I have read the source code of FileUploadInterceptor.
I think it do the message getting in it's private method, and dose not
use the maximumSize as a message format param.
So I believe there is no simple way to "extract interceptor interceptor param".
The simplest way I known is, hard coding the value in your message
properties file, like:
struts.messages.error.file.too.large=File {1} is {3} bytes which
exceeds the maximum 100123.
It is a little ugly, but looks like the only way.
The other way is, create a new class extend from
FileUploadInterceptor, and override the error message building part,
add the maximumSize as a message format param.
But it need many code, I don't think this issue is worth doing so may work.
