好吧,在网上搜索了几天的答案后 - 我明白了。
我查看了Keycloak-spring-security-adapter的代码,找到了。
首先,我得到了用于调试的 keycloak 的日志记录杆:
logging.level.org.keycloak=DEBUG
然后我尝试使用错误令牌访问我的端点(我预计这会产生异常,即更可见的跟踪;它确实做到了):

.....
从那时起,很明显令牌正在被验证,如果您查看参与的类,您会发现它在某些情况下正在根据公钥进行验证。
在我的情况下 (bearer-only) 参与此身份验证和验证的类是:
org.keycloak.adapters.springsecurity.filter.KeycloakAuthenticationProcessingFilter
org.keycloak.adapters.BearerTokenRequestAuthenticator
希望这可以帮助像我这样的其他人在 Keycloak 中找到自己的方式。
