POI根据模板导出word文件

一、制作word模版,${xxxx}是一会要替换的内容,最下面的表格是要插入数据,根据是否以$开头来判断是需要替换还是插入数据。
????????注意如果是需要插入数据,制作的表格模版需要一行空行,也只能有一行空行,原因可以看代码的逻辑,表格中${header}${hearder2}是放入需要替换的图片
技术图片
二、添加poi所需要的jar包文件,我用的maven对jar包进行管理

<dependency>
     <groupId>org.apache.poi</groupId>
     <artifactId>poi</artifactId>
     <version>3.11</version>
</dependency>
<dependency>
     <groupId>org.apache.poi</groupId>
     <artifactId>poi-ooxml</artifactId>
     <version>3.11</version>
</dependency>

三、由于poi自身bug,会出现图片无法显示问题,这里需要自定义一个类继承XWPFDocument类,接下来使用的都是我们自己创建的这个类来操作word对象,这个类对XWPFDocument进行了继承,所以不用担心会有什么问题

import java.io.InputStream;

import org.apache.poi.openxml4j.opc.OPCPackage;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.xmlbeans.XmlException;
import org.apache.xmlbeans.XmlToken;
import org.openxmlformats.schemas.drawingml.x2006.main.CTNonVisualDrawingProps;
import org.openxmlformats.schemas.drawingml.x2006.main.CTPositiveSize2D;
import org.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTInline;

public class CustomXWPFDocument extends XWPFDocument {

   public CustomXWPFDocument(InputStream in) throws java.io.IOException {
           super(in);
   }

   public CustomXWPFDocument() {
           super();
   }

   public CustomXWPFDocument(OPCPackage pkg)throws java.io.IOException {
           super(pkg);
   }

   /**
    * @param id
    * @param width 宽
    * @param height 高
    * @param paragraph  段落
    */
   public void createPicture(int id, int width, int height,XWPFParagraph paragraph) {
   final int EMU = 9525;
   width *= EMU;
   height *= EMU;
   String blipId = getAllPictures().get(id).getPackageRelationship().getId();
   CTInline inline = paragraph.createRun().getCTR().addNewDrawing().addNewInline();
   String picXml = ""
   +"<a:graphic xmlns:a=\"http://schemas.openxmlformats.org/drawingml/2006/main\">"
   +"   <a:graphicData uri=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">"
   +"      <pic:pic xmlns:pic=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">"
   +"         <pic:nvPicPr>" + "            <pic:cNvPr id=\""
   + id
   +"\" name=\"Generated\"/>"
   +"            <pic:cNvPicPr/>"
   +"         </pic:nvPicPr>"
   +"         <pic:blipFill>"
   +"            <a:blip r:embed=\""
   + blipId
   +"\" xmlns:r=\"http://schemas.openxmlformats.org/officeDocument/2006/relationships\"/>"
   +"            <a:stretch>"
   +"               <a:fillRect/>"
   +"            </a:stretch>"
   +"         </pic:blipFill>"
   +"         <pic:spPr>"
   +"            <a:xfrm>"
   +"               <a:off x=\"0\" y=\"0\"/>"
   +"               <a:ext cx=\""
   + width
   +"\" cy=\""
   + height
   +"\"/>"
   +"            </a:xfrm>"
   +"            <a:prstGeom prst=\"rect\">"
   +"               <a:avLst/>"
   +"            </a:prstGeom>"
   +"         </pic:spPr>"
   +"      </pic:pic>"
   +"   </a:graphicData>" + "</a:graphic>";

   inline.addNewGraphic().addNewGraphicData();
   XmlToken xmlToken = null;
   try{
   xmlToken = XmlToken.Factory.parse(picXml);
   }catch(XmlException xe) {
   xe.printStackTrace();
   }
   inline.set(xmlToken);

   inline.setDistT(0);
   inline.setDistB(0);
   inline.setDistL(0);
   inline.setDistR(0);

   CTPositiveSize2D extent = inline.addNewExtent();
   extent.setCx(width);
   extent.setCy(height);

   CTNonVisualDrawingProps docPr = inline.addNewDocPr();
   docPr.setId(id);
   docPr.setName("图片"+ id);
   docPr.setDescr("测试");
   }
}

四、接下来就是导出word的工具类了

import java.io.*;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

import javax.servlet.http.HttpServletResponse;

import org.apache.poi.xwpf.usermodel.*;
import org.springframework.stereotype.Component;

       File file = new File(path);
       InputStream is = new FileInputStream(file);
       CustomXWPFDocument doc = new CustomXWPFDocument(is);
       this.replaceInPara(doc, params); // 替换文本里面的变量
       this.replaceInTable(doc, params, tableList); // 替换表格里面的变量

