使用POI API添加脚注到Word [英] Adding footer to ms word using POI api

问题描述

我搜索了很多，得到了一些结果，其中一些样本code是有，但没有人在工作。所有要么让空指针异常，或者在打开文件（.DOCX）给错误和显示信息的时间生成的文档，然后
可能只在innput的最开始出现的文本/ XML声明。

I searched a lot and getting some results in which some sample code is there but no one is working. All are either getting null pointer exception or if document is generated then at the time of opening file (.docx) giving error and displaying message A text/xml declaration may occur only at the very beginning of innput.

我想可能是我加入了一些内容，然后添加页脚给予一定的问题，所以我贴我的页脚code。在现在一开始这段时间我正在

I thought may be I am adding some content and then adding footer is giving some problem so I pasted my footer code at very beginning now this time I am getting

索引超出边界的异常

下面是我的完整code

Here is my complete code

String fileName ="Book.docx";
String   folderPath=SystemProperties.get(SystemProperties.TMP_DIR)+File.separator+"liferay" + File.separator    + "document_preview";
String filePath=folderPath+File.separator+fileName;
File file=new File(filePath);
XWPFDocument document = new XWPFDocument();  
XWPFParagraph paragraphOne = document.createParagraph();
paragraphOne.setAlignment(ParagraphAlignment.CENTER);
XWPFRun paragraphOneRunOne = paragraphOne.createRun();
paragraphOneRunOne.setText("Training Report");
paragraphOneRunOne.addBreak();
XWPFTable table = document.createTable();
XWPFTableRow tableRowOne = table.getRow(0);
tableRowOne.getCell(0).setText("No");
tableRowOne.createCell().setText("Name");
XWPFHeaderFooterPolicy headerFooterPolicy = document.getHeaderFooterPolicy();
            if (headerFooterPolicy == null) {
                CTBody body = document.getDocument().getBody();
                CTSectPr sectPr = body.getSectPr();
                if (sectPr == null) {
                sectPr = body.addNewSectPr();
                }
                headerFooterPolicy = new XWPFHeaderFooterPolicy(document, sectPr);
                }
            CTP ctP1 = CTP.Factory.newInstance();
            CTR ctR1 = ctP1.addNewR();
            CTText t = ctR1.addNewT();
            t.setStringValue("first footer");
            XWPFParagraph codePara = new XWPFParagraph(ctP1);
            XWPFParagraph[] newparagraphs = new XWPFParagraph[1];
            newparagraphs[0] = codePara;
             XWPFFooter xwpfFooter = null;
    xwpfFooter =  headerFooterPolicy.createFooter(XWPFHeaderFooterPolicy.DEFAULT);
 FileOutputStream fileoutOfTraining = new FileOutputStream(file);
            document.write(fileoutOfTraining);
            fileoutOfTraining.flush();
            fileoutOfTraining.close();
   downloadOperation(file, fileName, resourceResponse);

code在downloadOperation方法

code in downloadOperation method

HttpServletResponse httpServletResponse =PortalUtil.getHttpServletResponse(resourceResponse);
BufferedInputStream input = null;
        BufferedOutputStream output = null;
 httpServletResponse.setHeader("Content-Disposition", "attachment;    filename=\""+fileName+"\"; filename*=UTF-8''"+fileName);
int  DEFAULT_BUFFER_SIZE=1024;
        try {
            input = new BufferedInputStream(new FileInputStream(file), DEFAULT_BUFFER_SIZE);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        try {
            resourceResponse.flushBuffer();
            output = new BufferedOutputStream(httpServletResponse.getOutputStream(), DEFAULT_BUFFER_SIZE);
        } catch (IOException e) {
            e.printStackTrace();
        }
byte[] buffer = new byte[2*DEFAULT_BUFFER_SIZE];
        int length;
        try {
            while ((length = input.read(buffer)) > 0) {
                output.write(buffer, 0, length);
            }
            output.flush();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                output.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

请帮我产生页脚，这是我的code，如果我在我的段落和表则没有运行时错误，但在开幕生成的文件错误后添加脚注$ C​​ $ C，如果我之前放置的页脚处我想在文档中，然后我得到错误索引超出边界的异常增加内容。
如果有任何code片段或朝向解决至少某些指针任何一个请帮助我。
谢谢

Please help me to generate footer, this is my code, if I add footer code after my paragraph and table then no run time error but error in opening generated file, if I placed footer at before the contents that I want to add in documents then I am getting error "index out of bound exception". Please help me if any one having any code snippet or at least some pointers towards the solution. Thanks

推荐答案

我面对这个问题，解决的办法是
我们必须使用3.10最终POI罐子。
3.9有这个问题。
请删除的previous版本罐子，并添加3.10在这个bug是固定的最终版本罐子。
罐子都需要
1. POI-3.10-FINAL.jar
2. POI-OOXML-3.10-FINAL.jar
3. POI-OOXML-架构 - 3.10 - FINAL.jar
净容易获得。
http://mvnrepository.com/artifact/org.apache.poi/poi /3.10-FINAL

I faced this issue and the solution is We have to use 3.10 final poi jar. 3.9 having this problem. Please remove jars of previous version and add jars of 3.10 final version in which this bug is fixed. jars requires are 1. poi-3.10-FINAL.jar 2. poi-ooxml-3.10-FINAL.jar 3. poi-ooxml-schemas-3.10-FINAL.jar Easily available in net. http://mvnrepository.com/artifact/org.apache.poi/poi/3.10-FINAL

XWPFDocument document = new XWPFDocument();
CTP ctp = CTP.Factory.newInstance();
CTR ctr = ctp.addNewR();
CTRPr rpr = ctr.addNewRPr();
CTText textt = ctr.addNewT();
textt.setStringValue( " Page 1" );
XWPFParagraph codePara = new XWPFParagraph( ctp, document );
XWPFParagraph[] newparagraphs = new XWPFParagraph[1];
newparagraphs[0] = codePara;
CTSectPr sectPr = document.getDocument().getBody().addNewSectPr();
XWPFHeaderFooterPolicy headerFooterPolicy = new  XWPFHeaderFooterPolicy( document, sectPr );
headerFooterPolicy.createFooter( STHdrFtr.DEFAULT, newparagraphs );

以上code为正常使用，请使用3.10战争那些我上面提到的。

The above code is working perfectly, please use 3.10 wars those I mentioned above.
