Question

我正在使用这个例子：https://github.com/foo4u/keycloak-spring-demo

我的WEB文件夹中有keycloak.json文件，但是当我运行我的应用程序时，我得到了以下异常：

java.lang.RuntimeException: Must set 'realm' in config

此异常的完整堆栈：

这段代码只是Spring和Keycloak集成的一个例子。

你能告诉我我做错了什么吗？

谢谢你的回答和时间。

Answer 1

尽管这是一个很好的例子，但这要追溯到2015年。我相信它使用了完全过时的Keycloak 1.2.0。Spring 这里有一组示例。其中大多数都是最新变化的。

我建议看看这些例子，并阅读文档。

Answer 2

如果您使用的是带有spring 2或spring 1.5的keycloak适配器，则必须在application.properties或application.yaml文件中提到以下属性

keycloak.auth-server-url=http://localhost:8180/auth
keycloak.realm=abc
keycloak.resource=movie-app
keycloak.public-client=false
keycloak.principal-attribute=preferred_username

如果它仍然给出错误，请发布错误，我将共享代码:)
