Resttemplate bearer token interceptor java Using the default ClientHttpRequestFactory implementation - which is the SimpleClientHttpRequestFactory - the default behaviour is to follow the URL of the location header (for responses with status codes 3xx) - but only if the initial request was a GETrequest. The interface contains the method intercept, which You can of course annotate the method with a Header annotation and have an extra token parameter for every call your client provides, but that is not really an elegant solution as the caller needs to have access to the API key. Currently, the best approach to handle authentication is to use the new Authenticator API, designed specifically The RestTemplate below will automatically login to Keycloak with a Keycloak Service Account and renew the bearer token when necessary: RestTemplate rt = new The POST method should be sent along the HTTP request object. In this RestTemplate basic authentication tutorial, we are using In the /api/** resources there is an incoming token, but because you are using JWT the resource server can authenticate without calling out to the auth server, so there is no OAuth2RestTemplate just sitting around waiting for you to re-use the context in the token relay (if you were using UserInfoTokenServices there would be one). – Assuming you only want to test the interception and you already have set up mockito: @Test @DisplayName("Should add correct header to authorization") void There are many a tutorials on how to use the RestTemplate, this tutorial will focus on a nuanced aspect of RestTemplate which is the OAuth2RestTemplate. # Reading the Bearer Token from a Custom Header For example, you may have a need to read the bearer token from a custom header. Dependencies OAuth2RestTemplate should be used instead of RestTemplate when JWT authentication is required. Improve this question.

While the core focus of this article wasn’t Spring Boot or Spring Security, using those two technologies made it easy to demonstrate all the features discussed in this article. I think, there might be a race condition. Implementations can be registered with RestClient or RestTemplate to modify the outgoing request and/or the incoming response. The Principal in the client app requests correctly shows all authorities filled by the authorization server. A way you might avoid this is to skip executing the interceptor if you are calling the carrier gateway token url (using an if-statement), or use a different restTemplate instance without the interceptor.
