我有一个这样的XSD:
<xs:element name="Measure">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" ref="Measure_Id"/>
<xs:choice minOccurs="1" maxOccurs ="4">
<xs:element ref="Measure_Value"/>
<xs:element ref="Measure_Value_Max"/>
<xs:element ref="Measure_Value_Min"/>
<xs:element ref="Measure_Value_Average"/>
</xs:choice>
<xs:element minOccurs="0" ref="Files"/>
</xs:sequence>
</xs:complexType>
</xs:element>
特别是,对于
<xs:choice>
,我想指定元素Measure
必须至少具有一种Measure_Value
类型。不幸的是,这种代码会产生异常:
com.sun.xml.bind.v2.runtime.IllegalAnnotationsException:1个IllegalAnnotationExceptions计数
没有对象{} Measure_Value_Max带有@XmlElementDecl的ObjectFactory。
我该怎么做才能解决此问题?
我使用
Netbeans 7.4
和jdk1.7
。另外,在我的架构的另一部分中,这种类型的限制可以正常工作!为什么?
<xs:element name="UD_Info">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" ref="UD_Identificator"/>
<xs:choice minOccurs="1" maxOccurs ="3">
<xs:element ref="UD_Measures"/>
<xs:element ref="UD_Alarms"/>
<xs:element ref="UD_Diagnostics"/>
</xs:choice>
</xs:sequence>
</xs:complexType>
</xs:element>

最佳答案
要获取ObjectFactory
进程,您需要将其作为用于引导JAXBContext
的类之一传递,或在生成的模型的包名称上创建JAXBContext
。
