如何利用Java-JACOB操作WORD文档

时间:2022-05-12 06:14:48
JACOB是一个JAVA到微软的COM接口的桥梁。使用JACOB允许任何JVM访问COM对象,从而使JAVA应用程序能够调用COM对象。如果你要对 MS Word、Excel 进行处理,JACOB 是一个好的选择。JACOB目前已经成为sourceforge(http://sourceforge.net/projects/jacob-project/)的一个开源项目,本文使用的版本是1.10.1。

因为在项目中用到了这个技术,但是在网上没有查到很符合题目的文章,经过我自己的探索,总结写出了这篇文章。

这篇文章可能不能完全满足你的要求,你也可以按照我的探索方法进行探索:参阅VBA操作Office的组件的书籍,然后参考下面的Tip完成需要的功能。文章最后附完整的测试代码。

生成WORD文档的简单讲解:

1. 初始化com的线程,非常重要,否则第二次创建com对象的时候会出现can’t co-create object异常 (参见jacob的帮助文档),完成操作com组件后要调用 realease方法
ComThread.InitSTA();// 初始化com的线程,非常重要!!使用结束后要调用 realease方法

2. 初始化word应用程序,新建一个空白文档,取得文档内容对象//Instantiate objWord //Declare word object
ActiveXComponent objWord = new ActiveXComponent("Word.Application");

//Assign a local word object
Dispatch wordObject = (Dispatch) objWord.getObject();

//Create a Dispatch Parameter to show the document that is opened
Dispatch.put((Dispatch) wordObject, "Visible", new Variant(true));// new Variant(true)表示word应用程序可见
Tip:设置一个对象的属性的时候,利用Dispatch的put方法,给属性赋值。上面这行语句相当于vb的 wordObject.Visible = true 语句

//Instantiate the Documents Property
Dispatch documents = objWord.getProperty("Documents").toDispatch(); //documents表示word的所有文档窗口,(word是多文档应用程序)

//Add a new word document, Current Active Document
Dispatch document = Dispatch.call(documents, "Add").toDispatch(); // 使用Add命令创建一个新文档,用Open命令可以打开一个现有文档
Tip:调用一个对象的方法的时候,利用Dispatch的call方法,上面的语句相当于vb的document = documents.Add() 语句。

Dispatch wordContent = Dispatch.get(document, "Content").toDispatch(); // 取得word文件的内容
Tip:取得一个对象的成员变量(属性)时利用Dispatch的get方法,上面的语句相当于vb的wordContent = document.Content语句

3. 取得word文档的内容后,可以对其内容进行操作

Dispatch.call(wordContent, "InsertAfter", "这里是一个段落的内容");//插入一个段落

4. 设置刚插入的段落的文字格式
Dispatch paragraphs = Dispatch.get(wordContent, "Paragraphs").toDispatch(); // 所有段落
int paragraphCount = Dispatch.get(paragraphs, "Count").toInt(); // 一共的段落数

// 找到刚输入的段落,设置格式
Dispatch lastParagraph = Dispatch.call(paragraphs, "Item",
new Variant(paragraphCount)).
toDispatch(); // 最后一段
Dispatch lastParagraphRange = Dispatch.get(lastParagraph, "Range").
toDispatch();
Dispatch font = Dispatch.get(lastParagraphRange, "Font").toDispatch();
Dispatch.put(font, "Bold", new Variant(true)); // 设置为黑体
Dispatch.put(font, "Italic", new Variant(true)); // 设置为斜体
Dispatch.put(font, "Name", new Variant("宋体")); //
Dispatch.put(font, "Size", new Variant(12)); //小四
注意:如果想插入一个新的空白行,也需要设置段落的文字格式,否则新插入行的文字格式会于刚插入的段落的格式相同。

5. 将当前文档保存

Dispatch.call(document, "SaveAs", new Variant("C:
abc.doc")); // 保存一个新文档

6. 释放COM线程
ComThread.Release();//释放com线程。根据jacob的帮助文档,com的线程回收不由java的垃圾回收器处理

完整测试代码:(StudyJacob.java 附件中有本文章和java源文件)
import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;
import com.jacob.com.ComThread;

public class StudyJacob {

public static void main(String[] args) {
ComThread.InitSTA();// 初始化com的线程,非常重要!!使用结束后要调用 realease方法

