jsp word文档处理

Question

jsp构造出work文档之后，怎样通过一个Action把work文档保存，并且我不显示work文档

Answer 1

你既然都可以通过“jsp生成的word文档”那么你读取word里面的数据应该没什么难度了啊，你保存是下载到本地吗？你想要操作word的话给你推荐个jacob（开源的第三方工具包），你要是需要下载的话，我下面给你贴出来一个通过serlvet下载文件的类，配置在tomcat的web.xml后直接调用可以下载：

        //取得文件保存的路径
        IReaderPath readerPath = new ReadSavePathImpl();

        InputStream is = null;
        OutputStream os = null;
        try{

            int len = 0;
            while((len=is.read(buf,0,buf.length))>0){

            }

            try {

}
private void p(Object obj){
    System.out.println("[ FileDowndoadAction   ]"+obj);
