问题与JAXB和Spring OXM

我试图来解读一个基本的XML文件，该文件如下：问题与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>

相应的XSD是在这里：

<?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>

我系统地得到一个UnmarshallingFailureException：

您的信息我使用Spring OXM。

我强烈怀疑这与我的XSD架构做，可能命名空间...

任何人都可以请帮助？

编辑：下面是相关的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>

编辑2：异常跟踪，如果我注释掉架构验证：

当您在Spring环境之外运行JAXB时，是否看到相同的异常？ – 2012-07-06 15:14:11

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

你可以发布任何Spring相关的配置吗？ – 2012-07-06 15:49:10

似乎没有成为一个链接是personne元素和Personne类。如果你生成你的模型，你可以尝试改变你的配置使用上下文路径？

<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>

问题是，单个项目是“personne”标签，而不是包含“personnes”标签......请参阅包含的XML。 – balteo 2012-07-06 15:58:28

另请参见[spring批处理参考文档]（http://static.springsource.org/spring-batch/reference/html/readersAndWriters.html#StaxEventItemReader） – balteo 2012-07-06 16:01:29

如果注释掉'。 – 2012-07-06 16:02:23
