Answer 1

因为刚写IO流的时候就断开连接了，所以会报这个异常。解决方法是将ouputStream.flush();
和ouputStream.close();写在finally{}中。希望我的回答可以帮到你

Answer 2

从你贴的Exception trace上看，没有看到Excel的类，也没有看到你自己写的类。因此从这段Exception记录中看不到问题所在。

你最好能进行Debug，看看代码在你的哪一行代码出错，也许你就自己解决了。如果还没有解决，可以把你的代码发给我看看本回答被网友采纳

Answer 3

要不是你没有到io包 不行就throw 异常 把这个异常扑捉一下 就可以了 现在报的就是io 异常 缺少输出流 OutputBuffer 你可能是少到包了
