如何导出java工程项目里面的excel文件

Posted 2023-02-24

web项目，比如在java工程下有一个table的文件夹里面有demo1.xls文件，我想要通过在web页面上点击下载按钮，实现下载demo1.xls文件到计算机本地
求大神帮忙

request.setCharacterEncoding("utf-8");
String title = request.getParameter("title");
//title = URLDecoder.decode(title,"utf-8");
int maid = Integer.parseInt(request.getParameter("maid"));
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition" ,"attachment;filename="+new String((title+".xls").getBytes(),"ISO-8859-1"));
//ManuscriptAction down=new ManuscriptAction();

WebApplicationContext webAppContext = WebApplicationContextUtils.getRequiredWebApplicationContext(getServletContext());//得到WebApplicationContext 。
ManuscriptDaoImp cocAutoService = (ManuscriptDaoImp) webAppContext.getBean("manuscriptDaoImp");
cocAutoService.exportMan(maid,title,response.getOutputStream());

out.clear();
out = pageContext.pushBody();

我的下载代码 提供你参考 参考技术A request.setCharacterEncoding("utf-8");
   String title = request.getParameter("title");
//title = URLDecoder.decode(title,"utf-8");
int maid = Integer.parseInt(request.getParameter("maid"));
   response.setContentType("application/vnd.ms-excel");
   response.setHeader("Content-Disposition" ,"attachment;filename="+new String((title+".xls").getBytes(),"ISO-8859-1"));
//ManuscriptAction down=new ManuscriptAction();

WebApplicationContext webAppContext = WebApplicationContextUtils.getRequiredWebApplicationContext(getServletContext());//得到WebApplicationContext 。
ManuscriptDaoImp cocAutoService = (ManuscriptDaoImp) webAppContext.getBean("manuscriptDaoImp");
        cocAutoService.exportMan(maid,title,response.getOutputStream());

        out.clear();
            out = pageContext.pushBody();

参考技术B poi 或者jxl 进行读写,直接用io流输出即可.
