我正在尝试使用MSF4J开发一个微服务。该服务获取输入请求的头部详细信息，并尝试与SOAP服务进行通信以进行进一步的操作。此逻辑在作为普通应用程序编写时运行良好，但在转换为微服务时会抛出以下异常

代码语言：javascript

微服务尝试与之通信的SOAP服务是WSO2 Identity服务器的"OAuth2TokenValidationService“。

包含对SAOP服务的调用的方法如下所示

代码语言：javascript
运行
复制
 public OAuth2TokenValidationResponseDTO validateToken(
                String accessTokenIdentifier)
                throws RemoteException, LoginAuthenticationExceptionException {


            OAuth2TokenValidationServiceStub stub = new OAuth2TokenValidationServiceStub(
                    null, server
                            + "/services/OAuth2TokenValidationService");

            ServiceClient e3 = stub._getServiceClient();
            Options option3 = e3.getOptions();
            HttpTransportProperties.Authenticator auth1 = new HttpTransportProperties.Authenticator();
            auth1.setUsername(utUsername);
            auth1.setPassword(utPassword);
            auth1.setPreemptiveAuthentication(true);
            option3.setManageSession(true);
            /*option2.setProperty(Constants.Configuration.MESSAGE_TYPE,HTTPConstants.MEDIA_TYPE_APPLICATION_ECHO_XML);
            option2.setProperty(Constants.Configuration.DISABLE_SOAP_ACTION,Boolean.TRUE);*/
            option3.setProperty(org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE, auth1);
            /*option2.setProperty("Cookie", authCookie);*/
            e3.setOptions(option3);

            OAuth2TokenValidationRequestDTO oauthReq = new OAuth2TokenValidationRequestDTO();

            OAuth2TokenValidationRequestDTO_OAuth2AccessToken accessToken = new OAuth2TokenValidationRequestDTO_OAuth2AccessToken();
            accessToken.setTokenType("Bearer");
            accessToken.setIdentifier(accessTokenIdentifier);
            oauthReq.setAccessToken(accessToken);
            oauthReq.setRequiredClaimURIs(null);

            OAuth2TokenValidationResponseDTO resp = stub.validate(oauthReq);


return resp;
    }

将普通应用程序转换为微服务时，添加了以下依赖。

代码语言：javascript
运行
复制
<dependency>
            <groupId>org.wso2.carbon</groupId>
            <artifactId>org.wso2.carbon.transport</artifactId>
            <version>5.0.0-alpha</version>
             <exclusions>
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-api</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

与AXIOM相关的依赖项包括

代码语言：javascript
运行
复制
    <dependency>
                    <groupId>org.apache.ws.commons.axiom.wso2</groupId>
                    <artifactId>axiom</artifactId>
                    <version>1.2.11.wso2v4</version>
                </dependency> 
    <dependency>
        <groupId>org.apache.woden</groupId>
        <artifactId>woden-impl-dom</artifactId>
        <version>1.0M8</version>
</dependency>

任何帮助解决这个问题的人都将不胜感激。

您可以尝试使用最新的MSF4J 2.0版本吗？

此问题的根本原因是:由: org.apache.axiom.om.OMAbstractFactory.getMetaFactory()Lorg/apache/axiom/om/OMMetaFactory；：java.lang.NoSuchMethodError引起

这意味着，在依赖关系树中，最有可能的是Axiom的另一个版本被拉入作为传递依赖关系。

运行；mvn依赖:树，找出Axiom的其他版本，并从Maven构建中排除这些版本。
