我嘗試開發從服務器發送文件到客戶端的Web服務。我使用Apache CXF開發Web Serivce。應用程序是基於Spring的。首先，我試着寫簡單的測試代碼：使用Apache CXF通過Web服務下載文件
的applicationContext.xml
<import resource="classpath:META-INF/cxf/cxf.xml"/>
<import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
<bean class="com.llth.paymentgateway.webservice.PaymentGatewayReportingWebServiceImpl" id="paymentGatewayReportingWebService"/>
<jaxws:endpoint id="reportingWebService" implementor="#paymentGatewayReportingWebService" address="/ReportingWebService">
<jaxws:properties>
<entry key="mtom-enabled" value="true"/>
</jaxws:properties>
</jaxws:endpoint>
PaymentGatewayReportingWebService.java Web服務inteface
@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
public interface PaymentGatewayReportingWebService {
@WebMethod(operationName = "downloadFile")
public DataHandler downloadFile(String fileName);
}
PaymentGatewayReportingWebServiceImpl.java實施PaymentGatewayReportingWebService的inteface
@WebService(endpointInterface = "com.llth.paymentgateway.webservice.PaymentGatewayReportingWebService")
public class PaymentGatewayReportingWebServiceImpl implements PaymentGatewayReportingWebService {
@Override
@XmlMimeType("application/octet-stream")
public DataHandler downloadFile(String fileName) {
FileDataSource dataSource = new FileDataSource(fileName);
return new DataHandler(dataSource);
}
}
當我即時通訊端口和執行Web服務方法通過的soapUI我recevie以下響應（從RAW選項卡複製）

的soapUI不下載任何東西。我不知道一切是否正確。如果soapUI開始下載文件？如果soapUI應該下載文件，那麼有些地方是錯誤的。如果是，那有什麼問題？
