如何解决消息：意外元素“{urn:jboss:domain:keycloak:1.1}subsystem”
我正在尝试在我的应用中使用 keycloak。我在 docker 上运行 keycloak 并使用 wildfly 20 作为应用程序服务器。我用这个 scrypt 来启动 keycloak。
version: '3'
services:
keycloak:
image: quay.io/keycloak/keycloak:10.0.1
container_name: keycloak
environment:
DB_VENDOR: postgres
DB_ADDR: host.docker.internal
DB_USER: keycloak
DB_PASSWORD: test
KEYCLOAK_USER: admin
KEYCLOAK_PASSWORD: test
ports:
- 8079:8080
- 8443:8443
然后我将此代码段添加到我的 standalone.xml
<subsystem xmlns="urn:jboss:domain:keycloak:1.1">
<secure-deployment name="pato-ejb.war">
<realm>pato</realm>
<auth-server-url>http://localhost:8079/auth</auth-server-url>
<ssl-required>external</ssl-required>
<resource>pato</resource>
<credential name="secret">password</credential>
</secure-deployment>
</subsystem>
和我的 web.xml 的安全设置
<security-constraint>
<web-resource-collection>
<web-resource-name></web-resource-name>
<description>Protects all resources</description>
<url-pattern>*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>
<security-role>
<role-name>admin</role-name>
</security-role>
<login-config>
<auth-method>KEYCLOAK</auth-method>
<realm-name>pato</realm-name>
</login-config>
<security-constraint>
<web-resource-collection>
<web-resource-name>user/</web-resource-name>
<url-pattern>/user/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>user</role-name>
</auth-constraint>
</security-constraint>
<security-role>
<role-name>user</role-name>
</security-role>
最后我给 jboss 添加了 keycloak jars folder with jars
当我启动 standalone.bat 时，我立即收到此错误
11:41:14,220 ERROR [org.jboss.as.controller] (Controller Boot Thread)

解决方法
在 Keycloak Downloads 中，您会看到“客户端适配器”部分。这是您解压到 Wildfly 目录中的 .zip 或 .tar.gz 文件。虽然您拥有所需的 .jar 文件，但您缺少所有 module.xml 文件。打开当前版本，你会看到你需要的文件。此外，还有一些安装文件会更改您的 standalone.xml 以启用 Keycloak。当前层次结构类似于：

我鼓励您在 Docker 之外的本地环境中安装 Keycloak，以了解这一切是如何组合在一起的。 These steps 会引导您完成整个过程，但基本上您将文件解压缩到 Wildfly 主目录并在 bin 目录中运行相应的脚本。
