java - AXIS 2 Web 服务访问中的 ClassCastException : RequestURIBasedDispatcher

我正在将 AXIS 1 Web 服务发展为 AXIS 2。我已成功部署没有处理程序的 Web 服务，并且它们运行良好，但现在，我正在尝试添加处理程序以处理 SOAP header (安全原因)。在 AXIS 1 中，我在 WSDD 文件中定义了处理程序，但根据 AXIS 2 文档，现在我需要定义一个模块，以便将处理程序包含到 AXIS 引擎中。但是，在我的 WildFly 服务器中部署该服务后，我向该服务发送 SOAP 请求，并收到以下响应:

<html>
<head>
...
</head>
<body>
    <div class="header">
        <div class="error-div"/>
        <div class="error-text-div">Error processing request</div>
    </div>
    <div class="label">Context Path:</div>
    <div class="value">/pao</div>
    <br/>
    <div class="label">Servlet Path:</div>
    <div class="value">/services</div>
    <br/>
    <div class="label">Path Info:</div>
    <div class="value">/PAOSynchronizationServiceSOAP</div>
    <br/>
    <div class="label">Query String:</div>
    <div class="value">null</div>
    <br/>

我使用了maven插件“axis2-repo-maven-plugin”来生成.mar和.list文件。services.xml 是这样的:

    <service name="PAOSynchronizationServiceSOAP" targetNamespace="urn:es:pao:services:messages:1.0.0">
    <description>Servicios PAO.</description>
    <module ref="AuthModule" />
    <schema schemaNamespace="urn:es:pao:services:messages:1.0.0" />
    <parameter name="ServiceClass" locked="false">es.gob.afirma.pao.impl.PAOSynchronizationServiceSOAPBindingImpl
    </parameter>
    <!-- <parameter name="disableSOAP11" locked="true">true</parameter> -->
    <parameter name="disableREST" locked="false">true</parameter>
    <messageReceivers>
        <messageReceiver mep="http://www.w3.org/ns/wsdl/in-out"
            class="es.gob.afirma.pao.utilities.PAOSynchronizationServiceMessageReceiverInOut" />
    </messageReceivers>
</service>

模块.xml:

<module name="AuthModule" class="es.gob.afirma.pao.utilities.AuthModule">
<InFlow>
    <handler name="AuthHandler" class="es.gob.afirma.pao.impl.AuthHandler">
        <order phase="Security" />
    </handler>
</InFlow>

<OutFlow>
</OutFlow>

<OutFaultFlow>
</OutFaultFlow>

<InFaultFlow>
</InFaultFlow>

默认情况下模块实现(使用空方法)，并且处理程序扩展为 AbstractHandler 类。

我做错了什么？

最佳答案

终于，我发现了问题所在。我添加了“rampart”依赖项，该依赖项与其他 Axis 库冲突，因此，在阶段加载过程中，Axis 引擎在转换处理程序时崩溃。

我使用“rampart”依赖项来执行“axis2-mar-maven-plugin”maven 插件( following this guide )，但最后我在 axis2.xml 文件中添加了处理程序，所以，我没有需要定义Axis模块。
