}
}
}核心架构实现
1. 领域驱动设计(DDD)实践
<?php
// domain/user/UserDomainService.php
namespace domainuser;
use appcommonmodelUser as UserModel;
use domainuserentityUserEntity;
use domainuserrepositoryUserRepository;
use domainusereventUserRegisteredEvent;
class UserDomainService
{
protected $userRepository;
protected $event;
public function __construct(UserRepository $userRepository)
{
$this->userRepository = $userRepository;
}
/**
* 用户注册领域服务
*/
public function registerUser(array $userData): UserEntity
{
// 验证业务规则
$this->validateRegistration($userData);
// 创建用户实体
$userEntity = new UserEntity($userData);
$userEntity->setPassword($this->hashPassword($userData['password']));
$userEntity->setRegisterIp(request()->ip());
$userEntity->setStatus(UserEntity::STATUS_ACTIVE);
// 保存到仓储
$savedUser = $this->userRepository->save($userEntity);
// 发布领域事件
event(new UserRegisteredEvent($savedUser));
return $savedUser;
}
/**
* 复杂业务逻辑：用户升级VIP
*/
public function upgradeToVip(int $userId, string $vipType): bool
{
$user = $this->userRepository->findById($userId);
if (!$user) {
throw new Exception('用户不存在');
}
if ($user->isVip()) {
throw new Exception('用户已是VIP');
}
// 执行升级逻辑
$user->setVipType($vipType);
$user->setVipExpireAt(strtotime('+1 year'));
return $this->userRepository->save($user);
}
private function validateRegistration(array $userData): void
{
// 复杂的业务规则验证
if ($this->userRepository->existsByEmail($userData['email'])) {
throw new Exception('邮箱已被注册');
}
if ($this->userRepository->existsByMobile($userData['mobile'])) {
throw new Exception('手机号已被注册');
}
// 更多业务规则...
}
private function hashPassword(string $password): string
{
return password_hash($password, PASSWORD_DEFAULT);
}
}2. 仓储模式与数据访问层
<?php
// domain/user/repository/UserRepository.php
namespace domainuserrepository;
use domainuserentityUserEntity;
use thinkfacadeDb;
interface UserRepository
{
public function findById(int $id): ?UserEntity;
public function save(UserEntity $user): UserEntity;
public function existsByEmail(string $email): bool;
public function existsByMobile(string $mobile): bool;
public function findByCondition(array $condition): array;
}
// domain/user/repository/EloquentUserRepository.php
class EloquentUserRepository implements UserRepository
{
public function findById(int $id): ?UserEntity
{
$user = Db::name('user')
->where('id', $id)
->find();
return $user ? UserEntity::fromArray($user) : null;
}
public function save(UserEntity $user): UserEntity
{
$data = $user->toArray();
if ($user->getId()) {
// 更新
Db::name('user')
->where('id', $user->getId())
->update($data);
} else {
// 新增
$userId = Db::name('user')->insertGetId($data);
$user->setId($userId);
}
return $user;
}
public function existsByEmail(string $email): bool
{
return Db::name('user')
->where('email', $email)
->count() > 0;
}
public function findByCondition(array $condition): array
{
$query = Db::name('user');
foreach ($condition as $field => $value) {
if (is_array($value)) {
$query->whereIn($field, $value);
} else {
$query->where($field, $value);
}
}
$users = $query->select();
return array_map([UserEntity::class, 'fromArray'], $users);
}
}多应用模式深度配置
1. 应用独立配置管理
<?php
// config/admin/app.php
return [
// 后台应用配置
'app_debug' => false,
'default_app' => 'admin',
'auto_multi_app' => true,
// 路由配置
'route_config_file' => ['route'],
'url_route_on' => true,
// 中间件配置
'default_middleware' => [
'admin\middleware\AuthCheck',
'admin\middleware\PermissionCheck',
'admin\middleware\OperationLog',
],
];
// config/api/app.php
return [
// API应用配置
'app_debug' => env('APP_DEBUG', false),
'default_app' => 'api',
// API特殊配置
'default_return_type' => 'json',
'route_complete_match' => true,
// 中间件配置
'default_middleware' => [
'api\middleware\ApiAuth',
'api\middleware\RateLimit',
'api\middleware\Cors',
],
];2. 自定义中间件开发
<?php
// app/api/middleware/ApiVersion.php
namespace appapimiddleware;
use thinkRequest;
use thinkResponse;
class ApiVersion
{
public function handle(Request $request, Closure $next)
{
// 从请求头获取API版本
$version = $request->header('Api-Version', 'v1');
// 验证版本号格式
if (!preg_match('/^vd+$/', $version)) {
return json([
'code' => 400,
'message' => 'Invalid API version format',
'data' => null
]);
}
// 设置当前版本到请求对象
$request->apiVersion = $version;
