+# 应用启动与测试连接指南
+
+本文档提供了多种启动Spring Boot应用程序的方法，以及如何测试API连接。
+
+## 前提条件
+
+在启动应用之前，请确保：
+
+1. 已完成数据库创建（参考 `database_setup_guide.md`）
+2. `application.properties` 中的数据库配置正确
+3. JDK已正确安装（已验证系统有Java 17）
+
+## 方法一：使用IDE启动（推荐）
+
+如果您使用IntelliJ IDEA或Eclipse等IDE：
+
+1. 打开IDE，导入`backend`目录作为Maven项目
+2. 等待IDE下载依赖并构建项目
+3. 找到主类 `SecondHandMarketApplication.java`
+4. 右键点击该类，选择"Run"或"Debug"选项
+5. 观察控制台输出，确认应用是否成功启动
+
+## 方法二：使用内置Maven包装器
+
+如果系统中没有安装Maven，但项目中有Maven包装器：
+
+1. 检查`backend`目录下是否有`mvnw`（Windows下为`mvnw.cmd`）文件
+2. 如果没有，我们需要先创建Maven包装器
+
+### 创建Maven包装器（如果不存在）
+
+打开命令提示符（CMD）或PowerShell，进入`backend`目录：
+
+```bash
+cd C:\Users\asus\AndroidStudioProjects\Project\LLRiseTabBarDemo\backend
+```
+
+然后执行以下命令创建Maven包装器：
+
+```bash
+java -cp .\pom.xml org.apache.maven.wrapper.MavenWrapperMain --version
+```
+
+注意：如果上述命令失败，您可以手动下载Maven包装器文件。
+
+### 使用Maven包装器启动应用
+
+```bash
+# Windows命令
+mvnw.cmd spring-boot:run
+
+# 或者使用PowerShell
+./mvnw spring-boot:run
+```
+
+## 方法三：使用Java直接运行
+
+如果您能获取到编译好的JAR文件：
+
+1. 首先构建项目（如果有Maven）：
+   ```bash
+   mvn clean package
+   ```
+
+2. 然后运行生成的JAR文件：
+   ```bash
+   java -jar target\secondhandmarket-0.0.1-SNAPSHOT.jar
+   ```
+
+## 方法四：使用Spring Boot Dashboard（IntelliJ IDEA）
+
+如果您使用IntelliJ IDEA Ultimate版本：
+
+1. 打开IDE，导入项目
+2. 找到底部的"Spring Boot Dashboard"选项卡
+3. 在仪表板中找到您的应用
+4. 点击绿色运行按钮启动应用
+
+## 验证应用是否成功启动
+
+应用成功启动后，您会在控制台看到类似以下输出：
+
+```
+2024-xx-xx xx:xx:xx.xxx  INFO xxx --- [           main] o.s.b.w.embedded.tomcat.TomcatWebServer  : Tomcat started on port(s): 8080 (http)
+2024-xx-xx xx:xx:xx.xxx  INFO xxx --- [           main] c.e.secondhandmarket.SecondHandMarketApplication : Started SecondHandMarketApplication in x.xxx seconds
+```
+
+这表示应用已成功启动，并在8080端口监听HTTP请求。
+
+## 测试API连接
+
+### 使用浏览器测试
+
+打开浏览器，访问以下URL测试基本连接：
+
+```
+http://localhost:8080/users/exists/phone/13800138000
+```
+
+您应该会看到类似以下JSON响应：
+
+```json
+{"exists":false}
+```
+
+### 使用Postman测试（推荐）
+
+1. 下载并安装Postman（https://www.postman.com/downloads/）
+2. 打开Postman，创建一个新的请求
+
+#### 测试用户注册
+
+- 请求类型：POST
+- URL：http://localhost:8080/users/register
+- 请求体（Body）：选择raw和JSON格式
+```json
+{
+  "phone": "13800138000",
+  "password": "123456",
+  "nickname": "测试用户"
+}
+```
+- 点击Send按钮
+
+#### 测试用户登录
+
+- 请求类型：POST
+- URL：http://localhost:8080/users/login
+- 请求体（Body）：
+```json
+{
+  "phone": "13800138000",
+  "password": "123456"
+}
+```
+- 点击Send按钮
+
+#### 测试商品列表获取
+
+- 请求类型：GET
+- URL：http://localhost:8080/items
+- 点击Send按钮
+
+### 使用curl命令测试（Windows 10/11）
+
+如果您的Windows系统已安装curl（Windows 10/11通常预装），可以使用以下命令测试：
+
+```bash
+# 测试手机号是否存在
+curl http://localhost:8080/users/exists/phone/13800138000
+
+# 测试用户注册
+curl -X POST -H "Content-Type: application/json" -d "{\"phone\":\"13800138000\",\"password\":\"123456\",\"nickname\":\"测试用户\"}" http://localhost:8080/users/register
