统一契约层<?php // app/Integration/Contract/ErpDataSourceInterface.php namespace App\Integration\Contract;/** * 所有 ERP 模块实现此契约，报表系统面向接口编程 * 新增模块只需实现接口，零改动报表核心 */ interface ErpDataSourceInterface{publicfunctionfetchBatch(QueryContext$ctx):\Generator;// 游标分页 publicfunctionschema(): array;// 字段元数据 publicfunctionsupportedFilters(): array;// 可用过滤条件}<?php // app/Integration/Contract/QueryContext.php namespace App\Integration\Contract;use Hyperf\Context\Context;final class QueryContext{publicfunction__construct(publicreadonlyint$tenantId, publicreadonlyarray$filters, publicreadonlyarray$fields, publicreadonlyint$lastId=0, publicreadonlyint$pageSize=5000,){}public staticfunctionfromRequest(array$params): self{$auth=Context::get('auth');returnnew self(tenantId:$auth['tenant_id'], filters:$params['filters']??[], fields:$params['fields']??['*'],);}}<?php // app/Integration/Erp/SalesDataSource.php namespace App\Integration\Erp;use App\Integration\Contract\ErpDataSourceInterface;use App\Integration\Contract\QueryContext;use Hyperf\DbConnection\Db;class SalesDataSource implements ErpDataSourceInterface{publicfunctionfetchBatch(QueryContext$ctx):\Generator{$lastId=$ctx->lastId;do{$rows=Db::connection('erp')// 独立 ERP 连接池 ->table('erp_sales_orders as s')->join('erp_customers as c','c.id','s.customer_id')->where('s.tenant_id',$ctx->tenantId)->where('s.id','>',$lastId)->where($this->buildFilters($ctx->filters))->orderBy('s.id')->limit($ctx->pageSize)->get();if($rows->isEmpty())break;$lastId=$rows->last()->id;yield$rows->all();}while($rows->count()===$ctx->pageSize);}publicfunctionschema(): array{return['order_no'=>['type'=>'string','label'=>'订单号'],'customer_name'=>['type'=>'string','label'=>'客户名称'],'amount'=>['type'=>'decimal','label'=>'金额'],'status'=>['type'=>'enum','label'=>'状态','values'=>['pending','paid','cancelled']],'created_at'=>['type'=>'datetime','label'=>'下单时间'],];}publicfunctionsupportedFilters(): array{return['date_range','customer_id','status','amount_range'];}privatefunctionbuildFilters(array$filters): array{$where=[];isset($filters['status'])&&$where[]=['s.status','=',$filters['status']];isset($filters['date_range'])&&$where[]=['s.created_at','>=',$filters['date_range'][0]];isset($filters['date_range'])&&$where[]=['s.created_at','<=',$filters['date_range'][1]];return$where;}}--- 二、数据映射 — 字段标准化<?php // app/Integration/Mapper/ErpFieldMapper.php namespace App\Integration\Mapper;use Hyperf\DbConnection\Db;/** * 解决核心挑战：ERP 各模块字段命名混乱、类型不一致 * 映射规则存 DB，运营可配置，无需改代码 */ class ErpFieldMapper{// 映射规则缓存 private array$rules=[];publicfunctionload(int$templateId): void{$key="field_map:{$templateId}";if($cached=redis()->get($key)){$this->rules=unserialize($cached);return;}$this->rules=Db::table('field_mappings')->where('template_id',$templateId)->get(['source_field','target_field','transform','default_value'])->keyBy('source_field')->toArray();redis()->setex($key,600, serialize($this->rules));}publicfunctionmap(object$row): array{$result=[];foreach($this->rules as$src=>$rule){$val=$row->$src??$rule['default_value'];$result[$rule['target_field']]=$this->transform($val,$rule['transform']);}return$result;}privatefunctiontransform(mixed$val, ?string$transform): mixed{returnmatch($transform){'yuan_to_fen'=>(int)bcmul((string)$val,'100'),'fen_to_yuan'=>bcdiv((string)$val,'100',2),'timestamp'=>date('Y-m-d H:i:s',(int)$val),'status_label'=>$this->statusLabel($val),null=>$val,default=>$val,};} private function statusLabel(mixed $val):string { return ['pending'=>'待处理','paid'=>'已付款','cancelled'=>'已取消'][$val]??$val;} }--字段映射配置表（运营可维护） CREATE TABLE field_mappings(id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,template_id INT UNSIGNED NOT NULL,source_field VARCHAR(64)NOT NULL,--ERP 原始字段 target_field VARCHAR(64)NOT NULL,--报表展示字段 transform VARCHAR(32),--转换规则 default_value VARCHAR(128),sort_order TINYINT NOT NULL DEFAULT0,INDEX idx_tpl(template_id));---三、事务边界 — Saga 补偿模式<?php//app/Integration/Saga/ReportGenerateSaga.php namespace App\Integration\Saga;use Hyperf\DbConnection\Db;/***跨模块事务核心挑战：*ERP DB 与报表 DB 不在同一数据源，无法用本地事务*方案：Saga 补偿 — 每步记录，失败逆序补偿*/class ReportGenerateSaga { private array $compensations=[];//补偿栈（LIFO） public function run(string $taskId,array $params):void { try {//Step1:锁定 ERP 数据快照 $snapshotId=$this->lockErpSnapshot($taskId,$params);$this->compensations[]=fn()=>$this->releaseSnapshot($snapshotId);//Step2:创建报表任务 $this->createReportTask($taskId,$snapshotId);$this->compensations[]=fn()=>$this->cancelReportTask($taskId);//Step3:扣减导出配额 $this->deductQuota($params['tenant_id']);$this->compensations[]=fn()=>$this->refundQuota($params['tenant_id']);//Step4:触发异步生成 $this->dispatchGenerate($taskId,$snapshotId);} catch(\Throwable $e){ $this->compensate();//逆序回滚 throw $e;} } private function lockErpSnapshot(string $taskId,array $params):int { return Db::connection('erp')->table('data_snapshots')->insertGetId([ 'task_id'=>$taskId,'params'=>json_encode($params),'locked_at'=>time(),'expire_at'=>time()+3600,]);} private function createReportTask(string $taskId,int $snapshotId):void { Db::table('report_tasks')->insert([ 'id'=>$taskId,'snapshot_id'=>$snapshotId,'status'=>'pending','created_at'=>time(),]);} private function deductQuota(int $tenantId):void { $affected=Db::table('tenant_quotas')->where('tenant_id',$tenantId)->where('remaining','>',0)->decrement('remaining');if(!