你看过《Spring》吗？HttpSession & RestfulAPI，使用HTTP头而不是cookie。请参阅REST示例中的REST示例项目。

基于表单的登录主要是有状态会话。在您的场景中，最好使用无状态会话。
JWT为此提供了实现。它基本上是一个键，你需要在每个HTTP请求中作为头传递。只要你有钥匙。API可用。
我们可以将JWT与Spring集成。
基本上你需要写这些逻辑。

• 生成密钥逻辑
• 在Spring Security中使用JWT
• 每次呼叫时按下按键

您可以在网站DomainB.com服务器和客户端浏览器之间进行基于令牌的通信。令牌可以在身份验证后从DomainB.com服务器在响应的标头中发送。然后客户端浏览器可以将令牌保存在本地存储/会话存储中（也有到期时间）。然后客户端可以在每个请求的报头中发送令牌。希望这对你有帮助。

我很感激上面的所有答案-我最终选择了一个更简单的解决方案，而没有做任何应用程序级别的更改，因为www.example.com的所有者domainA.com愿意与我们合作。在这里贴给别人，因为我甚至没有想到这一点最初.
基本上：

• domainA.com的所有者为domainB.domainA.com-> domainB.com创建了DNS记录
• domainB.com的所有者（我）通过“电子邮件验证”为domainB.domainA.com请求了一个公共SSL证书（我通过AWS这样做，但我相信还有其他机制通过其他提供商）
• 上述请求已发送给domainA.com的网站管理员->他们批准并颁发了公共证书
• 一旦颁发-我能够配置我的应用程序（或负载均衡器）使用这个新证书，他们配置他们的应用程序指向“domainB.domainA.com“（随后在DNS中路由到domainB.com）
• 现在，浏览器为domainB.domainA.com发出cookie，由于它们是相同的主域，因此无需任何变通方法即可创建cookie。

再次感谢您的回答，抱歉没有在这里选择答案-忙碌周。
