Ralph,
My intention is basically to replace all "\n" in the message with the
ThreadContext for our application.
I think RegexReplacement is not taking variables for pattern and
substitution.
I am using the following in pattern-layout, but the substitution is not
happening correctly, and also by looking at the code, it looks like code do
not support.
<PatternLayout>
<pattern>%-5p | %X | %d{MM-dd-yyyy HH:mm} |%10sn |
%replace{%msg}{\n}{%%X{host}}%n</pattern>
RegexReplacement class do not have any information about the context, so
it cannot resolve %X{host} for substitution string.
public String format(final String msg) {
return pattern.matcher(msg).replaceAll(substitution);
}
this could be as follows
public String format(final String msg, String paramSubstitution)
{
// substitution should be formatted with the formatter, and then
passed to this method.
return pattern.matcher(msg).replaceAll(paramSubstitution);
}
