Java 身份验证后重定向到受保护页面

默认情况下，spring security after authentication会将您重定向到之前尝试访问的受保护页面

当我实现自己的成功处理程序时

@Component
class MyS: AuthenticationSuccessHandler {
    override fun onAuthenticationSuccess(request: HttpServletRequest?, response: HttpServletResponse?, authentication: Authentication?) {

        response?.sendRedirect(request?.getHeader(HttpHeaders.REFERER))

    }
}

---

我不能达到同样的效果。我尝试重定向到referer，但在本例中referer是/en/login页面

基本上：

用户尝试访问受保护的url

/protected

将用户重定向到

/login

页面

身份验证后，应再次将用户重定向到

/protected

如何使用自定义successHandler？在我的项目中，我使用了满足我要求的

DefaultSavedRequest

DefaultSavedRequest

类由AbstractAuthenticationProcessingFilter和SavedRequestAwareWrapper用于在成功身份验证后复制请求。ExceptionTranslationFilter在发生身份验证异常时存储此类的实例

多亏了Mhod的回答，这就成功了

@Component
class MyS: AuthenticationSuccessHandler {
    override fun onAuthenticationSuccess(request: HttpServletRequest?, response: HttpServletResponse?, authentication: Authentication?) {

        val defaultSavedRequest = request?.session?.getAttribute("SPRING_SECURITY_SAVED_REQUEST") as DefaultSavedRequest
        response?.sendRedirect(defaultSavedRequest.requestURI)

    }
}

@Override
public 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;
    }
}

@Component
class MyS: AuthenticationSuccessHandler {
    override fun onAuthenticationSuccess(request: HttpServletRequest?, response: HttpServletResponse?, authentication: Authentication?) {

        val defaultSavedRequest = request?.session?.getAttribute("SPRING_SECURITY_SAVED_REQUEST") as DefaultSavedRequest
        response?.sendRedirect(defaultSavedRequest.requestURI)

    }
}
