在Apache CXF中包含空SOAP body参数需要什么配置？

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
import org.apache.cxf.message.Message;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;

public class EmptyBodyInterceptor extends AbstractPhaseInterceptor<Message> {

    public EmptyBodyInterceptor() {
        super(Phase.PRE_INVOKE);
    }

    @Override
    public void handleMessage(Message message) {
        if (message.getContent(List.class) == null || message.getContent(List.class).isEmpty()) {
            // 处理空SOAP body的情况
            System.out.println("Empty SOAP Body detected.");
            // 可以在这里添加更多的处理逻辑，比如抛出异常或填充默认值
        }
    }
}

public class ServicePublisher {
    public static void main(String[] args) {
        MyService service = new MyServiceImpl();
        JaxWsServerFactoryBean svrFactory = new JaxWsServerFactoryBean();
        svrFactory.setServiceClass(MyService.class);
        svrFactory.setAddress("http://localhost:8080/myService");
        svrFactory.setServiceBean(service);

        // 添加拦截器
        svrFactory.getInInterceptors().add(new LoggingInInterceptor());
        svrFactory.getOutInterceptors().add(new LoggingOutInterceptor());
        svrFactory.getInInterceptors().add(new EmptyBodyInterceptor());

        svrFactory.create();
    }
}
