要解决"Aache-CXF WS客户端与Eclipse MOXY JAXBContextFactory不发送安全头"的问题，您可以尝试以下解决方法。

1. 创建一个CustomJAXBContextFactory类，继承自Eclipse MOXY的JAXBContextFactory类，并重写createJAXBContext方法。在方法中添加代码以发送安全头。

import org.eclipse.persistence.jaxb.JAXBContextFactory;

public class CustomJAXBContextFactory extends JAXBContextFactory {

    public static JAXBContext createJAXBContext(String contextPath, ClassLoader classLoader, Map properties) throws JAXBException {
        // 调用父类方法创建JAXBContext
        JAXBContext context = super.createJAXBContext(contextPath, classLoader, properties);

        // 添加发送安全头的代码
        Client client = ClientProxy.getClient(context);
        HTTPConduit conduit = (HTTPConduit) client.getConduit();
        HTTPClientPolicy policy = conduit.getClient();
        policy.setAllowChunking(false); // 禁用分块传输
        // 设置其他安全相关的参数

        return context;
    }
}

2. 在您的CXF客户端代码中，使用CustomJAXBContextFactory替代默认的JAXBContextFactory。

import org.apache.cxf.jaxrs.client.WebClient;
import org.apache.cxf.jaxrs.client.JAXRSClientFactoryBean;

public class MyClient {

    public static void main(String[] args) {
        // 创建JAXRSClientFactoryBean
        JAXRSClientFactoryBean bean = new JAXRSClientFactoryBean();
        bean.setAddress("http://localhost:8080/api");  // 设置服务端地址
        bean.setResourceClass(MyService.class);  // 设置服务类

        // 设置CustomJAXBContextFactory
        Map properties = new HashMap<>();
        properties.put(JAXBContextFactory.CUSTOM_CONTEXT_FACTORY, new CustomJAXBContextFactory());
        bean.setProperties(properties);

        // 创建WebClient
        WebClient client = bean.createWebClient();

        // 发送请求
        Response response = client.get();
        System.out.println(response.readEntity(String.class));

        // 关闭客户端
        client.close();
    }
}

这样，您的Aache-CXF WS客户端就会使用CustomJAXBContextFactory发送安全头了。请根据您的需求添加适当的安全头参数。
