supplier-service/      # 供应商服务
+├── transport-service/     # 运输服务
+├── finance-service/       # 财务服务
+├── quality-service/       # 质检服务
+├── common/                # 公共模块
+└── docs/                  # 文档
+```
+
+## 构建和运行
+
+### 环境要求
+
+- JDK 17+
+- Maven 3.8+
+- MySQL 8.0+
+
+### 构建项目
+
+```bash
+# 进入项目根目录
+cd backend-java
+
+# 编译项目
+mvn clean compile
+
+# 打包项目
+mvn clean package
+```
+
+### 运行服务
+
+```bash
+# 运行用户服务
+cd user-service
+mvn spring-boot:run
+```
+
+## 数据库配置
+
+项目使用 MySQL 数据库，连接配置在各个服务的 `application.yml` 文件中。
+
+## API 文档
+
+API 文档使用 Swagger 生成，启动服务后访问 `http://localhost:8080/swagger-ui.html` 查看。
+
+## 部署
+
+推荐使用 Docker 进行部署，每个服务都可以独立打包成 Docker 镜像。

+# Java 后端服务运行说明
+
+## 环境要求
+
+1. JDK 17 或更高版本
+2. Maven 3.8 或更高版本
+
+## 安装 Maven（如果尚未安装）
+
+### macOS
+
+如果已安装 Homebrew：
+```bash
+brew install maven
+```
+
+如果没有安装 Homebrew，先安装 Homebrew：
+```bash
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+```
+然后安装 Maven：
+```bash
+brew install maven
+```
+
+### Windows
+
+1. 访问 [Maven 官网](https://maven.apache.org/download.cgi)
+2. 下载最新版本的 Maven
+3. 解压到指定目录
+4. 配置环境变量：
+   - 添加 MAVEN_HOME 环境变量，指向 Maven 安装目录
+   - 将 %MAVEN_HOME%\bin 添加到 PATH 环境变量
+
+### Linux (Ubuntu/Debian)
+
+```bash
+sudo apt update
+sudo apt install maven
+```
+
+## 构建和运行服务
+
+### 1. 使用 Maven Wrapper（推荐）
+
+首先初始化 Maven Wrapper：
+```bash
+cd backend-java
+mvn -N io.takari:maven:wrapper
+```
+
+然后构建项目：
+```bash
+cd user-service
+./mvnw clean compile
+```
+
+### 2. 直接使用 Maven
+
+如果已安装 Maven：
+```bash
+cd backend-java/user-service
+mvn clean compile
+mvn spring-boot:run
+```
+
+### 3. 打包并运行
+
+```bash
+cd backend-java/user-service
+mvn clean package
+java -jar target/*.jar
+```
+
+## 服务访问
+
+用户服务默认运行在 8081 端口：
+- 健康检查: http://localhost:8081/actuator/health
+- 用户 API: http://localhost:8081/api/users
+
+## 数据库配置
+
+服务会自动连接到配置文件中指定的 MySQL 数据库：
+- 主机: 129.211.213.226
+- 端口: 9527
+- 数据库: jiebandata
+- 用户名: root
+- 密码: aiotAiot123!
+
+确保网络可以访问该数据库服务器。
+
+## 常见问题
+
+1. **端口被占用**: 修改 `application.yml` 中的 `server.port` 配置
+2. **数据库连接失败**: 检查网络连接和数据库配置
+3. **依赖下载失败**: 配置 Maven 镜像源或检查网络连接
+
+## 开发工具
+
+推荐使用以下 IDE 进行开发：
+- IntelliJ IDEA
+- Eclipse with Spring Tools
+- VS Code with Java extensions
