文章介绍了将多个文档写入同一个Word文件并实现下载的相关内容，聚焦于信息技术中文件处理与操作方面。
本文章作用于将多个文档写入同一个word,将其下载
public void importWord(HttpServletRequest request,HttpServletResponse response) throws IOException {

// 1.读取要下载的内容

// 2. 告诉浏览器下载的方式以及一些设置
// 解决文件名乱码问题，获取浏览器类型，转换对应文件名编码格式，IE要求文件名必须是utf-8, firefox要求是iso-8859-1编码
String agent = request.getHeader("user-agent");
if (agent.contains("FireFox")) {

// 设置下载文件的mineType，告诉浏览器下载文件类型
String mineType = request.getServletContext().getMimeType(filename);

// 设置一个响应头，无论是否被浏览器解析，都下载
