## Quick Start

### 1. Prerequisites

- JDK 17+
- Maven 3.6+
- MySQL 8.0+

### 2. Database Setup

```bash
# Create database and import schema
mysql -u root -p < src/main/resources/db/migration/V1__init_schema.sql
```

### 3. Configuration

Edit `src/main/resources/application-dev.yml`:

```yaml
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/reading_platform
    username: your_username
    password: your_password
```

### 4. Build and Run

```bash
# Build
mvn clean package -DskipTests

# Run
java -jar target/reading-platform-1.0.0.jar

# Or run with Maven
mvn spring-boot:run
```

### 5. API Documentation

After starting the application, access the API documentation at:

- Swagger UI: http://localhost:8080/swagger-ui.html
- Knife4j UI: http://localhost:8080/doc.html

## Test Accounts

| Role | Username | Password |
|------|----------|----------|
| Admin | admin | 123456 |

School, teacher, and parent accounts need to be created through the admin interface.

## Database Tables (27)

| Module | Tables |
|--------|--------|
| Tenant | tenants, tenant_courses |
| Users | admin_users, teachers, students, parents, parent_students |
| Class | classes, class_teachers, student_class_history |
| Course | courses, course_versions, course_resources, course_scripts, course_script_pages, course_activities |
| Lesson | lessons, lesson_feedbacks, student_records |
| Task | tasks, task_targets, task_completions, task_templates |
| Growth | growth_records |
| Resource | resource_library, resource_items |
| Schedule | schedule_plans, schedule_templates |
| System | system_settings, notifications, operation_logs, tags |

## Development

### Adding a New Entity

1. Create entity class in `entity/`
2. Create mapper interface in `mapper/`
3. Create service interface in `service/`
4. Create service implementation in `service/impl/`
5. Create controller in appropriate `controller/` subdirectory

### Code Style

- Use Lombok annotations to reduce boilerplate
- Follow Spring Boot conventions
- Use `@RequireRole` annotation for role-based access control
