我正在使用Spring boot 2.1.7 Release和Keycloak-spring-boot-2-starter：4.0.0.Final version。 此 keycloak-spring-boot-2-starter 会自动下载与 4.0.0.keycloak 适配器依赖项的最终版本对应的所需密钥 capoak 适配器依赖项。 现在，当我调用受密钥斗篷保护的资源(需要由密钥斗篷服务器授权的其余 api(时，我收到以下错误：-

当我从keycloak-authz-client-4.0.0.Final.jar jar中反编译ServerConfiguration.class时，我可以看到没有"introspection_endpoint"这样的属性，这就是为什么应用程序抛出"无法识别的字段"introspection_endpoint"的错误。
当我查看相对较低的keycloak-authz-client版本时，即keycloak-authz-client-3.3.0.Final.jar，我可以看到"introspection_endpoint"属性存在。因此，此属性似乎被丢弃在较高版本中的某个地方，例如keycloak-authz-client-4.0.0.Final.jar，keycloak-authz-client-4.0.0.Beta2.jar.etc。
因此，我想使用钥匙斗篷-弹簧-启动器而不是钥匙斗篷-弹簧-靴-2-，并注入相应版本的钥匙斗篷适配器BOM。我手动包含以下依赖项：-
compile "org.keycloak:keycloak-spring-boot-starter:3.3.0.Final"
compile "org.keycloak:keycloak-spring-boot-adapter:3.3.0.Final"
compile "org.keycloak:keycloak-authz-client:3.3.0.Final"
compile "org.keycloak:keycloak-spring-security-adapter:3.3.0.Final"
compile "org.keycloak:keycloak-spring-boot-adapter:3.3.0.Final"

compile "org.keycloak:keycloak-adapter-core:3.3.0.Final"
compile "org.keycloak:keycloak-common:3.3.0.Final"
但是现在当我尝试运行 spring 启动应用程序时，它会退出并显示以下错误：-

Note:- It appears that the spring boot version and keycloak adapter are not compatible to each other.
Has anyone faced this issue before?
One solution/workaround that I can think off is to edit the ServerConfiguration.class of keycloak-authz-client-4.0.0.Final.jar and add the "introspection_endpoint".
Request you to please advise if anyone has faced a similar issue.
我正在使用以下版本：- 甲骨文 JDK - 1.8 弹簧引导 - 2.1.7.发布 弹簧云依赖：格林威治.SR2 钥匙斗篷 - 7.0.0
谢谢
我认为你的问题出在依赖项声明中，正如你在keycloak文档中看到的那样，你使用的liobrary是org.keycloak：keycloak-spring-boot-starter。该软件包包括使用keycloak所需的所有内容，还包括授权令牌所需的keycloak-authz-client。如果包含此库，则将删除上面添加的所有依赖项：
compile "org.keycloak:keycloak-spring-boot-starter:3.3.0.Final"
compile "org.keycloak:keycloak-spring-boot-adapter:3.3.0.Final"
compile "org.keycloak:keycloak-authz-client:3.3.0.Final"
compile "org.keycloak:keycloak-spring-security-adapter:3.3.0.Final"
compile "org.keycloak:keycloak-spring-boot-adapter:3.3.0.Final"

compile "org.keycloak:keycloak-adapter-core:3.3.0.Final"
compile "org.keycloak:keycloak-common:3.3.0.Final"
2022 年更新
不再支持钥匙斗篷适配器：https://www.keycloak.org/2022/02/adapter-deprecation.html
我在那里详细介绍了弹簧引导 3 的替代方案： 将钥匙斗篷弹簧适配器与弹簧靴 3
一起使用
