登录后（将用户重定向到哪个url）发生什么情况，由处理AuthenticationSuccessHandler。
该接口（实现它的具体类SavedRequestAwareAuthenticationSuccessHandler）由方法中的AbstractAuthenticationProcessingFilter或子类之一（UsernamePasswordAuthenticationFilter）调用successfulAuthentication。
因此，为了在情况3中进行其他重定向，你必须继承子类SavedRequestAwareAuthenticationSuccessHandler并使其执行你想要的操作。
有时（取决于你的确切用例）足以启用由（的的超类）调用其useReferer标志。AbstractAuthenticationTargetUrlRequestHandlerSimpleUrlAuthenticationSuccessHandlerSavedRequestAwareAuthenticationSuccessHandler
