Docx4j 6.1.2-将平面开放XML转换为Xlsx

Question

我可以使用以下代码从Xlsx创建一个平面OPC XML文件：

SpreadsheetMLPackage spreadsheetMLPackage = SpreadsheetMLPackage.load(new File("test.xlsx"));
FlatOpcXmlCreator flatOpcXmlCreator = new FlatOpcXmlCreator(spreadsheetMLPackage);
String flatOpcXml = org.docx4j.XmlUtils.marshaltoString(flatOpcXmlCreator.get(), false, true, org.docx4j.jaxb.Context.jcXmlPackage);
Files.write(Path.of("testFlatOpc.xml"), flatOpcXml.getBytes(), StandardOpenOption.CREATE, StandardOpenOption.WRITE);

FlatOpcXmlImporter flatOpcXmlImporter = new FlatOpcXmlImporter(new FileInputStream("testFlatOpc.xml"));
OpcPackage opcPackage = flatOpcXmlImporter.get();

为什么FlatOpcXmlCreator会写入FlatopcXmllimporter无法读取的命名空间？

如果docx4j不可能，那么是否有其他方法可以从平面OPC XML创建Excel？

此问题现已由https://github.com/plutext/docx4j/commit/f5f8b2c9caa9a3d8d339b74e7e878d19c56ad526修复

这将出现在下一个8.1.x版本中，或者您可以自己用该补丁修补6.1.2。
