在开发spring启动应用程序时，我们使用keycloak。当使用vscode中嵌入的tomcat启动它时，一切都正常工作。
在部署时，我们想把它放在一个独立的tomcat服务器上，所以我们复制了war文件，应用程序就启动了。我们得到一个重定向到keycloak服务器，完成登录后，重定向回页面工作正常。
在加载页面时，我们得到以下错误:

这是我们当前的keycloak。json文件:
{
"realm": "realmname",
"auth-server-url": "https://ourkeycloakserver.com/auth/",
"ssl-required": "none",
"resource": "clientname",
"verify-token-audience": true,
"credentials": {
"secret": "secret"
},
"use-resource-role-mappings": true,
"confidential-port": 0,
"policy-enforcer": {}
}
知道我们应该看什么吗?keycloak配置在我们的应用程序中。
我和你有同样的问题。我发现我使用tomcat keycloak适配器，但我也在pom.xml中导入springboot-keycloak适配器，我在我的pom.xml中删除了这个，再次包和deploy.my程序工作正常…也许你可以去看看。
org.keycloak.adapters.authorization.cip。ClaimsInformationPointProviderFactory不是子类型
这意味着类ClaimsInformationPointProviderFactory在tomcat和应用程序中以不同的方式加载/冲突。解决方案是检查tomcat/lib中的jar并删除它并重新启动服务器
