## java使用jacob控制office组件实现word、excel、PPT转换成PDF ##

本文介绍java直接调用Microsoft Office 或 WPS组件实现word、excel、PPT转换成PDF。此方法只适用windows服务器

1.  首先要下载jacob-1.14.3-x64.dll或jacob-1.14.3-x86.dll组件，将组件放到jdk\\bin目录下  
    [下载地址][Link 1]  
    [网盘下载][Link 2] 提取码：mz4i
2.  配置jacob-1.14.3maven

<dependency>
       	    <groupId>net.sf.jacob-project</groupId>
       	    <artifactId>jacob</artifactId>
       	    <version>1.14.3</version>
       	</dependency>

1.  实现代码

import com.jacob.activeX.ActiveXComponent;
    import com.jacob.com.Dispatch;
    import com.jacob.com.Variant;
    
    /** 1. office转换工具 */
    public class OfficeConverterUtils { 
      private static final int WDFO_RMATPDF = 17;
      private static final int XLTYPE_PDF = 0;
      private static final int PPT_SAVEAS_PDF = 32;
      public static final int WORD_HTML = 8;
      public static final int WORD_TXT = 7;
      public static final int EXCEL_HTML = 44;
    
      private OfficeConverterUtils() { 
          throw new AssertionError();
      }
    
      /** * office转换成PDF * @param officePath office相关文件 * @param postfix 文件后缀 * @param pdfPath PDF文件路径 * @return 成功失败 */
      public static boolean officeToPdf(String officePath, String postfix, String pdfPath) { 
          if (postfix.startsWith("ppt")) { 
              return pptToPdf(officePath, pdfPath);
          } else if (postfix.startsWith(".xls")) { 
              return excelToPdf(officePath, pdfPath);
          } else { 
              return wordToPdf(officePath, pdfPath);
          }
      }
    
      /** * word转换成PDF * @param wordPath 文件路径 * @param pdfPath 文件路径 * @return 成功失败 */
      public static boolean wordToPdf(String wordPath, String pdfPath) { 
          ActiveXComponent msWordApp = new ActiveXComponent("Word.Application");
          msWordApp.setProperty("Visible", new Variant(false));
          Dispatch docs = Dispatch.get(msWordApp, "Documents").toDispatch();
          Dispatch doc = Dispatch.invoke(docs, "Open", Dispatch.Method, new Object[]{ wordPath, new Variant(false), new Variant(true)}, new int[1]).toDispatch();
    
          Dispatch.invoke(doc, "SaveAs", Dispatch.Method, new Object[]{ pdfPath, new Variant(WDFO_RMATPDF)}, new int[1]);
          if (null != doc) { 
              Dispatch.call(doc, "Close", false);
          }
          return true;
      }
    
      /** * excel转换成PDF * @param inputPath 文件路径 * @param pdfPath 文件路径 * @return 成功失败 */
      public static boolean excelToPdf(String inputPath, String pdfPath) { 
          ActiveXComponent activeXComponent = new ActiveXComponent("Excel.Application");
          activeXComponent.setProperty("Visible", false);
    
          Dispatch excels = activeXComponent.getProperty("Workbooks").toDispatch();
          Dispatch excel = Dispatch.call(excels, "Open", inputPath, false, true).toDispatch();
          Dispatch.call(excel, "ExportAsFixedFormat", XLTYPE_PDF, pdfPath);
          Dispatch.call(excel, "Close", false);
          activeXComponent.invoke("Quit");
          return true;
      }
    
      /** * ppt转换成PDF * @param inputPath 文件路径 * @param pdfPath 文件路径 * @return 成功失败 */
      public static boolean pptToPdf(String inputPath, String pdfPath) { 
          // ComThread.InitSTA();
          ActiveXComponent activeXComponent = new ActiveXComponent("PowerPoint.Application");
          // activeXComponent.setProperty("Visible", new Variant(false));
          Dispatch ppts = activeXComponent.getProperty("Presentations").toDispatch();
    
          Dispatch ppt = Dispatch.call(ppts, "Open", inputPath, false, // ReadOnly
                  true, // Untitled指定文件是否有标题
                  true// WithWindow指定文件是否可见
                                      ).toDispatch();
          Dispatch.callN(ppt, "SaveAs", new Variant(pdfPath));
          Dispatch.call(ppt, "Close");
          activeXComponent.invoke("Quit");
          return true;
      }
    }

**FQA**

1.如果office转换成PDF报 com.jacob.com.ComFailException: Can’t get object clsid from progid错误。原因有可能是tomcat配置使用windows服务启动导致，具体原因还没有弄清除。处理方法tomcat将windows服务启动关闭，使用tomcat的脚本启动解决问题。
