Apache CXF SOAP 客户端，使用 https 中生成的存根

Question

我正在为 SOAP Web 服务生成 SOAP 客户端。我创建了 Java 存根，当我尝试执行时出现错误：

Caused by: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException:` 

我尝试运行 InstallCert，但即使在那之后它也不起作用。

Answer 1

埋藏在堆栈跟踪内（接近末尾）的是以下关键信息：

sun.security.validator.ValidatorException：PKIX 路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到请求目标的有效证书路径

这表明异常是由于服务器证书不受信任造成的。 X.509 证书包含信任链的描述（例如，A 签署了 B 的证书，B 签署了服务器证书），其中每个部分都作为证书完成（是的，它们是嵌套的）。为了使该链有效，链上的某些证书​​（通常是根证书，在上面的示例中为 A）必须受到客户端的信任，因为这可以防止一整类微不足道的攻击（任何人完全可以创建证书或证书链；执行此操作的软件是免费提供的）。

有关如何使用信任信息配置 CXF 的文档有点稀疏，但这里是摘要。首先，将服务器证书（如果不是自签名的，则将其上游的最顶层证书）放入 JKS 格式的密钥库中（例如，serverIdentity.jks，使用密码 jkspass 进行保护）。其次，使用有关信任内容的信息配置 CXF 的 http 管道：

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:sec="http://cxf.apache.org/configuration/security"
  xmlns:http="http://cxf.apache.org/transports/http/configuration"
  xsi:schemaLocation="
      http://cxf.apache.org/configuration/security
      http://cxf.apache.org/schemas/configuration/security.xsd
      http://cxf.apache.org/transports/http/configuration
      http://cxf.apache.org/schemas/configuration/http-conf.xsd
      http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

   <http:conduit name="*.http-conduit"> <!-- replace with real conduit name -->
       <http:tlsClientParameters>
          <sec:trustManagers>
              <sec:keyStore type="JKS" password="jkspass"
                   file="my/file/dir/serverIdentity.jks"/>
          </sec:trustManagers>
      </http:tlsClientParameters>

      <!-- assume user/pass over https; common case -->
      <http:authorization>
         <sec:UserName>foo</sec:UserName>
         <sec:Password>bar</sec:Password>
      </http:authorization>

      <!-- Below is where normal http control goes -->
      <http:client AutoRedirect="true" Connection="Keep-Alive"/>
   </http:conduit>
</beans>

以上基于 CXF 文档，其中还描述了您可能需要的许多其他选项。例如，您可能需要将 disableCNcheck="true" 属性定义添加到 元素；如果您使用直接已知且可信的自签名证书，则几乎不需要确保服务的预期主机名与服务器证书的公用名 (CN) 字段的相关子字段相匹配。或者，您可能需要提供加密客户端身份（请参阅该链接中的示例）。
