删除部分 XML 声明，encoding="UTF-8" standalone="yes" JAXB

Question

我正在使用 JAXB 拆分传入的 xml 文件。我知道这似乎是一个重复的线程，但是

预期，

<?xml version="1.0"?>

实际，

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

我尝试使用 JAXB_FRAGMENT 完全删除了第一行

jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);

和

jaxbMarshaller.setProperty("com.sun.xml.bind.xmlHeaders", "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>");

有无 Marshaller.JAXB_FRAGMENT

仅供参考，我正在使用 StringWriter

        JAXBContext jaxbContext = JAXBContext.newInstance(ExportDocument.class);
        Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
        jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);//

        //jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);

        //jaxbMarshaller.setProperty("com.sun.xml.bind.xmlHeaders", "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>");

        StringWriter sw = new StringWriter();
        jaxbMarshaller.marshal(employee, sw);
        String xmlContent = sw.toString();

        System.out.println(xmlContent);

我实际上在寻找完全相同的东西，这就是我找到的 Altering the XML header produced by the JAXB marshaller
