java - 非法参数异常 : ProtectionToken is not a <wsp:Policy> element

Question

几个小时以来，我一直在努力解决 Axis2 和 Rampart 的问题。我已经在谷歌上进行了广泛的搜索，但尚未找到解决方案。我什至查看了源代码并使用调试器单步调试它。尽管这让我了解了错误及其原因，但它并没有让我更接近解决方案。

发生的错误是

java.lang.IllegalArgumentException: {http://schemas.xmlsoap.org/ws/2005/07/securitypolicy}ProtectionToken is not a <wsp:Policy> element.

虽然我以前使用过 Axis2，但我并不是这方面的专家，更不是 Rampart 方面的专家。我有一个现有的 Web 应用程序，它已被扩展以引入用于 Web 服务交互的客户端。我按照说明安装了 Axis2 v1.6.1 和 Rampart v1.6.1。我使用 WSDL2Java 脚本构建了客户端 Java 类，并将生成的类捆绑到一个 jar 中。然后，我将适当的 jar 和 Axis2 存储库添加到 Web 应用程序。 WSDL 和 XSD 包含在 http://mail-archives.apache.org/mod_mbox/axis-java-user/201112.mbox/%3C4B95BC7335A13A42AD0D23462F91AE6F615D057F41%40echo.geometryit.com%3E 的 wsdl.zip 附件中。 (Axis2 用户邮件列表)附件位于页面底部。

初始化 Web 服务客户端的代码部分是

try
{
  ConfigurationContext context = ConfigurationContextFactory.createConfigurationContextFromFileSystem(this.getWebInfPath() + "repository" );

**ablisContentManagementService = new ContentManagementServiceStub( context, "http://services.ablis.uat.business.gov.au/ContentManagement.svc" );

  ServiceClient ablisContentManagementServiceClient = ablisContentManagementService._getServiceClient();

  ablisContentManagementServiceClient.engageModule( "addressing" );
  ablisContentManagementServiceClient.engageModule( "rampart" );

  ablisAxisFault = null;
}
catch ( AxisFault af )
{
  ablisContentManagementService = null;
  ablisAxisFault = af;
  af.printStackTrace();
}
catch ( Throwable t )
{
  t.printStackTrace();
}

我知道 Rampart 未正确配置，但错误是在突出显示的行 (**) 处引发的。如果完成的话，这是在进行 Rampart 配置之前。

在调试中，我注意到 XML 作为 OMElement 实例传递给 SymmetricBindingBuilder.build() (请参阅堆栈跟踪)(为简洁起见，进行了删减)

<wsp:Policy>
  <sp:ProtectionToken>
    .
    .
    .
  </sp:ProtectionToken>
  .
  .
  .
</wsp:Policy>

从 SymmetricBindingBuilder.build() 中的代码来看，我认为 XML 应该是:

<sp:SymmetricBinding xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
  <wsp:Policy>
    <sp:ProtectionToken>
      .
      .
      .
    </sp:ProtectionToken>
    .
    .
    .
  </wsp:Policy>
</sp:SymmetricBinding>

对传递的 XML 进行更改可以修复错误，但如何完成此操作。

为了简短起见，我的言论或行为可能有错误或遗漏。如果缺少重要细节，请突出显示这些细节。我熟悉 Axis2，但完全不熟悉 Rampart，因此非常感谢您的帮助。我很乐意回答问题。非常感谢任何帮助。

我猜您已经解决了这个问题。但对我来说，这是一个新鲜的、生硬的、发痒的伤口。经过几个小时的努力解决几乎完全相同的问题，我终于找到了解决方案。

在生成的客户端代码中，例如 ClientStub，有一个静态 getPolicy() 函数需要对此进行调整(调整空格以提高可读性):

private static org.apache.neethi.Policy getPolicy (java.lang.String policyString) 
{
  java.io.ByteArrayInputStream bais = new java.io.ByteArrayInputStream(policyString.getBytes());
  return org.apache.neethi.PolicyEngine.getPolicy(bais);
}

对此:

private static org.apache.neethi.Policy getPolicy (java.lang.String policyString) 
{
  java.io.ByteArrayInputStream bais = new java.io.ByteArrayInputStream(policyString.getBytes());
  try 
  {
    StAXOMBuilder builder = new StAXOMBuilder(bais);
    OMElement documentElement = builder.getDocumentElement();
    return org.apache.neethi.PolicyEngine.getPolicy(documentElement);
  } 
  catch (XMLStreamException e) 
  {
    e.printStackTrace();
  }
  return null;
}

我在 this mail thread 中遇到了这个解决方案.
