Download zipped CSV file on client side using Java and struts2

Question

单击按钮后如何下载压缩的CSV文件？

Answer 1

In your Struts Action you need to set the appropriate response headers and then send the file.

  response.setContentType("application/zip");
  response.addHeader("Content-Disposition", 
       "attachment; filename=file.csv.zip");
  IOUtils.copy(zippedCsvFile, response.getOutputStream());

Doing the zip compression on the fly is also an option, as is generating the whole file, of course. If so, you may want to look at DeflaterOutputStream and some library to write CSV data .
