第一步 需要下载jar包和jacob-1.14.3-x64.dll * <dependency> * <groupId>net.sf.jacob-project</groupId> * <artifactId>jacob</artifactId> * <version>1.14.3</version> * </dependency> *第二步 把jacob-1.14.3-x64.dll 放到java/bin目录下 电脑环境 win10 office2016支持文件类型 doc，docx，xls，xlsx,ppt,pptx
下面是源代码package com.example.demo.xs;import com.jacob.activeX.ActiveXComponent;import com.jacob.com.Dispatch;import com.jacob.com.Variant;import java.io.File;import java.util.logging.Level;import java.util.logging.Logger;/** * 需要jar包和jacob-1.14.3-x64.dll * <dependency> * <groupId>net.sf.jacob-project</groupId> * <artifactId>jacob</artifactId> * <version>1.14.3</version> * </dependency> * * 把jacob-1.14.3-x64.dll 放到java/bin目录下 * * 电脑环境 win10 office2016 * @author 苑庆涛 * @create 2019-07-22 16:22 */public class Test { private static Logger logger = Logger.getLogger(WordApp.class.getName()); public static void main(String[] args) { } /** * 示例 toPdf("d:\\testold\\e3.xls","d:\\testnew\\e3.pdf","xlsx") * @param src 文件路径 * @param tar pdf文件路径 * @param type 文件类型 */ public static void toPdf(String src,String tar,String type){ if(type.startsWith("doc")){ wordToPdf(src,tar); }else if(type.startsWith("xls")){ excelToPdf(src,tar); }else if(type.startsWith("ppt")){ pptToPdf(src,tar); } } public static void wordToPdf(String src, String tar) { ActiveXComponent app = null; Dispatch doc = null; try { app = new ActiveXComponent("Word.Application"); app.setProperty("Visible", new Variant(false)); app.setProperty("AutomationSecurity", new Variant(3)); Dispatch docs = app.getProperty("Documents").toDispatch(); doc = Dispatch.call(docs, "Open", src, false, true) .toDispatch(); File target = new File(tar); if (target.exists()) { target.delete(); } Dispatch.call(doc, "SaveAs", tar,17); } catch (Throwable t) { logger.log(Level.SEVERE, t.getMessage(), t); } finally { if (doc != null) { try { Dispatch.call(doc, "Close", false); } catch (Throwable t) { logger.log(Level.SEVERE, t.getMessage(), t); } } if (app != null) { try { app.invoke("Quit",0); app.safeRelease(); } catch (Throwable t) { logger.log(Level.SEVERE, t.getMessage(), t); } } } } public static void excelToPdf(String src, String tar) { ActiveXComponent app = null; Dispatch doc = null; try { app = new ActiveXComponent("Excel.Application"); app.setProperty("Visible", new Variant(false)); app.setProperty("AutomationSecurity", new Variant(3)); Dispatch docs = app.getProperty("Workbooks").toDispatch(); doc = Dispatch.call(docs, "Open", src, false, true) .toDispatch(); File target = new File(tar); if (target.exists()) { target.delete(); } Dispatch.call(doc, "ExportAsFixedFormat", 0, tar ); } finally { if (doc != null) { try { Dispatch.call(doc, "Close", false); } catch (Throwable t) { logger.log(Level.SEVERE, t.getMessage(), t); } } if (app != null) { try { app.invoke("Quit"); app.safeRelease(); } catch (Throwable t) { logger.log(Level.SEVERE, t.getMessage(), t); } } } } public static void pptToPdf(String src, String tar) { ActiveXComponent app = null; Dispatch doc = null; try { app = new ActiveXComponent("PowerPoint.Application"); app.setProperty("AutomationSecurity", new Variant(3)); Dispatch docs = app.getProperty("Presentations").toDispatch(); doc = Dispatch.call( docs, "Open", src, true, true,false).toDispatch(); File target = new File(tar); if (target.exists()) { target.delete(); } Dispatch.call(doc, "SaveAs",tar,32); } finally { if (doc != null) { try { Dispatch.call(doc, "Close"); } catch (Throwable t) { logger.log(Level.SEVERE, t.getMessage(), t); } } if (app != null) { try { app.invoke("Quit"); app.safeRelease(); } catch (Throwable t) { logger.log(Level.SEVERE, t.getMessage(), t); } } } }}
