java - 使用 Spring SAML 从 https 加载元数据

Question

我想使用 https 协议(protocol)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:

By default loading of metadata using the HTTP-based provider over HTTPS performs trust verification configured in your JDK. In case you'd like to use certificates in your keyStore, add the following bean which changes the socketFactory used by the HTTP Client:

<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;
}

但是 org.springframework.security.saml.trust.httpclient.TLSProtocolSocketFactory 类结果没有找到。我使用的是 Spring SAML 的 1.0.0-RC2 版本。

我做错了什么吗？

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，我能够使用 TLSProtocolSocketFactory 类。我已经将 SSOCircle 的证书导入到我的 keystore 中，但尽管如此，应用程序还是返回了如下错误:

[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

我已经根据您的建议修改了我的代码。我已将所有证书导入 keystore ，但在启动时应用程序返回此错误:

请注意，使用的证书由 GoDaddy 验证。

TLSProtocolSocketFactory 类仅在主干中可用，并且将成为 1.0.0.FINAL 的一部分。 RC2 中唯一的选择是将 key 添加到 JDK 的 keystore 。

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:

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

@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     {
  ...
}
