--------------------------------------
Summary: extend "Logger" with fluent API to simplify logging calls
with additional information (via MDC)
Key: SLF4J-424
URL: https://jira.qos.ch/browse/SLF4J-424
Project: SLF4J
Issue Type: Improvement
Components: Core API
Reporter: Christian Lorenz
Assignee: SLF4J developers list
Hi,
In our project we use SLF4J with Logback and logstash-logback-encoder. To use
the advantages of ELK (Logstash) we set fields via MDC within the processing
flow, but sometimes we also want to create custom fields (by using MDC) just
for a single log message. Unfortunately the SLF4J Logger API does not provide a
easy way to do that.
To improve the API I've started implementing a fluent API to log messages.
[https://github.com/jackhammer2k/slf4j/commit/f3e768260b6f109d1f207e43c48e8ca10bde28e3?diff=split]
The approach should not affect the performance, but increases readability and
extensibility.
The message builder can be extended for other stuff as well, but this is enough
for us at least.
To avoid breaking all existing implementations I changed the module name to
"slf4j-api-jdk8" and implemented so far unused methods like "info()" as
"default" interface methods.
The idea is to provide that extra package as an alternative for all Java 8
applications that want to replace their "slf4j-api" dependency. Like other
libraries provide backwards-compatible versions for old JDKs. Its fully
compatible with the whole SLF4J ecosystem.
The module will be developed in the branch "slf4j-api-jdk8" forever. Thus
during a release all modules will be released, master merged and only this
module released from the branch as well.
I would really like to see this extension within SLF4J instead of continuing
with an own "extension library" used only internally.
So far I've implemented just the info() method to show the idea, but if its
accepted to be part of officiel SLF4J I will continue with the implementation.
Cheers,
Christian
