最近项目中需要在页面中预览word文件，虽说word本身就可以在页面中打开，但是有两个弊端，1是可客户端必须安装word， 2是客户端的环境以及office版本有差异，会造成预览不稳定。在网上找了一下，发现poi可以把word装换成txt,但是格式都丢了,只有光秃秃的文本,又搜jacob, 网友们众说纷纭, 最后还是自己sourceforge上下载jacob并阅读doc搞定了.
1 goto http://sourceforge.net/projects/jacob-project/ and download latest library of jacob.
下载的zip文件结构如下:
2 intel cpu的机器拷贝jacob-1.15-M3-x86.dll到%JAVA_HOME%/jre/bin, AMD cpu的机器拷贝jacob-1.15-M3-x64.dll. 不过请确保jre目录是你正在使用的jre, 因为现在很多eclipse版本自己带jre. 这个在eclipse windows-> preferences -> installed jres可以查看.
3 拷贝jacob.jar到你项目目录的lib下面并确保加入到了classpath.
准备工作完毕, 现在就写程序了.
import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;
public class Test {
public static void main(String[] args) {
ActiveXComponent app = new ActiveXComponent("Word.Application");
app.setProperty("Visible", new Variant(false));
Dispatch doc1 = app.getProperty("Documents").toDispatch();
//打开aaaa.doc
Dispatch doc2 = Dispatch.invoke(
doc1,
"Open",
Dispatch.Method,
new Object[]{"e:\\aaaa.doc", new Variant(false), new Variant(true)},
new int[1]
).toDispatch();
//另存为aaaa.html
Dispatch.invoke(
doc2,
"SaveAs",
Dispatch.Method,
new Object[]{
"c:\\aaaa.html",
new Variant(8)//7为txt格式， 8保存为html格式
},
new int[1]
);
Variant f = new Variant(false);
Dispatch.call(doc2, "Close", f);
}
}
使用起来很简单.
当然jacob不光可以做word to html, 还可以做很多事情:
Jacob is a Java library that lets Java applications communicate with Microsoft Windows DLLs or COM libraries. It does this through the use of a custom DLL that the Jacob Java classes communicate with via JNI. The library and dll isolate the Java developer from the underlying windows libraries so that
