在jsp中用java语言生成excel时,虽然对功能没有影响,但在后台会报个小错误:
getOutputStream() has already been called for this response java getOutputStream()
在网上搜了一下,找到了解决办法:
out.clear();
out=pageContext.pushBody();
加上这两行代码就可以了。
OutputStream os = response.getOutputStream();
WritableWorkbook wwb = Workbook.createWorkbook(os);
要加在wwb.close()之后,os.close()之前.....
问题产生原因:未能找到,希望高手告诉一下。