       OutputStream os = new FileOutputStream(newFile);
       doc.write(os);
       this.close(os);
       this.close(is);

       return outFileName;
   }

   /**

五、最后就是进行测试了,我是用的是ssm框架,这里放出测试代码

@RequestMapping("exportWordData")
   public void exportWordData(HttpServletRequest request,HttpServletResponse response){
       WordUtils wordUtil=new WordUtils();

       params.put("${xueLi}", "本科");
       params.put("${school}", "江西科技师范大学");
       params.put("${phone}", "177");
       params.put("${eMail}", "157");

       try{
           Map<String,Object> header = new HashMap<String, Object>();
           header.put("width", 100);
           header.put("height", 150);
           header.put("type", "jpg");
           header.put("content", WordUtils.inputStream2ByteArray(new FileInputStream("C:/Users/Administrator/Desktop/jar包/11.jpg"), true));
           params.put("${header}",header);
           Map<String,Object> header2 = new HashMap<String, Object>();
           header2.put("width", 100);
           header2.put("height", 150);
           header2.put("type", "jpg");
           header2.put("content", WordUtils.inputStream2ByteArray(new FileInputStream("C:/Users/Administrator/Desktop/jar包/22.jpg"), true));
           params.put("${header2}",header2);       
           List<List<String[]>> list = new ArrayList<List<String[]>>();
           List<String[]> testList = new ArrayList<String[]>();//一个需要插入的表是一个集合
           testList.add(new String[]{"1","1AA","1BB","1CC"});
           testList.add(new String[]{"2","2AA","2BB","2CC"});
           testList.add(new String[]{"3","3AA","3BB","3CC"});
           testList.add(new String[]{"4","4AA","4BB","4CC"});       list.add(testList);
           String path="C:/Users/Administrator/Desktop/jar包/mobanFile.docx";  //模板文件位置
           String fileName= new String("测试文档.docx".getBytes("UTF-8"),"iso-8859-1");    //生成word文件的文件名
           wordUtil.getWord(path,params,list,fileName,newFilePath);

       }catch(Exception e){
           e.printStackTrace();

word转PDF

WORD转PDF所需jar包:

PDF转图片所需jar包:

word转pdf使用的是ASPOSE.word,它的licence需要收费,百度有的文章中有,大家可以自行百度,这里就不放了。调用时传入word的路径和生成后的pdf的路径就行。
注意:在linux下不可以直接FileOutputSteram(path)生成文件,所以需要先new File(path),如果生成之后的文件中文乱码,可能是服务器没有字库,安装一个就可以了

package com.biolims.report.service;

import java.io.FileOutputStream;
import java.io.InputStream;

import com.aspose.words.Document;
import com.aspose.words.License;
import com.aspose.words.SaveFormat;

/**
 * 
 * 由于ASPOSE比较吃内存,操作大一点的文件就会堆溢出,所以请先设置好java虚拟机参数:-Xms512m -Xmx512m(参考值)<br>
 * 如有疑问,请在CSDN下载界面留言,或者联系QQ569925980<br>

PDF转图片再插入PDF中(防止PDF被修改)

公司大佬说这种防止修改的方法在pdf有多页时可能会出问题,也没测试过,试过的朋友帮忙评论一下

public static String pdf2Image(String PdfFilePath) throws Exception {
        File file = new File(PdfFilePath);
        PdfDocument template_writer_pdfdoc = new PdfDocument(new PdfReader(PdfFilePath));
        Rectangle size=template_writer_pdfdoc.getFirstPage().getPageSize();
        int pages = template_writer_pdfdoc.getNumberOfPages();
        PDDocument pdDocument;
        String pdfPath="";
        try {
            String imgPDFPath = file.getParent();
            int dot = file.getName().lastIndexOf(‘.‘);
            String imagePDFName = file.getName().substring(0, dot); // 获取图片文件名
            pdDocument = PDDocument.load(file);
            PDFRenderer renderer = new PDFRenderer(pdDocument);
            /* dpi越大转换后越清晰,相对转换速度越慢 */
            StringBuffer imgFilePath = null;
            List<String> pathList=new ArrayList<String>();
            for (int i = 0; i < pages; i++) {
                String imgFilePathPrefix = imgPDFPath + File.separator + imagePDFName;
                imgFilePath = new StringBuffer();
                imgFilePath.append(imgFilePathPrefix);
                imgFilePath.append("_");
                imgFilePath.append(String.valueOf(i + 1));
                imgFilePath.append(".jpg");
                File dstFile = new File(imgFilePath.toString());
                BufferedImage image = renderer.renderImageWithDPI(i, 300);
                ImageIO.write(image, "jpg", dstFile);
                pathList.add(imgFilePath.toString());
            }

            template_writer_pdfdoc.close();
            File file2 = new File(imgPDFPath + File.separator + file.getName());
            // 第一步:创建一个document对象。
            com.itextpdf.text.Document document = new com.itextpdf.text.Document();
            document.setMargins(0, 0, 0, 0);
            // 第二步:
            // 创建一个PdfWriter实例,
            com.itextpdf.text.pdf.PdfWriter.getInstance(document, new FileOutputStream(file2));
            // 第三步:打开文档。

            document.open();
            for(String s:pathList) {
                com.itextpdf.text.Image img = com.itextpdf.text.Image.getInstance(s);
                img.setAlignment(com.itextpdf.text.Image.ALIGN_CENTER);
                img.scaleAbsoluteHeight(size.getHeight());
                img.scaleAbsoluteWidth(size.getWidth());
                // 根据图片大小设置页面,一定要先设置页面,再newPage(),否则无效
                document.setPageSize(new com.itextpdf.text.Rectangle(size.getWidth(), size.getHeight()));
                document.newPage();
                document.add(img);
            }
            document.close();
            pdfPath=imgPDFPath + File.separator + file.getName();
        } catch (IOException e) {
            e.printStackTrace();
        }finally {

        }
        return pdfPath;
    }

POI根据模板导出word文件,以及word转PDF,PDF转图片再插入PDF中(防止PDF被修改)
