出站连接的 SSL 配置在 websphere-liberty 17.0.0.2 中不起作用

Question

我正在尝试将 websphere-liberty 服务器配置为对所有出站连接(实际上是 REST 调用)使用默认 keystore 和信任库，并为入站使用自定义 key 和信任库。但是当尝试调用外部 REST 服务时，它会因 SSLHandshakeException 而失败。在日志中我可以看到它使用我的自定义信任库而不是默认信任库。
下面是我的 server.xml

<?xml version="1.0" encoding="UTF-8"?>
<server description="Default server">
    <featureManager>
        <feature>appSecurity-2.0</feature>
        <feature>transportSecurity-1.0</feature>
        <feature>jaxrs-2.0</feature>
        <feature>json-1.0</feature>
        <feature>javaMail-1.5</feature>
        <!--<feature>ssl-1.0</feature>-->
    </featureManager>

    <sslDefault sslRef="saasSSLConfig" outboundSSLRef="outboundSSLConfig" />

    <ssl id="saasSSLConfig" keyStoreRef="saasKeyStore" trustStoreRef="saasTrustStore" clientAuthentication="true" sslProtocol="TLSv1" />
    <keyStore id="saasKeyStore" location="/opt/ibm/wlp/output/defaultServer/resources/security/sbs_endpoint_keystore.jks" password="pwd" />
    <keyStore id="saasTrustStore" location="/opt/ibm/wlp/output/defaultServer/resources/security/serverTruststore.jks" password="pwd" />

    <ssl id="outboundSSLConfig" keyStoreRef="defaultKeyStore" trustStoreRef="defaultTrustStore" />

    <basicRegistry id="basic" realm="BasicRealm">
        <!-- <user name="yourUserName" password="" />  -->
    </basicRegistry>

    <httpEndpoint id="defaultHttpEndpoint" host="*" httpPort="9080" httpsPort="9443" />
    <applicationManager autoExpand="true"/>
</server>

顺便说一句，如果将 saasSSLConfig 更改为使用 defaultTrustStore 而不是 saasTrustStore，那么一切正常。

服务器版本:

WebSphere Application Server 17.0.0.2 (1.0.17.cl170220170523-1818) on IBM J9 VM, version pxa6480sr4fp7-20170627_02 (SR4 FP7) (en_US)

错误:

[ERROR] CWPKI0022E: SSL HANDSHAKE FAILURE:  A signer with SubjectDN CN=*.api.ibm.com, O=International Business Machines, L=Armonk, ST=New York, C=US was sent from the target host.  The signer might need to be added to local trust store /opt/ibm/wlp/output/defaultServer/resources/security/serverTruststore.jks, located in SSL configuration alias saasSSLConfig.  The extended error message from the SSL handshake exception is: PKIX path building failed: java.security.cert.CertPathBuilderException: PKIXCertPathBuilderImpl could not build a valid CertPath.;

Answer 1

Liberty 不会自动加载证书。如果需要，您可以创建一个 keyStore 元素来指向它。所以在你上面的例子中，你可以创建这样的配置。

<ssl id="outboundSSLConfig" keyStoreRef="cacertKeyStore" />
<keyStore id="cacertKeyStore" location=<fill in path to your jdk cacerts file> password="changeit" />

我假设您不需要此配置的 key ，因此我在 outboundSSLConfig 上简化为仅一个 keyStoreRef。它将使用 keyStoreRef 指向的 key 和信任。
