**Prison Module Structure** (`yudao-module-prison/`):
```
src/main/java/cn/iocoder/yudao/module/prison/

```

**Database Schema Convention**:
- Table prefix: `prison_{module}`
- Common fields: `id`, `creator`, `create_time`, `updater`, `update_time`, `deleted`, `tenant_id`
- Soft delete: `deleted` bit(1) field
- Tenant support: `tenant_id` bigint field

### Frontend Structure
```

├── views/prison/{module}/       # Page components
│   ├── index.vue                # List page with table/search
│   └── {Module}Form.vue         # Create/Edit form dialog
├── api/prison/{module}/         # API definitions

└── config/                      # Configuration files
```

**Frontend API Pattern** (`api/prison/{module}/index.ts`):
```typescript
// Interface definitions
export interface Area {
  id: number;
  name?: string;
  code: string;
  type: number;
  // ...
}

// API object with methods
export const AreaApi = {
  getAreaPage: async (params: any) => { ... },
  getArea: async (id: number) => { ... },
  createArea: async (data: Area) => { ... },
  updateArea: async (data: Area) => { ... },
  deleteArea: async (id: number) => { ... },
  deleteAreaList: async (ids: number[]) => { ... },
  exportArea: async (params) => { ... }
}
```

**Frontend View Pattern** (`views/prison/{module}/index.vue`):
- Uses Element Plus table with pagination
- Search form with filters
- CRUD operations with dialog forms
- Export functionality
- Batch delete support

## Database Configuration

**Development Database**:
```
URL: jdbc:mysql://192.168.10.130:3306/xlcp_dev?useSSL=false&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true&nullCatalogMeansCurrent=true&rewriteBatchedStatements=true
Username: (configured in application-local.yaml)
Password: (configured in application-local.yaml)
```

**SQL Scripts Location**:
- Module tables and permissions: `backend/yudao-module-prison/src/main/resources/sql/prison_module.sql`
- Execute this script to create all prison module tables and menu permissions

## Configuration Files

### Backend Configuration
**Location**: `backend/yudao-server/src/main/resources/`

**Key Files**:
- `application.yaml` - Base configuration
- `application-local.yaml` - Local development (port 48080)
- `application-dev.yaml` - Development environment

**Mock Settings** (application-local.yaml):
```yaml
yudao:
  mock:
    enable: true
    secret: emsoft
```

### Frontend Configuration
**Location**: `frontend/`

**Key Files**:
- `.env.local` - Local development environment
- `.env.dev` - Development environment
- `.env.test` - Testing environment
- `.env.prod` - Production environment

**Local Environment** (.env.local):
```
VITE_BASE_URL='http://localhost:48080'
VITE_API_URL='/admin-api'
VITE_DEV=true
```

## Development Workflow

### Adding a New Module
1. **Backend**:
   - Create package: `controller/admin/{module}/`, `service/{module}/`, `dal/dataobject/{module}/`, etc.
   - Define DO in `dal/dataobject/{module}/{Module}DO.java`
   - Create Mapper in `dal/mysql/{module}/{Module}Mapper.java`
   - Implement Service in `service/{module}/impl/{Module}ServiceImpl.java`
   - Create Controller in `controller/admin/{module}/{Module}Controller.java`
   - Define VOs in `controller/admin/{module}/vo/`
   - Add MapStruct converter in `convert/{module}/{Module}Convert.java`
   - Add enum if needed in `enums/`

2. **Frontend**:
   - Create API: `api/prison/{module}/index.ts`
   - Create views: `views/prison/{module}/index.vue` and `{Module}Form.vue`
   - Define TypeScript interfaces
   - Implement CRUD operations

3. **Database**:
   - Add table creation SQL to `backend/yudao-module-prison/src/main/resources/sql/prison_module.sql`
   - Add menu permission SQL

### Testing a Module
**Backend**:
```bash
# Test all prison module
cd backend/yudao-module-prison && mvn test

# Test specific class
mvn test -Dtest=PrisonAreaControllerTest
```

