导出时自由选择路径的代码如下:

1、后台输出Excel文件代码:

OutputStream output = response.getOutputStream()

response.reset()

response.setHeader("Content-disposition", "attachment filename=" + path)

response.setContentType("Content-Type:application/vnd.ms-excel ")

wb.write(output)

output.close()

2、前端代码:

window.open("getExcelList","_blank")
