## 导出doc，使用itext： ##

pom.xml中加入：

<dependency>
        <groupId>com.lowagie</groupId>
        <artifactId>itext</artifactId>
        <version>2.1.7</version>
    </dependency>
    
    <dependency>
        <groupId>com.lowagie</groupId>
        <artifactId>itext-rtf</artifactId>
        <version>2.1.7</version>
    </dependency>

代码：

public static void main(String[] args){
        String outPath+"D:/test.doc";
        Document document = new Document(PageSize.A4, 36, 72, 108, 120);
        File file=new File(outPath);
        RtfWriter2.getInstance(document,new FileOutputStream(file));
        document.open();
        createParagraph(document, "xxx");
        File file = new File("D:/img1.png");
        BufferedImage buffeImage = ImageIO.read(file);
        insertImgByAlign(document, file.getPath(), 0, buffeImage.getHeight(), buffeImage.getWidth());
        document.close();
        File file = new File(outPath);
        response.setHeader("Content-Type", "application/msword");
        String fileName = WebUtil.encodeDownloadFileName(file.getName());
        response.setHeader("Content-Disposition", "attachment;filename=" + fileName);
        WebUtil.writeFileToResponse(response, file);
    }
    private void createParagraph(Document document, String text) throws DocumentException, MalformedURLException, IOException{
        Paragraph bh = new Paragraph(text);
        bh.setAlignment(Element.ALIGN_LEFT);
        getImageAligns(text, document);
    }
    /* * 插入图片如果在这里修改长和宽，图片的大小还是原来的大小，所以最好先设置图片合适的大小，再插入 * @param document 文档对象 * @param imgUrl 图片路径 * @param imageAlign 显示位置 * @param height 显示高度 * @param weight 显示宽度 * @throws MalformedURLException * @throws IOException * @throws DocumentException */  
    public void insertImgByAlign(Document document,String imgUrl,int imageAlign,int height,
    int weight) throws MalformedURLException, IOException, DocumentException{  
        Image img = Image.getInstance(imgUrl);
        if(img==null)  
            return;  
        img.setAlignment(imageAlign);  
        img.scaleAbsolute(weight,height);  
        document.add(img);
    }

### 导出docx ###

用poi来实现：

XWPFDocument doc = new XWPFDocument();
    XWPFParagraph citiaoP = doc.createParagraph();
    XWPFRun citiaoR = citiaoP.createRun();
    citiaoR.setText("text");
    try {
        FileOutputStream out = new FileOutputStream(outPath);
            doc.write(out);
        out.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    File file = new File(outPath);
    response.setHeader("Content-Type", "application/msword");
    String fileName = WebUtil.encodeDownloadFileName(file.getName());
    response.setHeader("Content-Disposition", "attachment;filename=" + fileName);
    WebUtil.writeFileToResponse(response, file);
