[Andreea Ciuprina]

This works, thank you very much for your help! :)



And yes, a bit more documentation would be nice.



Best, 

Andreea

Hi,
Yes sorry, I replied yesterday without double checking the code, this should work :
 
keycloak.securityConstraints[0].securityCollections[0].methods[0] = GET

I will create a ticket to improve the documentation for this.

Hi Sebasien, 



Thank you for your answer.

After adding your suggestion to the security constrainst, I get the following error:



Error creating bean with name 'keycloak-org.keycloak.adapters.springboot.KeycloakSpringBootProperties': Could not bind properties to KeycloakSpringBootProperties (prefix=keycloak, ignoreInvalidFields=false, ignoreUnknownFields=false, ignoreNestedProperties=false); nested exception is org.springframework.boot.bind.RelaxedBindingNotWritablePropertyException: Failed to bind 'keycloak.securityConstraints[0].securityCollections[0].http-method' from 'applicationConfig: [classpath:/application.properties]' to 'securityConstraints[0].securityCollections[0].http-method' property on 'org.keycloak.adapters.springboot.KeycloakSpringBootProperties$SecurityConstraint'



My configuration looks like this:





keycloak.securityConstraints[0].securityCollections[0].name = secured end points
keycloak.securityConstraints[0].securityCollections[0].authRoles[0] = admin
keycloak.securityConstraints[0].securityCollections[0].authRoles[1] = user
keycloak.securityConstraints[0].securityCollections[0].patterns[0] = /api/v1/hello/*
keycloak.securityConstraints[0].securityCollections[0].http-method = GET

Do you know what could the problem be?



Thank you!

Best, 

Andreea

You can add the configuration about the policy enforcer in your application.properties, just one difference with the keycloak.json is that you must write "policy-enforcer-config" (instead
 of just policy-enforcer).

Regarding HTTP Verb authz , it *should* work since Spring Boot Adapter just passes along the configuration to the underlying Servlet Container (Tomcat, undertow or Jetty).

But even without using the authorization layer, you should be able to achieve this by configuring the security constraints. 

keycloak.securityConstraints[1].securityCollections[0].http-method = GET
 etc ...

Hello!
 
 
 
 We are building an online application for which we are using Keycloak for authentification and authorization, connected
 
 to our Spring Boot backend using the Spring Boot adapter.
 
 
 We would like to achive more fine-grained authorization, more specifically, we would like to set-up HTTP verb based 
 
 authorization, for example, allow only GET requests for some end-points, GET and POST for others, only POST for other end-points etc.
 
 
 
 I am aware of the Policy Enforcer adapter, but I could not find any specific documentation regarding how to use that with Spring Boot, where there is 
 
 not keycloak.json file used for configuration.
 
 
 
 Therefore, my questions are:
 
 1. Can HTTP verb based authorization be achieved using the Spring Boot adapter? 
 
 2. If the answer to question 1 is yes, then could you please provide a minimal configuration example?
 
 
 
 Thank you!
 
 Best regards, 
 
 Andreea
