JACOB替换WORD中的字符串

//查找是否存在字符串，若存在则把要查找的字符串设置好。
public static boolean find(Dispatch selection,String text)
{
Dispatch find=Dispatch.call(selection, "Find").toDispatch();
Dispatch.put(find, "Text", text);//设置要查找的文本
Dispatch.put(find,"Forward","True");//向前找
Dispatch.put(find,"Format","True");//设置格式
Dispatch.put(find,"Matchcase","True");//大小写匹配
Dispatch.put(find,"MatchWholeWord","True");//全字匹配
return Dispatch.call(find,"Execute").getBoolean();//查找并选中
}

//全文替换,即文章中所有的字符串都被替换,去掉while则替换一次.
public static void wordFindReplace(String wordpath,String oldtext,String newtext)
{
ActiveXComponent word=new ActiveXComponent("Word.Application");
word.setProperty("Visible",new Variant(false));//设置word不可见
Dispatch docs=word.getProperty("Documents").toDispatch();
Dispatch doc=Dispatch.call(docs, "Open",wordpath).toDispatch();//打开word文件
Dispatch  selection=Dispatch.get(word,"Selection").toDispatch();//选定范围或者插入点

while(find(selection,oldtext))//全文替换
{
Dispatch.put(selection,"Text",newtext);
Dispatch.call(selection, "MoveRight");
}
}
