I am currently developing an application with spring boot with keycloak for the maintenance of user access. I followed this guide link and the keycloak documentation to deploy my application in tomcat, but the same documentation suggests not using the spring boot adapter if you want to deploy the application as WAR.
Why is it suggested not to use it?
So far I have used the adapter and I have also made the necessary changes to use XML configuration (the one that suggests the documentation) and I have not been able to notice any difference
Here is the keycloak documentation: link
