用戶登錄超過必定時間,在頁面作請求時,提示相似登錄已超時,請從新登錄信息。web
實現:ajax
1.超時時間配置(web.xml):spring
<session-config>
<!-- 10分鐘 --> <session-timeout>10</session-timeout> <tracking-mode>COOKIE</tracking-mode> <cookie-config> <secure>false</secure> <http-only>true</http-only> </cookie-config>
</session-config>
2.session超時過濾、ajax請求處理(spring-security.xml)json
<!-- invalidSession.htm 是一個不存在的頁面 --> <session-management invalid-session-url="/invalidSession.htm" session-fixation-protection="newSession"> <concurrency-control session-registry-ref="sessionRegistry" max-sessions="1" error-if-maximum-exceeded="true" /> </session-management> <beans:bean id="sessionRegistry" class="org.springframework.security.core.session.SessionRegistryImpl" /> <!-- 未登陸的切入點 --> <beans:bean id="authenticationProcessingFilterEntryPoint" class="com.xxx.xxx.web.controller.auth.MyLoginUrlAuthenticationEntryPoint"> <beans:property name="loginFormUrl" value="/login.htm"></beans:property> </beans:bean>
3.繼承LoginUrlAuthenticationEntryPoint (MyLoginUrlAuthenticationEntryPoint.java)cookie
public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException, ServletException { // 若是是ajax請求 if (RequestUtil.isAjaxRequest(request)) { String key = ErrorCodes.BUSINESS_EXCEPTION_PREFIX + ErrorCodes.INVALID_SESSION; Object[] args = new String[0]; String message = messageSource.getMessage(key, args, key, LocaleContextHolder.getLocale()); String jsonObject = "{\"message\":\"" + message + "\"," + "\"needlogin\":true,\"cause\":\"Access is denied\"}"; ResponseUtil.writeJson(response, jsonObject); return; } else { super.commence(request, response, authException); } }
4.js 擴展ajaxsession
success:function(data, textStatus){ //成功回調方法加強處理 if (data.denied) { wms.frame.notifyWarning(data.message); } else if (data.needlogin) { wms.frame.notifyWarning(data.message); } else{ fn.success(data, textStatus); } }
