java - 使用 Apache CXF 通过 Web 服务下载文件

Question

我尝试开发Web服务，将文件从服务器发送到客户端。我使用 Apache CXF 来开发 Web 服务。应用程序是基于Spring的。首先我尝试编写简单的测试代码:

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 服务接口(interface)

@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
public interface PaymentGatewayReportingWebService {

    @WebMethod(operationName = "downloadFile")
    public DataHandler downloadFile(String fileName);

}

PaymentGatewayReportingWebServiceImpl.java 实现 PaymentGatewayReportingWebService 接口(interface)

@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);
    }
}

当我通过soapUI导入并执行Web服务方法时，我收到以下响应(从RAW选项卡复制)

soapUI 不下载任何内容。我不知道一切是否正确。 soapUI 应该开始下载文件吗？如果soapUI 应下载该文件，则说明有问题。如果是的话，有什么问题吗？

Answer 1

事实上，soapUI 正在给你正确的答案。 “这里有一些二进制数据”是您要求的文件
