問題與JAXB和Spring OXM

我試圖來解讀一個基本的XML文件，該文件如下：問題與JAXB和Spring OXM

<?xml version="1.0" encoding="UTF-8"?> 
<personnes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="personnes.xsd"> 
    <personne> 
    <prenom>toto</prenom> 
    <nom>dupont</nom> 
    </personne> 
    <personne> 
    <prenom>titi</prenom> 
    <nom>durand</nom> 
    </personne> 
    <personne> 
    <prenom>tata</prenom> 
    <nom>lanvin</nom> 
    </personne> 
</personnes>

相應的XSD是在這裏：

<?xml version="1.0" encoding="UTF-8"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
    <xs:element name="personnes"> 
     <xs:complexType> 
      <xs:sequence> 
       <xs:element name="personne" maxOccurs="unbounded"> 
        <xs:complexType> 
         <xs:sequence> 
          <xs:element name="prenom" type="xs:string" /> 
          <xs:element name="nom" type="xs:string" /> 
         </xs:sequence> 
        </xs:complexType> 
       </xs:element> 
      </xs:sequence> 
     </xs:complexType> 
    </xs:element> 
</xs:schema>

我係統地得到一個UnmarshallingFailureException：

您的信息我使用Spring OXM。

我強烈懷疑這與我的XSD架構做，可能命名空間...

任何人都可以請幫助？

編輯：下面是相關的Spring配置：

<bean id="personneItemReader" class="org.springframework.batch.item.xml.StaxEventItemReader"> 
     <property name="resource" value="classpath:personnes.xml" /> 
     <property name="fragmentRootElementName" value="personne" /> 
     <property name="unmarshaller" ref="jaxb2Marshaller" /> 
    </bean> 

    <bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> 
     <property name="classesToBeBound"> 
      <list> 
       <value>com.docapost.batch.xml.Personnes</value> 
      </list> 
     </property> 
     <property name="schema" value="classpath:personnes.xsd" /> 
    </bean>

編輯2：異常跟蹤，如果我註釋掉架構驗證：

當您在Spring環境之外運行JAXB時，是否看到相同的異常？ – 2012-07-06 15:14:11

好點：它可以在Spring以外的地方使用... – balteo 2012-07-06 15:47:03

你可以發佈任何Spring相關的配置嗎？ – 2012-07-06 15:49:10

似乎沒有成爲一個鏈接是personne元素和Personne類。如果你生成你的模型，你可以嘗試改變你的配置使用上下文路徑？

<bean id="personneItemReader" class="org.springframework.batch.item.xml.StaxEventItemReader"> 
    <property name="resource" value="classpath:personnes.xml" /> 
    <property name="fragmentRootElementName" value="personnes" /> 
    <property name="unmarshaller" ref="jaxb2Marshaller" /> 
</bean> 

<bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> 
    <property name="contextPath" value="ocom.docapost.batch.xml"/> 
</bean>

問題是，單個項目是「personne」標籤，而不是包含「personnes」標籤......請參閱包含的XML。 – balteo 2012-07-06 15:58:28

另請參見[spring批處理參考文檔]（http://static.springsource.org/spring-batch/reference/html/readersAndWriters.html#StaxEventItemReader） – balteo 2012-07-06 16:01:29

如果註釋掉'。 – 2012-07-06 16:02:23
