我已经搜索了很多这个具体的问题,目前没有解决它的方法对我的项目有效。我使用的是spring启动安全性v.2.7.0和thymeleaf-临时安全5。问题是,我想在这样的网页上显示用户的名字:
<div sec:authorize="isAuthenticated()">
Welcome <span sec:authentication="name">Username</span>
</div>
证券交易委员会是:
<html lang="en" xmlns:th="http://www.thymeleaf.org" xmlns="http://www.w3.org/1999/html"
xmlns:sec="https://www.thymeleaf.org/thymeleaf-extras-springsecurity5">
我试图在我的控制器中显示用户的名称,它的工作方式与预期的一样:
@GetMapping("")
public String showHomePage(){
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
System.out.println("username: " + auth.getName());
return "index";
}例如,名为"admin“的用户登录:
username: admin但是它在网页上显示“欢迎用户名”。我唯一的猜测是
xmlns:sec="https://www.thymeleaf.org/thymeleaf-extras-springsecurity5" 是404这就是问题所在吗?如果是,有效链接是什么?
UPD:这是依赖项:

问题在于您的依赖关系。您正在将Spring版本3.0.0-快照与SpringBoot2.7.0混合使用。由于几个原因,这是行不通的,主要原因是3.0.0用于JakartaEE,而ST2.7.0用于JavaEE。不同的API,不同的实现和完全不兼容。
这也意味着您正在为JakartaEE 而不是 JavaEE使用Thymeleaf版本。您所包含的版本是针对较早版本的Thymeleaf,现在将被忽略。
修好你的水壶。不要使用Spring 3.0.0,因为这甚至不是2.7.0的最后一次。
