Question

需要使用jsp页面显示xml响应。我正在获取xml对象的对象“vehicleOrderResponse”，如果我将在新文件中显示此对象，则xml显示成功，但未在jsp页面中获取xml数据。提供任何代码片段以在jsp页面中显示xml响应？

Jsp页面代码：

try
        {
            SAMSServiceAdaptor serviceadaptor = new SAMSServiceAdaptor();
            VehicleOrderDetailRequestType vehicleOrderDetailRequest = serviceadaptor.createRequest(
                    vin, bodyCode, dealerCode, ordernumber, modelYear);
            vehicleOrderResponse = SAMSServiceLocator.getSAMSServicePort().retrieveVehicleOrderDetail(vehicleOrderDetailRequest);
            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            JAXBContext context = JAXBContext
                        .newInstance(VehicleOrderDetailResponseType.class);
            Marshaller marshaller = context.createMarshaller();
            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,
                        true);
            marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
            marshaller.marshal(vehicleOrderResponse, bytes);
            String sb = new String(bytes.toByteArray());
            String responseXML = sb.trim();
            if(responseXML!=null){
                out.println(responseXML.trim().substring("<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>".length()));    
            }else{
                    out.println("Response was null, Please check input paramters! ");
                }

        }
        catch(Exception ex)
        {
            out.println(ex.toString());
        }

文件中的Xml响应： -

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:VehicleOrderType xmlns="urn:ford/interface/VehicleOrder/UnitDetail/v2" xmlns:ns2="urn:ford/VehicleOrder/UnitDetail/v2.0">
    <VehicleOrder>
        <ModelYear>2014</ModelYear>
        <Dealer>13058</Dealer>
        <Body>P8J</Body>
        <ItemNo>445S  </ItemNo>
        <Vin>1ZVBP8JZ3E5223527</Vin>
        <Division>F                             </Division>
        <GsdbSiteCode>G9W1A</GsdbSiteCode>
        <CurrentBuildWeek>2013-04-01Z</CurrentBuildWeek>
        <ReceiptDate>2013-03-07Z</ReceiptDate>
        <VehicleLineDescription>Mustang</VehicleLineDescription>
        <BodyDescription>P8J Coupe Shelby GT500</BodyDescription>
        <Status>
            <ns2:Status>Sold                          </ns2:Status>
            <ns2:StatusDateTime>2013-05-04T04:00:00.000Z</ns2:StatusDateTime>
        </Status>
    </VehicleOrder>
</ns2:VehicleOrderType>

您可以通过将预先格式化的XML内容包装在<pre>标记内来预先指定格式，以防止浏览器将其解释为HTML并按原样显示：

<pre>
    <%
      // your existing code
    %>
</pre>

更好的选择是将JSP scriptlet <% %>代码移出到Servlet中，该Servlet将XML内容设置为请求属性，然后使用{{}将请求转发给JSP 1}}。

RequestDispatcher

然后，最后在您的JSP中使用JSTL的String responseXML = new String(bytes.toByteArray()).trim(); if (responseXML != null) { request.setAttribute("responseXML", responseXML.substring( "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>".length())); }标记。这将自动为您转义XML。
