+# Hyperf Service — 代码模板
+
+> 主流程见 SKILL.md，本文档为 Service/Repository/Event/Logger/Retry 完整实现。
+
+## Service 模板
+
+```php
+<?php
+namespace App\Service\{{Domain}};
+
+use App\Model\{{Domain}}\{{Module}};
+use App\Repository\{{Domain}}\{{Module}}Repository;
+use App\Exception\BusinessException;
+use Hyperf\DbConnection\Db;
+use Hyperf\Di\Annotation\Inject;
+
+class {{Module}}Service
+{
+    #[Inject]
+    protected {{Module}}Repository $repository;
+
+    public function getPageList(array $params): array { return $this->repository->getPageList($params); }
+
+    public function getById(int $id): {{Module}} {
+        $record = {{Module}}::find($id);
+        if (!$record) throw new BusinessException(404, '{{Module}} not found');
+        return $record;
+    }
+
+    public function create(array $data): {{Module}} {
+        return Db::transaction(function () use ($data) {
+            $record = {{Module}}::create($data);
+            return $record;
+        });
+    }
+
+    public function update(int $id, array $data): {{Module}} {
+        $record = $this->getById($id);
+        return Db::transaction(function () use ($record, $data) {
+            $record->update($data);
+            return $record->refresh();
+        });
+    }
+
+    public function delete(int $id): void {
+        $record = $this->getById($id);
+        Db::transaction(fn () => $record->delete());
+    }
+}
+```
+
+## Repository 模板（含 applyFilters / applyDataScope）
+
+```php
+class {{Module}}Repository
+{
+    public function getPageList(array $params): array {
+        $query = {{Module}}::query();
+        $this->applyFilters($query, $params);
+        $this->applyDataScope($query);
+        $page = (int) ($params['page'] ?? 1);
+        $pageSize = min((int) ($params['page_size'] ?? 10), 100);
+        $total = $query->count();
+        $items = $query->with($this->getDefaultRelations())->orderByDesc('id')
+            ->offset(($page - 1) * $pageSize)->limit($pageSize)->get();
+        return ['items' => $items, 'total' => $total];
+    }
+
+    protected function applyFilters(Builder $query, array $params): void {
+        if (!empty($params['keyword'])) $query->where('name', 'like', "%{$params['keyword']}%");
+        if (!empty($params['status'])) $query->where('status', $params['status']);
+    }
+
+    protected function applyDataScope(Builder $query): void { /* 数据权限 */ }
+    protected function getDefaultRelations(): array { return []; }
+}
+```
+
+## Event + Listener 模板
+
+```php
+// Event
+class {{Module}}Created { public function __construct(public readonly {{Module}} $record) {} }
+
+// Listener
+#[Listener]
+class {{Module}}CreatedListener implements ListenerInterface
+{
+    public function listen(): array { return [{{Module}}Created::class]; }
+    public function process(object $event): void { /* 发送通知、更新缓存等 */ }
+}
+```
+
+## HasLogger Trait
+
+```php
+trait HasLogger {
+    protected ?LoggerInterface $logger = null;
+    protected function logger(): LoggerInterface { /* 按类名获取 channel */ }
+    protected function logContext(array $extra = []): array { return array_merge(['request_id' => Context::get('request_id'), 'user_id' => Context::get('current_user_id')], $extra); }
+}
+```
+
+## RetryHelper
+
+```php
+public static function withRetry(callable $fn, int $maxRetries = 3, int $baseDelayMs = 1000, array $retryOn = []): mixed {
+    for ($attempt = 0; $attempt <= $maxRetries; $attempt++) {
+        try { return $fn(); }
+        catch (\Throwable $e) {
+            if ($attempt < $maxRetries) Coroutine::sleep(($baseDelayMs * (2 ** $attempt) + jitter) / 1000);
+            else throw $e;
+        }
+    }
+}
+```
+
+## RequestIdMiddleware
+
+在 process 中：`Context::set('request_id', $requestId)`，响应头加 `X-Request-ID`。
