QUESTION
I have a vaadin14 application that I want to enable different types of authentication mechanisms on different url paths. One is a test url, where authentication should use DB, and the other is the production url that uses keycloak.
I was able to get each authentication mechanism to work separately, but once I try to put both, I get unexpected results.
In both cases, I get login page, but the authentication doesn't work correctly. Here's my security configuration, what am I doing wrong?
...ANSWER
Answered 2021-Jun-06 at 08:12Navigating within a Vaadin UI will change the URL in your browser, but it will not necessarily create a browser request to that exact URL, effectively bypassing the access control defined by Spring security for that URL. As such, Vaadin is really not suited for the request URL-based security approach that Spring provides. For this issue alone you could take a look at my add-on Spring Boot Security for Vaadin which I specifically created to close the gap between Spring security and Vaadin.
But while creating two distinct Spring security contexts based on the URL is fairly easy, this - for the same reason - will not work well or at all with Vaadin. And that's something even my add-on couldn't help with.
Update: As combining both security contexts is an option for you, I can offer the following solution (using my add-on): Starting from the Keycloak example, you would have to do the following:
- Change
WebSecurityConfig
to also add your DB-basedAuthenticationProvider
. Adding yourUserDetailsService
should still be enough. Make sure to give every user a suitable role. - You have to remove this line from
application.properties
:codecamp.vaadin.security.standard-auth.enabled = false
This will re-enable the standard login without Keycloak via a Vaadin view. - Adapt the
KeycloakRouteAccessDeniedHandler
to ignore all test views that shouldn't be protected by Keycloak.
I already prepared all this in Gitlab repo and removed everything not important for the main point of this solution. See the individual commits and their diffs to also help focus in on the important bits.

I have an angular application that is converted to electron. On building the application, white screen comes but on reloading, the application runs perfectly. What can be the cause for it ? Any help will be appreciated.

QUESTION
I have security setup in my Spring Boot application using OpenId and Spring Boot Security.
By accident I forgot to add a role type to my @PreAuthorize("hasAnyRole('...)")
tag and tried to make a call as a USER
and was denied (403), but I do have the hasAnyRole stated in my securityConfig file. Once I added the role to the preAuth tag it worked, but I'm wondering if that is expected behavior? Or am I doing something wrong in the security config file?
I'm using the following Spring Boot Security Settings
...ANSWER
Answered 2021-Jun-03 at 11:10The rule in the HttpSecurity
configuration was not ignored, it was simply evaluated before the rule in @PreAuthorize
.
A call to /api/enforcementactions
from a user with the role USER
will first go through the Spring Security filter chain.
This is where the rule from HttpSecurity
will be examined.
It states that if a user has any of the following roles "ADMIN"
, "DEVELOPER"
or "USER"
then they may proceed.
The user in question has the role "USER"
so the request continues down the filter chain.
Once the request has gone through the filter chain, then the rule in @PreAuthorize
will be checked, right before the Controller method is called.
This rule states that only users with the roles "ADMIN"
and "DEVELOPER"
can access this method, and our user only has the role "USER"
so their request is rejected at this point.
It may appear that the @PreAuthorize
rule is the only one being considered, but that is because it is more specific.
If the rule in HttpSecurity
was more specific then the request would be reject in the filter chain before it reached @PreAuthorize
.
QUESTION
Helo Here, I Hope you are doing well. I's been few days I'm having this problem.
I have a spring boot API using Azure AD authentication thanks to AADResourceServerWebSecurityConfigurerAdapter
.
Here is the flow I want to have:
- User gets token from Azure in the react native frontend (done)
- User logs into the api thanks to the given token. (to-do)
- If user doesn't exists in local db, then it's created thanks to info from the token.
Here is my question: How can I do to be able to have a callback / function executed when the user first connect to the api with a new token ? With this answer, I will be able to check if an user exist with the provided email in the token, and create it if it's not existing.
Here is my websecurity config:
...ANSWER
Answered 2021-Jun-01 at 08:16As you said that you've done the step of getting access token. So I think you can add a filter to judge if the user contained in the token exists in your database. Here's a sample filter.

QUESTION
I have a springboot application where I authenticate a user and if he is logged in I redirect him to the index.html. However, this index page just loads the plain .html and no js or css at all. I don't see any error in the server error logs nor in the browser's console. I have tried disabling spring security on my css files to no effect.
Here is my project structure:
- resources
- static
- css_general
- css_page_specific
- login.html
- index.html
- commons.js
- static
Here is my application.properties config. I have pointed thymeleaf's default path to static folder so that I can at least get this running first.
...ANSWER
Answered 2021-May-13 at 16:35The reason this happens is because you are storing your templates in /static
(which lets you access those files without running them through the regular parsing and rendering processes of Thymeleaf). Accessing /index.html
returns the file as static html. In order to fix this you need to:
Create another controller (or add another method to your login controller) that serves
index.html
through the Thymeleaf renderer.

I have a Vaadin 14.0.10 app with Spring Boot and a Spring Security configuration. I'm trying to update it to 14.5.4, but after the update, I get a blank page when I try to load the app. There are no errors on the server logs, but on the browser console, it shows two errors:
...ANSWER
Answered 2021-May-07 at 06:09The problem was webpack.generated.js
, which was erroneously stored in the project's Git repository. Deleting the file and rebuilding project fixed the issue. Even though this was a "user error" in a sense, the file should have been automatically overridden in the case of a version upgrade, as the webpack output path has been changed between 14.0 and 14.5: https://github.com/vaadin/flow/issues/10932
