Question

poi导出excel时,导出路径为手动可选的

到处方法 用的下面这个
public class ExportExcel<T> {
public void exportExcel(String[] headers, Collection<T> dataset,
OutputStream out) {
exportExcel("测试POI导出EXCEL文档", headers, dataset, out, "yyyy-MM-dd");
}

@SuppressWarnings("unchecked")
public void exportExcel(String title, String[] headers,
Collection<T> dataset, OutputStream out, String pattern) {}

Answer 1

假如你用的server端是servlet，程序可以加入以下code：
response.setContentType("application/vnd.ms-excel");
ServletOutputStream out = response.getOutputStream();

//加入你poi写excel的代码……

out.flush();
out.close();
