Question

我使用此示例： https://github.com/foo4u/keycloak-spring-demo

我的WEB-INF文件夹中有keycloak.json文件，但是当我运行我的应用程序时，我得到了这个例外：

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

此例外的完整堆栈：

这段代码只是Spring boot和Keycloak之间集成的一个例子。

你能告诉我我做错了什么吗？

感谢您的回答和时间。

Answer 1

尽管这是一个很好且有效的例子，可以追溯到2015年。我相信它使用的是完全过时的Keycloak 1.2.0。 Spring here有一组示例。他们中的大多数都是最新的变化。

我建议您查看这些示例并阅读docs。

Answer 2

如果您使用带有spring boot 2或spring boot 1.5的keycloak适配器，则必须在application.properties或application.yaml文件中提及以下属性

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

如果仍然出现错误，请发布错误，我将分享代码:)