$affected)throw new \RuntimeException('导出配额不足');} private function dispatchGenerate(string $taskId,int $snapshotId):void { make(\Hyperf\AsyncQueue\Driver\DriverFactory::class)->get('default')->push(new \App\Job\ReportJob($taskId,['snapshot_id'=>$snapshotId]));}// 补偿操作 privatefunctionreleaseSnapshot(int$id): void{Db::connection('erp')->table('data_snapshots')->where('id',$id)->delete();}privatefunctioncancelReportTask(string$id): void{Db::table('report_tasks')->where('id',$id)->update(['status'=>'cancelled']);}privatefunctionrefundQuota(int$tenantId): void{Db::table('tenant_quotas')->where('tenant_id',$tenantId)->increment('remaining');}privatefunctioncompensate(): void{foreach(array_reverse($this->compensations)as$fn){try{$fn();}catch(\Throwable){/* 补偿失败记日志，不中断其他补偿 */}}}}--- 四、AMQP 事件驱动 — ERP 数据变更同步<?php // app/Integration/Consumer/ErpDataChangedConsumer.php namespace App\Integration\Consumer;use Hyperf\Amqp\Annotation\Consumer;use Hyperf\Amqp\Message\ConsumerMessage;use Hyperf\Amqp\Result;use Hyperf\DbConnection\Db;#[Consumer(exchange:'erp.events', routingKey:'data.changed.*', queue:'report.sync', nums:2,)]class ErpDataChangedConsumer extends ConsumerMessage{publicfunctionconsumeMessage(mixed$data,\PhpAmqpLib\Message\AMQPMessage$message): Result{// ERP 数据变更 → 失效相关报表缓存 → 触发增量同步 match($data['event']){'sales.order.updated'=>$this->invalidateCache('sales',$data['tenant_id']),'finance.bill.created'=>$this->invalidateCache('finance',$data['tenant_id']),'inventory.stock.changed'=>$this->invalidateCache('inventory',$data['tenant_id']), default=>null,};returnResult::ACK;}privatefunctioninvalidateCache(string$module, int$tenantId): void{// 失效该租户该模块的查询缓存$pattern="qry:{$module}:{$tenantId}:*";$keys=redis()->keys($pattern);$keys&&redis()->del(...$keys);// 记录数据变更时间戳，报表生成时判断是否需要刷新快照 redis()->setex("data_version:{$module}:{$tenantId}",86400, time());}}--- 五、集成注册中心 — 模块自动发现<?php // app/Integration/DataSourceRegistry.php namespace App\Integration;use App\Integration\Contract\ErpDataSourceInterface;use Hyperf\Di\Annotation\Inject;class DataSourceRegistry{// 依赖注入容器自动解析所有实现 private array$sources=[];publicfunctionregister(string$module, ErpDataSourceInterface$source): void{$this->sources[$module]=$source;}publicfunctionget(string$module): ErpDataSourceInterface{return$this->sources[$module]?? throw new\InvalidArgumentException("未注册的 ERP 模块: {$module}");}publicfunctionall(): array{return$this->sources;}}<?php // config/autoload/dependencies.php — 模块注册return[\App\Integration\DataSourceRegistry::class=>function($container){$registry=new\App\Integration\DataSourceRegistry();$registry->register('sales',$container->get(\App\Integration\Erp\SalesDataSource::class));$registry->register('finance',$container->get(\App\Integration\Erp\FinanceDataSource::class));$registry->register('inventory',$container->get(\App\Integration\Erp\InventoryDataSource::class));return$registry;},];--- 六、报表生成服务 — 组装完整链路<?php // app/Service/ErpReportService.php namespace App\Service;use App\Integration\DataSourceRegistry;use App\Integration\Mapper\ErpFieldMapper;use App\Integration\Contract\QueryContext;use App\Integration\Saga\ReportGenerateSaga;use OpenSpout\Writer\XLSX\Writer;use OpenSpout\Common\Entity\Row;class ErpReportService{publicfunction__construct(privatereadonlyDataSourceRegistry$registry, privatereadonlyErpFieldMapper$mapper, privatereadonlyReportGenerateSaga$saga,){}publicfunctionsubmit(array$params): string{$taskId=uniqid('erp_',true);$this->saga->run($taskId,$params);// Saga 保证跨模块一致性return$taskId;}publicfunctiongenerate(string$taskId, array$params): string{$source=$this->registry->get($params['module']);$ctx=QueryContext::fromRequest($params);$this->mapper->load($params['template_id']);$path="/tmp/reports/{$taskId}.xlsx";$writer=new Writer();$writer->openToFile($path);// 表头来自 schema，自动适配各模块$headers=array_column($source->schema(),'label');$writer->addRow(Row::fromValues($headers));foreach($source->fetchBatch($ctx)as$batch){$writer->addRows(array_map(fn($r)=>Row::fromValues(array_values($this->mapper->map($r))),$batch));unset($batch);}$writer->close();return$path;}}---