// 动态加载对应版本的路由
$this->loadVersionRoutes($version);
return $next($request);
}
private function loadVersionRoutes(string $version): void
{
$routeFile = app()->getBasePath() . "api/{$version}/route.php";
if (file_exists($routeFile)) {
include $routeFile;
}
}
}
// app/api/middleware/RateLimit.php
class RateLimit
{
protected $redis;
protected $config = [
'max_requests' => 100, // 最大请求数
'time_window' => 60, // 时间窗口(秒)
'ban_time' => 300, // 封禁时间(秒)
];
public function handle(Request $request, Closure $next)
{
$clientIp = $request->ip();
$key = "rate_limit:{$clientIp}";
// 检查是否被封禁
if ($this->isBanned($key)) {
return $this->tooManyRequestsResponse();
}
// 检查请求频率
if (!$this->checkRate($key)) {
$this->banClient($key);
return $this->tooManyRequestsResponse();
}
return $next($request);
}
private function checkRate(string $key): bool
{
$current = $this->redis->lLen($key);
if ($current >= $this->config['max_requests']) {
return false;
}
$this->redis->lPush($key, time());
$this->redis->expire($key, $this->config['time_window']);
return true;
}
private function isBanned(string $key): bool
{
return $this->redis->exists("{$key}:banned");
}
private function banClient(string $key): void
{
$this->redis->setex("{$key}:banned", $this->config['ban_time'], 1);
}
private function tooManyRequestsResponse(): Response
{
return json([
'code' => 429,
'message' => 'Too many requests',
'data' => null
], 429);
}
}高级特性与性能优化
1. 服务容器与依赖注入
<?php
// common/lib/ServiceContainer.php
namespace commonlib;
use thinkContainer;
class ServiceContainer
{
protected static $instance;
protected $container;
public static function getInstance()
{
if (is_null(self::$instance)) {
self::$instance = new self();
}
return self::$instance;
}
public function __construct()
{
$this->container = Container::getInstance();
$this->registerServices();
}
private function registerServices(): void
{
// 注册领域服务
$this->container->bind('userDomainService', function() {
$repository = new domainuserrepositoryEloquentUserRepository();
return new domainuserUserDomainService($repository);
});
// 注册缓存服务
$this->container->bind('cacheService', function() {
return new commonserviceRedisCacheService();
});
// 注册邮件服务
$this->container->bind('emailService', function() {
return new commonserviceEmailService();
});
}
public function make(string $abstract, array $vars = [])
{
return $this->container->make($abstract, $vars);
}
}
// 在控制器中使用依赖注入
namespace appapicontroller;
use domainuserUserDomainService;
class UserController
{
protected $userDomainService;
public function __construct(UserDomainService $userDomainService)
{
$this->userDomainService = $userDomainService;
}
public function register()
{
$userData = request()->post();
try {
$user = $this->userDomainService->registerUser($userData);
return json([
'code' => 200,
'message' => '注册成功',
'data' => $user->toArray()
]);
} catch (Exception $e) {
return json([
'code' => 400,
'message' => $e->getMessage(),
'data' => null
]);
}
}
}2. 数据库优化与查询构建
<?php
// common/trait/ModelQueryTrait.php
namespace commontrait;
trait ModelQueryTrait
{
/**
* 分页查询优化
*/
public function scopePaginateOptimized($query, $page = 1, $size = 15)
{
// 使用游标分页提升性能
return $query->page($page, $size)
->cache("paginate:{$page}:{$size}", 60)
->select();
}
/**
* 关联查询优化
*/
public function scopeWithOptimized($query, $relations = [])
{
foreach ($relations as $relation) {
$query->with([
$relation => function($query) {
// 只选择需要的字段
$query->field('id,name,created_at');
}
]);
}
return $query;
}
/**
* 复杂查询条件构建
*/
public function scopeComplexWhere($query, array $filters)
{
foreach ($filters as $field => $condition) {
if (is_array($condition)) {
// 范围查询
if (isset($condition['min']) && isset($condition['max'])) {
$query->whereBetween($field, [$condition['min'], $condition['max']]);
}
// IN查询
elseif (isset($condition['in'])) {
$query->whereIn($field, $condition['in']);
}
} else {
// 精确匹配
$query->where($field, $condition);
}
}
return $query;
}
}
// 在模型中使用
namespace appcommonmodel;
use thinkModel;
use commontraitModelQueryTrait;
class User extends Model
{
use ModelQueryTrait;
// 复杂查询示例
public static function searchUsers(array $filters, int $page = 1)
{
return self::complexWhere($filters)
->withOptimized(['profile', 'orders'])
