During program execution, if we encounter the following exception:: Stream closed.
That is, the stream has been closed, and we can easily know the reason after analyzing it, that is, the stream has been closed. Then the most likely scenario is that you have closed Stream several times.
For example:
try {
InputStream is = new xxx();
// other codes
(); //The first time I close the inputStream
} catch(IOException e) {
} finally
{
(); //Close inputStream again, which will cause Stream closed exception
}Solution: Remove the extra close statement.
Similarly, it is the same in jsp or servlet. If you close out multiple times, this exception will also be thrown, and the solution is the same!
Note: The contents in finally{} will definitely be executed! ! !
