## Build and Development Commands

### Backend (Java)

**Build the entire backend:**
```bash
cd openhis-server-new
mvn clean package -DskipTests
```

**Run the backend application (development):**
```bash
cd openhis-server-new/openhis-application
mvn spring-boot:run
```

**Alternative: Run directly from IDE:**
- Run the main method in `openhis-server-new/openhis-application/src/main/java/com/openhis/OpenHisApplication.java`

**Start scripts:**
- Linux/Mac: `openhis-server-new/start.sh`
- Windows: `openhis-server-new/start.bat`

### Frontend (Vue 3)

**Install dependencies:**
```bash
cd openhis-ui-vue3
npm install
```

**Development server (with hot reload):**
```bash
npm run dev
```
- Runs on port 81 by default
- Proxies `/dev-api` requests to `http://localhost:18080/openhis`

**Build for production:**
```bash
npm run build:prod    # Production build
npm run build:stage   # Staging build
npm run build:test    # Test environment build
npm run build:dev     # Development build
npm run build:spug    # Spug environment build
```

**Preview production build:**
```bash
npm run preview
```

## Architecture Overview

### Backend Architecture

The backend uses a multi-module Maven architecture with clear separation of concerns:

1. **openhis-application**: Entry point with `OpenHisApplication.java` (d:\his\openhis-server-new\openhis-application\src\main\java\com\openhis\OpenHisApplication.java:20)
   - Scans `com.core` and `com.openhis` packages
   - Configures async processing and YAML service configuration
   - Runs on port 18080 with context path `/openhis`

2. **openhis-domain**: Business domain modules organized by medical functionality:
   - `administration`: Administrative functions
   - `appointmentmanage`: Appointment management
   - `check`: Medical examination/checkup
   - `clinical`: Clinical workflows
   - `crosssystem`: Cross-system integration
   - `document`: Document management
   - `financial`: Financial/billing
   - `lab`: Laboratory operations
   - `medication`: Medication management
   - `triageandqueuemanage`: Patient triage and queue management
   - `yb`, `ybcatalog`, `ybelep`: Insurance (Yi Bao) integration
   - `workflow`: Workflow management
   - `jlau`, `nenu`: Additional domain modules
   - `template`: Template management

3. **Core Modules** (com.core package):
   - `core-system`: User, role, menu, and permission management
   - `core-framework`: Security, exception handling, and framework configurations
   - `core-common`: Shared utilities and base classes
   - `core-quartz`: Scheduled task management
   - `core-generator`: Code generation tools
   - `core-flowable`: Workflow engine integration
   - `core-admin`: Administrative functions

4. **openhis-common**: Domain-specific shared code and utilities under `com.openhis.common` package

**Key Technologies:**
- MyBatis-Plus 3.5.5 for ORM with enhanced CRUD operations
- Druid 1.2.27 connection pool with monitoring at `/druid/*`
- Flowable 6.8.0 for workflow management
- LiteFlow 2.12.4.1 for business rule orchestration
- Swagger 3.0.0 for API documentation
- JWT 0.9.1 for authentication
- Hutool 5.3.8 utility library
- Fastjson2 2.0.58 for JSON processing
- Pinyin4j 2.5.1 for Chinese character to Pinyin conversion

### Frontend Architecture

The frontend uses Vue 3 with composition API and modern tooling:

**Key Files:**
- Entry point: `openhis-ui-vue3/src/main.js`
- Router configuration: `openhis-ui-vue3/src/router/index.js`
- Store initialization: `openhis-ui-vue3/src/store/store.js`
- Vite configuration: `openhis-ui-vue3/vite.config.js`

**State Management:**
- Pinia for global state (replaces Vuex)
- Store modules: `app`, `dict`, `permission`, `settings`, `tagsView`, `user`
- Modules located in `openhis-ui-vue3/src/store/modules/`

**Routing:**
- Vue Router 4.3.0
- Two types of routes:
  - `constantRoutes`: Public routes (login, 404, etc.)
  - `dynamicRoutes`: Permission-based routes loaded dynamically
- Route meta fields: `title`, `icon`, `permissions`, `noCache`, `activeMenu`

