HTML模板生成word，pdf文档

1.获取html模板

java 复制代码

public static void main(String[] args) {
        String htmlContent = getHtmlFileContent(templateName,dataMap);
        String exportType = "pdf";
        if (exportType.equals("pdf")){
            convertToPdf(htmlContent,filePath);
        }else {
            exportWord(htmlContent, filePath);
        }
}

public static String getHtmlFileContent(String templateName, Map<String, Object> contentMap) {
        String htmlText = null;
        try {
            Configuration configuration = new Configuration();
            TemplateLoader templateLoader = new ClassTemplateLoader(PdfUtil.class, "/static/html/");
            configuration.setTemplateLoader(templateLoader);
            Template tpl = configuration.getTemplate(templateName);
            //解析模板并替换动态数据，最终content将替换模板文件中的${content}标签。
            htmlText = FreeMarkerTemplateUtils.processTemplateIntoString(tpl, contentMap);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return htmlText;
}

保存文件为word

 /**
     * 保存文件为word
     */
    public static void exportWord(String content, String filePath) throws Exception {
        byte[] b = content.getBytes("GBK"); //这里是必须要设置编码的，不然导出中文就会乱码。
        ByteArrayInputStream bais = new ByteArrayInputStream(b);//将字节数组包装到流中
        POIFSFileSystem poifs = new POIFSFileSystem();
        DirectoryEntry directory = poifs.getRoot();
        DocumentEntry documentEntry = directory.createDocument("WordDocument", bais); //该步骤不可省略，否则会出现乱码。
        //输出文件
        File file = new File(filePath);
        FileOutputStream ostream = new FileOutputStream(file);
        poifs.writeFilesystem(ostream);
        bais.close();
        ostream.close();
        poifs.close();
    }

保存为pdf文档

java 复制代码

      //String pdfPath = "D:\\cumentPdf.pdf";
      File file = new File(pdfPath);
      try(OutputStream outputStream = new FileOutputStream(file)) {
          // 转换 HTML to PDF
          PdfWriter writer = new PdfWriter(outputStream);
          PdfDocument pdfDocument = new PdfDocument(writer);
          // 设置PDF大小
          pdfDocument.setDefaultPageSize(PageSize.A3);
          // 设置中文
          ConverterProperties converterProperties = new ConverterProperties();
          FontProvider fontProvider = new DefaultFontProvider(true, true, true);
          converterProperties.setFontProvider(fontProvider);
          // html转换PDF
          HtmlConverter.convertToPdf(html, pdfDocument, converterProperties);
          // 关闭
          pdfDocument.close();

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

2. pdf 转 excel

下载jar地址：https://mvnrepository.com/artifact/e-iceblue/spire.pdf/9.7.0

java 复制代码

 <dependency>
	<groupId>e-iceblue</groupId>
	<artifactId>spire.pdf</artifactId>
	<version>9.7.0</version>
	<scope>system</scope>
	<systemPath>${project.basedir}/src/main/resources/lib/spire.pdf-9.7.0.jar</systemPath>
</dependency>

java 复制代码

  import com.spire.pdf.FileFormat;
  import com.spire.pdf.PdfDocument;
  
  public static void pdfToExcel(String pdfPath,String excelPath){
        //创建PdfDocument实例
        PdfDocument pdf = new PdfDocument();
        //加载PDF文档
        pdf.loadFromFile(pdfPath);
        //保存为Excel
        pdf.saveToFile(excelPath, FileFormat.XLSX);
    }

使用excel生成html模板

java 复制代码

<dependency>
	<groupId>e-iceblue</groupId>
	<artifactId>spire.xls.free</artifactId>
	<version>5.1.0</version>
	<scope>system</scope>
    <systemPath>${project.basedir}/src/main/resources/lib/spire.xls.free.5.1.0.jar</systemPath>
</dependency>

package com.suninfo.analyse.test;

import org.springframework.web.bind.annotation.*;
import com.spire.xls.*;

public class ExcelToPdfOrHtml {

    public static void main(String[] args) {
        //读取excel文件地址
        String fileUrl = "D:\\CA_HOME\\upload\\杭州-2023-06-28 16-38-45.xlsx";
        //要转换的sheet页名称
        String sheetName = "Sheet1";

        Workbook wb = new Workbook();
        wb.loadFromFile(fileUrl);
        if(wb==null){
            throw new RuntimeException("文件不存在，请检查文件路径");
        }

        Worksheet worksheet = wb.getWorksheets().get(sheetName);
        PageSetup pageSetup = worksheet.getPageSetup();
        pageSetup.setPaperSize(PaperSizeType.PaperA4);
        pageSetup.setPrintArea("A1:J21");
        pageSetup.setZoom(80);
        if(worksheet==null){
            throw new RuntimeException("工作簿中不存在"+sheetName+"工作表，请检查");
        }

        //pdf存放路径
        String url = "D:\\CA_HOME\\upload\\excelToPdf1.pdf";
        //saveToPdf 如果该路径原本存在，直接生成文件，如果路径不存在，自动创建文件夹生成该路径
//        worksheet.saveToPdf(url);
        worksheet.saveToHtml( "D:\\CA_HOME\\upload\\orgHtmlTemplate.html");
    }