+```
+
+## 常见启动问题及解决方案
+
+### 1. 数据库连接失败
+
+错误信息可能包含：`Failed to obtain JDBC Connection`
+
+**解决方案：**
+- 确认MySQL服务是否正在运行
+- 检查`application.properties`中的数据库配置是否正确
+- 确保数据库`secondhandmarket`已创建
+- 验证用户名和密码是否正确
+
+### 2. 端口被占用
+
+错误信息可能包含：`Address already in use`
+
+**解决方案：**
+- 修改`application.properties`中的端口号：
+  ```properties
+  server.port=8081
+  ```
+- 或者关闭占用8080端口的其他应用
+
+### 3. 依赖下载失败
+
+错误信息可能包含：`Could not resolve dependencies`
+
+**解决方案：**
+- 确保网络连接正常
+- 可以尝试使用国内Maven镜像（修改pom.xml）
+
+### 4. 类找不到错误
+
+错误信息可能包含：`ClassNotFoundException`
+
+**解决方案：**
+- 重新构建项目
+- 确保所有依赖都已正确下载
+
+## 应用停止方法
+
+1. 在IDE中，点击停止按钮
+2. 在命令行中，按Ctrl + C组合键
+3. 在Windows任务管理器中结束Java进程
+
+## 开发环境提示
+
+1. 在开发环境中，可以在`application.properties`中添加以下配置以获得更好的调试体验：
+   ```properties
+   # 启用热重载
+   spring.devtools.restart.enabled=true
+   # 设置日志级别
+   logging.level.root=INFO
+   logging.level.com.example.secondhandmarket=DEBUG
+   ```
+
+2. 如果您需要频繁修改代码并测试，建议使用IDE的Debug模式启动应用，这样可以：
+   - 设置断点
+   - 单步执行代码
+   - 查看变量值
+
+祝您测试顺利！

+# 数据库创建详细操作步骤
+
+## 1. MySQL数据库安装
+
+如果还没有安装MySQL，请按照以下步骤安装：
+
+### Windows系统安装MySQL
+
+1. 访问MySQL官方网站下载页面：[MySQL Community Server](https://dev.mysql.com/downloads/mysql/)
+2. 选择Windows版本下载安装包（推荐使用MySQL Installer）
+3. 运行安装程序，选择"Developer Default"或"Server only"安装类型
+4. 按照安装向导提示完成安装，设置root用户密码（请记住这个密码）
+5. 确保MySQL服务设置为自动启动
+
+### 验证MySQL安装
+
+打开命令提示符（CMD）或PowerShell，输入以下命令验证MySQL是否正确安装：
+
+```bash
+mysql --version
+```
+
+如果安装成功，会显示MySQL的版本信息。
+
+## 2. 启动MySQL服务
+
+### Windows系统
+
+1. 按下Win + R，输入`services.msc`打开服务管理器
+2. 找到"MySQL80"服务（或类似名称）
+3. 确保服务状态为"正在运行"，如果未运行，右键点击选择"启动"
+
+## 3. 连接到MySQL服务器
+
+### 使用命令行连接
+
+打开命令提示符（CMD）或PowerShell，输入以下命令连接到MySQL：
+
+```bash
+mysql -u root -p
+```
+
+系统会提示输入密码，输入您在安装MySQL时设置的root密码。
+
+### 使用MySQL Workbench连接（可选）
+
+如果您安装了MySQL Workbench，可以通过图形界面连接：
+1. 打开MySQL Workbench
+2. 点击左侧的"Local instance MySQL80"连接
+3. 输入密码并连接
+
+## 4. 创建数据库
+
+连接成功后，执行以下SQL命令创建数据库：
+
+```sql
+CREATE DATABASE secondhandmarket CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
+```
+
+执行成功后，您会看到类似以下输出：
+```
+Query OK, 1 row affected (0.02 sec)
+```
+
+## 5. 选择数据库
+
+执行以下命令选择刚创建的数据库：
+
+```sql
+USE secondhandmarket;
+```
+
+输出：
+```
+Database changed
+```
+
+## 6. 创建表结构
+
+执行以下SQL语句创建所需的表结构：
+
+### 创建users表
+
+```sql
+CREATE TABLE users (
+    id BIGINT AUTO_INCREMENT PRIMARY KEY,
+    phone VARCHAR(20) NOT NULL UNIQUE,
+    password VARCHAR(100) NOT NULL,
+    nickname VARCHAR(50),
+    avatar VARCHAR(255),
+    gender VARCHAR(10),
+    bio VARCHAR(255),
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    last_login TIMESTAMP,
+    status VARCHAR(20) DEFAULT 'ACTIVE'
+);
+```
+
+### 创建items表
+
+```sql
+CREATE TABLE items (
