Question

我希望我的Eclipselink 2.3 Marshaller在编组时执行验证。我已确保Schema正确创建SchemaFactory，我将其传递给Marshaller.setSchema，并通过Marshaller.setEventHandler()注册了处理程序。

元帅的结果显然无效。对于它的Schema（在Eclipse中验证），但我可以看到handleEvent(ValidationEvent event)中的断点从未被击中。

我使用marshal(Object, XMLStreamWriter)编组XML片段，并希望Marshaller根据我传递的Schema对这些片段进行验证。

有人知道为什么没有发生这种情况吗？

修改：

应该发生的验证错误：2元素上缺少属性。

该元素对应于List＆lt;＆gt;中包含的Java对象。我使用：

编组列表

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

元素本身的映射：

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

因此，所有属性都被编组到ListWrapperElement / ListElement / @属性。其中2个丢失，未通过验证检测到。

我无法重现您所看到的问题。以下是我的尝试（改编自以下博客文章）：

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);
    }

}
