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>

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。
