Spring Cloud Tutorial - Spring Cloud Gateway Filters Example
The documentation on this isn't very good at the moment. I was only able to figure this out by looking at the source code for spring-cloud-gateway on github.
I think there are some changes in Spring Cloud Gateway 2. Learn more. How to Specify custom filter in application. Asked 2 years, 3 months ago. Active 2 months ago. Viewed 7k times. Also paste the filter code. GrinishNepal filter code is attached, problem is that how to specify this filter in application. Why is this -1? I am trying to figure out the same thing, there is no documentation on how to add a custom filter to a route.

It is good for development purpose, and it is used frequently in development phase, but it is not recommended in a production environment. In the Spring Security OAuth based solution, the content of access token can be a signed JWT token or an opaque value, and we have to follow the standard OAuth2 authorization flow to obtain access token.
But for those applications owned by the resource owner and there is no plan to expose these APIs to third party applications, a simple JWT token based authorization is more simple and reasonable we do not need manage the credentials of third party client applications. Spring Security itself does not provide such an option, fortunately it is not difficult to implement it by weaving our custom filter into the Spring Security Filter Chain.
In this post, we will create such a custom JWT authentication solution. In this sample application, the custom JWT token based authentication flow can be designated as the following steps. The quickest way to create a new Spring Boot project is using Spring Initializr to generate the base codes. Waiting for a while for downloading the generated codes, when it is done, extract the zip file into your local system.OAuth 2.0 and OpenID Connect (in plain English)
It is simple and stupid. We defined a VehicleNotFoundException which will be thrown if the vehicle is not found by id. Create a CommandLineRunner bean to initialize some vehicles data at the application startup stage. Run the application via executing command line mvn spring-boot:run in your terminal or running Application class in IDE directly.
The CustomUserDetailsService is trying to fetch user data by username from database. When the current user is authenticated, AuthenticationPrincipal will bind to the current principal.

Is there any timeline for implementation of this enhancement? ExchangeFilterFunction and. GatewayFilter are pretty dramatically different even though their doing something trivially similar. Thanks for advice! I am also looking forward to the implementation of the access token refreshment in the class TokenRelayGatewayFilterFactory. That way it's easier to pick up going forward.
Take a look at this comment for further details. Thanks tschlegel! That seems to work here; Also meant I could drop the dependency on spring-cloud-securitywhich kind of makes me wonder of this filter should be included here, or part of spring-cloud-gateway or spring-security itself.
I'm getting below error when I tried to integrate the given custom token relay filter in my sample cloud gateway. Could you guys please help.

Parameter 0 of constructor in gateway. Consider defining a bean of type 'org. Thank you very much tschlegel for the hint. I have upgraded it to 2.
When I tried to replicate the Websession using 2 instances of Cloud Gateway, the TokenRelayGatewayFilterFactory is not forwarding the token in the replicated instance since it is missing in the SecurityContext. Eventhough the replicated Websession has OAuth2AuthenticationToken in the SecurityContext, it don't have the access token and refresh token. Thanks for the input tschlegel but I seem to be missing a configuration to allow your relay to work.
I can confirm that the refresh functionality works with tschlegel solution Nov 21, comment. Thank you!! I've not been able to get it to work as we dont use authorisation code flow and it always seems to try that even though i remove the auth code enabling.
The tschlegel solution Nov 21, comment works for me after removing the spring-cloud-starter-security dependency. Thanks aks8m! Skip to content.

It can be summarised by the diagram below:. The JWT is then added to the header for the request forwarded to the downstream service. Now my question is quite specific to Zuul and its filters. If authentication fails in the API gateway for any reason, how can I can stop the routing and respond directly with a without continuing the filter chain and forwarding the call? At the moment if authentication fails the filter won't add the JWT to the header and the will come from the downstream service.
I was hoping my gateway could prevent this unnecessary call. I tried to see how I could use com. RequestContext to do this but the documentation is quite poor and I couldn't find a way.
You could try setting setSendZuulResponse false in the current context. This should not route the request. You could also call removeRouteHost from the context, which would achieve the same. You could use setResponseStatusCode to set the status code. I know I am very late to answer You can approach with prefilter of zuul.

Why aren't you using Spring Cloud Security for this? Deinum May 12 '16 at Deinum I didn't think I could have enough control to implement this specific design. I need to have access token outside my secured network and JWT inside. I don't have much experience with Spring Cloud security. Do you think I could use it to achieve my design? Spring Cloud Security only relays the same token to the down stream services.
