JAVA+PageOffice最简单的在线只读打开Word文档

用Java读取Word文档由于Word的编码方式比较复杂，所以Word文档不可能通过流的方式直接读取；当然如果Word可以转化成TXT文件就可以直接读取了；目前读取Word比较好的开源工具是Poi及Jacob，感觉Poi读取功能要比Jacob略逊一筹，毕竟Jacob可以直接调用Word的COM组件；但是微软产品不开放源码，所以Jacob读取Word文档也只能是摸着石头过河，一点一点破解了。

Jacob读取Word内容，由于Word内容的复杂性，读取也是非常不方便的，目前可以有＂按段落读取＂，＂按书签读取＂及＂按照表格读取＂等几种形式。

示例讲解（通过Java FileReader,Jacob两种方式读取Word内容)一．通过java流读取Word内容复制代码1.import java.io.BufferedReader;2.import java.io.FileReader;3.import java.io.IOException;4.5.public class ReadWordByStream {6.public static void main(String[] args) throws IOException {7. String rowContent = new String();8. String content = new String();9. BufferedReader in = new BufferedReader(new FileReader("d:\\test3.doc"));10. while ((rowContent = in.readLine()) != null) {11.content = content + rowContent + "\n";12. }13. System.out.println(content.getBytes());14. System.out.println(new String(content.getBytes(),"utf-8"));//因为编码方式不同，不容易解析15. in.close();16.}17.18.}二．通过Jacob读取Word内容复制代码1.import com.jacob.activeX.ActiveXComponent;2.import Thread;3.import .Dispatch;4.import .Variant;5.6.public class WordReader {7.public static void main(String args[]) {8. ComThread.InitSTA();// 初始化com的线程9. ActiveXComponent wordApp = new ActiveXComponent("Word.Application"); // 启动word10. // Set the visible property as required.11. Dispatch.put(wordApp, "Visible", new Variant(true));// //设置word可见12. Dispatch docs = wordApp.getProperty("Documents").toDispatch();//所有文档窗口13.// String inFile = "d:\\test.doc";14.// Dispatch doc = Dispatch.invoke(docs,"Open",Dispatch.Method,15.// new Object[] { inFile, new Variant(false),new Variant(false) },//参数３,false:可写，true:只读16.// new int[1]).toDispatch();//打开文档17.18. Dispatch doc = Dispatch.call(docs, "Add").toDispatch(); //创建一个新文档19. Dispatch wordContent = Dispatch.get(doc, "Content").toDispatch(); //取得word文件的内容20.

Dispatch.call(wordContent, "InsertAfter", "current paragraph"+j+"\r");31.}32. Dispatch paragraphs = Dispatch.get(wordContent, "Paragraphs")33. .toDispatch(); //所有段落34. int paragraphCount = Dispatch.get(paragraphs, "Count").getInt();35. System.out.println("paragraphCount:"+paragraphCount);36.37. for (int i = 1; i <= paragraphCount; i++) {38.Dispatch paragraph = Dispatch.call(paragraphs, "Item",39.new Variant(i)).toDispatch();40.Dispatch paragraphRange = Dispatch.get(paragraph, "Range")41..toDispatch();42.String paragraphContent = Dispatch.get(paragraphRange, "Text")43..toString();44.System.out.println(paragraphContent);45.//Dispatch.call(selection, "MoveDown");46. }47. // WordReader.class.getClass().getResource("/").getPath().substring+"test.doc";48. Dispatch.call(doc, "SaveAs","d:\\wordreader.doc");49. // Close the document without saving changes50. // 0 = wdDoNotSaveChanges51. // -1 = wdSaveChanges52. // -2 = wdPromptToSaveChanges53.

JAVA+PageOffice最简单的在线只读打开Word文档在本地磁盘上打开一个Word文件很容易，但想在网页中打开一个Word文件就没有那么容易了。

但若通过PageOffice开发平台，则要实现这一功能则很容易，下面就以只读形式在线打开一个Word文档为例介绍一下实现过程。

具体实现步骤如下：第一步：拷贝文件到WEB项目的“WEB-INF/lib”目录下。

拷贝PageOffice 示例中下的“WEB-INF/lib”路径中的pageoffice.cab和pageoffice.jar到新建项目的“WEB-INF/lib”目录下。

第二步：修改WEB项目的配置文件。

将如下代码添加到配置文件中：<!-- PageOffice Begin --><servlet><servlet-name>poserver</servlet-name><servlet-class>com.zhuozhengsoft .pageoffice.poserver.Server</servlet-class></servlet><servlet-mapping><servlet-name>poserver</servlet-name><url-pattern>/poserver.do</url-pattern></servlet-mapping><servlet-mapping><servlet-name>poserver</servlet-name><url-pattern>/pageoffice.cab</url-pattern></servlet-mapping><servlet-mapping><servlet-name>poserver</servlet-name><url-pattern>/popdf.cab</url-pattern></servlet-mapping><servlet-mapping><servlet-name>poserver</servlet-name><url-pattern>/sealsetup.exe</url-pattern></servlet-mapping><servlet><servlet-name>adminseal</servlet-name><servlet-class>com.zhuozhengsoft.pageoffice.poserver.AdminSeal </servlet-class></servlet><servlet-mapping><servlet-name>adminseal</servlet-name><url-pattern>/adminseal.do</url-pattern></servlet-mapping><servlet-mapping><servlet-name>adminseal</servlet-name><url-pattern>/loginseal.do</url-pattern></servlet-mapping><servlet-mapping><servlet-name>adminseal</servlet-name><url-pattern>/sealimage.do</url-pattern></servlet-mapping><mime-mapping><extension>mht</extension><mime-type>message/rfc822</mime-type></mime-mapping><context-param><param-name>adminseal-password</param-name><param-value>123456</param-value></context-param><!-- PageOffice End -->第三步：添加引用。

Java实现办公⽂档在线预览功能java实现办公⽂件在线预览功能是⼀个⼤家在⼯作中也许会遇到的需求，⽹上些公司专门提供这样的服务，不过需要收费如果想要免费的，可以⽤openoffice，实现原理就是：通过第三⽅⼯具openoffice，将word、excel、ppt、txt等⽂件转换为pdf⽂件流；当然如果装了Adobe Reader XI，那把pdf直接拖到浏览器页⾯就可以直接打开预览，前提就是浏览器⽀持pdf⽂件浏览。
