Spring Integration Guide

This chapter introduces how to integrate and use Fesod in the Spring framework to generate spreadsheet files.

Spring Controller Example

Overview

In Spring Boot projects, you can generate spreadsheet files and provide download functionality through HTTP interfaces, making it convenient to use Fesod in web environments.

Code Example

@GetMapping("download")
public void download(HttpServletResponse response) throws IOException {
    response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
    response.setCharacterEncoding("utf-8");
    String fileName = URLEncoder.encode("demo", "UTF-8").replaceAll("\\+", "%20");
    response.setHeader("Content-disposition", "attachment;filename*=utf-8''" + fileName + ".xlsx");

    FesodSheet.write(response.getOutputStream(), DemoData.class)
            .sheet("Sheet1")
            .doWrite(data());
}
