// config/database.php
'pgsql' => [
'driver' => 'pgsql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),

'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'prefix' => '',
'prefix_indexes' => true,
'search_path' => 'public',
'sslmode' => 'prefer',
],
数据模型设计与实现
创建Eloquent模型
# 创建用户模型
php artisan make:model User -m
# 创建产品模型
php artisan make:model Product -m
# 创建订单模型
php artisan make:model Order -m
用户模型定义
<?php
// app/Models/User.php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\HasMany;
class User extends Model
{
use HasFactory;
protected $table = 'users';
protected $primaryKey = 'user_id';
public $incrementing = true;
protected $fillable = [
'first_name',
'last_name',
'email',
'created_at',
'updated_at'
];
protected $casts = [
'created_at' => 'datetime',
'updated_at' => 'datetime',
];
/**
* 获取用户的订单
*/
public function orders(): HasMany
{
return $this->hasMany(Order::class, 'user_id', 'user_id');
}
}
数据库迁移文件
<?php
// database/migrations/2024_01_01_000000_create_users_table.php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateUsersTable extends Migration
{
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->id('user_id');
$table->string('first_name', 100);
$table->string('last_name', 100);
$table->string('email', 255)->unique();
$table->timestamps();
// 添加索引优化查询性能
$table->index('email');
$table->index(['first_name', 'last_name']);
});
}
public function down()
{
Schema::dropIfExists('users');
}
}
业务逻辑实现
服务层设计
<?php
// app/Services/UserService.php
namespace App\Services;
use App\Models\User;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Log;
class UserService
{
/**
* 创建用户（带事务处理）
*/
public function createUser(array $userData): User
{
return DB::transaction(function () use ($userData) {
try {
$user = User::create([
'first_name' => $userData['first_name'],
'last_name' => $userData['last_name'],
'email' => $userData['email']
]);
Log::info('用户创建成功', ['user_id' => $user->user_id]);
return $user;
} catch (\Exception $e) {
Log::error('用户创建失败', [
'error' => $e->getMessage(),
'data' => $userData
]);
throw $e;
}
});
}
/**
* 批量创建用户（优化性能）
*/
public function bulkCreateUsers(array $usersData): array
{
$createdUsers = [];
foreach (array_chunk($usersData, 100) as $chunk) {
$createdUsers = array_merge(
$createdUsers,
User::insert($chunk)
);
}
return $createdUsers;
}
}
控制器实现
<?php
// app/Http/Controllers/UserController.php
namespace App\Http\Controllers;
use App\Models\User;
use App\Services\UserService;
use Illuminate\Http\JsonResponse;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
class UserController extends Controller
{
protected $userService;
public function __construct(UserService $userService)
{
$this->userService = $userService;
}
/**
* 获取所有用户
*/
public function index(): JsonResponse
{
try {
$users = User::with('orders')
->orderBy('created_at', 'desc')
->paginate(20);
return response()->json([
'success' => true,
'data' => $users,
'message' => '用户列表获取成功'
]);
} catch (\Exception $e) {
return response()->json([
'success' => false,
'message' => '获取用户列表失败: ' . $e->getMessage()
], 500);
}
}
/**
* 创建新用户
*/
public function store(Request $request): JsonResponse
{
$validator = Validator::make($request->all(), [
'first_name' => 'required|string|max:100',
'last_name' => 'required|string|max:100',
'email' => 'required|email|unique:users,email'
]);
if ($validator->fails()) {
return response()->json([
'success' => false,
'errors' => $validator->errors()
], 422);
}
try {
$user = $this->userService->createUser($validator->validated());
return response()->json([
'success' => true,
'data' => $user,
'message' => '用户创建成功'
], 201);
} catch (\Exception $e) {
return response()->json([
'success' => false,
'message' => '用户创建失败: ' . $e->getMessage()
], 500);
}
}
}
高级查询优化
复杂查询示例
<?php
// app/Services/ReportService.php
namespace App\Services;
use App\Models\User;
use App\Models\Order;
use Illuminate\Support\Facades\DB;
use Carbon\Carbon;
class ReportService
{
/**
* 获取用户订单统计报告
*/
public function getUserOrderReport($startDate, $endDate)
{
return User::select([
'users.user_id',
'users.first_name',
'users.last_name',
