spring - 如何将 Keycloak 与 Spring 集成（无引导）？

Question

几天来，我一直试图让我的 Spring Web 应用程序与 Keycloak 一起工作，但没有任何运气。我按照此处文档中提到的说明进行操作。

我已经设置了一个在 Wildfly 9 中运行的 Keycloak 服务器。对于我的 Web 应用程序，我使用 JBoss AS 7 和 Spring Framework 4.1.7。我已经按照此处的步骤为我的 JBoss AS 7 配置了适配器。然后对于我的 Spring Web 应用程序，我按照此处提到的步骤进行操作。但是，当我尝试运行我的应用程序时，它不会重定向到我的 Keycloak 服务器。它只显示页面而不需要任何身份验证。

请在下面查看我的代码。

在将级别设置为 JBoss Standalone 中的 DEBUG 并在我的应用程序的 log4j.xml 中添加记录器后，我从应用程序服务器（JBoss AS 7）日志文件中得到了这个。它有点长，无法在这里粘贴，所以我把它粘贴在这里。希望它有所帮助。

2015 年 8 月 26 日更新

我尝试了另一种方法，即使用安全约束设置 web.xml 文件并删除 pom.xml 文件中的 spring 安全适配器引用，并改用 keycloak 核心和 keycloak 适配器核心。它现在重定向到我的 Keycloak 服务器。但是，当我使用用户名和密码登录时，我被重定向回 web url，但它返回一个错误，Http Status 403 Access to the specified resource () has been denied. 我不确定我做错了什么。

Keycloak 服务器配置：

境界：derealm

客户端设置：

• 客户：演示
• 客户端协议：openid-connect
• 访问类型：机密
• 有效的重定向网址：http://localhost:8080/ *
• 基本网址：http://localhost:8080

客户范围：

• 允许的全部范围：TRUE

仍然没有运气。感谢任何帮助。
