MSF4J 微服务尝试与 SOAP 服务通信
MSF4J micoservice trying to communicate with a SOAP service
我正在尝试使用 MSF4J 开发微服务。该服务获取输入请求的 header 详细信息，并尝试与 SOAP 服务通信以进行进一步的操作。当作为普通应用程序编写时，此逻辑工作正常，但当转换为微服务时，它会抛出以下异常
[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"。
调用SAOP服务的方法如下
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。

<version>5.0.0-alpha</version>

如能帮助解决此问题，我们将不胜感激。
你能试试最新的 MSF4J 2.0 版本吗？
此问题的根本原因是： 原因：java.lang.NoSuchMethodError：org.apache.axiom.om.OMAbstractFactory.getMetaFactory()Lorg/apache/axiom/om/OMMetaFactory;
这意味着，在依赖关系树中，很可能另一个版本的 Axiom 作为传递依赖关系被引入。
运行； mvn dependency:tree 并找出其他版本的 Axiom 被引入并从 Maven 构建中排除这些版本。
