推荐答案
使用身份验证标签
当然，没有必要使用 JSP标签用于这种情况，并且 有些人宁愿少存钱 在视图中尽可能的逻辑.你可以 访问身份验证对象 您的MVC控制器(通过调用 SecurityContextHolder.getContext().getAuthentication()) 并将数据直接添加到您的 用于通过视图呈现的模型.
Of course, it isn't necessary to use JSP tags for this kind of thing and some people prefer to keep as little logic as possible in the view. You can access the Authentication object in your MVC controller (by calling SecurityContextHolder.getContext().getAuthentication()) and add the data directly to your model for rendering by the view.
