struts的ActionForward能设成excel文件吗

Question

没这么写过，不知LZ要干什么，在新页面打开EXCEL文件？

Answer 1

java 流输出一个文件 就可以提示保存 文件 去查一下资料

Answer 2

在你的Action中加上,试试:
servletResponse.addHeader("content-type",
                                      "application/vnd.ms-excel;");
servletResponse.addHeader("Content-Disposition",
                                      "attachment; filename=" +
                                      "test.xls");
            servletResponse.addHeader("content-length",
                                      Integer.toString(Content.length));
            try {
                servletResponse.getOutputStream().write(Content);
            } catch (IOException ex) {
                //
            }
Content是你要写的文件的byte[]形式.

Answer 3

解决！try {
response.reset();
response.setContentType("application/vnd.ms-excel");
                //使用jxl
                Workbook wb = Workbook.getWorkbook(file);
// 创建可写入的Excel工作薄对象
jxl.write.WritableWorkbook wwb = Workbook.createWorkbook(response.getOutputStream(), wb);
... } catch (FileNotFoundException e) { logger.error("<=== 没找到excel文件 ===>");
} catch (Exception e) { logger.error("<=== 无法生成excel文件 ===>");
} return null;

用poi包读写excel.保存到服务器某个目录下.action中,用response.sendredirect("path")可以
