使用 Spring SAML 从 https 加载元数据

Question

我想使用 https 协议从网络导入一些元数据：

@Bean
public HTTPMetadataProvider ssoCircleMetadataProvider()
        throws MetadataProviderException {
    String metadataURL = "https://idp.ssocircle.com/idp-meta.xml";
    final Timer backgroundTaskTimer = new Timer(true);
    HTTPMetadataProvider provider = new HTTPMetadataProvider(
            backgroundTaskTimer, httpClient(), metadataURL);
    provider.setParserPool(parserPool());
    return provider;
}

通过阅读documentation，我发现了这一步：

默认情况下，使用基于 HTTP 的提供程序加载元数据 HTTPS 执行在您的 JDK 中配置的信任验证。如果 你想在你的 keyStore 中使用证书，添加以下内容 更改 HTTP 客户端使用的 socketFactory 的 bean：

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetClass" value="org.apache.commons.httpclient.protocol.Protocol"/>
    <property name="targetMethod" value="registerProtocol"/>
    <property name="arguments">
        <list>
            <value>https</value>
            <bean class="org.apache.commons.httpclient.protocol.Protocol">
                <constructor-arg value="https"/>
                <constructor-arg>
                    <bean class="org.springframework.security.saml.trust.httpclient.TLSProtocolSocketFactory"/>
                </constructor-arg>
                <constructor-arg value="443"/>
            </bean>
        </list>
    </property>
</bean>

在Java Config中转换，变成：

@Bean
public Protocol httpClientProtocol() {
    org.springframework.security.saml.trust.httpclient.TLSProtocolSocketFactory factory =
            new org.springframework.security.saml.trust.httpclient.TLSProtocolSocketFactory();
    Protocol httpClientProtocol = new Protocol ("https", factory, 443);
    return httpClientProtocol;
}

@Bean
public MethodInvokingFactoryBean methodInvokingFactoryBean() {
    MethodInvokingFactoryBean methodInvokingFactoryBean = new MethodInvokingFactoryBean();
    methodInvokingFactoryBean.setTargetClass(Protocol.class);
    methodInvokingFactoryBean.setTargetMethod("registerProtocol");
    Object[] args = {"https", httpClientProtocol()};
    methodInvokingFactoryBean.setArguments(args);
    return methodInvokingFactoryBean;
}

但未找到 org.springframework.security.saml.trust.httpclient.TLSProtocolSocketFactory 类结果。我正在使用 Spring SAML 的 1.0.0-RC2 版本。

我做错了吗？

如何修复此错误并根据需要加载元数据？

更新

通过使用 SNAPSHOT 存储库，我可以使用 TLSProtocolSocketFactory 类。 我已将 SSOCircle 的证书导入到我的密钥库中，但尽管如此，应用程序仍返回如下错误：

[2014-07-31 17:33:27.596] boot - 11800 ERROR [localhost-startStop-1] --- HTTPMetadataProvider:    Error retrieving metadata from https://idp.ssocircle.com/idp-meta.xml
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

更新 2

我已根据您的建议修复了我的代码。我已将所有证书导入密钥库，但在启动时应用程序返回此错误：

请注意，使用的证书是由 GoDaddy 验证的。

Answer 1

TLSProtocolSocketFactory 类仅在主干中可用，并将成为 1.0.0.FINAL 的一部分。 RC2 中唯一的选择是将密钥添加到 JDK 的密钥库中。

更新：

此存储库中提供了 Spring SAML 的快照版本：

<repository>
  <releases>
    <enabled>false</enabled>
  </releases>
  <snapshots>
    <enabled>true</enabled>
  </snapshots>
  <id>com.springsource.repository.maven.snapshot</id>
  <name>SpringSource Enterprise Bundle Maven Repository - SpringSource Snapshot Releases</name>
  <url>http://maven.springframework.org/snapshot</url>
</repository>

您可能想阅读“新增功能”一章，其中列出了自 RC2 以来的更改，其中一些涉及向后兼容性。

另一个更新：

你的初始化错误，TLSFactory需要作为bean启动，你可能还需要MetadataManager中的依赖。

@Bean
public ProtocolSocketFactory socketFactory() {
    return new TLSProtocolSocketFactory();
}

@Bean
public Protocol socketFactoryProtocol() {
    return new Protocol("https", socketFactory(), 443);
}

@Bean
public MethodInvokingFactoryBean socketFactoryInitialization() {
    MethodInvokingFactoryBean methodInvokingFactoryBean = new MethodInvokingFactoryBean();
    methodInvokingFactoryBean.setTargetClass(Protocol.class);
    methodInvokingFactoryBean.setTargetMethod("registerProtocol");
    Object[] args = {"https", socketFactoryProtocol()};
    methodInvokingFactoryBean.setArguments(args);
    return methodInvokingFactoryBean;
}

@Bean
@Qualifier("metadata")
@DependsOn("socketFactoryInitialization")
public CachingMetadataManager metadata() throws MetadataProviderException, IOException     {
  ...
}
