使用XStream的自闭标签?

PrettyPrintWriter 类,这可能是它正在使用的。

特别是XStream只为非基元对象打印自闭标签;因此,我将所有String对象替换为一个名为“Element”的泛型类,该类只有一个属性“value”。

public class Element {
    private String value;
    public Element() {
    }
    public Element(String value) {
        this.value = value;
    }
    public String getValue() {
        return value;
    }
    public void setValue(String value) {
        this.value = value;
    }
}

public class CustomElementConverter implements Converter
{
    public boolean canConvert(Class type)
    {
        return type.equals(Element.class);
    }
    public void marshal(Object source, HierarchicalStreamWriter writer, MarshallingContext context) {
        String element = ((Element)source).getValue();
        if (element != null) { 
            writer.setValue(element);
        }
    }
    public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context) {
        return null;
    }
}

我希望它对别人有用。

Dom

这样地:

public void marshal(Object source, HierarchicalStreamWriter writer, MarshallingContext context) {
    Ack ack = (Ack)source;

    writeBasicAck(writer, ack);

    writer.setValue("");
}

protected void writeBasicAck(HierarchicalStreamWriter writer, Ack ack) {
    writer.addAttribute("pos", String.valueOf(ack.getPos()));
    writer.addAttribute("ticket", String.valueOf(ack.getTicket()));
    writer.addAttribute("estado", String.valueOf(ack.getEstado()));
    writer.addAttribute("suc", String.valueOf(ack.getSucursal()));
}

这写:

<ackticket pos="2" ticket="123" estado="0" suc="1235"></ackticket>

而不是:

<ackticket pos="2" ticket="123" estado="0" suc="1235"/>
