Answer 1

尝试使用WebServiceContext

  

WebServiceContext接口是JAX-WS 2.2规范第5.3节中介绍的服务API之一。为了使用Web服务上下文，请使用javax.annotation.Resource注释注入资源。

示例：

@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，请使用：

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