java - 尝试在 WSO2 Identity Server 中创建 ServiceProvider 时出现 ArrayIndexOutOfBoundsException

Question

我正在尝试从 Java 客户端调用 SOAP API 以在 Identity Server 中创建服务提供程序。

我已在服务器上启用管理服务，并使用 Apache CXF codegen 插件从位于 /services/IdentityApplicationManagementService?wsdl 的 WSDL 文件生成 stub ，如所述 here (注意:文档适用于 5.9.0，但应该与我的 IDS 版本非常相似)

我可以成功调用其他端点，例如列出所有可用的服务提供商，如下所示:

public static void listAllApplications() throws IdentityApplicationManagementServiceIdentityApplicationManagementException {
    IdentityApplicationManagementService service = new IdentityApplicationManagementService();
    IdentityApplicationManagementServicePortType port = service.getIdentityApplicationManagementServiceHttpsSoap12Endpoint();
    Map<String, Object> requestContext = ((BindingProvider) port).getRequestContext();
    requestContext.put(BindingProvider.USERNAME_PROPERTY, "username");
    requestContext.put(BindingProvider.PASSWORD_PROPERTY, "password");
    List<ApplicationBasicInfo> allApplicationBasicInfo = port.getAllApplicationBasicInfo();
    allApplicationBasicInfo.forEach((info) -> {
        System.out.println(info.getApplicationName().getValue());
    });
} 

但是当我尝试创建新的服务提供商时

public static void createApplication() throws IdentityApplicationManagementServiceIdentityApplicationManagementException {
    CreateApplication serviceProviderRequest = new axis2.apache.org.xsd.ObjectFactory().createCreateApplication();
    org.wso2.carbon.identity.application.common.model.xsd.ObjectFactory applicationObjectFactory
            = new org.wso2.carbon.identity.application.common.model.xsd.ObjectFactory();
    ServiceProvider serviceProvider = applicationObjectFactory.createServiceProvider();
    serviceProvider.setApplicationName(applicationObjectFactory.createApplicationBasicInfoApplicationName("SOAP"));
    serviceProvider.setDescription(applicationObjectFactory.createApplicationBasicInfoDescription("Java"));
    serviceProviderRequest.setServiceProvider(convertToJAXBElement(serviceProvider));
    IdentityApplicationManagementService service = new IdentityApplicationManagementService();
    IdentityApplicationManagementServicePortType port = service.getIdentityApplicationManagementServiceHttpsSoap12Endpoint();
    Map<String, Object> requestContext = ((BindingProvider) port).getRequestContext();
    requestContext.put(BindingProvider.USERNAME_PROPERTY, "username");
    requestContext.put(BindingProvider.PASSWORD_PROPERTY, "password");
    port.createApplication(serviceProviderRequest);
}


public static JAXBElement<ServiceProvider> convertToJAXBElement(ServiceProvider provider) {
    if (null == provider) {
        return null;
    }
    QName name = new QName("http://script.model.common.application.identity.carbon.wso2.org/xsd", "ServiceProvider");
    return new JAXBElement(name, ServiceProvider.class, provider);
}

这是此调用生成的请求

<?xml version="1.0" encoding="UTF-8"?>

         </ns2:ServiceProvider>
      </ns4:createApplication>
   </S:Body>
</S:Envelope>

我在客户端收到以下错误:

身份服务器上的服务器日志 (wso2carbon.log) 报告以下内容:

我在客户端使用 WSO2 Identity Server 版本 5.8 和 Java 8。

我没有搞乱 Axis2 或 Identity Server 上的任何相关内容，这是在全新安装中发生的。据我了解，这要么是我做错了(最有可能)，要么是 Axis2 库中的错误，但我陷入了困境。如果需要，我可以提供任何其他所需的文件，例如 WSDL。请指教。

Answer 1

事实证明这是我的一个错误，特别是在 convertToJAXBElement() 方法上。

我输错了 QName 的本地部分。将其编辑为

public static JAXBElement<ServiceProvider> convertToJAXBElement(ServiceProvider provider) {
    if (null == provider) {
        return null;
    }
    QName name = new QName("http://script.model.common.application.identity.carbon.wso2.org/xsd", "serviceProvider"); // Note the localpart
    return new JAXBElement(name, ServiceProvider.class, provider);
}

似乎已经解决了问题。
