我们如何构建一个 spring mvc 多租户应用程序，使用 hibernate 作为 orm 独立的数据库和模式
how can we build a spring mvc multitenant application using hibernate as orm separate database and schema
从 spring io 你转移到堆栈溢出但是你没有解释多租户完整的演示应用程序，它可以被视为一个问题解决者事实上没有人对你的答案感到满意你现在可以分享一个工作多租户模式和独立数据库完整代码的演示，人们可以在任何地方使用它

以上错误表明未指定租户标识符。请仔细检查您的配置和标识符 class 实现名称。
您收到此错误的原因是您的租户标识符解析器需要 return 一些默认值，以防它无法从您选择的策略中找到合适的租户 ID（在您的情况下，您正在尝试获取来自请求参数的租户 ID）。我使用了下面更新的代码，它不再显示错误。
public class CurrentTenantIdentifierResolverimpl implements CurrentTenantIdentifierResolver {
@Override
public String resolveCurrentTenantIdentifier() {
ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
String tenantId = attr.getRequest().getParameter("tenantId");
if (tenantId==null) {
//return default tenant
return "tenantId1";
}
return tenantId;
}
@Override
public boolean validateExistingCurrentSessions() {
return true;
}

Shailendra 先生，我们如何在不设置默认 ID 的情况下为其设置租户 ID，并从 spring 安全部门获取用户名并将其传递给租户 ID