->paginateOptimized($page);
}
}实战案例：电商系统架构实现
1. 订单业务领域实现
<?php
// domain/order/OrderDomainService.php
namespace domainorder;
use domainorderentityOrderEntity;
use domainorderrepositoryOrderRepository;
use domainproductProductDomainService;
use domainuserUserDomainService;
class OrderDomainService
{
protected $orderRepository;
protected $productService;
protected $userService;
public function __construct(
OrderRepository $orderRepository,
ProductDomainService $productService,
UserDomainService $userService
) {
$this->orderRepository = $orderRepository;
$this->productService = $productService;
$this->userService = $userService;
}
/**
* 创建订单 - 复杂的业务逻辑
*/
public function createOrder(array $orderData): OrderEntity
{
// 1. 验证用户
$user = $this->userService->getUserById($orderData['user_id']);
if (!$user || !$user->isActive()) {
throw new Exception('用户状态异常');
}
// 2. 验证商品库存
foreach ($orderData['items'] as $item) {
if (!$this->productService->checkStock($item['product_id'], $item['quantity'])) {
throw new Exception("商品 {$item['product_id']} 库存不足");
}
}
// 3. 计算价格
$totalAmount = $this->calculateTotalAmount($orderData['items']);
$discountAmount = $this->calculateDiscount($user, $totalAmount);
$finalAmount = $totalAmount - $discountAmount;
// 4. 创建订单实体
$order = new OrderEntity();
$order->setUserId($orderData['user_id']);
$order->setTotalAmount($totalAmount);
$order->setDiscountAmount($discountAmount);
$order->setFinalAmount($finalAmount);
$order->setStatus(OrderEntity::STATUS_PENDING);
$order->setOrderItems($orderData['items']);
// 5. 保存订单（事务处理）
Db::transaction(function() use ($order, $orderData) {
// 保存订单
$savedOrder = $this->orderRepository->save($order);
// 扣减库存
foreach ($orderData['items'] as $item) {
$this->productService->decreaseStock(
$item['product_id'],
$item['quantity']
);
}
// 记录订单日志
$this->logOrderCreation($savedOrder);
});
return $order;
}
private function calculateTotalAmount(array $items): float
{
$total = 0;
foreach ($items as $item) {
$product = $this->productService->getProduct($item['product_id']);
$total += $product->getPrice() * $item['quantity'];
}
return $total;
}
private function calculateDiscount($user, float $totalAmount): float
{
if ($user->isVip()) {
return $totalAmount * 0.1; // VIP用户9折
}
if ($totalAmount > 1000) {
return 50; // 满1000减50
}
return 0;
}
}部署与监控
1. 生产环境配置
// .env.production
APP_DEBUG = false
APP_TRACE = false
# 数据库配置
DATABASE_HOST = 127.0.0.1
DATABASE_NAME = production_db
DATABASE_USERNAME = app_user
DATABASE_PASSWORD = secure_password
# Redis配置
REDIS_HOST = 127.0.0.1
REDIS_PORT = 6379
REDIS_PASSWORD = redis_password
# 缓存配置
CACHE_TYPE = redis
CACHE_EXPIRE = 3600
# 日志配置
LOG_TYPE = file
LOG_LEVEL = error2. 性能监控中间件
<?php
// common/middleware/PerformanceMonitor.php
namespace commonmiddleware;
use thinkRequest;
use thinkResponse;
use thinkfacadeLog;
class PerformanceMonitor
{
public function handle(Request $request, Closure $next)
{
$startTime = microtime(true);
$startMemory = memory_get_usage();
$response = $next($request);
$endTime = microtime(true);
$endMemory = memory_get_usage();
$executionTime = round(($endTime - $startTime) * 1000, 2);
$memoryUsage = round(($endMemory - $startMemory) / 1024 / 1024, 2);
// 记录性能日志
$this->logPerformance($request, $executionTime, $memoryUsage);
// 添加性能头信息（开发环境）
if (app()->isDebug()) {
$response->header([
'X-Execution-Time' => $executionTime . 'ms',
'X-Memory-Usage' => $memoryUsage . 'MB'
]);
}
return $response;
}
private function logPerformance(Request $request, float $time, float $memory): void
{
$logData = [
'url' => $request->url(),
'method' => $request->method(),
'ip' => $request->ip(),
'execution_time' => $time,
'memory_usage' => $memory,
'user_agent' => $request->header('user-agent')
];
// 慢请求警告
if ($time > 1000) {
Log::warning('Slow request detected', $logData);
}
// 高内存使用警告
if ($memory > 50) {
Log::warning('High memory usage detected', $logData);
}
Log::info('Request performance', $logData);
}
}总结与架构演进建议
通过本教程，我们构建了一个基于ThinkPHP 6.x的企业级应用架构：
- 多应用模式：实现业务逻辑的清晰分离
- 领域驱动设计：将复杂业务逻辑封装在领域层
- 仓储模式：实现数据访问与业务逻辑的解耦
- 中间件架构：提供灵活的横切关注点处理
- 服务容器：实现依赖注入和控制反转
架构演进建议：
- 从单体应用开始，逐步拆分为多应用架构
- 优先实现核心业务的领域模型
- 根据团队规模选择合适的模块化程度
- 建立完善的监控和日志系统
- 持续重构，保持架构的清洁和可维护性