+    id BIGINT AUTO_INCREMENT PRIMARY KEY,
+    title VARCHAR(100) NOT NULL,
+    description TEXT,
+    price DECIMAL(10, 2) NOT NULL,
+    category VARCHAR(50) NOT NULL,
+    status VARCHAR(20) DEFAULT 'AVAILABLE',
+    images TEXT,
+    seller_id BIGINT NOT NULL,
+    view_count INT DEFAULT 0,
+    like_count INT DEFAULT 0,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
+    FOREIGN KEY (seller_id) REFERENCES users(id)
+);
+```
+
+### 创建chat_messages表
+
+```sql
+CREATE TABLE chat_messages (
+    id BIGINT AUTO_INCREMENT PRIMARY KEY,
+    sender_id BIGINT NOT NULL,
+    receiver_id BIGINT NOT NULL,
+    item_id BIGINT NOT NULL,
+    content TEXT NOT NULL,
+    is_read BOOLEAN DEFAULT FALSE,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    FOREIGN KEY (sender_id) REFERENCES users(id),
+    FOREIGN KEY (receiver_id) REFERENCES users(id),
+    FOREIGN KEY (item_id) REFERENCES items(id)
+);
+```
+
+## 7. 创建索引（提高查询性能）
+
+为常用查询字段创建索引：
+
+```sql
+-- 为users表的phone字段创建索引
+CREATE INDEX idx_users_phone ON users(phone);
+
+-- 为items表的常用查询字段创建索引
+CREATE INDEX idx_items_seller_id ON items(seller_id);
+CREATE INDEX idx_items_category ON items(category);
+CREATE INDEX idx_items_status ON items(status);
+CREATE INDEX idx_items_price ON items(price);
+
+-- 为chat_messages表的查询字段创建索引
+CREATE INDEX idx_chat_messages_sender_receiver ON chat_messages(sender_id, receiver_id);
+CREATE INDEX idx_chat_messages_receiver_id ON chat_messages(receiver_id);
+CREATE INDEX idx_chat_messages_item_id ON chat_messages(item_id);
+```
+
+## 8. 验证表结构
+
+执行以下命令查看创建的表：
+
+```sql
+SHOW TABLES;
+```
+
+输出应该包括：
+```
++---------------------------+
+| Tables_in_secondhandmarket |
++---------------------------+
+| chat_messages             |
+| items                     |
+| users                     |
++---------------------------+
+```
+
+## 9. 配置应用程序连接
+
+确保`application.properties`文件中的数据库配置正确：
+
+```properties
+spring.datasource.url=jdbc:mysql://localhost:3306/secondhandmarket?useSSL=false&serverTimezone=UTC
+spring.datasource.username=root
+spring.datasource.password=061723  # 这是您设置的MySQL密码
+spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
+
+# JPA配置
+spring.jpa.hibernate.ddl-auto=update
+spring.jpa.show-sql=true
+spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL8Dialect
+```
+
+## 10. 测试连接
+
+当您启动Spring Boot应用程序时，它应该能够成功连接到MySQL数据库。如果连接失败，请检查以下几点：
+
+1. MySQL服务是否正在运行
+2. 数据库名称是否正确
+3. 用户名和密码是否正确
+4. 防火墙是否允许连接
+5. MySQL是否允许root用户从localhost连接
+
+## 11. 注意事项
+
+1. 在生产环境中，不建议使用root用户，应该创建一个具有适当权限的新用户
+2. 确保数据库密码安全，不要硬编码在应用程序中
+3. 定期备份数据库
+4. 考虑使用连接池来优化数据库连接管理
+
+## 故障排除
+
+如果遇到连接问题，请尝试以下命令检查MySQL用户权限：
+
+```sql
+SELECT user, host FROM mysql.user;
+GRANT ALL PRIVILEGES ON secondhandmarket.* TO 'root'@'localhost';
+FLUSH PRIVILEGES;
+```
