jacob插件導出文字、表格、圖片到Word

一、介紹

Jacob 是Java-COM Bridge的縮寫，它在Java與微軟的COM組件之間構建一座橋樑。使用Jacob自帶的DLL動態鏈接庫，並通過JNI的方式實現了在Java平臺上對COM程序的調用。

二、安裝和配置

Jacob是一個開源軟件，它的官方站點是：http://danadler.com/jacob/ 大家可以到上面下載源代碼研究，也可以直接下載編譯後的二進制文件。

下載包jacob_x.x.zip，解壓後有幾個文件：jacob.jar、jacob.dll等
把jacob.dll拷貝到%JAVA_HOME%\jre\bin目錄下，%JAVA_HOME%就是JDK的安裝目錄或是C:\Windows\System32下面
接着直接在java IDE中引用jacob.jar就可以使用了

三、jacob.jar的結構

jacob包括兩個部分：

com.jacob.activeX: ActiveXComponent類
com.jacob.com: 其它類和元素

四、Jacob類

Jacob的結構很簡單，包含以下幾個類：

ActiveXComponent Class：封裝了Dispatch對象，用於創建一個封裝了COM組件對象的Java Object
Dispatch Class：用於指向封裝後的MS數據結構。常用的方法有call，subcall，get，invoke…後面會介紹使用方法。
Variant Class：用於映射COM的Variant數據類型。提供Java和COM的數據交換。
ComException Class：異常類

五、Jacob方法

用於訪問COM/DLL對象的方法，讀取、修改COM/DLL對象的屬性。

call method：屬於Dispatch類。用於訪問COM/DLL對象的方法。方法進行了重載，方便不同場合調用。返回一個Variant類型的值。
callSub method：使用方法和call一樣，不過它不返回值。
get method：讀取COM對象的屬性值，返回一個Variant類型值。
put method：設置COM對象的屬性值。
invoke method：call的另一種用法，更復雜一些。
invokesub method：subcall的另一種用法
getProperty method：屬於ActiveXComponent類，讀取屬性值，返回一個Variant類型值。
setProperty method：屬於ActiveXComponent類，設置屬性值。

六、實例

package cn.jcl.test;

import com.jacob.activeX.ActiveXComponent;

import com.jacob.com.ComThread;

import com.jacob.com.Dispatch;

import com.jacob.com.Variant;

public class exportPicToWord {

}

msWordApp.setProperty("Visible", new Variant(visible));

// 與上一句作用相同

// Dispatch.put(msWordApp, "Visible", new Variant(visible));

}

}

Dispatch cells = Dispatch.get(col, "Cells").toDispatch(); // 當前列中單元格

int cellCount = Dispatch.get(cells, "Count").toInt(); // 當前列中單元格數實際上這個數等於row

for (int j = 1; j <= cellCount; j++) { // 每一列中的單元格數

putTxtToCell(newTable, j, i, "第" + j + "行，第" + i + "列");// 與上面四句的作用相同
