Spring Security：在Servlet过滤器中访问当前经过身份验证的用户

内部

doFilter

HttpServletRequest request = (HttpServletRequest) request;HttpSession session = request.getSession(false);SecurityContextImpl sci = (SecurityContextImpl) session.getAttribute("SPRING_SECURITY_CONTEXT");if (sci != null) {        UserDetails cud = (UserDetails) sci.getAuthentication().getPrincipal();        // do whatever you need here with the UserDetails}

希望这可以帮助
