What do you mean by “hook”? PatternConverters are plugins. If you are using
the PatternLayout and need to wrap the message then the pattern would look like
“%wrapper{%msg}” where wrapper is the key you assigned your PatternConverter.
The RegexReplacementConverter works in a similar fashion.
You could wrap the whole pattern this way if you want - “%wrapper{[%-5level]
%c{1.} %msg%n}”. The pattern converter doesn’t actually have to do any
conversion. It can call your DAO and then return the string it was operating on.
