Question

我有一个由我需要访问的服务提供的wsdl。我正在使用CXF V3.1.7，它检测到提供的wsdl的一些问题。我解决了两个问题，如下所示。但是当时有效的wsdl导致了ClassCastException

Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: org.apache.neethi.builders.PolicyContainingPrimitiveAssertion cannot be cast to org.apache.wss4j.policy.model.AlgorithmSuite

wsdl文件的相关部分是：

<wsp1:Policy sch0:Id="ConsumerServiceSoap11Policy">
<wsp1:ExactlyOne>
  <wsp1:All>
    <sp1:TransportBinding>
      <wsp1:Policy>
        <sp1:TransportToken>
          <wsp1:Policy>
            <sp1:HttpsToken RequireClientCertificate="false">
                <wsp1:Policy/>
            </sp1:HttpsToken>
          </wsp1:Policy>
        </sp1:TransportToken>
        <sp:AlgorithmSuite>
            <wsp:Policy>
                <sp:Basic256/>
            </wsp:Policy>
        </sp:AlgorithmSuite>
        <sp1:Layout>
          <wsp1:Policy>
            <sp1:Lax/>
          </wsp1:Policy>
        </sp1:Layout>
        <!--sp1:IncludeTimestamp/-->
      </wsp1:Policy>
    </sp1:TransportBinding>

我在HttpsToken元素中添加了空的Policy元素，并添加了AlgorithmSuite元素，使CXF接受它对CXF wsdl2java有效。

以下是我包含的相关CXF依赖项。

    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>${cxf.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-ws-policy</artifactId>
        <version>${cxf.version}</version>
    </dependency>
    <dependency>

        <artifactId>cxf-rt-ws-security</artifactId>

    </dependency>

如何防止此异常？

Answer 1

看起来你正在混淆命名空间定义，例如： TransportBinding具有“sp1：”而AlgorithmSuite具有“sp：”。

CXF wsdl导致org.apache.wss4j.policy.model.AlgorithmSuite的ClassCastException
