【问题讨论】：
错误信息中的“with root cause”后面是什么？这可能会告诉你根本原因。 我已经更新了错误信息 【参考方案1】：您的错误消息显示Neither BindingResult nor plain target object for bean name 'register' available as request attribute。如果您查看 getLoginForm 方法，您只会填充“登录”对象，而不是模型中的“注册”对象。如果您想在一页上使用两个表单，我认为您需要一个 method = RequestMethod.GET 方法来填充两个表单的默认值。无论何时显示此页面，您都需要确保填充了两个表单支持对象。
【讨论】：
这意味着两个表单都在 /login 下，我希望第一个表单在 /login 下，第二个表单在 /register以上是关于在同一个html页面中处理thymeleaf两种形式给出错误的主要内容，如果未能解决你的问题，请参考以下文章
