我正在尝试使用 MSF4J 开发微服务。该服务获取输入请求的标头详细信息,并尝试与 SOAP 服务通信以进行进一步操作。此逻辑在作为普通应用程序编写时工作正常,但在转换为微服务时会引发以下异常

[org.apache.axis2.context.AbstractContext] : OnDemandLogger initialized for class org.apache.axis2.context.AbstractContext is:org.apache.commons.logging.internal.JclLogger@6b972f62

微服务尝试与之通信的 SOAP 服务是 WSO2 身份服务器的“OAuth2TokenValidationService”。

包含对 SAOP 服务的调用的方法如下

 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;
    }

在将普通应用程序转换为微服务时,添加了以下依赖项。

<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 相关的依赖项是

    <dependency>
                    <groupId>org.apache.ws.commons.axiom.wso2</groupId>
                    <artifactId>axiom</artifactId>
                    <version>1.2.11.wso2v4</version>
                </dependency> 
    <dependency>

        <artifactId>woden-impl-dom</artifactId>
        <version>1.0M8</version>
</dependency>

任何解决此问题的帮助将不胜感激。

你能试试最新的 MSF4J 2.0 版本吗?

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

这意味着,在依赖树中,很可能另一个版本的 Axiom 作为传递依赖被引入。

跑; mvn dependency:tree 并找出哪些其他版本的 Axiom 被拉入并从 Maven 构建中排除这些版本。
