我正在使用JAXB生成
XML.但是JAXB正在生成一个空标签.但我的客户想要单独的空标签.我知道两者都是平等但他不同意我的看法.请任何人建议解决方案.谢谢.
示例代码:
@XmlAccessorType(XmlAccesstype.FIELD) @XmlType(name = "",propOrder = { "currencyCode","discountValue","setPrice","spendLowerThreshold","spendUpperThreshold","discountApportionmentPercent","discountApportionmentValue" }) @XmlRootElement(name = "countryData") public class CountryData { protected String currencyCode; protected String discountValue = ""; protected String setPrice = ""; protected String spendLowerThreshold = ""; protected String spendUpperThreshold = ""; protected String discountApportionmentPercent = ""; protected String discountApportionmentValue = ""; // Setters and Gettres }
实际产量:
<currencyCode>GBP</currencyCode> <discountValue/> <setPrice/> <spendLowerThreshold/> <spendUpperThreshold/> <discountApportionmentPercent>0.0</discountApportionmentPercent> <discountApportionmentValue/>
预期产出:
<currencyCode>GBP</currencyCode> <discountValue></discountValue> <setPrice></setPrice> <spendLowerThreshold></spendLowerThreshold> <spendUpperThreshold></spendUpperThreshold> <discountApportionmentPercent>0.0</discountApportionmentPercent> <discountApportionmentValue></discountApportionmentValue>
编组代码:
try { Marshaller marshaller = JAXBContext.newInstance(CountryData.class).createMarshaller(); ByteArrayOutputStream os = new ByteArrayOutputStream(); marshaller.marshal(countryData,os); log.debug("The PPV request raw XML -> " + os.toString()); } catch (JAXBException e) { // nothing to do }
我正在使用JDK 6.0
如果您从
XSD生成了类,那么您还将生成ObjectFactory类.如果没有请参考
here关于如何生成ObjectFactory类.
在那之后,你的代码就像 –
JAXBContext context; context = JAXBContext.newInstance(*yourClass*.class); final ObjectFactory objFactory = new ObjectFactory(); final JAXBElement<YourClass> element = objFactory .*autoGeneratedmethodfromObjectFactorytogetelement*; Marshaller marshaller; marshaller = context.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,Boolean.TRUE); final StringWriter stringWriter = new StringWriter(); marshaller.marshal(element,stringWriter); String message = stringWriter.toString();
这将为您提供所需的输出.