//Instantiate objWord //Declare word object
ActiveXComponent objWord = new ActiveXComponent("Word.Application");

//Assign a local word object
Dispatch wordObject = (Dispatch) objWord.getObject();

//Create a Dispatch Parameter to show the document that is opened
Dispatch.put((Dispatch) wordObject, "Visible", new Variant(true));// new Variant(true)表示word应用程序可见

//Instantiate the Documents Property
Dispatch documents = objWord.getProperty("Documents").toDispatch(); //documents表示word的所有文档窗口,(word是多文档应用程序)

//Add a new word document, Current Active Document
Dispatch document = Dispatch.call(documents, "Add").toDispatch(); // 使用Add命令创建一个新文档,用Open命令可以打开一个现有文档

Dispatch wordContent = Dispatch.get(document, "Content").toDispatch(); // 取得word文件的内容

Dispatch.call(wordContent, "InsertAfter", "这里是一个段落的内容");//插入一个段落

Dispatch paragraphs = Dispatch.get(wordContent, "Paragraphs").toDispatch(); // 所有段落
int paragraphCount = Dispatch.get(paragraphs, "Count").toInt(); // 一共的段落数

// 找到刚输入的段落,设置格式
Dispatch lastParagraph = Dispatch.call(paragraphs, "Item",
new Variant(paragraphCount)).
toDispatch(); // 最后一段
Dispatch lastParagraphRange = Dispatch.get(lastParagraph, "Range").
toDispatch();
Dispatch font = Dispatch.get(lastParagraphRange, "Font").toDispatch();
Dispatch.put(font, "Bold", new Variant(true)); // 设置为黑体
Dispatch.put(font, "Italic", new Variant(true)); // 设置为斜体
Dispatch.put(font, "Name", new Variant("宋体")); //
Dispatch.put(font, "Size", new Variant(12)); //小四

Dispatch.call(document, "SaveAs", new Variant("C:
abc.doc")); // 保存一个新文档
ComThread.Release();//释放com线程。根据jacob的帮助文档,com的线程回收不由java的垃圾回收器处理
}

}

如果你想写一个JAVA代码,其中需要调用JACOB提供的功能,而你还是新手,也许篇文章会大大降低你的花费时间。

我将一个关于JACOB的代码分成下面几个步骤:

1) ActiveXComponent ax = new ActiveXComponent("a1");//构建ActiveX组件实例

其中的a1的值和你需要调用的ActiveX控件有关 MS控件名
a1的值

InternetExplorer
InternetExplorer.Application

Excel
Excel.Application

Word
Word.Application

Powerpoint
Powerpoint.Application

vb/java Script
ScriptControl

windows media Player
WMPlayer.OCX

Outlook
Outlook.Application

Visio
Visio.Application

DAO
DAO.PrivateDBEngine.35

MultiFace
MultiFace.Face

2) Dispatch ds = ax.getObject(). toDispatch();//获取Dispatch对象,我们可以把每个Dispatch对象看成是对Activex控件的一个操作,这一步是获得该ActiveX控件的控制权。
(注: 中提到过Variant类,这里的ax.getObject()便是获得该对象,我们将其转化为任何对象(类型))

3) Dispatch ds1 = Dispatch.get(ds, "a2").toDispatch(); //获取该ActiveX对象数据结构中的a2属性

4) Dispatch d2 = Dispatch.invoke(ds1, "a3", a4, a5, a6).toDispatch(); //功能调用,对ActiveX对象ds1的a3属性执行a4(Dispatch.Put/Dispatch.Get等)操作,执行后a3的值为a5,a6为错误参数码常定义为new int[1],
(注:call、get和put方法都是通过该方法实现的)

5) Dispatch ds2 = Dispatch.put(ds, "a7","a8").toDispatch();//将ActiveX对象ds的属性a4的值设置为a5,该方法返回类型同get一样

