spring MVC 下载文件

springle MVC中如何下载文件呢?

比struts2 下载文件简单得多

先看例子:

@ResponseBody
	@RequestMapping(value = "/download",produces="application/octet-stream")
	public byte[] downloadFile(HttpServletRequest request, HttpServletResponse response,String contentType2)
			throws IOException {
		byte[]bytes=FileUtils.getBytes4File("D:\\Temp\\cc.jpg");
		response.addHeader("Content-Disposition", "inline;filename=\"a.jpg\"");
		return bytes;

	}

 在浏览器中访问:http://localhost:8080/tv_mobile/video/download

 

注意:

(1)使用注解@ResponseBody 表示action返回的内容直接作为应答体返回;

(2)通过produces 设置返回的content type;

(3)直接返回要下载的文件的二进制数组
