When I configure RestTemplate use HttpClient then my interceptor only execute for first time, in second time it'll hang up when execute, in this block below. Traditionally, developers have relied on RestTemplate for this purpose. Learn how to build a gen AI RAG application with Spring AI and the MongoDB vector database through a practical example: >> Building a RAG App Using MongoDB and Spring AI Mocking is an essential part of unit testing TestRestTemplate can work as a wrapper for RestTemplate, e. it accepts 2 query params fieldList and systemId along with Authorization Token(Bearer) Ba OAuth 2.

Open the app. The interface contains the method intercept, which Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company This feels so wrong, because passing through authentication tokens is a cross-cutting concern. I just tried to avoid asking user for providing the password and user name for ouath so I hard coded it in the source just for that purpose. it accepts 2 query params fieldList and systemId along with Authorization Token(Bearer) Ba @webgeek - It is just an example so trying to make it as condensed as possible I hard coded some stuff that's why it still worked.

The Example Application. 1. This figure shows a typical use case of JWT authentication. @Bean public OAuth2RestOperations restTemplate(){ AccessTokenRequest accessTokenRequest = new DefaultAccessTokenRequest(); OAuth2ClientContext The KeycloakRestTemplate works when your micro-service was initially called by a logged in user, then from there you can make calls to other protected micro-services. Example: @Slf4j @Component @AllArgsConstructor(onConstructor = @__(@Autowired)) public class JwtRequestFilter extends OncePerRequestFilter { private JwtUtil jwtUtil; private LoginService login; @Override protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws ServletException 1: By placing @ClientQueryParam on the interface, we ensure that my-param will be added to all requests of the client.
