我的 @PreAuthorize 注释不起作用。从我可以看到我做的正确。请注意，这是对我删除的帖子的更新，因为我意识到我应该复制整个 xml 文件而不是片段。
这是我的 security-context.xml
<?xml version="1.0" encoding="UTF-8"?>

这是 root-context.xml，它是 web.xml 中上下文参数的一部分。注意 root-context.xml 导入 security-context.xml：

而我的实际注释：
@PreAuthorize("isAuthenticated()")
@RequestMapping(params = "form", method = RequestMethod.GET)
public String createForm(Model uiModel) {
Contact contact = new Contact();
uiModel.addAttribute("contact", contact);
return "contacts/create";
}
