重写laravel DatabaseManager方法可以通过创建一个自定义的DatabaseManager类来实现。下面是一个示例的重写方法:
use Illuminate\Database\DatabaseManager as BaseDatabaseManager;
class CustomDatabaseManager extends BaseDatabaseManager
{
/**
* Get a database connection instance.
*
* @param string $name
* @return \Illuminate\Database\Connection
*/
public function connection($name = null)
{
// 自定义的连接逻辑
// ...
// 调用父类的connection方法获取连接实例
return parent::connection($name);
}
}
// config/database.php
return [
// ...
'connections' => [
'mysql' => [
'driver' => 'custom', // 使用自定义的数据库驱动
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
],
'migrations' => 'migrations',
// ...
'custom' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
// ...
];
通过以上步骤,你可以重写laravel的DatabaseManager方法,并在自定义的方法中实现你的逻辑。请注意,以上示例仅为演示目的,实际的重写方法可能因具体需求而有所不同。
