There is a specific issue with Spring Security and Spring WebFlux's WebClient in general, where it is not that easy to understand how to pass the authentication from the Spring Framework MVC controller directly into WebClient, if the project does not use OAuth2Authentication, and when the Spring Security is configured so that the endpoints must require authority (ROLE_ etc. Returns the enum constant of this type with the specified name.

Now, on the application page, click on Generate a new client secret. After implementing a request filter, we have to "attach" it to the WebClient instance. This way of setting up Basic auth was only available while creating WebClient since it relies on WebClient filters. Using ExchangeFilterFunctions. This guide assumes that you chose Java.

The following example configures a 60 second read timeout and adds a ReadTimeoutHandler: Simply put: WebClient client = new WebClient() client.Proxy.Credentials = CredentialCache . Hopefully the example code included should be easy enough to understand. As demonstrated previously, when we configured a .
