How can I create a simple docx file with Apache POI?
提问by guerda
I'm searching for a simple example code or a complete tutorial how to create a docxfile with Apache POI and its underlying openxml4j.
我正在寻找一个简单的示例代码或完整的教程，如何docx使用 Apache POI 及其底层openxml4j.
I tried the following code (with a lotof help from the Content Assist, thanks Eclipse!) but the code does not work correctly.
我尝试了以下代码（在 Content Assist的大量帮助下，感谢 Eclipse！）但代码无法正常工作。
String tmpPathname = aFilename + ".docx";
File tmpFile = new File(tmpPathname);
ZipPackage tmpPackage = (ZipPackage) OPCPackage.create(tmpPathname);
PackagePartName tmpFirstPartName = PackagingURIHelper.createPartName("/FirstPart");
PackagePart tmpFirstPart = tmpPackage.createPart(tmpFirstPartName, "ISO-8859-1");
XWPFDocument tmpDocument = new XWPFDocument(tmpPackage); //Exception
XWPFParagraph tmpParagraph = tmpDocument.createParagraph();
XWPFRun tmpRun = tmpParagraph.createRun();
tmpRun.setText("LALALALAALALAAAA");
tmpRun.setFontSize(18);
tmpPackage.save(tmpFile);
The thrown exception is the following:
抛出的异常如下：
Exception in thread "main" java.lang.NullPointerException
at org.apache.poi.POIXMLDocumentPart.read(POIXMLDocumentPart.java:235)
at org.apache.poi.POIXMLDocument.load(POIXMLDocument.java:196)
at org.apache.poi.xwpf.usermodel.XWPFDocument.<init>(XWPFDocument.java:94)
at DocGenerator.makeDocxWithPoi(DocGenerator.java:64)
at DocGenerator.main(DocGenerator.java:50)
Does anybody can help me with my (really simple) requirements?
