[keycloak-user] Keycloak-spring-boot-adapter CORS bug?

Before looking at the CORS stuff let's check how you have set up your
keycloak configuration ? The example you refer to is : a SpringBoot REST
service and a JS frontend, which means :
- Your REST service must be a particular keyloak client with bearer-only.
- Your frontend service must be a particular keycloak client, and your JS
app should use the keycloak.js adapter. From that client you will be
redirected to the keycloak login page, after it redirects back you have to
pass the token in the header before doing your backend call.
Regarding cors config in the properties file, these are not relevant for
the SpringBoot adapter (we need to document that or make it work ;) ) but
configuring CORS directly in SB should be enough.
Regarding your SB 1.4.1 , this has been reported and fixed, it will be
available in the next KC release.

> Hello all,
> I'm building an application with a Spring Boot (1.4.0) resource service and

> keycloak.cors = true
> keycloak.cors-max-age = 1000
> keycloak.cors-allowed-methods = POST, PUT, DELETE, GET
> These didn't give an error. (keycloak.enable-cors = true did). Still, I get
