Answer 1

当从 XML 模式生成 JAXB 模型时，我始终建议使用生成的模型的包名创建 JAXBContext。

JAXBContext jc = JAXBContext.newInstance("org.w3._2004._08.xop.include");

您没有指定要部署到 GlassFish 的应用程序类型，但如果它是 JAX-RS/Jersey 应用程序，我建议使用 ContextResolver。这是一种标准机制，可让您更好地控制JAXBContext 的创建方式。下面是一个例子。

import java.util.*;
import javax.ws.rs.Produces;
import javax.ws.rs.ext.*;
import javax.xml.bind.*;
import org.eclipse.persistence.jaxb.JAXBContextFactory;

@Provider
@Produces({"application/xml", "application/json"})
public class SampleContextResolver implements ContextResolver<JAXBContext> {

    private JAXBContext jc;

    public SampleContextResolver() {
        try {
            jc = JAXBContext.newInstance("org.w3._2004._08.xop.include");
        } catch(JAXBException e) {
            throw new RuntimeException(e);
        }
    }

    public JAXBContext getContext(Class<?> clazz) {
        if(clazz.getPackage().getName().equals("org.w3._2004._08.xop.include")) {
            return jc;
        }
        return null;
    }

}

Answer 2

我在 6 个月前遇到了完全相同的问题，老实说，我不记得它是如何解决的（可能我们不需要某些功能，所以我们把它放在一边）。但是今天我们可爱的堆栈跟踪再次被消息诅咒（字面上就像你的一样）

但这一次我能够应付。

Include 类没有任何问题。但不知何故，这是我的猜测，它没有为 jaxb 正确加载，或者在我们需要它的时候没有加载，或者......无论如何。

我试图在我的代码中做的是验证肥皂消息的有效负载。

    JAXBContext jaxbContext = JAXBContext.newInstance(UnifoTransferMsg.class) ;
    SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
    Schema schema = schemaFactory.newSchema(new File("UnifoTransferMsg.xsd"));

    Marshaller marshaller = jaxbContext.createMarshaller();
    marshaller.setSchema(schema);
    marshaller.marshal(inputmsg, System.out);

为我提供硬编码值，它只是用于调试。尽管如此，第一行是引发异常的地方，因为 Jaxb 不知何故对 Include 一无所知或使用了错误的类。要修复它，需要在同一个调用中加载多个类。

所以对我来说最终的解决办法是

JAXBContext.newInstance(Include.class, UnifoTransferMsg.class);

希望对您有所帮助，也许有一天我会详细说明问题的真正原因。

您可以尝试将@XmlRoolElement 注解放在生成包含类上。
