Thank you. Confirmed that the following does the trick. outputFactory.setProperty(XMLOutputFactory2.P_AUTOMATIC_EMPTY_ELEMENTS, Boolean.FALSE);.

I set the property but it doesn’t work. code :

CorpGoodsReport g = new CorpGoodsReport();
XmlMapper xmlMapper = new XmlMapper();
xmlMapper.getFactory().getXMLOutputFactory().setProperty(WstxOutputProperties.P_AUTOMATIC_END_ELEMENTS, false);
xmlMapper.enable(SerializationFeature.INDENT_OUTPUT);
xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_DECLARATION, true);
xmlMapper.writeValue(new FileOutputStream("a.xml"), g);

But if field is null ,the xml tag will be <FIELD_CHAR3/> ，if field is “” ,XmlMapper can generate normally
<FIELD_CHAR1></FIELD_CHAR1>. Do you have any idea can fix it?
