POI生成word文檔

1:須要的jar包

2：作法  建立一個Java工程-------引入夾包------寫個測試類測試，以下圖大概結構

 

3：類代碼寫法以下，作法：在d盤下放個圖片   例如：D:\\123.jpg  ,  直接建立一個類，把代碼所有粘過去， 運行main方法，看D盤生成的文件

4：生成的效果

 

 

 

 

5:在web項目中controller中的大概寫法，這樣前端直接調用這個方法，就會在頁面上直接下載了

//**********************************開始****************************************

public String exportWord(HttpServletRequest request, HttpServletResponse response) {
        List<Map<String,Object>> dataList = DjOrgTxlDwryServiceImpl.exportWord();//獲取數據,通常是從庫裏查詢的數據，這裏能夠改爲本身造的數據
        if(!ObjectUtils.isEmpty(dataList)){//判斷數據不爲null,而且不爲空
            try {
                XWPFDocument document= WordExport.initDoc(dataList);
                String filename="部門通信錄";
                response.setHeader("Content-Disposition","attachment;filename="+new String(filename.getBytes(), "iso8859-1")+".docx");
                OutputStream out = response.getOutputStream();
                document.write(out);
                out.close();
                return null;
            } catch (IOException e) {
                return "導出數據異常！！！！！";
            }
        }else{
            return "查詢數據爲空，沒有要導出的數據";
        }
    }

 6：在web項目中獲取項目中圖片的寫法

 //========插入圖片===============
XWPFParagraph pictures = document.createParagraph();
pictures.setIndentationLeft(300);//前面縮進300
XWPFRun insertNewRun = pictures.createRun();
int format =XWPFDocument.PICTURE_TYPE_PNG;

try {
 ClassPathResource classPathResource = new ClassPathResource("image/123.png");
 InputStream instream = classPathResource.getInputStream();
 String imgFile = classPathResource.getPath();
 insertNewRun.addPicture(instream, format, imgFile, Units.toEMU(250), Units.toEMU(45)); // 200x200 pixels
} catch (InvalidFormatException e) {
 e.printStackTrace();
} catch (IOException e) { e.printStackTrace();}
