@Service
public class AuthenticationSuccessHandler extends
SavedRequestAwareAuthenticationSuccessHandler {
该类中的onAuthenticationSuccess方法如下：
每次获取为空：SavedRequest savedRequest = this.requestCache.getRequest(request, response);
saveRequest为Null，求解，大神帮忙呀！
@Override
public void onAuthenticationSuccess(HttpServletRequest request,
HttpServletResponse response, Authentication authentication)
throws ServletException, IOException {
bindUserToSession(request);
User user = (User) request.getSession().getAttribute(
ConstValueUtil.CUR_USER);
SavedRequest savedRequest = this.requestCache.getRequest(request, response);
if (savedRequest == null) {
super.onAuthenticationSuccess(request, response, authentication);
return;
}
if (isAlwaysUseDefaultTargetUrl()
|| StringUtils.hasText(request
.getParameter(getTargetUrlParameter()))) {
this.requestCache.removeRequest(request, response);
super.onAuthenticationSuccess(request, response, authentication);
return;
}
// List<User> onlineLawyers = userService.getOnlineLawyers();
// request.getSession().setAttribute("onlineLawyers", onlineLawyers);
saveLoginHistory(user, request);
