身份验证后重定向到受保护的页面

身份验证后重定向到受保护的页面

在我的项目中，我用

DefaultSavedRequest

它满足了我的要求。

DefaultSavedRequest

成功认证后，AbstractAuthenticationProcessingFilter和SavedRequestAwareWrapper使用该类重现请求。ExceptionTranslationFilter在身份验证异常时存储此类的实例。

@Overridepublic void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication)         throws IOException, ServletException {    DefaultSavedRequest defaultSavedRequest = (DefaultSavedRequest) session.getAttribute("SPRING_SECURITY_SAVED_REQUEST");    if(defaultSavedRequest != null){       String targetURL = defaultSavedRequest.getRedirectUrl();       redirectStrategy.sendRedirect(request, response, targetURL);       return;    }}
