作者wangsz，想寫一些關于word的工具，所以就寫了這篇文章

1.首先，先導入所需要的依賴（poi相關依賴即可）

<!-- POI --><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml-schemas</artifactId><version>4.1.2</version></dependency><!-- poi-tl --><dependency><groupId>com.deepoove</groupId><artifactId>poi-tl</artifactId><version>1.9.1</version></dependency><!-- https://mvnrepository.com/artifact/org.apache.pdfbox/pdfbox --><dependency><groupId>org.apache.pdfbox</groupId><artifactId>pdfbox</artifactId><version>2.0.24</version></dependency><dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.13</version></dependency><dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.2.0</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency>

2.依賴導入完成后，先了解一些poi基礎知識，制作word模板

{{template}}
普通文本，渲染數據為：String或者TextRenderData

{{@template}}
圖片,渲染數據為：PictureRenderData

{{#template}}
表格，渲染數據為：TableRenderData
{{*template}}
列表，渲染數據為：NumbericRenderData

3.編寫生成word文檔代碼

 //將圖片轉換成字節數組public static byte[] getUrlByteArray(String imageUrl) throws IOException {URL url = new URL(imageUrl);try (InputStream inputStream = url.openStream();ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) {byte[] buffer = new byte[4096];int bytesRead;while ((bytesRead = inputStream.read(buffer)) != -1) {outputStream.write(buffer, 0, bytesRead);}return outputStream.toByteArray();}}
// 主要工具
public void testPicture(){Map<String, Object> datas = new HashMap() {{//本地圖片//     put("photo", new PictureRenderData(100, 116, "C:\\Users\\53129\\Pictures\\Saved Pictures\\111.png") );put("name","王首zhen");//  put("oname","");put("sex","男");put("nation","漢族");put("address","天津市");
//				//本地圖片byte數據
//				put("localBytePicture", new PictureRenderData(100, 120, ".png", BytePictureUtils.getLocalByteArray(new File("src/test/resources/logo.png"))));
//				//網路圖片try {put("photo", new PictureRenderData(100, 100, ".png", testPotPi.getUrlByteArray("https://avatars3.githubusercontent.com/u/1394854?v=3&s=40")));} catch (IOException e) {e.printStackTrace();}
//				// java 圖片
//				put("bufferImagePicture", new PictureRenderData(100, 120, ".png", BytePictureUtils.getBufferByteArray(bufferImage)));}};XWPFTemplate template = XWPFTemplate.compile("C:\\Users\\53129\\Desktop\\模板文件.docx").render(datas);FileOutputStream out;try {out = new FileOutputStream("C:\\Users\\53129\\Desktop\\生成文件.docx");template.write(out);out.flush();out.close();template.close();} catch (FileNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}

4.測試代碼

  public static void main(String[] args) {long l = System.currentTimeMillis();new testPotPi().testPicture();long l1 = System.currentTimeMillis();System.err.println("運行時長"+(l1-l));}

5.封裝工具類

   /*tempath :模板文件地址decPath : 生成文件地址*/public static void testPicture(Map<String, Object> datas , String temPath , String decPath){XWPFTemplate template = XWPFTemplate.compile(temPath).render(datas);FileOutputStream out;try {out = new FileOutputStream(decPath);template.write(out);out.flush();out.close();template.close();} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}
