Java实现浏览器下载文件及文件预览

Java实现浏览器下载⽂件及⽂件预览插曲想记录⼀下，以后可以来粘贴复制⽤。

⼀、浏览器下载⽂件

setContentType() 该实体头的作⽤是让服务器告诉浏览器它发送的数据属于什么⽂件类型。

没有缓存

response.addHeader("Pargam", "no-cache");

response.addHeader("Cache-Control", "no-cache");

public static void setResponseHeader(HttpServletResponse response, String name) {

try {

name = new Bytes(), "ISO8859-1");

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

}

response.setContentType("application/docx");

//要保存的⽂件名

response.setHeader("Content-Disposition", "attachment;filename=" + name + ".docx");

response.addHeader("Pargam", "no-cache");

response.addHeader("Cache-Control", "no-cache");

}

⼆、浏览器预览⽂件只需要把下⾯这⾏注释就好

response.setHeader("Content-Disposition", "attachment;filename=" + name + ".docx");

setContentType() 中的参数选择：

⽂件扩展名Content-Type(Mime-Type)⽂件扩展

名

Content-Type(Mime-Type)

.*（⼆进制流，不知道下载⽂件类

型）
