java - Spring saml 演示构建问题

Question

我们公司正计划迁移到使用 SAML 进行身份验证，因此我正在使用示例演示来完成本教程，以了解如何使用 spring 框架和 Okta 实现 saml。我正在按照教程(此处:https://www.youtube.com/watch?v=JBtyGfrz-jA)进行操作，但是当我到达实现 SecurityConfiguration 的部分(视频的 ~5:09)时，它会抛出代码错误:

import static org.springframework.security.extensions.saml2.config.SAMLConfigurer.saml;

当我尝试构建它抛出的项目时:

com/example/SecurityConfiguration.java:[3,67] package org.springframework.security.extensions.saml2.config does not exist
com/example/SecurityConfiguration.java:[3,1] static import only from classes and interfaces
com/example/SecurityConfiguration.java:[39,20] cannot find symbol

我认为问题在于 maven 导入了错误的 jar 文件，但我尝试了许多不同版本的 org.springframework.security.extensions，但没有一个允许 SecurityConfiguration.java 找到 saml() 方法。

这是 pom.xml 文件:

Answer 1

当将 spring-security-saml-dsl(注意:不是 spring-security-saml2-core)从 1.0.2.RELEASE 移动到 1.0.3.RELEASE 时，Spring 搞砸了他们的项目文件。

将 spring-security-saml-dsl 的版本更改为 1.0.2.RELEASE 后应该可以解决此问题。