**API Integration:**
- Axios 0.27.2 for HTTP requests
- Base API URL configured via environment variables (`VITE_APP_BASE_API`)
- Proxy configuration in vite.config.js for development
  - `/dev-api` → `http://localhost:18080/openhis`
  - `/ybplugin` → `http://localhost:5000` (insurance plugin)
- Request/response interceptors in `openhis-ui-vue3/src/utils/request.js`
- API service files organized by module in `openhis-ui-vue3/src/api/`
  - `administration`, `appoinmentmanage`, `monitor`, `system`, `tool`
  - Shared APIs: `home.js`, `login.js`, `menu.js`, `public.js`

**Component Architecture:**
- Element Plus as the UI framework
- Custom components in `openhis-ui-vue3/src/components/`
- Global components registered in main.js:
  - Pagination, TreeSelect, FileUpload, ImageUpload, ImagePreview
  - RightToolbar, Editor, DictTag

- Type: PostgreSQL
- URL: `jdbc:postgresql://47.116.196.11:15432/postgresql?currentSchema=hisdev`
- Driver: `org.postgresql.Driver`
- Schema: `hisdev`

## Common Development Tasks

### Running Full Stack Locally

**Terminal 1 - Start backend:**
```bash
cd openhis-server-new/openhis-application
mvn spring-boot:run
```

**Terminal 2 - Start frontend:**
```bash
cd openhis-ui-vue3
npm run dev
```

Access the application at:
- Frontend: http://localhost:81
- Backend API: http://localhost:18080/openhis
- Swagger UI: http://localhost:18080/openhis/swagger-ui/index.html
- Druid monitoring: http://localhost:18080/openhis/druid/login.html

### Adding a New Backend Feature

1. Create domain entity in appropriate module under `openhis-domain/[module]/domain/`
2. Create mapper interface in `openhis-domain/[module]/mapper/`
3. Create mapper XML in `openhis-domain/[module]/resources/mapper/` (if custom SQL needed)
4. Create service interface and implementation in `openhis-domain/[module]/service/`
5. Create controller in `openhis-application/src/main/java/com/openhis/web/[module]/`
6. Add MyBatis-Plus annotations if using enhanced features
7. Test endpoints via Swagger UI at `http://localhost:18080/openhis/swagger-ui/index.html`

**Note:** Controllers are organized under `com.openhis.web` by business module (e.g., `web.administration`, `web.clinicalmanage`, `web.patientmanage`, etc.)

### Adding a New Frontend Page

1. Create Vue component in `openhis-ui-vue3/src/views/[module]/`
2. Add API service methods in `openhis-ui-vue3/src/api/`
3. Add route to `openhis-ui-vue3/src/router/index.js` (constantRoutes or dynamicRoutes)
4. Add Pinia store module if state management needed
5. Register global components if reusable

### Testing

**Backend:**
```bash
cd openhis-server-new
mvn test
```

**Frontend:**
- Run unit tests (if configured):
```bash
cd openhis-ui-vue3
npm test
```

## Key Patterns and Conventions

### Backend

- Package structure follows domain-driven design
- Service layer uses `@Service` annotation
- Controllers use `@RestController` with request mapping
- MyBatis-Plus base mapper: `BaseMapper<T>`
- Logical delete field: `validFlag` (1 = active, 0 = deleted)
- Use `@EnableAsync` for async processing
- JWT token stored in `Authorization` header

### Frontend

- Use Vue 3 Composition API (`<script setup>`)
- Element Plus components with Chinese locale (zhCn)
- API calls through centralized request utility in `src/utils/request.js`
- Route-based permission control
- Dictionary data through `useDict()` composable
- Global properties: `$download`, `$downloadGet`, `$parseTime`, `$resetForm`, `$handleTree`, `$formatDateStr`
- CSS in SCSS with global styles in `src/assets/styles/index.scss`
- Registered global components: DictTag, Pagination, TreeSelect, FileUpload, ImageUpload, ImagePreview, RightToolbar, Editor
- Hiprint plugin for printing functionality (window.hiprint)
