JAXB-IllegalAnnotationExceptions

Question

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，使用

com.sun.xml.bind.v2.runtime.IllegalAnnotationsExceptions： 1次IllegalAnnotationExceptions没有ObjectFactory与@XmlElementDecl的元素{}Measure_Value_Max。

我要怎么做才能解决这个问题？

我使用Netbean 7.4和jdk1.7。

此外，在我的模式的另一部分中，这种类型的限制工作正常！为什么啊？

<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>

There's no ObjectFactory with an @XmlElementDecl for the element {}Measure_Value_Max.
this problem is related to the following location:

Answer 1

要获取ObjectFactory进程，您需要将其作为用于引导JAXBContext的类之一传入，或者在生成模型的包名称上创建JAXBContext。
