使用Composer安装

1. 运行命令 composer require stefano/stefano-nested-transaction

特性

• 管理嵌套事务

使用方法

• 配置

//$transactionAdapter implements \StefanoNestedTransaction\Adapter\TransactionInterface
$transactionAdapter = new YourTransactionAdapter();

$transactionManager = new \StefanoNestedTransaction\TransactionManager($transactionAdapter);

• 示例：正常流程

$transactionManager->begin(); //REAL start transaction
try {
    // ...

    //nested transaction block, that might be in some other code
    $transactionManager->begin(); //increase internal transaction counter
    try {
        // ...

        $transactionManager->commit(); //decrease internal transaction counter
    } catch(\Exception $e) {
        $transactionManager->rollback(); //skipped
        throw $e->getPrevious();
    }

    // ...
    $transactionManager->commit(); //REAL commit transaction;
} catch(\Exception $e) {
    $transactionManager->rollback(); //skipped
    throw $e->getPrevious();
}

• 示例：抛出异常

$transactionManager->begin(); //REAL start transaction
try {
    // ...

    //nested transaction block, that might be in some other code
    $transactionManager->begin(); //increase internal transaction counter
    try {
        // ...

        throw new \Exception();

        $transactionManager->commit(); //skipped
    } catch(\Exception $e) {
        $transactionManager->rollback(); //marked as rollback only
        throw $e->getPrevious();
    }

    // ...
    $transactionManager->commit(); //skipped
} catch(\Exception $e) {
    $transactionManager->rollback(); //REAL rollback
    throw $e->getPrevious();
}

• 示例：抛出异常

$transactionManager->begin(); //REAL start transaction
try {
    // ...

    //nested transaction block, that might be in some other code
    $transactionManager->begin(); //increase internal transaction counter
    try {
        // ...

        throw new \Exception();

        $transactionManager->commit(); //do nothing
    } catch(\Exception $e) {
        $transactionManager->rollback(); //marked as rollback only
    }

    // ...
    $transactionManager->commit(); //this throw exception because transaction is marked as rollback only
} catch(\Exception $e) {
    $transactionManager->rollback(); //REAL rollback
    throw $e->getPrevious();
}
