JAXB-ElipseLink：Marshaller未验证

Question

我希望我的Eclipselink 2.3 Marshaller在编组时执行验证。 我确定Schema是由SchemaFactory正确创建的，我将它传递给Marshaller.setSchema，并且我通过Marshaller.setEventHandler()注册了一个处理程序。

元帅的结果显然无效。到其Schema（在Eclipse中验证），但我可以看到我的断点handleEvent(ValidationEvent event)从未被击中。

我正在使用marshal(Object, XMLStreamWriter)对XML-Fragments进行编组，并希望Marshaller根据我传递的Schema对这些片段执行验证。

任何人有任何想法，为什么这不会发生？

EDIT：

验证错误应该发生的是：2点的元件上缺少的属性。

该元素对应于包含在列表<>中的Java对象。我编组使用List：

<java-type name="foo.ElementType" xml-accessor-type="PROPERTY"> 
    <java-attributes> 
     // just <xml-attribute> elements here 
    </java-attributes> 
</java-type> 

因此，所有的属性都整理到ListWrapperElement/ListElement/@属性：

<xml-element java-attribute="listInstance" xml-path="ListWrapperElement/ListElement" type="foo.ElementType" container-type="java.util.ArrayList"/> 

的元素本身的映射。 其中2个缺失，未通过验证检测到。

我一直无法重现您所看到的问题。下面是我曾尝试（改编自后续的博客文章）：

MarshalDemo（改编自博客文章）

import java.io.File; 
import javax.xml.XMLConstants; 
import javax.xml.bind.JAXBContext; 
import javax.xml.bind.Marshaller; 
import javax.xml.stream.XMLOutputFactory; 
import javax.xml.stream.XMLStreamWriter; 
import javax.xml.validation.Schema; 
import javax.xml.validation.SchemaFactory; 

import org.eclipse.persistence.Version; 

public class MarshalDemo { 

    public static void main(String[] args) throws Exception { 
     Customer customer = new Customer(); 
     customer.setName("Jane Doe"); 
     customer.getPhoneNumbers().add(new PhoneNumber()); 
     customer.getPhoneNumbers().add(new PhoneNumber()); 
     customer.getPhoneNumbers().add(new PhoneNumber()); 

     SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); 
     Schema schema = sf.newSchema(new File("src/blog/jaxb/validation/customer.xsd")); 

     JAXBContext jc = JAXBContext.newInstance(Customer.class); 
     System.out.println(jc.getClass()); 
     System.out.println(Version.getVersion()); 

     Marshaller marshaller = jc.createMarshaller(); 
     marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); 
     marshaller.setSchema(schema); 
     marshaller.setEventHandler(new MyValidationEventHandler()); 
     XMLStreamWriter xsw = XMLOutputFactory.newFactory().createXMLStreamWriter(System.out); 
     marshaller.marshal(customer, xsw); 
    } 

} 

输出
