实现要求:浏览器页面点击,文件下载
前台实现
function down(data){
var content = data.modelContent;
window.location.href = getRootPath_web() +"auditData/download?content="+content;
}
后台实现:
@RequestMapping("/download")
public void download(String content, HttpServletResponse response) {
try {
// 要下载的文件的路径。
File file = new File(content);
// 取得文件名。
String filename = file.getName();
// 以流的形式下载文件。
InputStream fis = new BufferedInputStream(new FileInputStream(content));
byte[] buffer = new byte[fis.available()];
fis.read(buffer);
fis.close();
// 清空response
response.reset();
// 设置response的Header
response.addHeader("Content-Disposition", "attachment;filename=" + new String(filename.getBytes()));
response.addHeader("Content-Length", "" + file.length());
OutputStream toClient = new BufferedOutputStream(response.getOutputStream());
response.setContentType("application/octet-stream");
response.setCharacterEncoding("utf-8");
toClient.write(buffer);
toClient.flush();
toClient.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