6) Dispatch ds3 = Dispatch.call(ds1, "a9", a10);//该方法和get方法非常类似,他是把a9属性赋值给a10

Ok其他的方法我觉得很容易理解,这里就不再做描述了。

下面是一个关于excel的代码,也许对您的进一步自学,会有好处


import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.ComThread;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;

public class ExcelDispatchTest {

public static void main(String[] args) {
ComThread.InitSTA();

ActiveXComponent xl = new ActiveXComponent("Excel.Application");
try {
System.out.println("version=" + xl.getProperty("Version"));
System.out.println("version=" + Dispatch.get(xl, "Version"));
Dispatch.put(xl, "Visible", new Variant(true));
Dispatch workbooks = xl.getProperty("Workbooks").toDispatch();
Dispatch workbook = Dispatch.get(workbooks, "Add").toDispatch();
Dispatch sheet = Dispatch.get(workbook, "ActiveSheet").toDispatch();
Dispatch a1 = Dispatch.invoke(sheet, "Range", Dispatch.Get,
new Object[] { "A1" }, new int[1]).toDispatch();
Dispatch a2 = Dispatch.invoke(sheet, "Range", Dispatch.Get,
new Object[] { "A2" }, new int[1]).toDispatch();
Dispatch.put(a1, "Value", "123.456");
Dispatch.put(a2, "Formula", "=A1*2");
System.out.println("a1 from excel:" + Dispatch.get(a1, "Value"));
System.out.println("a2 from excel:" + Dispatch.get(a2, "Value"));
Variant f = new Variant(false);
Dispatch.call(workbook, "Close", f);
} catch (Exception e) {
e.printStackTrace();
} finally {
xl.invoke("Quit", new Variant[] {});
ComThread.Release();
}
}

        }

    新建一个类T,来测试一下jacob是否能用,代码如下

 package com.test;    

public class T {    

        public staticvoid main(String[] args) {    
                // TODO Auto-generated method stub   
                     MSWordManager ms=new MSWordManager(true);    
//生成一个MSwordManager对象,并且设置显示Word程序   
                     ms.createNewDocument();    
//创建一个新的.doc文件   
                     ms.insertText("Test jacob");    
//插入文本   
                     ms.save("c://1.doc");    
//保存.doc文件   
                     ms.close();    
                     ms.closeDocument();    
        }    

}

运行后C盘生成了1.doc文件,

 

    这样也是没有实际意义,所以我们要加入数据库。
    数据库依然是DB2 9.5 ,用户名db2admin 密码abc 表名admin
    我在这个项目中添加了Hibernate框架,Java程序代码如下

 package com.dao;    

import java.util.List;    

public class Test {    
        public staticvoid main(String[] args) {    
                AdminDAO dao = new AdminDAO();    
                List list = dao.findAll();    
                MSWordManager ms=new MSWordManager(false);    
                ms.createNewDocument();    
                for (int i=1;i<=list.size();i++){    
                        Admin admin = (Admin)list.get(1);    
                        ms.insertText(admin.getName());    
                        ms.insertText("本文章由jacob自动生成");    
                        ms.moveEnd();    
                }    
                 ms.save("c://1.doc");    
                 ms.closeDocument();    
                 ms.close();                
        }    
}

    运行程序后,进入c盘,打开生成的1.doc文件。

 

    这就是Java利用开源工具jacob操作Microsoft Word

上一次我们用iText这个工具在Java环境下操作PDF文件,现在我们换一个工具:BFO
iText的确小巧,但是功能也有限制,只能简单的生成PDF文件,BFO却不同,能设置字体、版面等元素。
如何利用Java-JACOB操作WORD文档
官方网站为:http://big.faceless.org/products/pdf/
最新版本是:2.11.4
官方的解释:The Big Faceless Java PDF Library is the smartest Java PDF library for creating, editing, displaying and printing Acrobat PDF documents.
下载链接为:http://big.faceless.org/products/bfopdf-2.11.4.zip
 
我的开发环境:JDK1.6+MyEclipse7+Tomcat5.5.27
首先在MyEclipse中新建一个项目BFO,将下载的jar文件放入该项目的类库中。
