Symfony 4 EntityManager 多数据库

Question

我想在我的 APP\Repository 文件中使用多个数据库执行 SQL 请求。

我找到了这个，但它只适用于 APP\Controller 文件。

Symfony multiple Entity Managers and Connections

但无法在存储库文件中执行 $this->getDoctrine()->getManager('database1')

这是我的代码：

App\Repository

public function __construct(EntityManagerInterface $em)
{

    $this->em = $em;
}

/**
 * @param string $code
 * @return mixed[]
 * @throws DBALException
 */
function Getdata(string $code) {

    // I would be able to execute $sql with my DATABASE2
    $sql = "SELECT * FROM api";
    $conn = $this->em->getConnection();
    $query = $conn->prepare($sql);
    $query->execute();
    $result = $query->fetchAll();
    return($result);
}

/config/services.yaml

doctrine:
dbal:
    default_connection: default
    connections:
        default:
            # configure these for your database server
            url: '%env(DATABASE1)%'
            driver: 'pdo_mysql'
            server_version: '5.7'
            charset: utf8mb4
        customer:
            # configure these for your database server
            url: '%env(DATABASE2)%'
            driver: 'pdo_mysql'
            server_version: '5.7'
            charset: utf8mb4

提前感谢您的回答，如果我不清楚，请随时提问

这是我实现的，可以提供帮助：

App\Repository

public function __construct(ManagerRegistry $mr)
{
    $this->mr = $mr;
}

function Getdata() {
        $em = $this->mr->getManager("db1");
        $sql = "SELECT * FROM table"
        $conn = $em->getConnection();
        $query = $conn->prepare($sql);
        $query->execute();
        return ($query);
}

/config/doctrine.yaml

doctrine:
    dbal:
        default_connection:       db1
        connections:
            db1:
                url: '%env(DB1)%'
                driver: pdo_mysql
                server_version: 'mariadb-10.4.7'

            db2:
                url: '%env(DB2)%'
                driver: pdo_mysql
                server_version: 'mariadb-10.4.7'
    orm:
        auto_generate_proxy_classes: true
        entity_managers:
            db1:
                connection: db1
                mappings:
                    App:
                        is_bundle: false
                        type: annotation
                        dir: '%kernel.project_dir%/src/Entity'
                        prefix: 'App\Entity'
            db2:
                connection: db2
                mappings:
                    Customer:
                        is_bundle: false
                        type: annotation
                        dir: '%kernel.project_dir%/src/Entity/'
                        prefix: 'App\Entity'
