我正在使用JAX-WS创建一个Web服务。它是使用sun-jaxws.xml从@WebService
带注释的类创建的。
我有一个新要求,某些字段既可选又可以为nillable。对于这样的字段,如果传递nill,我必须写DB NULL,但如果没有传递值,我不应该触及DB值。
为了能够区分这些情况我试图将@XmlElementRef
添加到这些字段,但JAXB失败并出现以下错误:
SEVERE: WSSERVLET11: failed to parse runtime descriptor: javax.xml.ws.WebServiceException: Unable to create JAXBContext
javax.xml.ws.WebServiceException: Unable to create JAXBContext
at com.sun.xml.ws.model.AbstractSEIModelImpl.createJAXBContext(AbstractSEIModelImpl.java:164)
at com.sun.xml.ws.model.AbstractSEIModelImpl.postProcess(AbstractSEIModelImpl.java:94)
[...]
Caused by: java.security.PrivilegedActionException: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
There's no ObjectFactory with an @XmlElementDecl for the element {}lastName.
this problem is related to the following location:
at private javax.xml.bind.JAXBElement com.example.test.Person.lastName
at com.example.test.Person
at public com.example.test.Person com.example.test.jaxws.UpdatePerson.person
at com.example.test.jaxws.UpdatePerson
问题。可以使用JAX-WS完成此任务吗?如果没有,解决此类问题的常用方法是什么?
这是我最小的完整示例:
@XmlType(name = "Person")
@XmlAccessorType(XmlAccessType.FIELD)
public class Person {
@XmlElementRef(name="lastName")
private JAXBElement<String> lastName;
public JAXBElement<String> getLastName() {
return lastName;
}
public void setLastName(JAXBElement<String> lastName) {
this.lastName = lastName;
}
}
我的终点:
@WebService(
serviceName="CustomTestService",
portName="DefaultPort",
targetNamespace="http://ws.example.com/"
)
@SchemaValidation
public class TestEndpoint {
@WebMethod
public void updatePerson(
@WebParam(name="person") Person person
) {
// do nothing
}
}
编辑: This问题与类似主题有关,但我们不会使用请求/响应初始架构来提供xjc
。使用xjc
是使用@XmlElementRef
注释的唯一方法吗?
答案 0 :(得分:1)
您需要使用带有ObjectFactory
注释的create方法创建@XmlElememtDecl
类,该异常描述:
Caused by: java.security.PrivilegedActionException: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
There's no ObjectFactory with an @XmlElementDecl for the element {}lastName.
this problem is related to the following location:
at private javax.xml.bind.JAXBElement com.example.test.Person.lastName
它看起来像下面这样:
@XmlRegistry
public class ObjectFactory {
@XmlElementDecl(name="lastName")
public JAXBElement<String> createLastName(String value) {
return new JAXBElement<String>(new QName("lastName"), String.class, value);
}
}
