Java 在响应中设置XML头

我有两个通过Jersey/Jaxb实现的web服务，它们以

<?xml version="1.0" encoding="UTF-8"?> 

---

有没有更好的方法来实现它

？^这不能回答我的问题

@Provider
public class JaxbMarshallerResolver implements ContextResolver<Marshaller> 
{

    @Override
    public Marshaller getContext(Class<?> type) 
    {
        Marshaller marshaller;
        try
        {
            JAXBContext jc = JAXBContext.newInstance(type);
            marshaller = jc.createMarshaller();
            marshaller.setProperty("com.sun.xml.bind.xmlDeclaration", Boolean.FALSE);
            marshaller.setProperty("com.sun.xml.bind.xmlHeaders", "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>");
        }
        catch (JAXBException je)
        {
            throw new RuntimeException(je);
        }
        return marshaller;
    }
}
