Dom4j:Dom SUNdom在加载时,将所有元素全部加载内存DOM4j-第三方。Dom4j是一个开源、灵活的XMLAPI。目前很多开源框架如struts,hibernate都使用dom4j做为解析其xml的工具。支持文档的读写功能和Xpath快速查询操作。这个需要我们自己把它的包导入myeclipse中的。准备DOM4j:包:dom4j.x.jar包结构

1.前言

MS Office2010是可以的,理论上2007版本也可以,博主没试过;

Wps2015是可以的,理论上Wps2016也能用,Wps理论上还兼容MS Office的相关代码,有时间的可以试试;

Wps和Ms Office都需要导入jacob-1.18.jar包,以及将jacob-1.18-x64.dll或者jacob-1.18-x64.dll放置到jdk的bin目录(或者windows的System32/SysWoW64目录下)

而OpenOffice需要导入jodconverter-2.2.1.jar等相关包;

相关包的下载链接,包含实现代码:http://download.csdn.net/detail/huitoukest/9506740

包中的代码可能没有捕获NoClassDefFoundError异常和,建议使用者自行捕获;

2.MS Office2010

核心代码如下:

private static final int wdFormatPDF = 17;
	private static final int xlTypePDF = 0;
	private static final int ppSaveAsPDF = 32;
	//private static final int msoTrue = -1;
	//private static final int msofalse = 0;
	/**
	 * @return 操作成功与否的提示信息. 如果返回 -1, 表示找不到源文件, 或url.properties配置错误; 如果返回 0,
	 *         则表示操作成功; 返回1, 则表示转换失败
	 */
	@Override
