[英]unable to marshal type […] as an element because it is missing an @XmlRootElement annotation
[英]Unable to marshal type as XML element because @XmlRootElement annotation is missing
我想将对象编组为XML。
但是,它失败,但有例外:
javax.xml.bind.MarshalException
- with linked exception:

实际上,这个注释存在(对于父类和交付类):
@XmlRootElement(name = "Freight_Offer")
@XmlAccessorType(XmlAccessType.FIELD)
@JsonIgnoreProperties(ignoreUnknown = true)
@JsonInclude(JsonInclude.Include.NON_EMPTY)
public class FreightOffer {
@JsonIgnore
@XmlTransient
private String freightId;
private String id;
private String externalSystemId;
private AddressLocation pickUp;
private AddressLocation delivery;
private FreightDescription freightDescription;
private ListContacts contacts;
private Customer customer;
private ListSla slas;
private String pushId;
private CompanyProfile company;
private Route route;
private String href;
private Lifecycle lifecycle;
private Visibility visibility;
private Boolean unfoldedVXMatching;
// getters / setters
儿童班:
@XmlAccessorType(XmlAccessType.PROPERTY)
public class FreightOfferDetail extends FreightOffer {
private List<Contact> contact;
@XmlElement(name = "contacts")
@JsonProperty("contacts")
public List<Contact> getContact() {
return contact;
}
public void setContact(List<Contact> contact) {
this.contact = contact;
}
它完全失败了这个方法toXML()
:
public class ObjectTransformer<T> implements Transformer<T> {
protected final JAXBContext context;
protected final Marshaller marshaller;
protected final int okStatusCode = 200;
protected final String okSubErrorCode = "OK";
public ObjectTransformer(JAXBContext context) throws JAXBException {
this.context = context;
marshaller = context.createMarshaller();
marshaller.setProperty("jaxb.encoding", "UTF-8");
marshaller.setProperty("jaxb.formatted.output", Boolean.TRUE);
}
public String toXML(T object) throws JAXBException {
StringWriter writer = new StringWriter();
marshaller.marshal(object, writer);
String xmlOffer = writer.toString();
return xmlOffer;
}
它应该工作,但它不应该。
我在这里找不到错过或错误的地方。
更新:
这是测试的片段:
public SampleResult runTest(JavaSamplerContext context) {
AbstractSamplerResults results = new XMLSamplerResults(new SampleResult());
results.startAndPauseSampler();
if (failureCause != null) {
results.setExceptionFailure("FAILED TO INSTANTIATE connectTransformer", failureCause);
} else {
FreightOfferDTO offer = null;
FreightOffer freightOffer = null;
try {
results.resumeSampler();
RouteInfo routeDTO = SamplerUtils.getRandomRouteFromRepo(context.getIntParameter(ROUTES_TOUSE_KEY));
offer = FreightProvider.createRandomFreight(routeDTO, createUserWithLoginOnly(context));
freightOffer = connectTransformer.fromDTO(offer);
String xmlOfferString = connectTransformer.toXML(freightOffer); // <- it fails here.
我从CSV文件中取出日期并转换为DTO对象。 这个方法返回给我FreightOfferDetail.
以下是此方法的代码段:
public FreightOfferDetail freightFromDTO(FreightOfferDTO freightDTO, boolean fullFormat){
FreightOfferDetail freight = new FreightOfferDetail();
freight.setFreightId(freightDTO.getIds().getAtosId());
freight.setId(freightDTO.getIds().getFxId());
// ...
在这种情况下,如何将对象编组为XML文件?
public String toXML(T object) throws JAXBException {
StringWriter stringWriter = new StringWriter();
JAXBContext jaxbContext = JAXBContext.newInstance(T.class);
Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
// format the XML output
jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
QName qName = new QName("com.yourModel.t", "object");
JAXBElement<T> root = new JAXBElement<Bbb>(qName, T.class, object);
jaxbMarshaller.marshal(root, stringWriter);
String result = stringWriter.toString();
LOGGER.info(result);
return result;
}
这是我在没有@XmlRootElement的情况下编组/解组时使用的文章: http : //www.source4code.info/2013/07/jaxb-marshal-unmarshal-with-missing.html
所有最好的希望它有帮助:)
请注意,错误消息涉及FreightOfferDetail
,而不是FreightOffer
。
基于此,我希望在某个地方(在提供的代码之外),你要求细节被编组。
如果您希望能够这样做(使用JAXB ?),您还需要使用XmlRootElement注释来注释该类。
您可以使用ObjectFactory类来解决没有@XmlRootElement的类 。 ObjectFactory有重载方法。
方法:1它可以简单地创建对象和
方法:2它将使用@JAXBElement包装对象。
总是使用方法:2来避免javax.xml.bind.MarshalException - 链接异常缺少@XmlRootElement注释
制法:1
public GetCountry createGetCountry() {
return new GetCountry();
}
方法:2
@XmlElementDecl(namespace = "my/name/space", name = "getCountry")
public JAXBElement<GetCountry> createGetCountry(GetCountry value) {
return new JAXBElement<GetCountry>(_GetCountry_QNAME, GetCountry.class, null, value);
}
有关更多信息,请参阅此stackoverflow问题
希望这会有所帮助......
使用apache-cxf maven-plugin从WSDL创建Java对象时,使用sth。 喜欢:
<plugin>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-codegen-plugin</artifactId>
...
</plugin>
将会有一个自动生成的ObjectFactory。
在Java中配置Exception时,可以使用此生成的ObjectFactory返回错误。 重要的一步是在异常的JAXBElement<YourSoapFault>
()方法中返回JAXBElement<YourSoapFault>
。
@WebFault(name = "YourSoapFault",
targetNamespace = "ns://somenamespace")
public class SomeWebServiceException extends RuntimeException {
private final YourSoapFault fault;
public SomeWebServiceException(String message, YourSoapFault fault) {
super(message);
this.fault = fault;
}
public SomeWebServiceException(String message, YourSoapFault fault, Throwable e) {
super(message, e);
this.fault = fault;
}
public JAXBElement<YourSoapFault> getFaultInfo() {
return new ObjectFactory().createYourSoapFault(fault);
}
}
