本文章向大家介紹如何在Java中使用jacob將word轉換成pdf,主要包括如何在Java中使用jacob將word轉換成pdf的使用實例、應用技巧、基本知識點總結和需要注意事項,具有一定的參考價值,需要的朋友可以參考一下。
Java主要應用于:1. web開發;2. Android開發;3. 客戶端開發;4. 網頁開發;5. 企業級應用開發;6. Java大數據開發;7.游戲開發等。
需要自定的maven依賴,如下:
<dependency> <groupId>com.jacob</groupId> <artifactId>jacob</artifactId> <version>1.7</version> <scope>system</scope> <systemPath>${basedir}/../fileConvertApp/src/main/webapp/WEB-INF/lib/jacob.jar</systemPath> </dependency>
然后需要注意的是jar的地址,需要根據自己的情況修改
接下來我們貼一下具體使用的代碼片段
import java.io.File; import org.apache.log4j.Logger; import com.jacob.activeX.ActiveXComponent; import com.jacob.com.Dispatch; import com.jacob.com.Variant; /** * Converter Util * * @author Jason * */ public class OfficeConverterUtil { /** * log */ private static Logger logger = Logger.getLogger(OfficeConverterUtil.class);

} } }
根據自己的調試,試驗一下吧。
另外還有一段WPS轉PDF,也貼一下,供大家參考一下
public void wps2PDF(String inputFile,String pdfFile) { File sFile = new File(inputFile); File tFile = new File(pdfFile); ActiveXComponent wps = null; try { ComThread.InitSTA(); wps = new ActiveXComponent("wps.application"); ActiveXComponent doc = wps.invokeGetComponent("Documents").invokeGetComponent("Open", new Variant(sFile.getAbsolutePath())); doc.invoke("ExportPdf", new Variant(tFile.getAbsolutePath())); doc.invoke("Close"); doc.safeRelease(); } catch (Exception e) { System.out.println(e.getMessage()); } finally { if (wps != null) { wps.invoke("Terminate"); wps.safeRelease(); } ComThread.Release(); } }
