java - 从序列化中排除某些对象字段

Question

我正在使用 javax.xml.bind.annotation.XmlRootElement 带注释的对象将其序列化为 xml 字符串。

        JAXBContext jc = JAXBContext.newInstance(obj.getClass());
        // Marshal the object to a StringWriter
        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
        marshaller.setProperty(Marshaller.JAXB_SCHEMA_LOCATION, "http://www.example.com/schema.xsd");
        StringWriter stringWriter = new StringWriter();
        marshaller.marshal(obj, stringWriter);
        result = stringWriter.toString();

如何排除对象的某些字段以便不发送它们？该类字段必须注释什么注释才能将其从最终字符串中排除。

使用@XmlTransient注释:

Prevents the mapping of a JavaBean property/type to XML representation.

@XmlTransient
public String toBeSkippedField;
