如何在 opensaml 4.0.1 中导入 AuthnContextClassRef？

Question

我正在尝试将我的代码从旧版本的 opensaml 迁移到版本 4.0.1

AuthnContextClassRef authnCtxClassRef = null;
            
            final AuthnContext authnCtx = existing20authnStatement.getAuthnContext();

            if (authnCtx != null) {
                authnCtxClassRef = authnCtx.getAuthnContextClassRef();

                if (authnCtxClassRef != null) {
                    authnCtxClassRefName = authnCtxClassRef.getAuthnContextClassRef();

                    if (authnCtxClassRefName != null) {
                        authNStmt.setAuthenticationInstant(now);
                        authNStmt.setAuthenticationMethod(translateAuthN20to11(authnCtxClassRefName));
                        authNStmt.setSubject(makeSubject(subjectName, nameId));

                        assertion.getAuthenticationStatements().add(authNStmt);
                    }
                }
            }

我可以从源代码中看到该类定义在org.opensaml.saml.saml2.core.AuthnContextClassRef 但是当我尝试导入它时，它说

AuthnContextClassRef 无法解析为类型

类 ConfirmationMethod 也是如此，编写的代码如下：

final ConfirmationMethod confirmationMethod = buildObj(ConfirmationMethodBuilder.class,ConfirmationMethod.DEFAULT_ELEMENT_NAME);
confirmationMethod.setConfirmationMethod(SAML10_CM_SENDER_VOUCHES);

我猜你的 POM 中缺少一些依赖项。我有一个working PoC for OpenSAML 4 here。我使用以下依赖项和 AuthnContextClassRef 工作正常。

<dependency>
    <groupId>org.opensaml</groupId>
    <artifactId>opensaml-core</artifactId>
    <version>4.1.1</version>

我尝试了 4.0.1，它也可以工作
