前文说当http://192.168.19.277:6001/authentication/loginPage路径登录后没有成功后的转跳地址 所以会报错 以下代码可以解决
解决方案
在登录成功后 前文我们配置CustomAuthenticationSuccessHandler 返回json 这个类调用了onAuthenticationSuccess 那就重写onAuthenticationSuccess方法
@Component("customAuthenticationSuccessHandler") public class CustomAuthenticationSuccessHandler extends CustomSavedRequestAwareAuthenticationSuccessHandler { @Autowired Utils utils; @Override public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException { SimpleDateFormat sd = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); SysUser sysUser = (SysUser)authentication.getPrincipal(); logger.info("|" + "用户" + sysUser.getUsername() + "于" + sd.format(new Date()) + "通过web端登录系统，ip为" + utils.getIpAddr() + "。" + "|" + sd.format(new Date()) + "|" + sysUser.getUsername()); super.onAuthenticationSuccess(request, response, authentication); } }
重写onAuthenticationSuccess 大致意思就是 在登录成功后获取转跳地址 如果没有 我们指定给他一个固定地址 这里我们指定了百度
public class CustomSavedRequestAwareAuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler { protected final Log logger = LogFactory.getLog(this.getClass()); private RequestCache requestCache = new HttpSessionRequestCache(); public CustomSavedRequestAwareAuthenticationSuccessHandler() {} @Override public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws ServletException, IOException { // 获取code码路径 现在有两种判断 // 1.如果查询缓存有 定向到缓存 也就是数据库配置 // 2.如果前台已经登录 但是退回导致session丢失 跳转可道云页面 String targetUrl; // 获取缓存 SavedRequest savedRequest = this.requestCache.getRequest(request, response); if (savedRequest == null) { // 跳转可道云 targetUrl = "https://www.baidu.com"; } else { // 跳转缓存 targetUrl = savedRequest.getRedirectUrl(); } String targetUrlParameter = this.getTargetUrlParameter(); if (!this.isAlwaysUseDefaultTargetUrl() && (targetUrlParameter == null || !StringUtils.hasText(request.getParameter(targetUrlParameter)))) { this.clearAuthenticationAttributes(request); this.logger.debug("Redirecting to DefaultSavedRequest Url: " + targetUrl); this.getRedirectStrategy().sendRedirect(request, response, targetUrl); } else { this.requestCache.removeRequest(request, response); super.onAuthenticationSuccess(request, response, authentication); } } public void setRequestCache(RequestCache requestCache) { this.requestCache = requestCache; } }
