GOAL
To setup basic authentication in HTTP listener via spring module for an exposed soap web service which was created using APIKit for SOAP in Studio app and then test the endpoint via Soap UIPREREQUISITES
Create soap web service using APIKit for SOAP - Refer https://docs.mulesoft.com/apikit/4.x/apikit-4-soap-project-task단계
Note: Few things are changed from the steps mentioned in this article.
1a. Updated spring security to http://www.springframework.org/schema/security/spring-security-5.4.xsd" from beans.xml as it was required.
1b. For Spring framework 5.x, default password encoder changes from NoOpPasswordEncoder to BCryptPasswordEncoder, it is necessary to add prefix {noop} before password. Further documents are available at Spring Security Reference and Spring module - Mule 4
2. Include the HTTP basic authentication code before the SOAP Router
3. Test soap endpoint from soap UI.
Note: Before testing the endpoints in soap UI, Enable preemptive authentication.
preemptive authentication means that the server expects that the authorization credentials will be sent without providing the Unauthorized response. This reduces the load on network and the server itself.
Soap UI > Preferences > HTTP Settings > To enable preemptive authentication, select the Authenticate preemptively check box.
