openoffice将word转成pdf及添加水印

系统维护需求，需要将word转成pdf，上一篇博客是把word2003的模板升级成word2007模板，因为旧模板生成的word为xml格式转成pdf后内容不对，在网上搜寻了很久linux系统相关支持，发现了openoffice4.
参考：openoffice安装和卸载

启动openoffice
linux下：

cd /opt/openoffice4/program 

 ./soffice "-accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager" -nologo -headless -nofirststartwizard &

查看是否启动
ps -ef | grep openoffice
贴上部分java代码word转成pdf

 public  boolean officeToPDF(String sourceFile, String destFile) {
		        try {

		            File inputFile = new File(sourceFile);
		           // Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(inputFile), "UTF-8")); 
		            
		            if (!inputFile.exists()) {
		                // 找不到源文件, 则返回false
		                return false;
		            }
		            // 如果目标路径不存在, 则新建该路径
		            File outputFile = new File(destFile);
		            if (!outputFile.getParentFile().exists()) {
		                outputFile.getParentFile().mkdirs();
		            }
		            //如果目标文件存在，则删除
		            if (outputFile.exists()) {
		                outputFile.delete();
		            }
		            
		            
/*		            Document document = new Document();
		            document.loadFromFile("Sample.docx");
		            //保存结果文件
		            document.saveToFile("out/toPDF.pdf", FileFormat.PDF);*/
		            DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm");
		            OpenOfficeConnection connection = new SocketOpenOfficeConnection("127.0.0.1", 8100);
		            connection.connect();
		            //用于测试openOffice连接时间
		            System.out.println("连接时间:" + df.format(new Date()));
		            //DocumentConverter converter = new OpenOfficeDocumentConverter(connection);
		            DocumentConverter converter = new StreamOpenOfficeDocumentConverter(connection);

		            converter.convert(inputFile, outputFile);
		            //测试word转PDF的转换时间
		            System.out.println("转换时间:" + df.format(new Date()));
		            connection.disconnect();
		            return true;
		        } catch (Exception e) {
		            e.printStackTrace();
		            System.err.println("openOffice连接失败！请检查IP,端口");
		        } 
		        return false;
		    }

iText相关添加图片或者文字水印功能

 public static void setWatermark(BufferedOutputStream bos, String input, String waterMarkName, int permission)
     throws DocumentException, IOException {
			 PdfReader reader = new PdfReader(input);
			 PdfStamper stamper = new PdfStamper(reader, bos);
			 int total = reader.getNumberOfPages() + 1;
			 PdfContentByte content;
			 BaseFont base = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.EMBEDDED);
			 PdfGState gs = new PdfGState();
			 for (int i = 1; i < total; i++) {
			    // content = stamper.getOverContent(i);// 在内容上方加水印
			     content = stamper.getUnderContent(i);//在内容下方加水印
			     gs.setFillOpacity(0.2f);
			     // content.setGState(gs);
			     content.beginText();
			     content.setColorFill(Color.LIGHT_GRAY);
			     content.setFontAndSize(base, 50);
			     content.setTextMatrix(70, 200);
			    // content.showTextAligned(Element.ALIGN_CENTER, "公司内部文件，请注意保密！", 300, 350, 55);
			     Image image = Image.getInstance(ProjectEnv.getWebappPath()+"/0001.jpg");
			     /*
			       img.setAlignment(Image.LEFT | Image.TEXTWRAP);
			       img.setBorder(Image.BOX); img.setBorderWidth(10);
			       img.setBorderColor(BaseColor.WHITE); img.scaleToFit(100072);//大小
			       img.setRotationDegrees(-30);//旋转
			      */
			     image.setAbsolutePosition(0, 0); // set the first background
			                                             // image of the absolute
			     image.scaleToFit(850, 850);
			     content.addImage(image);
			     content.setColorFill(Color.BLACK);
			   //  content.setFontAndSize(baase, 8);
			    // content.showTextAligned(Element.ALIGN_CENTER, "下载时间：" + waterMarkName + "", 300, 10, 0);
			     content.endText();
			
			 }
			 stamper.close();
		}

再贴一段代码，pdf拼接用

public static boolean mergePdfFiles(String[] files, String newfile) {
        boolean retValue = false;
        Document document = null;
        try {
            document = new Document(new PdfReader(files[0]).getPageSize(1));
            PdfCopy copy = new PdfCopy(document, new FileOutputStream(newfile));
            document.open();
            for (int i = 0; i < files.length; i++) {
                PdfReader reader = new PdfReader(files[i]);
                int n = reader.getNumberOfPages();
                for (int j = 1; j <= n; j++) {
                    document.newPage();
                    PdfImportedPage page = copy.getImportedPage(reader, j);
                    copy.addPage(page);
                }
            }
            retValue = true;
        } catch (Exception e) {
            System.out.println(e);
        } finally {
            System.out.println("合并执行结束");
            document.close();
        }
        return retValue;
    }
