Question

我知道有很多问题，但问题是，我搜索并搜索了它周围的一切，但没有发现可以帮助我。

我尝试使用Apache CXF / Wildfly 8x / Java 1.7 / Maven 3 + / Eclipse实现基于SOAP的Web服务客户端。

我成功生成了代理类，实现了ws-security选项，添加了keystore和trustore，但发现了一个非常奇怪的问题。

当我读到有关该异常时，它意味着，

这是因为您的代码所依赖的类文件它出现在编译时但在运行时找不到。寻找构建时和运行时类路径的差异。

来源stackoverflow explanation

当然，我清理并重建项目，重启eclipse但没有反应。
然后我做了一个简单的小项目并将代码复制到那里，仍然存在同样的问题。
然后我在maven repos中搜索了这个类，找到了它，打开了jar并找到了这个类。
然后我创建了可运行的jar并在我的伙伴PC中复制，在那里检查了同样的问题。
搜索了很多，但没有特别的发现。
我发现的唯一有趣的文章是CXF，但无法理解。

大多数用例不再需要ClientProxy.getClient（代理）。客户端代理实例现在直接实现客户端API。一个直接投到客户应该工作。

我甚至不知道如何开始修复它，如何调试它。这是我写的代码。

private void adjustServiceConfiguration(Object port, String address) throws IOException {
        org.apache.cxf.endpoint.Client client = ClientProxy.getClient(port);
        HTTPConduit http = (HTTPConduit) client.getConduit();
        HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
        httpClientPolicy.setConnectionTimeout(/* uccConnectionTimeout.value() */6 * 1000);
        httpClientPolicy.setReceiveTimeout(/* uccTimeout.value() */7 * 1000);
        http.setClient(httpClientPolicy);

        ((BindingProvider) port).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, address);
        ((BindingProvider) port).getRequestContext().put("set-jaxb-validation-event-handler", "false");

        Map<String, Object> outProps = new HashMap<>();
        outProps.put(WSHandlerConstants.ACTION, "Timestamp Signature Encrypt");//
        outProps.put(WSHandlerConstants.PASSWORD_TYPE, "PasswordDigest");
        outProps.put(WSHandlerConstants.USER, "ucc-agent");
        outProps.put(WSHandlerConstants.SIGNATURE_USER, "ucc-agent");
        outProps.put(WSHandlerConstants.PW_CALLBACK_CLASS, "com.ddrc.service.service.ws.KeyStorePasswordsCallback");
        outProps.put(WSHandlerConstants.ENCRYPTION_USER, "ucc");

        if (encryptionProps == null || signProps == null) {
            try {
                encryptionProps = new Properties();
                signProps = new Properties();
                try (FileInputStream fis1 = new FileInputStream(
                        uccEncryptionPropFile);
                        FileInputStream fis2 = new FileInputStream(
                                uccSignaturePropFile);) {
                    encryptionProps.load(fis1);
                    signProps.load(fis2);
                }
            } catch (IOException ex) {
                throw ex;
                // log.error("Error occurred during UCC WS-Security configuration file lookup",
                // ex);
            }
        }

        outProps.put("encryptionProps", encryptionProps);
        outProps.put("signProps", signProps);
        outProps.put(WSHandlerConstants.ENC_PROP_REF_ID, "encryptionProps");
        outProps.put(WSHandlerConstants.SIG_PROP_REF_ID, "signProps");

        Map<String, Object> inProps = new HashMap<>();
        inProps.put(WSHandlerConstants.ACTION, "Timestamp Signature Encrypt");
        inProps.put(WSHandlerConstants.PASSWORD_TYPE, "PasswordText");
        inProps.put(WSHandlerConstants.PW_CALLBACK_CLASS, "com.ddrc.service.service.ws.KeyStorePasswordsCallback");
        inProps.put(WSHandlerConstants.ALLOW_RSA15_KEY_TRANSPORT_ALGORITHM, "true");

        inProps.put("signProps", signProps);
        inProps.put("encryptionProps", encryptionProps);
        inProps.put(WSHandlerConstants.DEC_PROP_REF_ID, "signProps");
        inProps.put(WSHandlerConstants.SIG_PROP_REF_ID, "encryptionProps");

        client.getInInterceptors().add(new WSS4JInInterceptor(inProps));
        client.getOutInterceptors().add(new WSS4JOutInterceptor(outProps));
        client.getInInterceptors().add(new LoggingInInterceptor());
        client.getOutInterceptors().add(new LoggingOutInterceptor());
    }

问题出在ClientProxy class

这是小项目的错误。

和全班：）

package ge.test;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.frontend.ClientProxy;

public class Run {

    public static void main(String[] args) {

        Client c = ClientProxy.getClient(null);
    }

}

使用Apache CXF，Wildfly和Java 1.7的NoClassDefFoundError