'users.email',
DB::raw('COUNT(orders.order_id) as total_orders'),
DB::raw('SUM(orders.total_amount) as total_spent'),
DB::raw('MAX(orders.created_at) as last_order_date')
])
->leftJoin('orders', 'users.user_id', '=', 'orders.user_id')
->whereBetween('orders.created_at', [
Carbon::parse($startDate)->startOfDay(),
Carbon::parse($endDate)->endOfDay()
])
->groupBy('users.user_id', 'users.first_name', 'users.last_name', 'users.email')
->orderBy('total_spent', 'desc')
->having('total_orders', '>', 0)
->paginate(25);
}
/**
* 使用原生SQL进行复杂聚合查询
*/
public function getSalesAnalytics()
{
return DB::select("
SELECT
DATE(created_at) as sale_date,
COUNT(*) as order_count,
SUM(total_amount) as daily_revenue,
AVG(total_amount) as avg_order_value,
COUNT(DISTINCT user_id) as unique_customers
FROM orders
WHERE created_at >= NOW() - INTERVAL '30 days'
GROUP BY DATE(created_at)
ORDER BY sale_date DESC
");
}
}
性能优化策略
数据库索引优化
-- 为常用查询字段添加索引
CREATE INDEX idx_users_email ON users(email);
CREATE INDEX idx_users_name ON users(first_name, last_name);
CREATE INDEX idx_orders_user_date ON orders(user_id, created_at);
CREATE INDEX idx_orders_status ON orders(status);
-- 使用覆盖索引优化特定查询
CREATE INDEX idx_orders_covering ON orders (user_id, created_at) INCLUDE (total_amount, status);
Laravel查询优化技巧
<?php
// 优化后的查询示例
// 1. 使用select指定需要的字段
$users = User::select(['user_id', 'first_name', 'last_name', 'email'])
->where('active', true)
->get();
// 2. 使用with预加载关联数据（避免N+1查询）
$usersWithOrders = User::with(['orders' => function($query) {
$query->select('order_id', 'user_id', 'total_amount', 'created_at')
->where('status', 'completed')
->orderBy('created_at', 'desc');
}])->get();
// 3. 使用chunk处理大数据集
User::where('created_at', '>', now()->subDays(30))
->chunk(200, function ($users) {
foreach ($users as $user) {
// 处理每个用户
}
});
// 4. 使用cursor进行内存优化
foreach (User::where('active', true)->cursor() as $user) {
// 处理用户数据，内存使用更高效
}
错误处理与日志记录
统一异常处理
<?php
// app/Exceptions/Handler.php
namespace App\Exceptions;
use Illuminate\Database\QueryException;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Throwable;
class Handler extends ExceptionHandler
{
public function register()
{
$this->reportable(function (QueryException $e) {
// 处理数据库查询异常
if (str_contains($e->getMessage(), 'SQLSTATE')) {
\Log::error('数据库查询错误', [
'message' => $e->getMessage(),
'sql' => $e->getSql(),
'bindings' => $e->getBindings()
]);
}
});
$this->renderable(function (QueryException $e, $request) {
if ($request->expectsJson()) {
return response()->json([
'success' => false,
'message' => '数据库操作失败，请稍后重试',
'error_code' => 'DATABASE_ERROR'
], 500);
}
});
}
}
监控与日志配置
// config/logging.php
'channels' => [
'yugabyte' => [
'driver' => 'daily',
'path' => storage_path('logs/yugabyte.log'),
'level' => 'debug',
'days' => 14,
],
'database' => [
'driver' => 'daily',
'path' => storage_path('logs/database.log'),
'level' => 'info',
'days' => 30,
],
],
测试策略
单元测试示例
<?php
// tests/Feature/UserTest.php
namespace Tests\Feature;
use App\Models\User;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Tests\TestCase;
class UserTest extends TestCase
{
use RefreshDatabase;
/** @test */
public function it_can_create_a_user()
{
$userData = [
'first_name' => 'John',
'last_name' => 'Doe',
'email' => 'john.doe@example.com'
];
$response = $this->postJson('/api/users', $userData);
$response->assertStatus(201)
->assertJson([
'success' => true,
'data' => [
'first_name' => 'John',
'last_name' => 'Doe',
'email' => 'john.doe@example.com'
]
]);
$this->assertDatabaseHas('users', $userData);
}
/** @test */
public function it_validates_user_creation()
{
$response = $this->postJson('/api/users', []);
$response->assertStatus(422)
->assertJsonValidationErrors(['first_name', 'last_name', 'email']);
}
/** @test */
public function it_can_retrieve_users()
{
User::factory()->count(10)->create();
$response = $this->getJson('/api/users');
$response->assertStatus(200)
->assertJsonCount(10, 'data.data')
->assertJsonStructure([
'success',
'data' => [
'data' => [
'*' => ['user_id', 'first_name', 'last_name', 'email']
],
'links',
'meta'
]
]);
}
}
