如何使用apache poi创建一个简单的docx文件?

apache-poi docx java

guerda · 技术社区 · 15 年前

我正在搜索一个简单的示例代码或完整的教程,如何创建 docx 使用apache poi及其底层的文件 openxml4j 。

我尝试了以下代码很多来自内容辅助的帮助,谢谢Eclipse!)但是代码不能正常工作。

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);

引发的异常如下:

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)

有人能帮我满足我的(非常简单的)要求吗?

以下是如何使用POI创建简单的docx文件:

XWPFDocument document = new XWPFDocument();
XWPFParagraph tmpParagraph = document.createParagraph();
XWPFRun tmpRun = tmpParagraph.createRun();
tmpRun.setText("LALALALAALALAAAA");
tmpRun.setFontSize(18);
document.write(new FileOutputStream(new File("yourpathhere")));
document.close();

    public void newWordDoc(String filename, String fileContent)   
         throws Exception {   
       XWPFDocument document = new XWPFDocument();   
       XWPFParagraph tmpParagraph = document.createParagraph();   
       XWPFRun tmpRun = tmpParagraph.createRun();   
       tmpRun.setText(fileContent);   
       tmpRun.setFontSize(18);   
       FileOutputStream fos = new FileOutputStream(new File("C:\\Users\\amitabh\\Pictures\\pics\\"+filename + ".doc"));   
       document.write(fos);   
       fos.close();   
    }   
    public static void main(String[] args) throws Exception {   
         DocFile app = new DocFile();   
         app.newWordDoc("testfile", "Hi hw r u?");   

    }   
  }
