I have implemented security very basic following the Bakery App. My Java Security Configuration looks like this now:

public class SecurityConfig extends WebSecurityConfigurerAdapter {
    protected void configure(HttpSecurity http) throws Exception {

    public void configure(WebSecurity web) throws Exception {
                "/frontend-es5/**", "/frontend-es6/**"


The application is working. But I have noticed that accessing other "routes" like "ui/mypage" using the app its opening but when i refresh the page "ui/mypage" using browser the page is being blocked as restricted which i want to happen when i click on the menu. How does vaadin enforce this configuration when making a call via route mechanism behaviour (ajax).

we added a new tutorial about Spring Security and Vaadin: https://vaadin.com/tutorials/securing-your-app-with-spring-security

Maybe, it's worth a try for you? Also, I am very interested in feedback for future improvements. One additional suggestion was to talk about the new Vaadin login component that simplifies the whole task a lot.

Cheers, Paul
