springboot java8使用jacob，aspose两种方式实现excel、word转pdf

其实还有一种spire转化PDF，不过这种是收费的还有限制只能导出3个sheet页数据也有限制

1.使用jacob

1.1引入依赖

        <!--jacob依赖--><dependency><groupId>com.jacob</groupId><artifactId>jacob</artifactId><version>1.19</version><scope>system</scope><!--本地的jacob.jar的路径--><systemPath>D:/kaifa/jacob-1.20/jacob-1.20/jacob.jar</systemPath></dependency>

1.2 工具类

package com.qiang;import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.ComThread;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;/*** @ClassName: OfficeToPDF  * @author yinzl* @date 2020-05-23* 调用Microsoft excel，必须安装Microsoft Offcie 2007以上版本* 需要引入jar包：jacob.jar,解压jacob_1.19.zip ，将文件jacob-1.19-x64.dll  放到jdk安装目录bin文件夹下， jdk要求1.8* 如果出现不能设置类 PageSetup 的 PaperSize 属性的问题，是因为打印机设置中没有任何打印机的原因，使得页面设置失败，在添加任意打印机后，程序运行正常* */
public class OfficeToPDF {private static final Integer WORD_TO_PDF_OPERAND = 17;private static final Integer PPT_TO_PDF_OPERAND = 32;private static final Integer EXCEL_TO_PDF_OPERAND = 0;public static void doc2pdf(String srcFilePath, String pdfFilePath) throws Exception {  ActiveXComponent app = null;  Dispatch doc = null;  try {  ComThread.InitSTA();  app = new ActiveXComponent("Word.Application");  app.setProperty("Visible", false);  Dispatch docs = app.getProperty("Documents").toDispatch(); Object[] obj = new Object[]{srcFilePath, new Variant(false),  new Variant(false),//是否只读  new Variant(false),   new Variant("pwd")};doc = Dispatch.invoke(docs, "Open", Dispatch.Method, obj, new int[1]).toDispatch();
//          Dispatch.put(doc, "Compatibility", false);  //兼容性检查,为特定值false不正确  Dispatch.put(doc, "RemovePersonalInformation", false);  Dispatch.call(doc, "ExportAsFixedFormat", pdfFilePath, WORD_TO_PDF_OPERAND); // word保存为pdf格式宏，值为17  }catch (Exception e) {  e.printStackTrace();throw e;} finally {  if (doc != null) {  Dispatch.call(doc, "Close", false);  }  if (app != null) {  app.invoke("Quit", 0);  }  ComThread.Release();  }  }  public static void ppt2pdf(String srcFilePath, String pdfFilePath) throws Exception {ActiveXComponent app = null;Dispatch ppt = null;try {ComThread.InitSTA();app = new ActiveXComponent("PowerPoint.Application");Dispatch ppts = app.getProperty("Presentations").toDispatch();/** call * param 4: ReadOnly* param 5: Untitled指定文件是否有标题* param 6: WithWindow指定文件是否可见* */ppt = Dispatch.call(ppts, "Open", srcFilePath, true,true, false).toDispatch();Dispatch.call(ppt, "SaveAs", pdfFilePath, PPT_TO_PDF_OPERAND); // ppSaveAsPDF为特定值32} catch (Exception e) {e.printStackTrace();throw e;} finally {if (ppt != null) {Dispatch.call(ppt, "Close");}if (app != null) {app.invoke("Quit");}ComThread.Release();}}public static boolean excel2Pdf(String inFilePath, String outFilePath) throws Exception {ActiveXComponent ax = null;Dispatch excel = null;try {ComThread.InitSTA();ax = new ActiveXComponent("Excel.Application");ax.setProperty("Visible", new Variant(false));ax.setProperty("AutomationSecurity", new Variant(3)); // 禁用宏Dispatch excels = ax.getProperty("Workbooks").toDispatch();Object[] obj = new Object[]{ inFilePath, new Variant(false),new Variant(false) };excel = Dispatch.invoke(excels, "Open", Dispatch.Method, obj, new int[9]).toDispatch();//将excel表格 设置成A3的大小Dispatch sheets = Dispatch.call(excel, "Worksheets").toDispatch();  Dispatch sheet = Dispatch.call(sheets, "Item", new Integer(1)).toDispatch();  Dispatch pageSetup = Dispatch.call(sheet, "PageSetup").toDispatch();//Dispatch.put(pageSetup, "PaperSize", new Integer(8));//A3是8，A4是9，A5是11等等  //该行代码报错：不能设置类 PageSetup 的 PaperSize 属性，暂时关闭// 转换格式Object[] obj2 = new Object[]{ new Variant(EXCEL_TO_PDF_OPERAND), // PDF格式=0outFilePath, new Variant(0)  //0=标准 (生成的PDF图片不会变模糊) ; 1=最小文件};Dispatch.invoke(excel, "ExportAsFixedFormat", Dispatch.Method,obj2, new int[1]);} catch (Exception es) {es.printStackTrace();return false;// throw es;} finally {if (excel != null) {Dispatch.call(excel, "Close", new Variant(false));}if (ax != null) {ax.invoke("Quit", new Variant[] {});ax = null;}ComThread.Release();}return true;}public static void main(String[] args){String inFilePath = "D:\\temp\\456dda29f26f45e2878c99b5af5d489b.xlsx";String outFilePath = "D:\\temp\\test.pdf";try {OfficeToPDF.excel2Pdf(inFilePath,outFilePath);} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}
}

1.3 测试拿出提前准备好的excel文件

1.4运行

    @Testpublic void test5() throws Exception {long old = System.currentTimeMillis();String inFilePath="C:\\Users\\ex_lizhq5\\Downloads\\用户-导出.xlsx";OfficeToPDF.excel2Pdf(inFilePath,"C:\\Users\\ex_lizhq5\\Downloads\\用户-导出.pdf");long now = System.currentTimeMillis();//共耗时：33.234秒 33.4System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒");  //转化用时}

1.6结果

2.使用aspose

2.1引入依赖

        <dependency><groupId>com.aspose</groupId><artifactId>aspose-words</artifactId><version>20.7</version><classifier>jdk17</classifier></dependency><dependency><groupId>com.aspose</groupId><artifactId>aspose-slides</artifactId><version>20.7</version><classifier>jdk16</classifier></dependency><dependency><groupId>com.aspose</groupId><artifactId>aspose-cells</artifactId><version>20.7</version></dependency><repositories><repository><id>AsposeJavaAPI</id><name>Aspose Java API</name><url>https://repository.aspose.com/repo/</url></repository></repositories>

2.3 准备生成好的excel文件，还是上面那个

2.4 测试

    @Testpublic void test3() throws IOException {String inFilePath="C:\\Users\\ex_lizhq5\\Downloads\\用户-导出 (2).xlsx";//String outFilePath="D://wcmis_file/email/井控安全风险分级管控台账(2022年5月).pdf";//OfficeToPDF.excel2Pdf(inFilePath,outFilePath);//aspose  56s 56.869PdfUtil.exceOfPdf(inFilePath);