**Frontend**:
```bash
# Type check only
cd frontend && pnpm ts:check

# Dev server with hot reload
pnpm dev
```

## Common Patterns

### Backend Controller Pattern
```java
@RestController
@RequestMapping("/prison/{module}")
@Tag(name = "管理后台 - {中文名称}")
public class {Module}Controller {

    @Resource
    private {Module}Service {module}Service;

    @PostMapping("/create")
    @Operation(summary = "创建{中文名称}")
    @PreAuthorize("@ss.hasPermission('prison:{module}:create')")
    public CommonResult<Long> create(@Valid @RequestBody {Module}SaveReqVO vo) {
        return success({module}Service.create(vo));
    }

    @PutMapping("/update")
    @Operation(summary = "更新{中文名称}")
    @PreAuthorize("@ss.hasPermission('prison:{module}:update')")
    public CommonResult<Boolean> update(@Valid @RequestBody {Module}SaveReqVO vo) {
        return success({module}Service.update(vo));
    }

    @DeleteMapping("/delete")
    @Operation(summary = "删除{中文名称}")
    @PreAuthorize("@ss.hasPermission('prison:{module}:delete')")
    public CommonResult<Boolean> delete(@RequestParam("id") Long id) {
        return success({module}Service.delete(id));
    }

    @GetMapping("/page")
    @Operation(summary = "分页查询{中文名称}")
    @PreAuthorize("@ss.hasPermission('prison:{module}:query')")
    public CommonResult<PageResult<{Module}RespVO>> page(@Valid {Module}PageReqVO vo) {
        return success({module}Service.page(vo));
    }

    @GetMapping("/get")
    @Operation(summary = "查询{中文名称}详情")
    @PreAuthorize("@ss.hasPermission('prison:{module}:query')")
    public CommonResult<{Module}RespVO> get(@RequestParam("id") Long id) {
        return success({module}Service.get(id));
    }

    @GetMapping("/export-excel")
    @Operation(summary = "导出{中文名称} Excel")
    @PreAuthorize("@ss.hasPermission('prison:{module}:export')")
    public void exportExcel(@Valid {Module}PageReqVO vo, HttpServletResponse response) {
        {module}Service.exportExcel(vo, response);
    }
}
```

### Service Layer Pattern
```java
public interface {Module}Service {
    Long create({Module}SaveReqVO vo);
    Boolean update({Module}SaveReqVO vo);
    Boolean delete(Long id);
    {Module}RespVO get(Long id);
    PageResult<{Module}RespVO> page({Module}PageReqVO vo);
    void exportExcel({Module}PageReqVO vo, HttpServletResponse response);
}
```

### Frontend API Pattern
```typescript
export interface {Module} {
  id: number;
  // ... other fields
}

export const {Module}Api = {
  getPage: async (params: any) => {
    return await request.get({ url: `/{module}/page`, params })
  },
  get: async (id: number) => {
    return await request.get({ url: `/{module}/get?id=${id}` })
  },
  create: async (data: {Module}) => {
    return await request.post({ url: `/{module}/create`, data })
  },
  update: async (data: {Module}) => {
    return await request.put({ url: `/{module}/update`, data })
  },
  delete: async (id: number) => {
    return await request.delete({ url: `/{module}/delete?id=${id}` })
  },
  deleteList: async (ids: number[]) => {
    return await request.delete({ url: `/{module}/delete-list?ids=${ids.join(',')}` })
  },
  export: async (params) => {
    return await request.download({ url: `/{module}/export-excel`, params })
  }
}
```

## Important Notes

- **Package Prefix**: All prison module classes use `cn.iocoder.yudao.module.prison`
- **API Base Path**: `/admin-api/prison/{module}`
- **Permission Codes**: Follow pattern `prison:{module}:{action}` (e.g., `prison:area:create`)
- **Frontend Paths**: Use `views/prison/` and `api/prison/` directories
- **Database Tables**: Use `prison_` prefix and soft delete (`deleted` field)
- **Error Codes**: Defined in `ErrorCodeConstants.java` (shared across modules)
- **Enum Types**: Defined in `enums/` directory with `Enum` suffix
- **VO Naming**: `SaveReqVO`, `PageReqVO`, `RespVO` suffixes
- **DO Naming**: `{Module}DO` with table mapping via `@TableName`
- **Mapper Naming**: `{Module}Mapper` extending `BaseMapper<{Module}DO>`
- **Service Impl**: Located in `service/{module}/impl/` directory

## Code Generation

**Source**: `codegen/` directory contains template files for generating new modules
**Usage**: Copy and adapt these templates when adding new prison modules

## Build & Deployment

**Backend JAR**: `backend/yudao-server/target/yudao-server-{version}.jar`
**Frontend Dist**: `frontend/dist/` (static files for nginx)

## Troubleshooting

**Common Issues**:
1. **Maven dependency issues**: Run `mvn clean install -U` to force update
2. **Frontend type errors**: Run `pnpm ts:check` to identify issues
3. **Database connection**: Verify MySQL is running and credentials in `application-local.yaml`
4. **Mock mode**: Check `yudao.mock.enable` setting in configuration
5. **Port conflicts**: Default backend port is 48080

**Debug Mode**:
- Backend: Add `--debug` to mvn command for remote debugging on port 5005
- Frontend: Browser dev tools + Vue DevTools browser extension
