用户注销功能：

logout注释：

.logout().deleteCookies("remove").invalidateHttpSession(false)

.logoutUrl("/custom-logout").logoutSuccessUrl("/logout-success");

默认访问地址是：/logout:     logoutUrl("/logout");如果是默认的话，会清除session和cookie里边的相关东西

LogoutSuccessHandler()方法的源码:

public interface LogoutSuccessHandler {

void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response,

Authentication authentication) throws IOException, ServletException;

}
