1、jsp页面代码:
<button type="button" class="btn btn-danger btn-optional oper-box-btn-export-common">导出到Excel
</button>
2、js中的请求代码:
$(".oper-box-btn-export-common").click(function(){var flag=confirm("是否确定将查询的通用参数导出Excel表格?");
if(flag == false){
return;
}
location.href="${ctp}/para/excel/export/common";
});
3、controller中的代码:
@RequestMapping("/excel/export/common")
public void exportExcelCommon(HttpServletRequestrequest, HttpServletResponse response )throws IOException{
List<TParams> list = new ArrayList<>()
List<TParams> params = paramService.getlist()
for (TParams tParams : params) {
list.add(tParams)
}
HSSFWorkbook wb = paramService.exportCommon(list)
response.setContentType("application/vnd.ms-excel")
response.addHeader("Content-Disposition", "attachment;filename="+ java.net.URLEncoder.encode("通用参数列表", "UTF-8")+".xls")
OutputStream outputStream = response.getOutputStream()
wb.write(outputStream)
outputStream.flush()
outputStream.close()
}
