Php 如何在yii2中使用不同的数据库创建多个登录访问？

您好，我正在为我的公司创建web报告管理。有3个数据库登录，所以我需要做3个不同的登录功能。问题是，当应用程序登录时，它试图用每个实现identityInterface的类查找DidEntity。 比如我有

FORM A -> Login to Mysql
FORM B -> Login to Postgresql
FORM C -> Login to Mysql

当我使用表单A登录时，另一个表单B和表单C也会登录

这是我的配置

<?php

我认为您应该专门化您的类，以便根据您希望访问的数据库返回正确的数据库实例（getDB）。
例如，您可以通过调用由各种“登录”区分的操作来执行此操作，并在此操作中将对象分配给您感兴趣的正确数据库实例。
有任何示例吗？我真的不明白你在说什么
