我尝试了下面的代码，结果为空，请提供任何其他方法将HttpServletResponse作为对象处理

尝试使用WebServiceContext

WebServiceContext interface is one of the service APIs explained in the JAX-WS 2.2 specifications, section 5.3. For using the Web services context, inject a resource by using the javax.annotation.Resource annotation.

例如：

@WebService
public class AddNumbersImpl {
    // Inject the information about the request that is currently being processed in the wsContext field
    @Resource
    private WebServiceContext wsContext;

    public int add(int number1, int number2) throws AddNumbersFault {
        // Acquire the message context
        MessageContext mContext = wsContext.getMessageContext();
        // Acquire the properties
        ServletContext sContext = (ServletContext)mContext.get(MessageContext.SERVLET_CONTEXT);

对于HttpServletResponse使用：

HttpServletResponse response = (HttpServletResponse) mContext.getMessageContext().get(MessageContext.SERVLET_RESPONSE);
