为什么我在这个循环中收到java.io.IOException？
我已经编写了下面的代码块，它拾取一个纯文本文件，如果文件上的当前修改日期大于循环的最后一次迭代，则将该文件解析为HTML版本，并将其上载到ftp服务器。我相信这个问题与作者有关，但我不明白这里发生了什么。循环的第一次迭代似乎执行得很好，然后休眠5分钟并抛出以下错误：为什么我在这个循环中收到java.io.IOException？,java,stream,ioexception,writer,Java,Stream,Ioexception,Writer,我已经编写了下面的代码块，它拾取一个纯文本文件，如果文件上的当前修改日期大于循环的最后一次迭代，则将该文件解析为HTML版本，并将其上载到ftp服务器。我相信这个问题与作者有关，但我不明白这里发生了什么。循环的第一次迭代似乎执行得很好，然后休眠5分钟并抛出以下错误： java.io.IOException: Stream closed at java.io.BufferedWriter.ensureOpen(BufferedWriter.java:116) at java.io.Buffered
