throws Exception in finally blocks
I typically use one of the closeQuietly
methods in org.apache.commons.io.IOUtils
:
public static void closeQuietly(OutputStream output) {
try {
if (output != null) {
output.close();
}
} catch (IOException ioe) {
// ignore
}
}
If you're using Java 7, and resource
implements AutoClosable
, you can do this (using InputStream as an example):
try (InputStream resource = getInputStream()) {
// Use the resource.
}
catch( Exception ex ) {
// Problem with the resource.
}
I usually do it like this:
try {
// Use the resource.
} catch( Exception ex ) {
// Problem with the resource.
} finally {
// Put away the resource.
closeQuietly( resource );
}
Elsewhere:
protected void closeQuietly( Resource resource ) {
try {
if (resource != null) {
resource.close();
}
} catch( Exception ex ) {
log( "Exception during Resource.close()", ex );
}
}
