java使用jacob将word，excel，ppt转成html

用到的jar包及插件：

        jacob-1.18（ jacob.jar）

       jacob-1.18（ jacob-1.18-x64.dll）（32位）

       jacob-1.18（ jacob-1.18-x86.dll）（64位）

1.dll文件根据电脑系统版本和jdk版本（32或者64位）来选择。

2.使用main方法时将dll文件放到C盘Windows\System32目录下，项目调用此方法时将dll文件放到jdk的jre\bin目录下。

3.需要注意一点如果运行还是报错的话，把x64.dll（32位）放到Windows\System32目录下，把x86.dll（32位）放到

Windows\SysWOW64目录下。这样肯定可行。

4.然后把jar包导入到项目工程中，注意对应版本号。

注：此方法来源与网上，然后我给整合了一下。网上的ppt转html我怎么试都不成功，转换失败全是乱码，后来我只能

把ppt转成PDF，然后再将PDF转成html。虽然麻烦但是也能实现最终的目的，谁有成功的方法欢迎分享，谢谢。

下面直接贴java代码：

public class OfficeToXML {

         private final static OfficeToXML oOfficeToXML = new OfficeToXML();  
	
	public static OfficeToXML getInstance() {  
        return oOfficeToXML;  
    } 
	
	public OfficeToXML() {  
    }
