一、准备好模板

二、构架项目

1、pom依赖、注意aspose-words依赖官网收费可能拉不下来，需要私聊

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.7.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.pdf</groupId><artifactId>WordTransfromPdf</artifactId><version>0.0.1-SNAPSHOT</version><name>WordTransfromPdf</name><description>WordTransfromPdf</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>com.itextpdf.tool</groupId><artifactId>xmlworker</artifactId><version>5.5.12</version></dependency><dependency><groupId>org.bouncycastle</groupId><artifactId>bcprov-jdk15on</artifactId><version>1.69</version></dependency><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.7.22</version></dependency><dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.12</version></dependency><dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.2.0</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>4.1.2</version></dependency><dependency><groupId>com.deepoove</groupId><artifactId>poi-tl</artifactId><version>1.10.4</version></dependency><dependency><groupId>commons-io</groupId><artifactId>commons-io</artifactId><version>2.8.0</version></dependency><dependency><groupId>fakepath</groupId><artifactId>aspose-words</artifactId><version>20.4</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency><dependency><groupId>org.xhtmlrenderer</groupId><artifactId>flying-saucer-pdf-itext5</artifactId><version>9.1.20</version><exclusions><exclusion><artifactId>itextpdf</artifactId><groupId>com.itextpdf</groupId></exclusion></exclusions></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

2、构建Controller


/*** @author kc* @date Create in  2022/10/26*/
@RestController
public class PdfController {@Autowiredprivate PdfService  pdfService;@RequestMapping("/downloadPdf")@ResponseBodypublic void downloadPreapprovalPdf( HttpServletResponse response) throws UnsupportedEncodingException {String pdfFileName = LocalDateTimeUtil.format(LocalDateTimeUtil.now(), "yyyyMMddHHmmss");response.setContentType("application/pdf");response.setHeader("Access-Control-Allow-Origin", "*");response.setHeader("Access-Control-Allow-Headers", "content-type,x-requested-with,Authorization");response.setHeader("Access-Control-Expose-Headers", "Authorization,authenticated");response.setHeader("Access-Control-Allow-Methods", "GET, POST, PATCH, PUT, OPTIONS");response.setHeader("Access-Control-Allow-Credentials", "true");response.setHeader("Content-Disposition", "inline; filename= " + URLEncoder.encode(pdfFileName, "UTF-8")+".pdf");OutputStream outputStream = null;try {outputStream = response.getOutputStream();outputStream.write(pdfService.generatePdf());outputStream.flush();}  catch (IOException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();} finally {if (outputStream != null) {try {outputStream.flush();outputStream.close();} catch (IOException e) {e.printStackTrace();}}}}}

3、service层

注意项：

1. 指定fsLocalPath存放缓存文件夹
2. AsposeWordPDF中需要指定字体库，windows字体库：C:\Windows\Fonts linux: /usr/share/fonts
(如果没指定字体库，生成pdf会出现中文都是小方格)

public interface PdfService {byte[] generatePdf();}@Service
public class PdfServiceImpl implements  PdfService{@Overridepublic byte[] generatePdf() {//缓存存放String  fsLocalPath="D:\\tmp";ClassPathResource resource = new ClassPathResource("wordTemplate/studentTemplate.docx");String docTemplateFile =  resource.getAbsolutePath();byte[] result = null;File tmpDocOutFile = null;File tmpPdfOutFile = null;try {tmpDocOutFile = File.createTempFile("SxzdPreapprovalReport", ".docx", new File(fsLocalPath));tmpPdfOutFile = File.createTempFile("SxzdPreapprovalReport", ".pdf", new File(fsLocalPath));LoopRowTableRenderPolicy loopRowPolicy = new LoopRowTableRenderPolicy();/*** 注意如果是集合元素一定要放入config*/Configure config = Configure.builder().bind("subjectList", loopRowPolicy).useSpringEL(false).build();List<SubjectResult> subjectList=new ArrayList<SubjectResult>();subjectList.add(new SubjectResult("数学","tom",132));subjectList.add(new SubjectResult("语文","jack",150));Map<String, Object> data = new HashMap<>();data.put("title", "张三基本信息");data.put("subjectList", subjectList);data.put("user", new User("张三","123","高一一班"));XWPFTemplate template = XWPFTemplate.compile(resource.getStream(), config).render(data);template.writeAndClose(new FileOutputStream(tmpDocOutFile));AsposeWordPDF.word2pdf(tmpDocOutFile.getAbsolutePath(), tmpPdfOutFile.getAbsolutePath());result = FileUtils.readFileToByteArray(tmpPdfOutFile);} catch (Exception e) {e.printStackTrace();} finally {FileUtils.deleteQuietly(tmpDocOutFile);FileUtils.deleteQuietly(tmpPdfOutFile);}return result;}
}

4、实体类

@Data
@AllArgsConstructor
public class User {private String userName;private String seqId;private String grade;
}
@Data
@AllArgsConstructor
//@NoArgsConstructor
public class SubjectResult {/*** 课程*/private String  subject;/*** 老师*/private String  teacher;/*** 分数*/private int score;
}

三、测试

1、字体库指定不正确示例

2、正确字体库示例
